Hi my name is Daniel and I'm work in Colombia.
We need your help with next mistake.
Jul 16 16:58:32.646 COL: %SW_MATM-4-MACFLAP_NOTIF: Host 0000.0000.c60e in vlan 1091 is flapping between port Gi0/2 and port Gi0/1
Jul 16 16:58:32.646 COL: %SW_MATM-4-MACFLAP_NOTIF: Host 0000.0000.c600 in vlan 1091 is flapping between port Gi0/2 and port Gi0/1
A Q-in-Q connection was configured on ME 3400 switches with VLAN 1091 and its client transports its traffic over this VLAN through the MPLS network.
The MAC FLAP event is presented between the LAN and WAN interface on VLAN 1091 (VLAN Q-in-Q) and only on two MACs.
The following revisions have been made and no errors are reported.
- Origin of MAC's
- Review of Loop Layer 2 in physical and logical level.
- Configuration of trunk and access ports
- Setting Q-in-Q
We ask your support with possible recommendations to solve this event or delete the Syslog event from the Switch.
