Usage guidelines
Dynamic ARP entry check disables a device from supporting dynamic ARP entries with multicast
MAC addresses. The device cannot learn dynamic ARP entries containing multicast MAC addresses.
You cannot manually add static ARP entries that contain multicast MAC addresses.
When dynamic ARP entry check is disabled, ARP entries containing multicast MAC addresses are
supported. The device can learn dynamic ARP entries containing multicast MAC addresses obtained
from the ARP packets sourced from a unicast MAC address. You can also manually add static ARP
entries containing multicast MAC addresses.
Examples
# Enable dynamic ARP entry check.
<Sysname> system-view
[Sysname] arp check enable
arp check log enable
Use arp check log enable to enable the ARP logging feature.
Use undo arp check log enable to disable the ARP logging feature.
Syntax

Usage guidelines
This feature enables a device to log ARP events when ARP cannot resolve IP addresses correctly.
The log information helps administrators locate and solve problems. The device can log the following
ARP events:
•
On a proxy ARP-disabled interface, the target IP address of a received ARP packet is not one of
the following IP addresses:
ï‚¡ The IP address of the receiving interface.
ï‚¡ The virtual IP address of the VRRP group.
•
The sender IP address of a received ARP reply conflicts with one of the following IP addresses:
ï‚¡ The IP address of the receiving interface.
ï‚¡ The virtual IP address of the VRRP group.
The device sends ARP log messages to the information center. You can use the info-center
source command to specify the log output rules for the information center. For more information
about information center, see Network Management and Monitoring Configuration Guide.
The device can generate a large number of ARP logs. To conserve system resources, enable ARP
logging only when you are auditing or troubleshooting ARP events.
Examples
# Enable ARP logging.
<Sysname> system-view
[Sysname] arp check log enable
arp hardware log enable
Use arp hardware log enable to enable error logging for ARP entry deployment to hardware.
Use undo arp hardware log enable to disable error logging for ARP entry deployment to
hardware.
Syntax
arp hardware log enable [ count-limit count-limit-value ]
undo arp hardware log enable
Default
Error logging for ARP entry deployment to hardware is disabled.
Views
System view
Predefined user roles
network-admin
Parameters
count-limit count-limit-value: Specifies the maximum number of logs that can be output
per second about ARP entry deployment to hardware. If you do not specify this option, the device
outputs a maximum of 2000 logs per second about ARP entry deployment to hardware.
Usage guidelines
After the device learns ARP entries, it deploys the ARP entries to hardware for packet forwarding.
After you execute this command, the device logs the errors that occur during the deployment. The
3
logs are sent to the information center of the device. For the logs to be output correctly, you must also
configure the information center on the device. For more information about information center
configuration, see Network Management and Monitoring Configuration Guide.
Log generation occupies memory. As a best practice, enable this feature only when traffic forwarding
is abnormal for troubleshooting.
If the maximum number of logs that can be output per second is reached, no new error logs will be
output.
Examples
# Enable error logging for ARP entry deployment to hardware and set the maximum number of logs
that can be output per second to 100.
<Sysname> system-view
[Sysname] arp hardware log enable count-limit 100
arp mac-interface-consistency check enable
Use arp mac-interface-consistency check enable to enable interface consistency
check between ARP and MAC address entries.
Use undo arp mac-interface-consistency check enable to disable interface
consistency check between ARP and MAC address entries.
Syntax
arp mac-interface-consistency check enable
undo arp mac-interface-consistency check enable
Default
Interface consistency check between ARP and MAC address entries is disabled.

network-admin
Usage guidelines
In an unstable network, the receiving interface for packets from a user might change. The interface in
the MAC address entry can be updated immediately while the interface in the ARP entry cannot. In
this case, the packets matching the ARP entry will be sent out of an incorrect interface. To solve this
problem, you can use this feature to periodically check the interface consistency between the ARP
and MAC address entry for a user. If the interfaces are not the same, ARP sends ARP requests in the
VLAN of the ARP entry and updates the entry with the ARP reply receiving interface.
Use the display mac-address command to display MAC address entries.
Examples
# Enable interface consistency check between ARP and MAC address entries.
<Sysname> system-view
[Sysname] arp mac-interface-consistency check enable

Parameters
max-number: Specifies the maximum number of dynamic ARP entries for an interface. The value
range is 0 to 163840.
alarm alarm-threshold: Specifies an alarm threshold for dynamic ARP learning, in percentage.
The value range for the alarm-threshold argument is 1 to 100. The device generates a log
message when the number of dynamic ARP entries learned on an interface reaches the value
calculated by using the formula: (max-number × alarm-threshold)/100. If you do not specify
the alarm threshold, the device does not generate log messages.
Usage guidelines
An interface can dynamically learn ARP entries. To prevent an interface from holding too many ARP
entries, you can set the maximum number of dynamic ARP entries that the interface can learn. When
the maximum number is reached, the interface stops learning ARP entries.
When the number argument is set to 0, the interface is disabled from learning dynamic ARP entries.
Examples
# Specify VLAN-interface 40 to learn a maximum of 10 dynamic ARP entries.
<Sysname> system-view
[Sysname] interface vlan-interface 40
[Sysname-Vlan-interface40] arp max-learning-num 10

Parameters
max-number: Specifies the maximum number of dynamic ARP entries for a device. The value
range is 0 to 163840.
slot slot-number: Specifies an IRF member device by its member ID.
Usage guidelines
A device can dynamically learn ARP entries. To prevent a device from holding too many ARP entries,
you can set the maximum number of dynamic ARP entries that the device can learn. When the
maximum number is reached, the device stops learning ARP entries.
When the number argument is set to 0, the device is disabled from learning dynamic ARP entries.
Examples
# Set the ARP learning limit to 64 for slot 1.
<Sysname> system-view
[Sysname] arp max-learning-number 64 slot 1
arp mode uni
Use arp mode uni to configure a port as a customer-side port.
Use undo arp mode to restore the default.
6
Syntax
arp mode uni
undo arp mode
Default
A port operates as a network-side port.
Views

Predefined user roles
network-admin
Usage guidelines
By default, a port operates as a network-side port. The device associates an ARP entry with routing
information when the interface learns an ARP entry. The ARP entry provides the next hop
information for routing.
When the port operates as the customer-side port, the device will not associate the routing
information with the learned ARP entries, thus saving hardware resources.
The maximum number of dynamic ARP entries that a customer-side port can learn might be different
from that on a network-side port. Select an appropriate operating mode for a port according to the
port location in your live network.
Examples
# Configure VLAN-interface 2 as a customer-side port.
<Sysname> system-view
[Sysname] interface vlan-interface 2
[Sysname-Vlan-interface2] arp mode uni
arp multiport

Use undo arp to delete an ARP entry.
Syntax
arp multiport ip-address mac-address { vlan-id | vsi-interface
vsi-interface-id vsi vsi-name } [ vpn-instance vpn-instance-name ]
[ description text ]
undo arp ip-address [ vpn-instance-name ]
Default

Parameters
ip-address: Specifies an IP address for the multiport ARP entry.
mac-address: Specifies a MAC address for the multiport ARP entry, in the format of H-H-H.
7
vlan-id: Specifies a VLAN for the multiport ARP entry, in the range of 1 to 4094. The specified
VLAN must already exist.
vsi-interface vsi-interface-id: Specifies a VSI interface by its number. The VSI
interface must already exist.
vsi vsi-name: Specifies a VSI by its name, a case-sensitive string of 1 to 31 characters.
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance to which the
multiport ARP entry belongs. The vpn-instance-name argument represents the VPN instance
name, a case-sensitive string of 1 to 31 characters. The specified VPN instance must already exist.
To specify a multiport ARP entry on the public network, do not specify this option.
description text: Specifies the description for the multiport ARP entry, a case-sensitive string
of 1 to 255 characters.
Usage guidelines
For easy identification of multiport ARP entries, you can configure a description for each multiport
ARP entry.
If the corresponding VLAN, the VSI, the VSI interface, or the VLAN interface is deleted, the multiport
ARP entry is also deleted.
To make the multiport ARP entry effective for packet forwarding, you must configure a multicast or
multiport unicast MAC address entry to specify multiple output interfaces. The MAC address entry
must have the same MAC address, VSI, and VLAN ID as the multiport ARP entry. In addition, the IP
address in the multiport ARP entry must reside on the same subnet as the VLAN interface of the
specified VLAN.
The VSI and VSI interface in a multiport ARP entry identify a VXLAN IP gateway. If the VSI interface
is not the gateway interface for the VSI, the multiport ARP entry configuration fails. For more
information about VSI interfaces and VSIs, see VXLAN Configuration Guide.
When you configure multiport ARP entries in an overlay network, first specify VSI gateway services
for a service loopback group.
Examples
# Configure a multiport ARP entry that contains IP address 202.38.10.2 and MAC address
00e0-fc01-0000 in VLAN 10.
