Two ports are not working correctly

Hello everybody,

 

I have something really strange.

 

I have a ICX 6450 with many VLANs.

 

The 11, 13 and 15 ports are configurated in the same VLAN, I logged the console and no action is recongnize when I connect a PC to 13 or 15 port, but when I plugged a PC to the 11 port everything works properly and the logg says tha the port is connected and go up..

 

Do you have any clue.

 

Below is the sh of the ports

 

Regards

Re: Two ports are not working correctly

try these commands:

snmp-server enable traps link-up
snmp-server enable traps link-down

 they are not about logging, but alse write messages about link up/down events to local and remote logs

Re: Two ports are not working correctly

Thank you,

 

What I did is to put the switch in stack and after that the ports work properly.

 

Thank you.
