The Vaultas switch has been configured to participate in spanning-tree, so it won't blindly go along with loops any more.  Sorry.

The Vaultas switch didn't make the loop, it just made it worse.  Any word on the origination of the loop?

Got ssh, that mac doug sent out belongs to Vaultas.

There are two Extreme networks on the Mankato Remote switch, Vaultas
and Revnet. I don't have ssh right now, can someone check?

Nobody turned up recently.

A better measure is who turned up on the switch rather than the route-server.
This was a l2 flood, not anything in routing.

No ports were up/down on the switch until the flood triggered
my port and Implex's port offline (probably the same class of cisco switch
protecting themselves from the l2 flood).

Feb 19 15:11:45  MICE-SW1 mib2d[1107]: SNMP_TRAP_LINK_DOWN: ifIndex 604, ifAdminStatus up(1), ifOperStatus down(2), ifName ge-1/0/3
Feb 19 15:11:48  MICE-SW1 mib2d[1107]: SNMP_TRAP_LINK_DOWN: ifIndex 606, ifAdminStatus up(1), ifOperStatus down(2), ifName ge-1/0/5

So, it probably was from one of the existing remote switches.

The MAC address I posted about before is an Extreme? switch.


Also, the l2 flood seems abated.

I've been pinging clear to the route servers for 5 minutes now.
