in one of our server switches, a
IOS (tm) Catalyst 4000 L3 Switch Software (cat4000-I9S-M), Version
12.2(20)EWA, RELEASE SOFTWARE (fc1)System image file is "bootflash:cat4000-i9s-mz.122-20.EWA.bin"
cisco WS-C4507R (MPC8245) processor (revision 7) with 524288K bytes of memory.
we have this problem ;
we have implemented load balancing between two server. I understand that the mac adress 02:01:00:00:00:00 is used by MS load balancing service.
the problem is that there are 2 other servers which are also on load balancing, so twice the mac-adress on the switch.
so we get this following message every 5 or 6 seconds...
Nov 15 08:22:30 mon-ss-02 160771: Nov 15 09:22:29: %C4K_EBM-4-HOSTFLAPPING: Host 02:01:00:00:00:00 in vlan 403 is flapping between port Gi5/2 and port Gi 4/22 these server must be on the same vlan, and the MS load balancing service is by default on the MCS 7800 series (for cisco call manager).
is there a way to avoid this ?? thanks.
