The echo reply packets that originate from host B expertise exactly the same issue once the MAC deal with entry for host A ages on Swap 2.
An incorrect port channel configuration can result in the flap of error messages because of the host MAC handle. It is because in the load-balancing character of port channeling.

If the packet is not an IGMP message, the switch CPU regenerates the packet and sends the packet to all router ports. Mainly because HSRP works by using the identical destination multicast address, all HSRP packets ought to first be sent on the change CPU, which then regenerates and sends the packets to all router ports. For that reason, if you troubleshoot HSRP challenges, disable CGMP leave processing involving HSRP friends.
Once you make use of the track command beneath the HSRP method, Cisco recommends that you use a particular decrement price so that you can avoid the HSRP flap.
The STANDBY-3-DIFFVIP1 error concept takes place when You can find interVLAN leakage thanks to bridging loops inside the change.

Reasons which include scholarship, research, or schooling could also qualify as transformative works by using as the function is the subject of overview or commentary.
The most her comment is here typical triggers for that go of MAC addresses are spanning tree troubles or Bodily layer issues.
