Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
9.3(0.0) Added the support for association of an IP address with multicast MAC address on the
MXL platform.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
For multicast mode of NLB, to associate an IP address with a multicast MAC address in the switch, use address
resolution protocol (ARP) by entering the arp ip-address multicast-mac-address command in Global
conguration mode. This setting causes the multicast MAC address to be mapped to the cluster IP address for
NLB mode of operation of the switch.
You cannot use Class D or Class E IP addresses or zero IP address (0.0.0.0) when creating a static ARP. Zero MAC
addresses (00:00:00:00:00:00) are also invalid.
Although static ARP entries take precedence over dynamically-learnt ARP entries, a static ARP entry that points to
a wrong port is not included in the FIB or ARP entries.
