Arp Timer Aging - 3Com 7750 Series Command Reference Manual

3Com Switch 7750 Series
Command Reference Guide – ARP
mac-address: MAC address contained in the ARP mapping entry to be created, in the
format of H-H-H.
vlan-id: ID of the VLAN to which the static ARP entry belongs, in the range of 1 to 4094.
interface-type: Type of the port to which the static ARP entry belongs.
interface-number: Number of the port to which the static ARP entry belongs.
Description
Use the arp static command to create a static ARP mapping entry.
Use the undo arp command to remove an ARP mapping entry.
The system ARP mapping table is empty when a switch is just started. And the dynamic
address mapping entries are generated by ARP.
Note that:
Static ARP mapping entries are valid as long as the Ethernet switch operates.
However, an ARP mapping entry is removed if the corresponding VLAN is
removed. By default, a dynamic ARP mapping entry remains valid for 20 minutes.
As for the arp static command, the value of the vlan-id argument must be the ID of
an existing VLAN, and the port identified by the interface-type and
interface-number arguments must belong to the VLAN.
Related command: reset arp, display arp.
Example
# Create a static ARP mapping entry, with the IP address of 202.38.10.2, the MAC
address of 00e0-fc01-0000. The ARP mapping entry belongs to Ethernet1/0/1 port
(assuming that Ethernet1/0/1 port belongs to VLAN1).
