Switch 7700 Command reference Guide, v2.0

ARP Configuration Commands 83
Parameter
ip_address: Enter the IP address of the ARP mapping entry.
mac_address: Enter the Ethernet 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 send
frames to this address. 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.
■ Use the undo arp static 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.
By default, the ARP mapping table is empty, and the Switch uses dynamic ARP to
maintain its address mapping.
3Com recommends that you do not use this command. A manually configured
ARP mapping table is difficult to create and maintain.
Related commands: reset arp, display arp, debugging arp.
Example
To establish a mapping between IP address 129.102.0.1 and MAC address
00e0-fc01-0000, and to send frames to this address through VLAN 1, Ethernet
port 1/0/1, enter the following:
[SW7700]arp static 202.38.0.10 00e0-fc01-0000 1 Ethernet1/0/1
