                A textual description of the interface.
                
                A server implementation MAY map this leaf to the ifAlias
                MIB object.  Such an implementation needs to use some
                mechanism to handle the differences in size and characters
                allowed between this leaf and ifAlias.  The definition of
                such a mechanism is outside the scope of this document.
                
                Since ifAlias is defined to be stored in non-volatile
                storage, the MIB implementation MUST map ifAlias to the
                value of 'description' in the persistently stored
                datastore.
                
                Specifically, if the device supports ':startup', when
                ifAlias is read the device MUST return the value of
                'description' in the 'startup' datastore, and when it is
                written, it MUST be written to the 'running' and 'startup'
                datastores.  Note that it is up to the implementation to
                
                decide whether to modify this single leaf in 'startup' or
                perform an implicit copy-config from 'running' to
                'startup'.
                
                If the device does not support ':startup', ifAlias MUST
                be mapped to the 'description' leaf in the 'running'
                datastore.

                Systems that implement the IF-MIB use the value of this
                leaf in the 'running' datastore to set
                IF-MIB.ifAdminStatus to 'up' or 'down' after an ifEntry

                A device MAY restrict the allowed values for this leaf,
                possibly depending on the type of the interface.
                For system-controlled interfaces, this leaf is the
                device-specific name of the interface.  The 'config false'
                list interfaces/interface[name]/state contains the currently
                existing interfaces on the device.
                
                If a client tries to create configuration for a
                system-controlled interface that is not present in the
                corresponding state list, the server MAY reject
                the request if the implementation does not support
                pre-provisioning of interfaces or if the name refers to
                an interface that can never exist in the system.  A
                NETCONF server MUST reply with an rpc-error with the
                error-tag 'invalid-value' in this case.
                
                The IETF model in RFC 7223 provides YANG features for the
                following (i.e., pre-provisioning and arbitrary-names),
                however they are omitted here:
                
                 If the device supports pre-provisioning of interface
                 configuration, the 'pre-provisioning' feature is
                 advertised.
                
                 If the device allows arbitrarily named user-controlled
                 interfaces, the 'arbitrary-names' feature is advertised.
                
                When a configured user-controlled interface is created by
                the system, it is instantiated with the same name in the
                /interfaces/interface[name]/state list.

                When an interface entry is created, a server MAY

                A server implementation MAY map this leaf to the ifAlias
                MIB object.  Such an implementation needs to use some
                mechanism to handle the differences in size and characters
                allowed between this leaf and ifAlias.  The definition of
                such a mechanism is outside the scope of this document.
                
                Since ifAlias is defined to be stored in non-volatile
                storage, the MIB implementation MUST map ifAlias to the
                value of 'description' in the persistently stored
                datastore.
                
                Specifically, if the device supports ':startup', when
                ifAlias is read the device MUST return the value of
                'description' in the 'startup' datastore, and when it is
                written, it MUST be written to the 'running' and 'startup'
                datastores.  Note that it is up to the implementation to
                
                decide whether to modify this single leaf in 'startup' or
                perform an implicit copy-config from 'running' to
                'startup'.
                
                If the device does not support ':startup', ifAlias MUST
                be mapped to the 'description' leaf in the 'running'
                datastore.

                A server implementation MAY map this leaf to the ifAlias
                MIB object.  Such an implementation needs to use some
                mechanism to handle the differences in size and characters
                allowed between this leaf and ifAlias.  The definition of
                such a mechanism is outside the scope of this document.
                
                Since ifAlias is defined to be stored in non-volatile
                storage, the MIB implementation MUST map ifAlias to the
                value of 'description' in the persistently stored
                datastore.
                
                Specifically, if the device supports ':startup', when
                ifAlias is read the device MUST return the value of
                'description' in the 'startup' datastore, and when it is
                written, it MUST be written to the 'running' and 'startup'
                datastores.  Note that it is up to the implementation to
                
                decide whether to modify this single leaf in 'startup' or
                perform an implicit copy-config from 'running' to
                'startup'.
                
                If the device does not support ':startup', ifAlias MUST
                be mapped to the 'description' leaf in the 'running'
                datastore.

                A device MAY restrict the allowed values for this leaf,

                system-controlled interface that is not present in the
                corresponding state list, the server MAY reject
                the request if the implementation does not support
                pre-provisioning of interfaces or if the name refers to
                an interface that can never exist in the system.  A
                NETCONF server MUST reply with an rpc-error with the
                error-tag 'invalid-value' in this case.
                
                The IETF model in RFC 7223 provides YANG features for the

                 If the device allows arbitrarily named user-controlled
                 interfaces, the 'arbitrary-names' feature is advertised.
                
                When a configured user-controlled interface is created by
                the system, it is instantiated with the same name in the

                A server implementation MAY map this leaf to the ifAlias
                MIB object.  Such an implementation needs to use some
                mechanism to handle the differences in size and characters
                allowed between this leaf and ifAlias.  The definition of
                such a mechanism is outside the scope of this document.
                
                Since ifAlias is defined to be stored in non-volatile
                storage, the MIB implementation MUST map ifAlias to the
                value of 'description' in the persistently stored
                datastore.
                
                Specifically, if the device supports ':startup', when
                ifAlias is read the device MUST return the value of
                'description' in the 'startup' datastore, and when it is
                written, it MUST be written to the 'running' and 'startup'
                datastores.  Note that it is up to the implementation to
                
                decide whether to modify this single leaf in 'startup' or
                perform an implicit copy-config from 'running' to
                'startup'.
                
                If the device does not support ':startup', ifAlias MUST
                be mapped to the 'description' leaf in the 'running'
                datastore.

                A device MAY restrict the allowed values for this leaf,
                possibly depending on the type of the interface.
                For system-controlled interfaces, this leaf is the
                device-specific name of the interface.  The 'config false'
                list interfaces/interface[name]/state contains the currently
                existing interfaces on the device.

                system-controlled interface that is not present in the

                the request if the implementation does not support
                pre-provisioning of interfaces or if the name refers to
                an interface that can never exist in the system.  A

                The IETF model in RFC 7223 provides YANG features for the

                 If the device allows arbitrarily named user-controlled
                 interfaces, the 'arbitrary-names' feature is advertised.
                
                When a configured user-controlled interface is created by

                A textual description of the interface.
                
                A server implementation MAY map this leaf to the ifAlias
                MIB object.  Such an implementation needs to use some
                mechanism to handle the differences in size and characters
                allowed between this leaf and ifAlias.  The definition of
                such a mechanism is outside the scope of this document.
                
                Since ifAlias is defined to be stored in non-volatile
                storage, the MIB implementation MUST map ifAlias to the
                value of 'description' in the persistently stored
                datastore.
                
                Specifically, if the device supports ':startup', when
                ifAlias is read the device MUST return the value of
                'description' in the 'startup' datastore, and when it is
                written, it MUST be written to the 'running' and 'startup'
                datastores.  Note that it is up to the implementation to
                
                decide whether to modify this single leaf in 'startup' or
                perform an implicit copy-config from 'running' to
                'startup'.
                
                If the device does not support ':startup', ifAlias MUST
                be mapped to the 'description' leaf in the 'running'
                datastore.

                Systems that implement the IF-MIB use the value of this

                IF-MIB.ifAdminStatus to 'up' or 'down' after an ifEntry

                A device MAY restrict the allowed values for this leaf,
                possibly depending on the type of the interface.
                For system-controlled interfaces, this leaf is the
                device-specific name of the interface.  The 'config false'
                list interfaces/interface[name]/state contains the currently
                existing interfaces on the device.
                
                If a client tries to create configuration for a
                system-controlled interface that is not present in the
                corresponding state list, the server MAY reject
                the request if the implementation does not support
                pre-provisioning of interfaces or if the name refers to
                an interface that can never exist in the system.  A
                NETCONF server MUST reply with an rpc-error with the
                error-tag 'invalid-value' in this case.
                
                The IETF model in RFC 7223 provides YANG features for the
                following (i.e., pre-provisioning and arbitrary-names),
                however they are omitted here:
                
                 If the device supports pre-provisioning of interface
                 configuration, the 'pre-provisioning' feature is
                 advertised.
                
                 If the device allows arbitrarily named user-controlled
                 interfaces, the 'arbitrary-names' feature is advertised.
                
                When a configured user-controlled interface is created by
                the system, it is instantiated with the same name in the
                /interfaces/interface[name]/state list.

                When an interface entry is created, a server MAY

                A server implementation MAY map this leaf to the ifAlias
                MIB object.  Such an implementation needs to use some
                mechanism to handle the differences in size and characters
                allowed between this leaf and ifAlias.  The definition of
                such a mechanism is outside the scope of this document.
                
                Since ifAlias is defined to be stored in non-volatile
                storage, the MIB implementation MUST map ifAlias to the
                value of 'description' in the persistently stored
                datastore.
                
                Specifically, if the device supports ':startup', when
                ifAlias is read the device MUST return the value of
                'description' in the 'startup' datastore, and when it is
                written, it MUST be written to the 'running' and 'startup'
                datastores.  Note that it is up to the implementation to
                
                decide whether to modify this single leaf in 'startup' or
                perform an implicit copy-config from 'running' to
                'startup'.
                
                If the device does not support ':startup', ifAlias MUST
                be mapped to the 'description' leaf in the 'running'
                datastore.

                A server implementation MAY map this leaf to the ifAlias
                MIB object.  Such an implementation needs to use some
                mechanism to handle the differences in size and characters
                allowed between this leaf and ifAlias.  The definition of
                such a mechanism is outside the scope of this document.
                
                Since ifAlias is defined to be stored in non-volatile
                storage, the MIB implementation MUST map ifAlias to the
                value of 'description' in the persistently stored
                datastore.
                
                Specifically, if the device supports ':startup', when
                ifAlias is read the device MUST return the value of
                'description' in the 'startup' datastore, and when it is
                written, it MUST be written to the 'running' and 'startup'
                datastores.  Note that it is up to the implementation to
                
                decide whether to modify this single leaf in 'startup' or
                perform an implicit copy-config from 'running' to
                'startup'.
                
                If the device does not support ':startup', ifAlias MUST
                be mapped to the 'description' leaf in the 'running'
                datastore.

                corresponding state list, the server MAY reject
                the request if the implementation does not support
                pre-provisioning of interfaces or if the name refers to
                an interface that can never exist in the system.  A
                NETCONF server MUST reply with an rpc-error with the
                error-tag 'invalid-value' in this case.
                
                The IETF model in RFC 7223 provides YANG features for the

                 If the device allows arbitrarily named user-controlled
                 interfaces, the 'arbitrary-names' feature is advertised.
                
                When a configured user-controlled interface is created by
                the system, it is instantiated with the same name in the

                A server implementation MAY map this leaf to the ifAlias
                MIB object.  Such an implementation needs to use some
                mechanism to handle the differences in size and characters
                allowed between this leaf and ifAlias.  The definition of
                such a mechanism is outside the scope of this document.
                
                Since ifAlias is defined to be stored in non-volatile
                storage, the MIB implementation MUST map ifAlias to the
                value of 'description' in the persistently stored
                datastore.
                
                Specifically, if the device supports ':startup', when
                ifAlias is read the device MUST return the value of
                'description' in the 'startup' datastore, and when it is
                written, it MUST be written to the 'running' and 'startup'
                datastores.  Note that it is up to the implementation to
                
                decide whether to modify this single leaf in 'startup' or
                perform an implicit copy-config from 'running' to
                'startup'.
                
                If the device does not support ':startup', ifAlias MUST

                A device MAY restrict the allowed values for this leaf,
                possibly depending on the type of the interface.
                For system-controlled interfaces, this leaf is the
                device-specific name of the interface.  The 'config false'
                list interfaces/interface[name]/state contains the currently
                existing interfaces on the device.

                the request if the implementation does not support
                pre-provisioning of interfaces or if the name refers to
                an interface that can never exist in the system.  A

                 If the device allows arbitrarily named user-controlled
                 interfaces, the 'arbitrary-names' feature is advertised.
                
                When a configured user-controlled interface is created by

[adapted from IETF interfaces model (RFC 7223)]                                  A textual description of the interface.                                  A server implementation MAY map this leaf to the ifAlias                 MIB object.  Such an implementation needs to use some                 mechanism to handle the differences in size and characters                 allowed between this leaf and ifAlias.  The definition of                 such a mechanism is outside the scope of this document.                                  Since ifAlias is defined to be stored in non-volatile                 storage, the MIB implementation MUST map ifAlias to the                 value of 'description' in the persistently stored                 datastore.                                  Specifically, if the device supports ':startup', when                 ifAlias is read the device MUST return the value of                 'description' in the 'startup' datastore, and when it is                 written, it MUST be written to the 'running' and 'startup'                 datastores.  Note that it is up to the implementation to                                  decide whether to modify this single leaf in 'startup' or                 perform an implicit copy-config from 'running' to                 'startup'.                                  If the device does not support ':startup', ifAlias MUST                 be mapped to the 'description' leaf in the 'running'                 datastore.

Systems that implement the IF-MIB use the value of this                 leaf in the 'running' datastore to set                 IF-MIB.ifAdminStatus to 'up' or 'down' after an ifEntry                 has been initialized, as described in RFC 2863.                                  Changes in this leaf in the 'running' datastore are                 reflected in ifAdminStatus, but if ifAdminStatus is                 changed over SNMP, this leaf is not affected.

A device MAY restrict the allowed values for this leaf,                 possibly depending on the type of the interface.                 For system-controlled interfaces, this leaf is the                 device-specific name of the interface.

If a client tries to create configuration for a                 system-controlled interface that is not present in the                 corresponding state list, the server MAY reject                 the request if the implementation does not support                 pre-provisioning of interfaces or if the name refers to                 an interface that can never exist in the system.

A device MAY restrict the allowed values for this leaf,                 possibly depending on the type of the interface.                 For system-controlled interfaces, this leaf is the                 device-specific name of the interface.  The 'config false'                 list interfaces/interface[name]/state contains the currently                 existing interfaces on the device.                                  If a client tries to create configuration for a                 system-controlled interface that is not present in the                 corresponding state list, the server MAY reject                 the request if the implementation does not support                 pre-provisioning of interfaces or if the name refers to                 an interface that can never exist in the system.  A                 NETCONF server MUST reply with an rpc-error with the                 error-tag 'invalid-value' in this case.                                  The IETF model in RFC 7223 provides YANG features for the                 following (i.e., pre-provisioning and arbitrary-names),                 however they are omitted here:                                   If the device supports pre-provisioning of interface                  configuration, the 'pre-provisioning' feature is                  advertised.                                   If the device allows arbitrarily named user-controlled                  interfaces, the 'arbitrary-names' feature is advertised.                                  When a configured user-controlled interface is created by                 the system, it is instantiated with the same name in the                 /interfaces/interface[name]/state list.

[adapted from IETF IP model RFC 7277]                                  Parameters to control the autoconfiguration of IPv6                 addresses, as described in RFC 4862. Operational state data The list of configured IPv6 addresses on the interface. Top-level container for IPv6 autoconf Top-level config data for the IPv6 interface A list of mappings from IPv6 addresses to                 link-layer addresses.                                  Entries in this list are used as static entries in the                 Neighbor Cache. Top-level operational state data for the IPv6 interface The index number of the subinterface -- used to address                 the logical interface Configurable items at the subinterface level Parameters for the IPv4 address family. Parameters for the IPv6 address family. Operational state data for logical interfaces Enclosing container for VLAN interface-specific                 data on subinterfaces The list of subinterfaces (logical interfaces) associated                 with a physical interface Specify the logical aggregate interface to which                 this interface belongs Set to TRUE to request the interface to auto-negotiate                 transmission parameters with its peer interface.  When                 set to FALSE, the transmission parameters are specified                 manually. When auto-negotiate is TRUE, this optionally sets the                 duplex mode that will be advertised to the peer.  If                 unspecified, the interface should negotiate the duplex mode                 directly (typically full-duplex).  When auto-negotiate is                 FALSE, this sets the duplex mode on the interface directly. Enable or disable flow control for this interface.                 Ethernet flow control is a mechanism by which a receiver                 may send PAUSE frames to a sender to stop transmission for                 a specified time.                                  This setting should override auto-negotiated flow control                 settings.  If left unspecified, and auto-negotiate is TRUE,                 flow control mode is negotiated with the peer interface. Assigns a MAC address to the Ethernet interface.  If not                 specified, the corresponding operational state leaf is                 expected to show the system-assigned MAC address. When auto-negotiate is TRUE, this optionally sets the                 port-speed mode that will be advertised to the peer for                 negotiation.  If unspecified, it is expected that the                 interface will select the highest speed available based on                 negotiation.  When auto-negotiate is set to FALSE, sets the                 link speed to a fixed value -- supported values are defined                 by ethernet-speed identities Number of 802.1q tagged frames received on the interface Number of receive error events due to FCS/CRC check                 failure Number of fragment frames received on the interface. Number of jabber frames received on the                 interface.  Jabber frames are typically defined as oversize                 frames which also have a bad CRC.  Implementations may use                 slightly different definitions of what constitutes a jabber                 frame.  Often indicative of a NIC hardware problem. MAC layer control frames received on the interface MAC layer PAUSE frames received on the interface Number of oversize frames received on the interface Number of 802.1q tagged frames sent on the interface MAC layer control frames sent on the interface MAC layer PAUSE frames sent on the interface Specify the logical aggregate interface to which                 this interface belongs Set to TRUE to request the interface to auto-negotiate                 transmission parameters with its peer interface.  When                 set to FALSE, the transmission parameters are specified                 manually. Ethernet interface counters When auto-negotiate is TRUE, this optionally sets the                 duplex mode that will be advertised to the peer.  If                 unspecified, the interface should negotiate the duplex mode                 directly (typically full-duplex).  When auto-negotiate is                 FALSE, this sets the duplex mode on the interface directly. Enable or disable flow control for this interface.                 Ethernet flow control is a mechanism by which a receiver                 may send PAUSE frames to a sender to stop transmission for                 a specified time.                                  This setting should override auto-negotiated flow control                 settings.  If left unspecified, and auto-negotiate is TRUE,                 flow control mode is negotiated with the peer interface. Represenets the 'burned-in',  or system-assigned, MAC                 address for the Ethernet interface. Assigns a MAC address to the Ethernet interface.  If not                 specified, the corresponding operational state leaf is                 expected to show the system-assigned MAC address. When auto-negotiate is TRUE, this optionally sets the                 port-speed mode that will be advertised to the peer for                 negotiation.  If unspecified, it is expected that the                 interface will select the highest speed available based on                 negotiation.  When auto-negotiate is set to FALSE, sets the                 link speed to a fixed value -- supported values are defined                 by ethernet-speed identities Assign the access vlan to the access port.

Operational state data The list of configured IPv6 addresses on the interface. Top-level container for IPv6 autoconf Top-level config data for the IPv6 interface A list of mappings from IPv6 addresses to                 link-layer addresses.                                  Entries in this list are used as static entries in the                 Neighbor Cache. Top-level operational state data for the IPv6 interface Configuration data for routed vlan interfaces Parameters for the IPv4 address family. Parameters for the IPv6 address family. Operational state data References the configured name of the interface Options for logical interfaces representing                 aggregates Configurable items at the global, physical interface                 level Top-level container for ethernet configuration                 and state Top-level container for hold-time settings to enable                 dampening advertisements of interface transitions. Top-level container for routed vlan interfaces.  These                 logical interfaces are also known as SVI (switched virtual                 interface), IRB (integrated routing and bridging), RVI                 (routed VLAN interface) Operational state data at the global interface level Enclosing container for the list of subinterfaces associated                 with a physical interface The list of named interfaces on the device.
