All things related to multicast

[Bill Owens <>]

Two updates on this. First, the campus that was having the UPS problem has 
determined, after a lot of packet sniffing, that there's a bug in their UPS 
management cards and they crash after receiving a specific SNMP GET request. 
The multicast traffic isn't implicated at all in this problem.

Second, I heard back from Digi International regarding the problem report 
that I submitted. They agreed that in retrospect they should have chosen a 
group from the admin-scoped range, but said that this was the first time 
they'd heard of the ADDP traffic escaping from a local network, since "Digi 
devices are...normally behind a firewall." Hmm. Also, they "made management 
aware of the issue", so we'll see where that goes.

Bill.
