Hello Cisco Team,
I have a switch that is increasing the input error for an interface in Down status. Below you will fin some data about this interface.
The switch is a WS-CBS3120G-S v12.2(52)SE
Gi1/0/9 down down host:SRV-09|if:eth0
I've tried to reset the counters with the commands below, however, the 'input error' is still increasing:
clear controllers ethernet-controller gi1/0/9 and
clear counter g1/0/9
Also, I've tried to perform a shu/no shutdown in the port without success, note that the input error is with the value 220 (days after the reset counters):
show interfaces Gi1/0/9
GigabitEthernet1/0/9 is down, line protocol is down (notconnect)
Hardware is Gigabit Ethernet, address is 6cfa.8930.1b89 (bia 6cfa.8930.1b89)

Do you know what could be causing this behavior? Or what else I can check for further troubleshooting?
Thanks!
