The GigabitEthernet interface down between 2 switches is down. This is part of a Ethernchannel bundle and it shows the following:
GigabitEthernetx/y is down, line protocol is down (err-disabled)
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
Full-duplex, 1000Mb/s, media type is SX
input flow-control is off, output flow-control is off
Clock mode is auto
But I cannot see anything in the 'show log' and nothing even came up in the logs for me to be able to tell when it went down. It was when i was doing a physical check that i saw that it was down. Logging is enabled.
There is no speed or duplex issue.
The inteface is configured thus:
switchport trunk encapsulation dot1q
switchport mode trunk
no ip address
rmon collection stats 160
channel-group 1 mode desirable
Please what can be the problem? Please help.
