104Command Sets for Command Line Interface

6.<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.

7.<channel> enable

Syntax:

<channel> enable

Description:

Set the enable flag for a PPP channel. By default this is disabled.

In the PPP state machine, this flag sets the PPP link to ‘open’. If it is already open, there is no effect.

Configuration saving saves this information. By default all channels are disabled.

8.<channel> hdlc

Syntax:

<channel> hdlc [10]

Description:

If 1, use an HDLC header on the front of transmitted packets and require one on received ones. This consists of two bytes, FF-03, and assists in interoperability with some other (non-standard) implementations. If 0, disable this. Call with no argument to find the current setting.

The default value is 0 (disabled). Configuration saving saves this information.

If not set, and a packet is received with an HDLC header, the channel goes into a ‘learned HDLC’ mode and sends packets with the HDLC header. Thus, interoperation with HDLC-using equipment should not normally require any configuration. Learning occurs in this direction only. Setting hdlc to 0 clears this learned state.
