arp max-learning-num
Use
arp max-learning-num
to set the dynamic ARP learning limit on an interface.
Use
undo
arp max-learning-num
to restore the default.
Syntax
arp max-learning-num max-number
[
alarm
alarm-threshold
]
undo arp max-learning-num
Default
The default value for the dynamic ARP learning limit on an interface is 1024.
Views
Layer 2 Ethernet interface view
Layer 2 aggregate interface view
VLAN interface view
Predefined user roles

Parameters
max-number
: Specifies the maximum number of dynamic ARP entries for an interface.The value
range for this argument is 0 to 1024.
alarm
alarm-threshold
: Specifies an alarm threshold for dynamic ARP learning, in percentage.
The value range for the
alarm-threshold
argument is 1 to 100. The device generates a log
message when the number of dynamic ARP entries learned on an interface reaches the value
calculated by using the formula: (
max-number
×
alarm-threshold
)/100. If you do not specify
the alarm threshold, the device does not generate log messages.
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 10 dynamic ARP entries.
<Sysname> system-view
[Sysname] interface vlan-interface 40
[Sysname-Vlan-interface40] arp max-learning-num 10
# Specify GigabitEthernet 1/0/1 to learn a maximum of 10 dynamic ARP entries.
