8.5.1 Syntax

discard []

8.5.2 Description

Discard is a PPP LCP packet type, which is like the Echo packet type but does not
generate a return. This can be used for more careful tests of data transfer on the link,
for instance at sizes near the negotiated MRU.
This command sends an LCP Discard packet, of the specified size. If no size is given,
a minimal sized packet is sent.
Arrival of a Discard packet is logged locally as a level 2 event.
The link must be up and operational in order to do the discard test.

8.6 echo

8.6.1 Syntax

echo []

8.6.2 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 sends an LCP Echo packet, of the specified size. If no size is given, a
minimal sized packet is sent. If a size greater than the remote Maximum Receive
Unit size is specified, the value is reduced to the remote MRU before sending.
The command waits for 1 second for a reply packet to arrive, and prints whether the
reply arrived. If a reply arrives subsequent to this, it is logged as a level 2 event.
The link must be up and operational in order to do the echo test.

8.7 echo every

8.7.1 Syntax

echo every

8.7.2 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.
