7705 SAR OS Services Guide Page 373
Description This command configures the minimum interval, in seconds, that an ARP entry learned on the IP
interface is 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 the arp-timeout value is set to 0 s, ARP aging is disabled.
The no form of the command reverts to the default value.
Default no arp-timeout
Parameters seconds — the minimum number of seconds a learned ARP entry is stored in the ARP table,
expressed as a decimal integer. A value of 0 specifies that the timer is inoperative and learned
ARP entries will not be aged.
Values 0 to 65535
Default 14400 s (4 h)
bfd
Syntax bfd {transmit-interval} [receive receive-interval] [multiplier multiplier]
no bfd
Context config>service>ies>interface
Description This command configures the time interval in which BFD control messages are transmitted and
received on the interface. The multiplier parameter specifies the number of consecutive BFD
messages that must be missed by the peer node before the BFD session closes.
Default no bfd
Parameters transmit-interval — the number of milliseconds between consecutive BFD sent messages
Values 100 to 100000
Default 100
receive-interval — the number of milliseconds between consecutive BFD received messages
Values 100 to 100000
Default 100
multiplier — the number of consecutive BFD messages that must be missed before the interface is
brought down
Values 3 to 20
Default 3
Note: The 7705 SAR will attempt to refresh an ARP entry 30 s prior to its expiry. This refresh
attempt occurs only if the ARP timeout is set to 45 s or more.
