For connecting multimode fiber there is some functionality available in cisco like UDLD and loopguard, what about on extreme switches?

Hi Alok, Im no sure of this is the same as UDLD, but extreme has ELRP.

HI Alok

you can use the below commands to see if there is RX or TX errors

sh port rxerrors port-number
sh port txerrors port-number

for a specific port use like this
sh port 1:2 txerrors
sh port 1:2 rxerrors
