Parameters

None

Description

Use the arp check enable command to enable the ARP entry checking function, that is,

to disable the switch from creating multicast MAC address ARP entries.

Use the undo arp check enable command to disable the ARP entry checking function.

In this case, the switch can create multicast MAC address ARP entries.

By default, the ARP entry checking function is enabled.

Examples

# Enable the switch to create multicast MAC address ARP entries.

received ARP packets in the VLAN to which it belongs.

Use the undo arp non-flooding command to disable this feature.

By default, the feature is disabled.

Parameters

None

Description

Use the arp proxy enable command to enable proxy ARP.

Use the undo arp proxy enable command to disable proxy ARP.

I. In VLAN view:

By default, the proxy ARP function is disabled.

You can configure the command for sub-VLANs only. After you enable proxy ARP for a

sub-VLAN, the sub-VLAN directly forwards received ARP requests to other proxy

enabled sub-VLANs in the same super VLAN.

Command Manual – ARP

H3C S9500 Series Routing Switches Chapter 1 ARP Configuration Commands

1-3

II. In VLAN interface view:

By default, proxy ARP is disabled.

After receiving an ARP request, the device directly sends back an ARP response if the

following three requirements are satisfied:

z The source IP address of the ARP request and that of the receiving interface are

on the same network segment.

z The target IP address of the ARP request is on another network segment.

z The route corresponding to the target IP address of the ARP request exists, and

the outgoing interface of the route is not the receiving interface of the ARP

request.

Related commands: display arp proxy.

Use the undo arp local-proxy enable command to disable local proxy ARP.

After enabled with local proxy ARP, when receiving an ARP request, the device sends

back an ARP response directly if the sender and target IP addresses of the ARP

request are on the same network segment as the receiving interface.

Related commands: display arp proxy.

Examples

# Enable local proxy ARP on VLAN-interface 2.

1.1.5 arp static

Syntax

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

[ vpn-instance vpn-instance-name ]

undo arp ip-address

View

System view

Parameters

ip-address: IP address of the ARP entry.

mac-address: MAC address of the ARP entry, in the format H-H-H ( H indicates a

hexadecimal number).

vlan-id: VLAN to which the static ARP entry belongs, in the range of 1 to 4094.

interface-type interface-number: Type and number of the port to which the static ARP

entry belongs. For information about these two arguments, refer to the description on

the interface command in Ethernet Port Command Manual.

vpn-instance vpn-instance-name: VPN instance name in MPLS VPN.

Description

Use the arp static command to configure a static ARP entry in the ARP table.

Use the undo arp static command to delete a static ARP entry from the ARP table.

By default, the ARP table is empty and the switch can obtain ARP entries through

dynamic ARP.

Command Manual – ARP

H3C S9500 Series Routing Switches Chapter 1 ARP Configuration Commands

1-5

The arp static command can be used to configure auto-fill of ARP entries. When

configuring an ARP entry, if you input only the IP address, the switch will automatically

set the MAC address to 0. Such an ARP entry is an auto-fill ARP entry. When an

auto-fill ARP entry is resolved, the switch can automatically fill the learned MAC

address into the entry.

Note that:

z When the switch works normally, its static ARP entries remain valid unless you

perform operations that invalidate ARP entries, such as changing or removing

VLAN interfaces, removing a VLAN, or removing a port from a VLAN. These

operations will cause the corresponding ARP mapping entries to be automatically

removed.

z The vlan-id argument must be the ID of an existing VLAN, and the Ethernet port

specified behind this argument must belong to the VLAN.

z The vpn-instance-name argument must be the VPN-instance name of an existing

MPLS VPN.

z The port specified in an ARP entry can only be a manually aggregated port,

instead of a statically or dynamically aggregated port.

z If the mac-address of an ARP entry is a multicast MAC address, the system will

take this ARP entry as a multicast ARP entry.

z Automatic fill-in of MAC addresses is enabled only after IP address protection is

enabled on the interface.

z Once a MAC address is filled in, an auto-fill ARP entry becomes a common static

ARP entry and cannot be filled in again.

Related commands: reset arp, display arp, debugging arp.

Examples

# Configure an ARP entry with the MAC address 000f-e201-0000 and IP address

202.38.10.2. This static ARP entry is on Ethernet 2/1/1 in VLAN 1.

vpn-instance-name ]

View

Command Manual – ARP

H3C S9500 Series Routing Switches Chapter 1 ARP Configuration Commands

1-6

Parameters

ip-address: IP address of the ARP entry.

mac-address: MAC address of the ARP entry, in the format of H-H-H. For a

multi-outgoing-port ARP entry, this is a multicast MAC address.

vlan-id: ID of the VLAN of the static ARP entry, in the range of 1 to 4094.

interface-type interface-number: Type and number of a port. For information about

these two arguments, refer to the interface command in Ethernet Port Command

Manual.

vpn-instance-name: Instance name of the VPN which the IP address belongs to.

Description

Use the arp static multi-port command to add a port for a static multicast ARP entry. If

the entry does not exist, the command generates the ARP entry.

Use the undo arp multi-port command to remove a port from the multicast ARP entry.

When you remove the last port, the system removes the multicast ARP entry.

The multicast ARP feature allows you to associate a common unicast route to a Layer 2

multicast group by creating a static multicast ARP entry. In this way, a packet matching

the entry can be forwarded out multiple ports. In brief, a multicast ARP entry is a static

ARP entry with a multicast MAC address and corresponds to multiple ports.

You can use the multi-port keyword to add a port for a multicast ARP entry. Only one

port can be added every time the command is executed. If the same port exists, the

switch will not add the port.

Note that:

z Up to 64 multicast ARP entries are supported, with each entry having up to 100

outgoing ports. A manual port aggregation group is considered a single port.

z An outgoing port of a multicast ARP entry can be a manually aggregated port or a

common port, but cannot be a statically or dynamically aggregated port.

z As specified in the IEEE 802.3ad standard, if a port is disabled but the dynamic

port aggregation function is enabled, the port is not an aggregated port, but a

common one. Therefore, the port can be configured as a port for a multicast ARP

entry. After the port is enabled, the port becomes a dynamically aggregated port

and will be removed from the multicast ARP entry.

z If a port with a number smaller than those in an aggregation group (for example,

the port is on an interface card with a smaller slot number) is added into the group,

the ports in this aggregation group will be removed from multicast ARP; while

other ports will not be affected.

z For an aggregation of ports on different interface cards, if removing an interface

card with a smaller slot number can cause primary port switchover, doing so will

remove the ports of this aggregation group from multicast ARP; while other ports

will not be affected.

Command Manual – ARP

H3C S9500 Series Routing Switches Chapter 1 ARP Configuration Commands

1-7

z If an aggregation group is removed, ports in this group are removed from multicast

ARP; while other ports are not affected.

z No matter the state of the primary port in an aggregation is up or down, ports in the

aggregation group will not be removed from multicast ARP.

You can add multiple ports one by one for a static multicast ARP entry. To view the

configuration, use the display arp multi-port command.

Related commands: reset arp, display arp, debugging arp, arp static.

Examples

# In a multicast ARP entry, the IP address is 10.10.10.98, and the MAC address is

0150-0098-0098. Add the outgoing ports Ethernet 6/1/1, Ethernet 6/1/2 and Ethernet

11/1/3 to the ARP entry.
