HPE 5920 series User Manual

Usage guidelines
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 the interface can learn. When
the maximum number is reached, the interface stops learning ARP entries.
When the number argument is set to 0, the interface is disabled from learning dynamic ARP entries.
Examples
# Specify VLAN-interface 40 to learn a maximum of 500 dynamic ARP entries.
<Sysname> system-view
[Sysname] interface vlan-interface 40
[Sysname-Vlan-interface40] arp max-learning-num 500
# Specify Ten-GigabitEthernet 1/0/1 to learn a maximum of 1000 dynamic ARP entries.
<Sysname> system-view
[Sysname] interface Ten-GigabitEthernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] arp max-learning-num 1000
# Specify Layer 2 aggregate interface bridge-aggregation 1 to learn a maximum of 1000 dynamic
ARP entries.
<Sysname> system-view
[Sysname] interface bridge-aggregation 1
[Sysname-Bridge-Aggregation1] arp max-learning-num 1000
# Specify Layer 3 aggregate interface route-aggregation 1 to learn a maximum of 1000 dynamic ARP
entries.
<Sysname> system-view
[Sysname] interface route-aggregation 1
[Sysname-Route-Aggregation1] arp max-learning-num 1000
arp max-learning-number
Use arp max-learning-number to set the maximum number of dynamic ARP entries that a device
can learn.
Use undo arp max-learning-number to restore the default.
Syntax
arp max-learning-number number slot slot-number
undo arp max-learning-number slot slot-number
Default
A device can learn a maximum of 16384 dynamic ARP entries.

Parameters
number: Specifies the maximum number of dynamic ARP entries for a device. The value range is 0
to 16384.
slot slot-number: Specifies an IRF member device by its member ID or a PEX by its virtual slot
number.
