Cisco IP Phone 7961 - PC Ports Stop Working

[garrelhasp]

Hello All,

We deployed approximately 400 Cisco 7961 IP Phones last year.

We have noticed recently that the 10/100/1000 PC ports have been failing (approximately 20 phones). Even after clearing the phone and re-configuring them, they PC port is still not functioning.

Yes, the PC port is enabled on the phone.

Unfortunately I cannot find any discussions regarding this issue.

Any thoughts?

Thanks,

Phil....

What switch are you connecting these phones to? What Phone load are you using? Have you tried disabling LLDP on the phone (Settings > Device Configuration > Network Configuration)? If the upstream switch doesn't know about LLDP, then you might see the PC port get disabled. The latest IP Phone loads come with LLDP enabled.
