I asked about the Broadcom NICs because we have a couple of servers here that spew out gratuitous ARP packets...
The servers with the Broadcom NICs are on one subnet, and our VoIP phones are on another. Still, these two (so far) servers spew out gratuitious ARP packets. SO, when a phone boots, they get a "Duplicate IP" message. Just wondering if something similar were going on at your place... -- richard "Ralph Smith" <[email protected]> wrote on 07/19/2011 01:01:45 PM: > Unfortunately I can?t give the projector a static IP because I have > a classless subnet (255.255.252.0 mask) and the web interface on the > projector will only accept classful subnet masks.
