tagged packets on untagged port

Hi,

I have created a vlan which servers as master vlan for ESRP, let's call it esrpmaster. I have added ports to this vlan tagged that work fine and one untagged port, and assigned an ip address to the vlan.

I am unable to ping upstream extreme switch connected to the untagged port. Mirroring the port and running wireshark releveals that while the other side sends me untagged packets, I send them tagged packets, even though I have added the port to erpmaster vlan as untagged.

I am confused why this is happening. Anyone got a clue? All switches involved are x670v, and I am running 15.3.1.4

Best regards,

Dimitris (from dzila)

Found my answer in the documentation:

'Egress mirrored traffic always egresses the monitor port tagged'

So that was a red herring. I have no idea why the switches cannot ping each other now.

Thank you for your reply,

No, I mean master vlan, control vlan is for EAPS which I do not use... (from dzila)

Do you mean by master vlan, control vlan? If yes, all ports added to this vlan must be tagged. One of the ESRP (or EAPS) rules. (from LNU)
