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. The specified VLAN must already exist.
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.
Usage guidelines
If the VLAN or the corresponding 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 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.
Examples
# Configure a multiport ARP entry that contains 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
