Trunk between 6248 and 8132

Try a different port to see if this is isolated to just 1/0/9. How long is this cable? possible to try a different cable?

It definitely is not negotiating. If the physical connection is good, then perhaps test manually setting the speed and duplex on the port.

console(config)#interface tengabitethernet 1/0/9
console(config-if)#speed 10000
console(config-if)#duplex full

Can always check logging for any pertinent information. Physically unplug and then plug the cable back in, then check logs.

console# show logging

You can also try to manually bring the interface down and then bring it back up. 

console(config)#interface tengabitethernet 1/0/9
console(config-if)#shut
console(config-if)#no shut

Daniel,

Thanks for your reply. I just tried to set speed and duplex and the link is still down. The cable length should be more than 10 meters - not sure about exact. 

I am currently not onsite, will try another port or another cable later. 

Thanks again.

Glad to hear it was a simple port mixup. While troubleshooting, I prefer testing connectivity from client to client. This provides a better overall picture of connectivity to the network. Can you post up your current running configs? I can help look at the configuration for any suggested changes. 

Daniel,

The issue was actually caused by a wrong port - it should be port number 1 instead of 9 on 8132 side. Now both sides link states are UP. On 8132 side:

However, the two switches connected via the trunk cannot ping each other. Do you have any suggestion of the issue here? The fiber length between them is 20 meters. But now link status on both sides are UP. 

Thanks in advance.
