4 ARP Configuration Commands

ARP Configuration Commands

arp check enable

Syntax

arp check enable

undo arp check enable

View

System view

Default Level

2: System level

Parameters

None

Description

Use the arp check enable command to enable ARP entry check. With this function enabled, the AP

cannot learn any ARP entry with a multicast MAC address, and you cannot configure such a static ARP

entry with a multicast MAC address on the AR; otherwise, the system displays error messages.

Use the undo arp check enable command to disable the function. After ARP entry check is disabled,

the AP can learn the ARP entry with a multicast MAC address, and you can also configure such a static

ARP entry on the AP.

By default, ARP entry check is enabled.

Examples

# Enable ARP entry check.

<Sysname> system-view

[Sysname] arp check enable

4-2

arp max-learning-num

Syntax

arp max-learning-num number

undo arp max-learning-num

View

Ethernet interface view, VLAN interface view

Default Level

2: System level

Parameters

number: Maximum number of dynamic ARP entries that an interface can learn, in the range of 0 to 256.

The default value is 256.

Description

Use the arp max-learning-num command to set the maximum number of dynamic ARP entries that an

interface can learn.

Use the undo arp max-learning-num command to restore the default.

Examples

# Specify VLAN-interface 40 to learn up to 30 dynamic ARP entries.

<Sysname> system-view

[Sysname] interface vlan-interface 40

[Sysname-Vlan-interface40] arp max-learning-num 30

arp static

Syntax

arp static ip-address mac-address [ vlan-id interface-type interface-number ]

undo arp ip-address

View

System view

Default Level

2: System level

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: Interface type and interface 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:

4-3

z A static ARP entry is effective when the AP 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.

z 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 interface following the argument must belong to

that VLAN. The VLAN interface of the VLAN must have been created.

z If both the vlan-id and ip-address arguments are specified, the IP address of the VLAN interface

corresponding to the vlan-id argument must belong to the same network segment as the IP

address specified by the ip-address argument.

Related commands: reset arp and display arp.

Examples

# Configure a static ARP entry, with the IP address being 202.38.10.2, the MAC address being

00e0-fc01-0000, and the outbound interface being Ethernet 1/0/1 of VLAN 10.

Description

Use the arp timer aging command to set the age timer for dynamic ARP entries.

Use the undo arp timer aging command to restore the default.

By default, the age timer for dynamic ARP entries is 20 minutes.

Related commands: display arp timer aging.
