Force10 S4810 VLT – Quick Configuration sample

Hasan Mansur


I have already given a non-technical synopsis on VLT in one of my previous posts here

As mentioned, VLT Is a Dual Active Control Plane implementation, of a Multi System LAG. Cisco vPC is a similar technology.

VLT is beneficial in environments where the downstream devices like servers or access/distribution switches need to build port channels/LAGs across two separate upstream switches. in this context, VLT resembles what stacking offers. The other benefit is that due to distinct control planes, it is possible to perform maintenance one switch at a time without taking the entire fabric down. This is unlike stacking, where the entire fabric must be taken down for upgrades etc.

Here, i will provide a quick configuration sample on getting VLT operational between two VLT peer (S4810) switches.
