Re: EX2200 lost management interface after ethernet loop

Just in case someone's watching, I found another switch in this state.

From your list:

1) Yes

2) No, times out

3) See below

4) No relevant logs (I found this switch many weeks after it went missing on the network)

Also, the down/up cycle didn't help either.

Also interesting, the management interface seems to have ARP entries for remote systems even though it won't actually use them.
