Wired Intelligent Edge

Hi all,

I'm working on a case to bring up the trunk link between HP procurve 2610 series. The fiber port is UP and i could see the Bytes TX/RX is increasing but nothing for unicast RX/TX packets. Checked through all the required configuration already in place. Can you pls share if you have experience on this and how to check further and resolve this issue? Thanks.

Appreciate your comments.

What is spanning tree status on both sides?
Your figures might be normal for an STP blocked link

Thanks for response, but the setup is only 1 uplink to the main switch and no redundancy thus i don't see spanning-tree is blocking since only single uplink.

What is port config on both sides?   Do VLANs on both sides and their setting (tagged vs untagged ) correspond?

Its a Fiber connection. (Tranceiver swapped but still same). Yeah, vlans(Tagged untagged) & configuration already double confirmed is alright. This is standard config we use on many sites but issue only happen when deploying this site.

Show us the config for both switches, makre sure relevant interfaces have "description" set so we know what they are for.

Show spanning-tree on each switch.

show log on each switch.
