Commands
speed (for 10/100/1000 interfaces) — sets the link speed to 10, 100, 1000 or auto-
negotiate the speed.
keepalive
Send keepalive packets periodically to keep an interface alive when it is not transmitting data.
S4820T
Syntax
keepalive [seconds]
To stop sending keepalive packets, use the no keepalive command.
Parameters
seconds (OPTIONAL) For SONET interfaces with PPP encapsulation
enabled, enter the number of seconds between keepalive
packets. The range is from 0 to 23767. The default is 10
seconds.
Defaults Enabled.
