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.
