Arp Multiport - HPE 5920 series Command Reference Manual

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 IRF member device in slot 1 to learn a maximum of 64 dynamic ARP entries.
<Sysname> system-view
[Sysname] arp max-learning-number 64 slot 1

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 instance 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 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 VLAN interface of the specified
VLAN. Otherwise, the multiport ARP entry does not take effect.
To use the multiport ARP entry, 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 and VLAN ID as the multiport ARP entry.
Examples
# Configure a multiport ARP entry that comprises IP address 202.38.10.2 and MAC address
00e0-fc01-0000 in VLAN 10.
<Sysname> system-view
[Sysname] arp multiport 202.38.10.2 00e0-fc01-0000 10
