BIG-IP generates additional high availability (HA) multicast packets when the device name is changed. Running the following commands shows the duplicate multicast entries on mgmt:mgmt interface on /var/log/sodlog file # /usr/bin/cmd_sod get info
BIG-IP multiplies the number of multicast packets when the device name is changed.
-- BIG-IPs configured with Multicast failover . -- The self-device name is changed.
Restarting the sod would remove the duplicate multicast entries. #bigstart restart sod
Cleanup the multicast entries populated on old device name when the name is updated.
