Configuring the maximum number of dynamic ARP
entries for an interface
An interface can dynamically learn ARP entries. To prevent an interface from holding too many ARP
entries, you can set the maximum number of dynamic ARP entries that an interface can learn. When the
maximum number is reached, the interface stops learning ARP entries.
A Layer 2 interface can learn an ARP entry only when both its maximum number and the VLAN
interface's maximum number are not reached.
To set the maximum number of dynamic ARP entries that an interface can learn:
Step
1.
Enter system view.
2.
Enter Ethernet interface view.
3.
Set the maximum number of
dynamic ARP entries that the
interface can learn.
Setting the aging timer for dynamic ARP entries
Each dynamic ARP entry in the ARP table has a limited lifetime, called aging timer. The aging timer of a
dynamic ARP entry is reset each time the dynamic ARP entry is updated. Dynamic ARP entries that are not
updated before their aging timers expire are deleted from the ARP table.
To set the age timer for dynamic ARP entries:
Command
•
Configure a long static ARP entry:
arp static ip-address mac-address vlan-id
interface-type interface-number [ vpn-instance
vpn-instance-name ]
•
Configure a short static ARP entry:
arp static ip-address mac-address [ vpn-instance
vpn-instance-name ]
Command
system-view
interface interface-type
interface-number
arp max-learning-num

Optional.
By default, a Layer 2 interface does not
limit the number of dynamic ARP entries.
A Layer 3 interface on the HP 3600 v2
EI switch series can learn up to 8192
dynamic ARP entries. A Layer 3
interface on the HP 3600 v2 SI switch
series can learn up to 2048 dynamic
ARP entries.
If the value of the number argument is set
to 0, the interface is disabled from
learning dynamic ARP entries.
