Hi Pari,

I did a quick test in lab
In my scenario the port 1 is not part of the VLAN labpc so no ELRP packets were transmitted, so there may not be any effect due to this but a mis-configuration i suppose.

"show elrp"
Pkts Pkts Disable
Client Vlan Ports Int. Count Cyclic Xmit Rcvd Action Port (sec)
--------------------------------------------------------------------------------
CLI uplink 1 1 0 Yes 17 0 L -
CLI labpc 1 1 0 Yes 0 0 L -

Thanks 4 info!

Which one is best recommended practice port wise config in Vlan in elrp or vlan all option?

I can enable ELRP port (all) instead of port wise and I excluded the uplink port from elrp.
My question is even trunk port allowed that vlan it will not affect right because i gave elrp vlan all port.

Hi Pari,

Yes it is best to enable ELRP for all ports and exclude the uplink ports so that ELRP will not disable the uplink ports in case of a remote loop.

Hi,

ELRP can now be added to ports in VLANs that are not yet active on the port, to allow ELRP to work with dynamic VLAN assignment via netlogin. This will result in the ELRP warning from the question, but is a valid use-case.

Thanks,
Erik
