ip vlan-flooding
There might be some ARP table entries that are resolved through ARP packets, which had the Ethernet MAC SA different
from the MAC information inside the ARP packet. This unicast data traffic flooding occurs only for those packets that use
these ARP entries.
Enabling a Switch for Multicast NLB
To enable a switch for Multicast NLB mode, perform the following steps:
1 Add a static ARP entry by entering the arp ip-address multicast-mac-address command in Global configuration
mode to associate an IP address with a multicast MAC address in the switch.
CONFIGURATION mode
arp ip-address multicast-mac-address interface
This setting causes the multicast MAC address to be mapped to the cluster IP address for the NLB mode of operation of
the switch.
2 Associate specific MAC or hardware addresses to VLANs.
CONFIGURATION mode
mac-address-table static multicast-mac-address vlan vlan-id output-range interface
