Hi
on several 2950 Catalysts I see on most interfaces that the "False carrier errors" is counter rather high. The rest of the counters look allright to me.
Port configuration is as follows:
interface FastEthernet0/2
switchport access vlan 5
switchport mode access
speed 100
duplex full
no snmp trap link-status
spanning-tree portfast
spanning-tree bpduguard enable
This is the output you get from the "show controllers ethernet-controllers" command:
