keepalive <seconds>
Use the keepalive command to enable the transmission of keepalive packets on the interface and specify
the time interval in seconds between transmitted packets.
Syntax Description
<seconds> Defines the time interval (in seconds) between transmitted keepalive packets
(valid range: 0 to 32,767 seconds).
Default Values
By default, the time interval between transmitted keepalive packets is 10 seconds.
Applicable Platforms
This command applies to the NetVanta 300, 1000R, 2000, 3000, 4000, and 5000 and Total Access 900
Series units.
Command History
Release 1.1 Command was introduced.
Functional Notes
If three keepalive packets are sent to an interface with no response, the interface is considered down. To
detect interface failures quickly, specify a smaller keepalive time.
Usage Examples
The following example specifies a keepalive time of 5 seconds on the virtual PPP interface:
(config)#interface ppp 1
(config-ppp 1)#keepalive 5
