I have a pair of cisco 4500x-32 and i configured VSS between then but i am using just 1x 10G interface for fast-hello packet and here is that interface configuration:
interface TenGigabitEthernet1/1/2 description VSS-Fast Hello dual-active fast-hello end
I want to have redundancy for this interface, so i can execute "dual-active fast-hello" on another 10G interface for the fast-hello packages, or Shall i bundle both ports are port-channel then issue "dual-active fast-hello" command under port-channel interface?
if we should not use port-channel and we should have two phsycally interface with "dual-active fast-hello" under their configuration, Do they working as redundancy? my mean is if the first port goes down, Is the second port responsible for the fast-hello packets?
