[c-nsp] What happens during the "shutdown" and "no shutdown" to a 1000BASE-LX10 port

[Pierre Emeriaud]

Hi Terence, Martin,


err-disabled is indeed a plausible possibility, but IIRC, it should
visible from a show int in the form:

switch# sh int Gi1/0/7
GigabitEthernet1/0/7 is down, line protocol is down (err-disabled)

and the sh int status that Martin did should have showed it, which was
not the case:
Port      Name               Status       Vlan       Duplex  Speed Type
Gi0/24    -> Brocade         connected    trunk      a-full a-1000
1000BaseLX SFP


Useful commands
- sh int status err-disabled
- sh log | i BPDU|err-disable
