Cisco VSS Dual-active PAgP detection via Nexus and vPC

[Olle Johansson]

Hi!

We will soon implement Cisco nexus 5595 in our Datacenter.

However we will still be using a pair of C6500 in a VSS in some part of the network.

Today we are running dual-active detection via a PAgP Port-channel, but those Port-channels will be removed and the only Port-channel we will have is to a pair of Nexus 5596.

Does anyone know if we can run PAgP dual-active detection via this MEC/vPC?

Thank you for your time!

Hi,

The easies way is to connect both links from the 6500s to only one of the Nexus switches. Than create a portchannel on both the 6500 and the Nexus.

The other option would be to connect the 6500s directly together via a gig link and use fast hello instead of epagp.

I would use fast hello since it is supported on the 6500s.

Hi!

I forgott to mention that the both VSS chassies are placed in 2 location about 2km apart and we would like to not use any more fiber.

Otherwise that would be the best solution
