Parameters
ip-address: Specifies an IP address for the static ARP entry.
mac-address: Specifies a MAC address for the static ARP entry, in the format of H-H-H.
vlan-id: Specifies the ID of a VLAN to which the static ARP entry belongs. The value range is 1 to
4094.
interface-type interface-number: Specifies an interface by its type and number.
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 static ARP entry
belongs. The vpn-instance-name argument represents the VPN instance name, 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 short or long.
A resolved short static ARP entry becomes unresolved upon certain events, for example, when the
resolved output interface goes down, or the corresponding VLAN or VLAN interface is deleted.
Long static ARP entries are effective or ineffective. Ineffective long static ARP entries cannot be
used for packet forwarding. A long static ARP entry is ineffective when any of the following conditions
exists:
•
The corresponding VLAN interface or output interface is down.
•
The IP address in the entry conflicts with a local IP address.
•
No local interface has an IP address in the same subnet as the IP address in the ARP entry.
If you specify the vlan-id interface-type interface-number argument, follow these restrictions and
guidelines:
•
The interface can be an Ethernet interface or an aggregate interface.
•
The VLAN and VLAN interface must already exist. The specified Ethernet interface must belong
to the specified VLAN.
•
The IP address of the VLAN interface and the IP address specified by the ip-address argument
must be on the same network.
•
A long static ARP entry in a VLAN is deleted if the VLAN or VLAN interface is deleted.
On a VXLAN IP gateway that forwards traffic among VXLANs through VXLAN tunnels, a VSI
interface can act as the gateway for multiple VXLANs. The VSI interface (input interface) might be
connected to multiple VXLAN tunnel interfaces (output interfaces). In this case, to configure a long
static ARP entry, you must specify the interface-type interface-number interface-type
interface-number vsi vsi-name parameters to identify a VSI interface-VSI-VXLAN tunnel interface
binding. For more information about VSI interfaces, VSI, and VXLAN tunnel interfaces, see VXLAN
Configuration Guide.
Examples
# Configure a long static ARP entry that contains IP address 202.38.10.2, MAC address
00e0-fc01-0000, and output interface HundredGigE 1/0/1 in VLAN 10.
