Port-Security Issues

[alanbatres]

Hi.

I have a problem with one Catalyst 3560 V2, i have a 7911 IP Phone and a PC attached to it, when enable port security on that port the PC and IP Phone works perfectly, after shutdown the and turn on again the PC loss the connection, the IP Phone register without problems, i saw the port security interface and the Security Violation Count remain in 0 also i don't have any err-disable on the port, when check the mac addres table and search the mac address of the PC i realize that doesn't exist in the table even when the port has the mac address sticky.

I change the port, change the port-security parameters but the problem continues, i have to shut / no shut to the port and then works fine but in the next day the problem appears again.

Any suggestions.

Regards.

Hi Erasmo,

There is a bug for a similar case in 3750: https://tools.cisco.com/bugsearch/bug/CSCta67777

I would check the release notes for the IOS version and check if there is a caveat related with this. If you find something proceed with the upgrade recommended, and if you don´t upgrade it as well.

Regards,

Jose.
