102CHAPTER 5: USING NETWORK PROTOCOL COMMANDS

MAC address. Use the undo arp check enable command to disable the checking of ARP entry so the device learns the ARP entry where the MAC address is a multicast MAC address.

By default, the checking of ARP entry is enabled and the device does not learn the

ARP entry where the MAC address is a multicast MAC address.

Example

Configure that the device learns the ARP entry where the MAC address is multicast MAC address.

Parameters

ip_address Enter the IP address of the ARP mapping entry.

mac_address Enter the MAC address of the ARP mapping entry, in the format H-H-H (H indicates a four digit hexadecimal number, for example 00e0-fc01-0000).

vlan_id Enter the ID number of the local VLAN that you want to use to associate with the ARP mapping entry. The VLAN ID can be in the range 1 to 4094. Optional.

interface_type Enter the type of the port that you want to use to send frames to this address. Optional, but must be entered if a VLAN ID is specified.

interface_number Enter the number of the port that you want to use to send frames to this address. Optional, but must be entered if a VLAN ID is specified.

Description

Use the arp static command to manually configure the static ARP mapping entries in the ARP mapping table. You must enter an IP address and MAC address with this command. You can optionally enter a VLAN ID, which also requires entry of an interface type and interface number. An aggregation port or port with LACP enabled cannot be set as the egress port of static ARP.

Use the undo arp ip_address command to remove a static ARP mapping entry from the ARP table.

To remove all static ARP entries, use the reset arp static command. Note that the reset arp static command removes all static ARP entries permanently.
