Microsoft Server Cluster: IP Cluster

Enable and Disable VLAN Flooding

• ARP entries already resolved through the VLAN are deleted when the feature is enabled. This ensures
that ARP entries across the VLAN are consistent.
• All ARP entries learned after the feature is enabled are deleted when the feature is disabled, and RP2
triggers ARP resolution. The feature is disabled with the command
• When a port is added to the VLAN, the port automatically receives traffic if the feature is enabled. Old
ARP entries are not deleted or updated.
• When a member port is deleted, its ARP entries are also deleted from the CAM.
• Port channels in the VLAN also receive traffic.
• There is no impact on the configuration from saving the configuration.
• The feature is not reflected in the output of the
command
The ARP entries exist in the secondary RPM CAM, so failover has no effect on the feature.
