R0106-HP MSR Router Series Layer 3 - IP Services Command Reference(V7)

3
VLAN interface view
Predefined user roles
network-admin
Parameters
number: Specifies the maximum number of dynamic ARP entries for an interface.
The following matrix shows the value ranges and default values for the number argument:
Hardware Value ran
g
e Default
MSR2000 0 to 4096 4096
MSR3000 0 to 4096 4096
MSR4000 0 to 16384 16384
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 a maximum of 500 dynamic ARP entries.
<Sysname> system-view
[Sysname] interface vlan-interface 40
[Sysname-Vlan-interface40] arp max-learning-num 500
# Specify GigabitEthernet 2/1/1 to learn a maximum of 1000 dynamic ARP entries.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/1/1
[Sysname-GigabitEthernet2/1/1] 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.
