A.3.4 <channel> pppoe
Syntax:
<channel> pppoe [[<port>] <vpi>] <vci> [ip] [acname "<string>"][servicename
"<string>"]<channel> pppoe none
Description:
Attach an ATM PVC to the given PPP channel using the PPPoE encapsulated driver
located on the lower layer. The port can be specified (only for a multi-port device),
and the VPI (default is 0), and the VCI. This is used for the configuration of a PPPoE
localized client only. No server support is offered.
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.
In the PPP state machine, providing a link of this form causes the link to be 'up'.
Note that a following
enable
must also be used, to allow the link to become
operational. This command initiates the PPPoE Discovery Phase, which is used to
detect compatible PPPoE Access Concentrators across the link. Once the discovery
Phase is complete, the use of the
enable
command will initiate LCP over the newly
connected link.
The
ip
indicates which form of data is transported over the connection. The
ip
is
assumed if not given. If the channel is not linked to an interface, and the channel
is for IP data, the channel is linked to interface 1.
The
acname
parameter specifies that a connection may be made with a specific
remote access concentrator. This name must exactly match the following parameter
string (enclosed in quotes). If the acname name does not match, a connection will
not be made to a responding non-matching access concentrator. If no acname is
given, the client will attach to any access concentrator that responds.
The
servicename
parameter specifies our client's servicename when "discovering" an
access concentrator. This parameter is for identification purpose only, when sending
packets to the remote. If no servicename is specified, no servicename tag will be
sent to the access concentrator.
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'.
Use the
info
command to read this information.
