We have 2 x Catalyst 6807 switches in a Quad-Supervisor VSS setup in which one 10 Gigabit link from each supervisor make current VSL-link between the switches. So in total we have 20 Gbit between the two switches.
The Sup6T supervisors in each 6807 has 2 x 40 Gbit ports. This means we have 4 x 40Gbit ports in each switch to use. We are interested in using these 40Gbit ports to upgrade the VSL-link from 20 Gbit to 80 Gbit.
Is there a way to do this without any downtime or breaking the current VSS or VSL-link?
Could we set up new VSL port-channels to deal with the 40Gbit ports from each side, connect them together while the old 10Gbit links are still up and running? And then remove the 10 Gbit cabling if everything looks okay in CLI.
Is there any reason behind, why you are not choosing the path to by adding new links to same port-channel and remove the old links. ? just thought.
Yes you are correct, i miss read that, i was in impression all in same speed links, Let me think how can be done with out service interruption or split brain.
