Configuring Arp; Configuring A Static Arp Entry; Configuring The Maximum Number Of Arp Entries For An Interface - 3Com S7906E Configuration Manual

Usually ARP dynamically resolves IP addresses to MAC addresses, without manual intervention.
To allow communication with a device using a fixed IP-to-MAC mapping, configure a
non-permanent static ARP entry for it. To allow communication with a device through a specific
interface and using a fixed IP-to-MAC mapping, configure a permanent static ARP entry for it.

Configuring ARP

Configuring a Static ARP Entry

A static ARP entry is effective when the device works normally. However, when a VLAN or VLAN
interface to which a static ARP entry corresponds is deleted, the entry, if permanent, will be deleted,
and if non-permanent and resolved, will become unresolved.
Follow these steps to configure a static ARP entry:
To do...
Enter system view
Configure a permanent
static ARP entry
Configure a
non-permanent static
ARP entry
The vlan-id argument must be the ID of an existing VLAN which corresponds to the ARP entries. In
addition, the Ethernet interface following the argument must belong to that VLAN. A VLAN
interface must be created for the VLAN.
The IP address of the VLAN interface corresponding to the vlan-id argument must belong to the
same network segment as the IP address specified by the ip-address argument.

Configuring the Maximum Number of ARP Entries for an Interface

Follow these steps to set the maximum number of dynamic ARP entries that an interface can learn:
To do...
Enter system view
Enter Ethernet interface view
Use the command...
system-view
arp static ip-address
mac-address vlan-id
interface-type interface-number
[ vpn-instance
vpn-instance-name ]
arp static ip-address
mac-address [ vpn-instance
vpn-instance-name ]
Use the command...
system-view
interface interface-type
interface-number
1-4
