I'm having an odd issue. I'm running 6509's using Sup 1's running 6.3(3) CatOS with MSFC-1's using IOS ver 12.1(2)E. Yes it's old.
Every now and then Windows XP workstations, both DHCP and statically assigned, detects a duplicate IP. I searched for a rogue DHCP server and there wasn't any. The logs in the MSFC didn't indicate a duplicate IP nor did I see any with test equipment.
The fix, not a solution, was I rebooted my 6509's. Once that was done the issue cleared up.
Does anyone have any theories as to why this might be?
