R211x-HP Flexfabric 11900 Layer 3 - IP Services Command Reference

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 a 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 interface card in slot 1 to learn up to 64 dynamic ARP entries.
<Sysname> system-view
[Sysname] arp max-learning-number 64 slot 1
arp multiport
Use arp multiport to configure a multiport ARP entry.
Use undo arp to remove a multiport ARP entry.
Syntax
arp multiport ip-address mac-address vlan-id [ vpn-instance vpn-instance-name ]
undo arp ip-address [ vpn-instance-name ]
Default
No multiport ARP entries are configured.

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.
vlan-id: Specifies a VLAN for the multiport ARP entry, in the range of 1 to 4094.
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN for the multiport ARP entry. The
vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. The specified VPN instance
must already exist. Without this option, the multiport ARP entry belongs to the public network.
Usage guidelines
The specified VLAN must already exist. If the specified VLAN or the corresponding VLAN interface is
removed, the multiport ARP entry is also removed.
The specified IP address must reside on the same subnet as the virtual interface of the specified VLAN.
Otherwise, the multiport ARP entry does not take effect.
To use the multiport ARP entry, you must also configure a multicast or multiport unicast MAC address
entry that has the same MAC address and VLAN ID as the multiport ARP entry to specify multiple output
interfaces.
