Virtual Wiki. ToR switch placement â not at the top! You may know about ToR, top-of-rack (for) switches. Itâs the practice of placing a physical switch within each rack, so that the network switching for the rack is close to the servers or devices that need to connect to it. The ToR switches will allow servers to communicate with each other directly, and therefore reduces overall traffic on core switching.
With this vPC-HM there are 3 options on how the port-channeling is done. This is configured on the port-profile of type Ethernet that is used by the physical NICs on your ESX/ESXi servers. The command used for this is: channel-group auto mode active | passive| on [mac-pinning or cdp]. 1  mac-pinning.2  load-balances the available links (i.e. port-channel) based upon mac-address of the VM.3  So VM1 will flow through say vmnic0 and VM2 will flow through vmnic1, where vmnic0 and vmnic1 is this vPC-HM port-channel.i, For uplink port channels in 1000v, I am seeing mac-pinning chosen in many best practice guides when used in Cisco UCS. However, I have not been able to find any documentation why mac-pinning is infact better choice than VPC-HM for deploying 1000v within VMware vSphere on UCS.
