Hi Guys,
I would really appreciate if some can help me solve this?
I am trying to reorganize the ports on the cisco 3560g switch.
The trunk port for the UC500 is connected to port 3 on the 3560g
I have reconfigure port 1, identical to port 3, but when I swap the cable to port 1, I cannot connect to the UC500, but if I move the cable back to port 3 I am able to connect.
I did a shut no shut, with no success
Attach is the uc config and the 3560g
The trunk port on the uc500 is port 8
Thanks,
Lake

Hi
if you remove the monitor statement in your config i think it will do better.
monitor session 1 source interface Gi0/22
monitor session 1 destination interface Gi0/1
This sets the interface Gi0/1 into a state where it will not forward anything to the switch but it mirrors the source interface ie Gi0/22 in this case.
This means the interface will send out traffic that comes to and/or from port Gi0/22 and light up just as it should, but no traffic will pass from the connected device in Gi0/1 to and through the switch.
As an extra tip to avoid this types of errors, when i set up a monitor port and i am not using it iset a broken RJ45 connector without any copper pegs in it to show that this port is not to be used.
Good luck

Dumb question. How long do you wait before saying it's broken?
The trunk still has to renegotiate.
Also, the spanning-tree link type point-to-point command... I've normally seen that when using RPVST.
Since you're basically using a router on a stick deployment, there's no risk of spanning-tree loops. You can try using the spanning-tree portfast trunk command on the switch port. It'll speed up the trunk negoatiation.

On the 3560 change the speed/duplex on the 3560 to auto/auto instead of hardcoding and see what happens.

Even after waiting 10 to 15 minutes it does not work.
