5.16.2.16 arp-timeout
Table 140 arp-timeout command
5.16.2.17 local-age
Table 141 local-age command
Item Description
Syntax arp-timeout seconds
no arp-timeout
Context configure>service>vpls>interface
Description This command configures the minimum time, in seconds, an ARP entry learned on the IP
interface is stored in the ARP table. ARP entries are automatically refreshed for the below
scenarios:
• When an ARP request or gratuitous ARP is seen from an IP host
• If traffic is alive for this ARP then around the last 60 seconds of its timeout ARP will be
refreshed. This ARP refresh will not occur if arp-timeout is configured between 1 and 90
If the arp-timeout value is set to 0 seconds, ARP aging is disabled.
When the lease-populate command is 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, 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
Item Description
Syntax local-age seconds
no local-age
Context configure>service>vpls
Description Specifies the aging time for locally learned MAC addresses in the forwarding database (FDB)
for the v-VPLS instance. In a v-VPLS service, MAC addresses are associated with a Service
Access Point (SAP). MACs associated with an SAP are classified as local MACs.
Like in a Layer 2 switch, learned MACs can be aged out if no packets are sourced from the
MAC address for a period of time (the aging time). In each VPLS service instance, there are
independent aging timers for local learned MAC and remote learned MAC entries in the FDB.
The local-age timer specifies the aging time for local learned MAC addresses.
The no form of this command returns the local aging timer to the default value.
Default 300 — Local MAC addresses aged after 300 seconds.
