I have a printer that will appear for 3-5 pings after the port is bounced, then it disappears. I have removed all port security config from the port, upgraded the switch to newer iOS, and rebooted it. Printer works if we remove the phone from the equation. Port was never in err-disabled state (always up and up). No port security violations. Cables tested good.
What is the next step in troubleshooting this problem? I do not have physical access to the access switch or printer.
Details:
Distrib Switch (4507R+E) -> Access Switch (c3560x Poer 0/10) -> Phone (7911) -> Printer (192.168.62.15)
Access Port Config:
interface GigabitEthernet0/10
switchport access vlan 62
switchport mode access
switchport voice vlan 162
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
queue-set 2
priority-queue out
mls qos trust device cisco-phone
mls qos trust cos
auto qos voip cisco-phone
spanning-tree portfast
service-policy input AutoQoS-Police-CiscoPhone
end
Immediately after bouncing the port:
