mac-address: Specifies the MAC address in an ARP entry, in the format of H-H-H. vlan-id: Specifies the ID of a VLAN to which a static ARP entry belongs, in the range of 1 to 4094. The VLAN must already exist. interface-type interface-number: Specifies the interface type and interface number. vpn-instance vpn-instance-name: Specifies the MPLS L3VPN for a static ARP entry. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. The VPN instance must already exist. To specify a static ARP entry on the public network, do not specify this option. Usage guidelines A static ARP entry is manually configured and maintained. It does not age out and cannot be overwritten by any dynamic ARP entry. Static ARP entries can be classified into long and short static ARP entries. A short static ARP entry contains an IP-to-MAC mapping. A long static ARP entry contains an IP-to-MAC mapping, a VLAN, and an output interface. A static ARP entry is effective when the device works correctly. However, if the VLAN or VLAN interface to which an ARP entry corresponds is deleted, the entry is deleted if it is long. If it is short and resolved, the entry becomes unresolved. A resolved short static ARP entry might become unresolved upon certain events. For example, it is unresolved if the output interface is down. A long static ARP entry is ineffective when the corresponding VLAN interface or output interface is down. An ineffective long static ARP entry cannot be used to forward packets. The Ethernet interface following the vlan-id argument must belong to the VLAN. You must first create the VLAN interface of the VLAN. If you specify both the vlan-id and ip-address arguments, the IP address of the specified VLAN interface must be in the same network as the specified IP address. If you do not specify any VPN, the undo arp command only removes ARP entries for the public network. Examples # Configure a static ARP entry that comprises IP address 202.38.10.2, MAC address 00e0-fc01-0000, and output interface Ten-GigabitEthernet 1/1/5 in VLAN 10. system-view [Sysname] arp static 202.38.10.2 00e0-fc01-0000 10 Ten-GigabitEthernet 1/1/5 Related commands • display arp • reset arp arp timer aging Use arp timer aging to set the aging timer for dynamic ARP entries.
