Re: OT: VSS dual active detection mechanisms

I know you can use Gig Int, I have been for over a year. :)

One other recommendation, or best practice. Spread your 10G Port channel across two different line cards. IE if you have another 10G blade use one 10G from one blade and another 10G port from another blade to be a part of the port channel bundle.

I only have the two teng's that came with my sups, so I'm not running "best practice". Uncle John (Chambers) is slightly disappointed with me.

James,

We're doing the same:

show switch virtual dual-active fast-hello
Fast-hello dual-active detection enabled: Yes

Fast-hello dual-active interfaces:
Port Local State Peer Port Remote State
---------------------------------------------------
Gi1/1/48 Link up Gi2/1/48 Link up

One thing to remember though, fast hellos are only supported if you're running SXI. I tried the ePaGP route to a stack of 3750G's running 12.2(55)SE, no luck.

Am I missing something???

Core-01#show switch virt dual-active fast-hello Fast-hello dual-active detection enabled: Yes

Fast-hello dual-active interfaces:
Port Local State Peer Port Remote State
---------------------------------------------------
Gi1/1/48 Link up Gi2/1/48 Link up

Core-01#

I think you can spare 1 Gig port per chassis (2 total). I can't even imagine the fun experienced with two active Core Switches. Sounds like an RGE to me.
