We have 6509 as backbone, 4948G as server swithces and 3560 as client switches. Yesterday 4548G switches did not work for two minutes. And produces that log:
Nov 27 14:00:46.113 TURKEY: %C4K_EBM-4-HOSTFLAPPING: Host 00:0C:6E:6E:F9:15 in vlan 106 is flapping between port Te1/49 and port Gi1/32
Every 4584G switch generated these hostflaping log. When i checked the error, cisco says: his error message appears on the switch when the switch detects the specified host address as a source address on multiple ports.
Te1/49 is trunk link to backbone(6509) and G1/32 is the of the server whose mac address is 00:0C:6E:6E:F9:15. So i understand that that mac adress advetised by another switch and then 4948 switch generated this log.
How can i find, which switch is producing this problem.
