Chapter 1  ARP Configuration Commands

1.1  ARP Configuration Commands

1.1.1  arp check enable

Syntax

arp check enable

undo arp check enable

View

System view

Parameter

None

Description

Use the arp check enable command to enable ARP entry check, preventing the device from learning multicast MAC addresses.

Use the undo arp check enable command to disable the function, allowing the device to add multicast MAC addresses into the ARP mapping table.

By default, ARP entry check is enabled.

Example

# Enable the device to add multicast MAC addresses into the ARP mapping table.

<Sysname> system-view

[Sysname] undo arp check enable

1.1.2  arp max-learning-num

Syntax

arp max-learning-num number

undo arp max-learning-num

View

VLAN interface view

Parameter

number: Maximum number of dynamic ARP entries that an interface can learn,it ranges from 1 to 2048 and defaults to 2048.

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.

Example

# 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

1.1.3  arp static

Syntax

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

undo arp ip-address

View

System view

Parameter

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: Specifies a port by its type and 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 to which an ARP entry of the device corresponds is deleted, the entry is deleted accordingly.

l           The vlan-id argument is used to configure ARP entries on the device and must be the ID of an existing VLAN. In addition, the Ethernet interfaces following the argument must belong to that VLAN.

Related command: reset arp, and display arp.

Example

# Bind the IP address 202.38.10.2 to the MAC address 00e0-fc01-0000 for GE1/0/2 of VLAN 10.

<Sysname> system-view

[Sysname] arp static 202.38.10.2 00e0-fc01-0000 10 GigabitEthernet1/0/2

# Bind the IP address 129.102.0.1 to the MAC address 00e0-fc01-0000.

[Sysname] arp static 129.102.0.1 00e0-fc01-0000
