Hi,
Posting this on behalf of someone else.
About 2 nites ago, around midnight, his network seemed like it imploded.
Its a WISP, and connected to GigabitEthernet0/1 is his "Site A" that is
192.168.25.1/24 . About 60% of the devices off the AP aren't contactable anymore.
He has GigabitEthernet1/1 that he hangs 192.168.50.1/24 (Site B) and
192.168.75.1/24 (Site C). Site B seemed to get a ripple effect for a few minutes,
but recovered. Site C didn't get touched at all.
Later that night, one of this backhauls still was able to pass data, but
you couldn't contact the device management for 4 hours.
He did a bunch of re-terminating, re-cabling, replacing equipment and
it seems to still be plaguing him. He's also said he'll plug something in, be
able to contact it for 2 minutes, then it disappears.
sounds like you created a loop.
ensure STP is enabled and ensure the right ports are set to 'portfast'.
cheers,
lineoln.
