We have a number of 4500x SFP switches in our environment. When we imported the devices into NPM they all show with a "Overall Hardware Status" - Warning state.
I checked each device and nothing is wrong with the hardware, from the case I opened with SW the issue is due to the transceiver MIB. The threshold is set low for on each device and Orion\NPM reports this as an issue.
As a fix, it was recommended that we disable the transceiver monitoring on this switch, which would then allow NPM to report this device in a Normal State.
To do this we should be able to apply the following command
'transceiver type all' and disable, this command isn't available in the switches we are using.
Just wondering if anyone else has had a similar issue and could offer any help.
