Types of Mutations. Knowing a few basic types of mutations can help you understand why some mutations have major effects and some may have no effect at all. Substitution. A substitution is a mutation that exchanges one base for another (i.e., a change in a single chemical letter such as switching an A to a G).Such a substitution could: 1  change a codon to one that encodes a different amino acid and cause a small change in the protein produced.nowing a few basic types of mutations can help you understand why some mutations have major effects and some may have no effect at all.

The Switch Virtual Interface (SVI) represents a logical interface between the bridging function and the routing function of a VLAN in the device. SVI can have members that are physical ports, direct port channels, or virtual port channels. The SVI logical interface is associated with VLANs, and the VLANs have port membership. The SVI state does not depend on the members. The default auto state behavior for SVI in Cisco APIC is that it remains in the up state when the auto state value is disabled.
7-layer OSI MODEL. The OSI (Open System Interconnection) model is developed by ISO in 1984 to provide a reference model for the complex aspects related to network communication. It divides the different functions and services provided by network hardware and software in 7 layers.
