13.7.13. <channel> lcpmaxterminate
Syntax:
<channel> lcpmaxterminate [<n>]
Description:
Set the Max-Terminate parameter for LCP. This is the maximum number of Terminate Requests that will be sent without
reply, before assuming that the peer is unable to respond. Call with no argument to find the current setting.
The default value is 2. Configuration saving saves this information.
13.7.14. <channel> llc
Syntax:
<channel> llc [1|0]
Description:
If 1, use an LLC header on the front of transmitted packets and require one on received ones. This consists of four bytes,
FE-FE-03-CF, and is required for PPP Over AAL5 (RFC 2364 p4) when using LLC encapsulated PPP. 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 LLC header, the channel goes into a ‘learned LLC’ mode and sends packets
with the LLC header. Thus, interoperation with LLC-using equipment should not normally require any configuration.
Learning occurs in this direction only. Setting
hdlc
to 0 clears this learned state.
Configuration saving does not save the learned state.
13.7.15. <channel> pvc
Syntax:
<channel> pvc [[<port>] <vpi>] <vci> [ip|mac] [listen]
<channel> pvc none
Description:
Attach an ATM PVC to the given PPP channel. The port can be specified (only for a multi-port device), and the VPI
(default is 0), and the VCI. The allowable range of port, VPI, VCI depends on the ATM driver. Normal limits are 0 only
for port, 0 only for VPI, 1..1023 for VCI. If a single argument
none
is supplied, any current connection is torn down. This
is equivalent to
svc none
on the channel. In the PPP state machine, providing a link of this form causes the link to be ‘up’.
Note that
enable
must also be used, to allow the link to become operational. The
ip
or
mac
indicates which form of data is
transported over the connection: one of IP data (controlled by the IPCP protocol), or MAC data (for BCP). If neither is
provided,
ip
is assumed. If the channel is not linked to an interface, and the channel is for IP data, the channel is linked to
interface 1. If the channel is not linked to an interface, and the channel is for MAC data, the channel is linked to interface
2. Providing a PVC setting unsets any SVC setting. See the
svc
command. It is possible for a PVC to become ‘down’ in
the PPP state machine even though the PVC is still there, for instance due to an authentication failure. If in this state, an
incoming packet will cause the PPP state machine to go ‘up’. If
listen
is specified then this is the server end of a PVC. It
will not send out PPP Configure Requests until it first receives a packet over the PVC. When a connection is torn down it
goes returns to this state. Use the
info
command to read this information.
Configuration saving saves this information. By default a channel has no connection information.
Example:
> ppp 3 pvc 3 32 ;
set channel 3 to be (VPI=3,VCI=32)
> ppp 4 pvc ;
read PVC settings for channel 4
> ppp 5 pvc 0 ;
remove any PVC settings from
channel 5
