Is it possible to monitor c3 discards in E-Ports of Router and edge switches using port fencing feature and can we disable it when threshold breached ?
For E-Port, i see only CRC, ITW, LR, PE, ST are supported for port fencing and not C3TX_TO.
Can i use Port Type - Port for this purpose which has C3TX_TO area?
Any inputs are highly appreciated.

Yes, you can use the E-Port C3 discards under Port type which includes EX-Ports.When the threshold is reached you use port fencing to disable the affected port. But you have to be very carefull with this feature because a slow drain device could cause Tx C3 discards on ISLs (no matter if they're e-port or ex-ports) and according to this policy it would be disabled not been the originator of the issue...
