PPPoA Commands
E-DOC-CTC-20040210-0030 v1.0
encaps The WAN protocol encapsulation to be used on this interface.
Choose between:
• vcmux
• llc.
The default is vcmux.
OPTIONAL
pcomp Try (on) or do not try (off) to negotiate PPPoA protocol compression
(LCP PCOMP). The default is off.
OPTIONAL
accomp Try (on), do never try (off) or negotiate (negotiate) to negotiate PPPoA
address & control field compression (LCP ACCOMP).
In most cases, LCP ACCOMP should not be disabled nor negotiated, i.e.
the address field FF-03 should not be sent over ATM. Therefore by default
this parameter is enabled (on).
If the accomp parameter is set to 'negotiate', the local side of the PPPoA
connection demands to do ACCOMP and adapts itself to the result of this
negotiation.
OPTIONAL
trace Enable (on) or disable (off) verbose console logging.
The default is off.
OPTIONAL
auth Select the authentication protocol.
Choose between:
• pap:
Password Authentication Protocol (PAP) authentication will be
forced
• chap:
Challenge Handshake Authentication Protocol (CHAP) authentica-
tion will be forced
• auto:
CHAP authentication will be used. If CHAP authentication is not
successful, PAP authentication will be used instead.
The default is auto.
OPTIONAL
restart Automatically restart the connection when Link Control Protocol (LCP)
link goes down (on) or do not restart automatically (off).
The default is off.
OPTIONAL
retryinterval A number between 0 and 65535 (seconds).
Represents the intermediate interval between two retries to establish the
connection on ATM level. The default is 10.
OPTIONAL
passive Put the link in listening state in case LCP times out (on) or not (off).
This parameter allows to determine whether the link should be left open
to wait for incoming messages from the remote side after 10 unsuccessful
tries to establish the connection or not. The default is off.
OPTIONAL
silent Do not send anything at startup and just listen for incoming LCP messages
(on) or retry up to 10 times to establish the connection (off).
The default is off.
OPTIONAL
echo Send LCP echo requests at regular intervals (on) or not (off).
The default is on.
