mask — 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.

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.
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,
expressed as a decimal integer. A value of zero specifies that the timer is inoperative and learned
ARP entries will not be aged.
Values 0 — 65535
mac
Syntax mac ieee-address
no mac
Context config>service>vpls>interface
Description This command assigns a specific MAC address to a VPLS IP interface.
The no form of the command returns the MAC address of the IP interface to the default value.
Default The system chassis MAC address.
Parameters ieee-address — Specifies the 48-bit MAC address for the static ARP in the form aa:bb:cc:dd:ee:ff or
aa-bb-cc-dd-ee-ff where aa, bb, cc, dd, ee, and ff are hexadecimal numbers. Allowed values are
any non-broadcast, non-multicast MAC and non-IEEE reserved MAC addresses.
