I have 2x 6509 at the core with one of the cores connecting to a 2950 edge switch (each cores have 2 MSFC's). I am getting the below error message
1y37w: %STANDBY-3-DUPADDR: Duplicate address 10.44.228.164 on Vlan70, sourced by 0009.b7c8.4a01
I have checked the MAC address and it looks like it is port 1 of the 2950 switch (nothing is connected into this and I have also shut the interface down)
We have loads of 3500 series edge switches and I don't get any error messages from the MSFC's.
The version I am running
6509 - 5.5(6) CatOS
MSFC - 12.1(2)E
2950 - 12.1(6)EA2a
Any ideas - could it be OS levels?
