arp

To associate an IP address with a multicast MAC address in the switch when you configure multicast mode of the network load balancing (NLB), use the address resolution protocol (ARP).

Syntax

arp ip-address multicast-mac-address interface

To remove an ARP address, use the no arp ip-address command.

Parameters

ip-address	Enter an IP address in dotted decimal format.
multicast-mac-address	Enter a 48–bit hexadecimal address in MAC address in nn:nn:nn:nn:nn:nn format for the static MAC address to be used to switch multicast traffic..
interface	(OPTIONAL) Enter any of the following keywords and slot/port or number information: For the Management interface, enter the keyword `ManagementEthernet` then the slot/port information. The slot range is from 0 to 1 and the port range is 0. For a Port Channel interface, enter the keywords `port-channel` then a number. The range is from 1 to 128. For a 10-Gigabit Ethernet interface, enter the keyword `TenGigabitEthernet` then the slot/port information. The interface specified here must be one of the interfaces configured using the `{output-range \| output} interface` option with the `mac-address-table static` command.

Defaults

Not configured.

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 configuration 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.
