Dual-active detection for VSS via enhanced PAGP

Hello,

What is the configuration needed on an etherchannel PAGP trunk to enable dual active detection for VSS on 4500X ?

I have enabled it on my vss in global mode but I don't know which vlan to allow on the trunk towards my switch in PAGP.

Is it the native vlan that I should allow on the trunk ?

Thanks for the help

Jeremy

Hi Jeremy,

You can allow all the vlans of specific vlans under the portchannel that connects to the access switches.  Usually, best practice is to allow only the vlans you are using on that specific access switch.

Dual-active detection command is applied under the VSS domain for the specific portchannel connecting to your access switches.  It is not per vlan.

Have a look
