HP MSR2000/3000/4000 Router Series Layer 3 - IP Services Command Reference

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 an 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 up to 500 dynamic ARP entries.
<Sysname> system-view
[Sysname] interface vlan-interface 40
[Sysname-Vlan-interface40] arp max-learning-num 500
# Specify Ethernet 1/1 to learn up to 1000 dynamic ARP entries.
<Sysname> system-view
[Sysname] interface ethernet 1/1
[Sysname-Ethernet1/1] 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.
