A.3.3 <channel> echo every
Syntax:
<channel> echo every <seconds>
Description:
Echo is an LCP packet, which is used to test an established PPP link. It solicits a
ping-like reply from the far end.
This command sets a channel to confirm the continued presence of an open PPP
connection by sending an LCP echo every few seconds, and requiring an echo reply.
The number of seconds between echo requests is specified as a parameter.
If 0 is specified, the function is disabled. Use the
info all
command to read the
current state on a channel.
Configuration saving saves this information. By default, the function is disabled.
