ip-address — The IP address of the IP interface. The ip-address portion of the address command
arp-timeout
Syntax arp-timeout seconds
no arp-timeout
Context config>service>vpls>interface
Description This command configures the minimum time in seconds an ARP entry learned on the IP interface will
be stored in the ARP table. ARP entries are automatically refreshed when an ARP request or
gratuitous ARP is seen from an IP host, otherwise, the ARP entry is aged from the ARP table. If arp-
timeout is set to a value of zero seconds, ARP aging is disabled.
When the arp-populate and lease-populate commands are enabled on an IES interface, the ARP
table entries will no longer be dynamically learned, but instead by snooping DHCP ACK message
from a DHCP server. In this case the configured arp-timeout value has no effect.
The default value for arp-timeout is 14400 seconds (4 hours).
The no form of this command restores arp-timeout to the default value.
Default
14400 seconds
Parameters seconds — The minimum number of seconds a learned ARP entry will be stored in the ARP table,
mac
Syntax mac ieee-address
no mac
Context config>service>vpls>interface
Description This command assigns a specific MAC address to an IP interface.
For Routed Central Office (CO), a group interface has no IP address explicitely configured but
inherits an address from the parent subscriber interface when needed. For example, a MAC will
respond to an ARP request when an ARP is requested for one of the IPs associated with the subscriber
interface through the group interface.

specifies the IP host address that will be used by the IP interface within the subnet. This address
must be unique within the subnet and specified in dotted decimal notation. Allowed values are IP
netmask
The subnet mask in dotted decimal notation. When the IP prefix is not specified in CIDR
notation, a space separates the ip-address from a traditional dotted decimal mask. The mask
parameter indicates the complete mask that will be used in a logical 'AND' function to derive the
local subnet of the IP address. Allowed values are dotted decimal addresses in the range
128.0.0.0 – 255.255.255.252. Note that a mask of 255.255.255.255 is reserved for system IP
addresses.
expressed as a decimal integer. A value of zero specifies that the timer is inoperative and learned
ARP entries will not be aged.
