Hello,
I´ve just added the IDSM-2 blades on a 6500 and configured it but it did not work as I planned.
This picture is a little scale what I tried to do, actually I had more vlans on the inspection.
I have 2 cores and a portchannel trunk in between them and for redundancy I´m using HSRP as the config shows.
After I congfigured I´ve got these msgs and I could not figure out how to stop it:
Core1
%MAC_MOVE-SP-4-NOTIF: Host 001a.a2e4.e800 in vlan 6 is flapping between port Gi6/d1 and port Po1
%MAC_MOVE-SP-4-NOTIF: Host 001a.a2e4.e800 in vlan 7 is flapping between port Gi6/d1 and port Po1
MAC 001a.a2e4.e800 is from Core2
Core2
%MAC_MOVE-SP-4-NOTIF: Host 0022.557b.c340 in vlan 6 is flapping between port and port Po1
%MAC_MOVE-SP-4-NOTIF: Host 0022.557b.c340 in vlan 7 is flapping between port Po1 and port
Mac 0022.557b.c340 is from Core1
There was only one VLAN pair that did not have this problem, which was the VLAN L2 for the ISP router and the VLAN Outside for the FWSM . It also was the only VLAN that did not have HSRP working, I dont know if it has something to do.
The Core 1 is the STP Root with priority of Zero and the Core 2 is the Backup Root with priority 4096
Any guesses ?
