Gratuitous ARP Configuration Commands

2 Proxy ARP Configuration Commands
Proxy ARP Configuration Commands
The term switch in this document refers to a switch in a generic sense or an access controller configured with the switching function unless otherwise specified.
ARP Configuration Commands
arp check enable
Syntax
arp check enable
undo arp check enable
View
System view
Parameters
None
Description
Use the arp check enable command to enable ARP entry check. With this function enabled, the device cannot learn any ARP entry with a multicast MAC address. Configuring such a static ARP entry is not allowed either; otherwise, the system prompts error information.
Use the undo arp check enable command to disable the function. After the ARP entry check is disabled, the device can learn the ARP entry with a multicast MAC address, and you can also configure such a static ARP entry on the device.
By default, ARP entry check is enabled.
Examples
# Enable the ARP entry check function on the switch.
<Sysname> system-view
[Sysname] arp check enable
arp max-learning-num
Syntax
arp max-learning-num number
undo arp max-learning-num
View
VLAN interface view
Parameters
number: Maximum number of dynamic ARP entries that a VLAN interface can learn, in the range 1 to 2048.
Description
Use the arp max-learning-num command to set the maximum number of dynamic ARP entries that a VLAN interface can learn.
Use the undo arp max-learning-num command to restore the default.
By default, a VLAN interface can learn up to 2,048 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
arp static
Syntax
arp static ip-address mac-address [ vlan-id interface-type interface-number ]
undo arp ip-address
View
System view
Parameters
ip-address: IP address in an ARP entry.
mac-address: MAC address in an ARP entry, in the format H-H-H.
vlan-id: ID of a VLAN to which a static ARP entry belongs to, in the range 1 to 4094.
interface-type interface-number: Port type and port number.
Description
Use the arp static command to configure a static ARP entry in the ARP mapping table.
Use the undo arp command to remove an ARP entry.
Note that:
l A static ARP entry is effective when the device works normally. However, when the VLAN or VLAN interface to which an ARP entry corresponds is deleted, the entry, if permanent, will be deleted, and if non-permanent and resolved, will become unresolved.
l The vlan-id argument is used to specify the corresponding VLAN of an ARP entry and must be the ID of an existing VLAN. In addition, the Ethernet port following the argument must belong to that VLAN. The VLAN interface of the VLAN must have been created.
Related commands: reset arp, display arp.
Examples
# Configure a static ARP entry, with the IP address being 202.38.10.2, the MAC address being 000f-e201-0000, and the outbound port being GigabitEthernet 0/0/10 of VLAN 10.
<Sysname> system-view

View
System view
Parameters

Description

By default, the aging time for dynamic ARP entries is 20 minutes.
Related commands: display arp timer aging.
Examples
# Set aging time for dynamic ARP entries to 10 minutes.
