Uplink port changes to orange after 12-36 hours switch stops responding


If I unplug the cable from the uplink port and plug it back it, the switch starts responding again.


What could be causing this?

Hi,


There are some features and bugs, which could cause this. Can you provide the respective switch port configurations?

Here they are:

The log on the switch in cabinet #1 is saying:

8w2d: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/1, changed state to down

8w2d: %LINK-3-UPDOWN: Interface GigabitEthernet0/1, changed state to down

8w2d: %LINK-3-UPDOWN: Interface GigabitEthernet0/1, changed state to up

8w2d: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/1, changed state to up


Log on the switch in cabinet #2 says something similar.

1d11h: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/2, changed state to down

1d11h: %LINK-3-UPDOWN: Interface GigabitEthernet0/2, changed state to down

Hi,


The information presented does not allow to finally conclude a certain reason. Could you provide the interface configurations?

Have you checked cabling as well?

Hi,


"show run interface GigabitEthernet0/1" with the proper interface numbers.

Thanks!


On the first switch its:

show run interface GigabitEthernet0/1

Building configuration...


Current configuration : 49 bytes

!

interface GigabitEthernet0/1

duplex full

end


on the second switch its:

show run interface GigabitEthernet0/2

Building configuration...


Current configuration : 36 bytes

!

interface GigabitEthernet0/2

end


Are they suppose to be the same bytes?

Hi,


No, the number of bytes is just indicating how much data is used for storing this particular part of the configuration.


As the interfaces are in default configuration, I cannot see any reason for the observed behaviour.

Sorry not to be more helpful.
