PPP Negotiation
Configuration – Network > Interfaces > Advanced> PPP n> PPP Negotiation
When PPP starts up, the devices at both ends of the link negotiate the link parameters, in
order to find a common subset that both devices can use. The negotiation may be
summarized by saying that both ends send negotiation packets that say “these are the
values that I wish to use and these are the values that I wish you to use”
Restrict the negotiation time to s seconds
The parameter in this text entry box specifies the maximum time allowed for a PPP
negotiation to complete. If negotiations have not completed in this time, the PPP instance is
disconnected.
Desired local ACCM
The value in this text box is the local Asynchronous Control Character Map which has the
default value 0x00000000. Changing this value is for advanced users.
Desired remote ACCM
This text box holds the remote ACCM which has the default value 0xffffffff. As above, the
default will work in nearly all circumstances and should be changed only where really
necessary.
Desired local MRU n bytes
The value in this text box is the desired local Maximum Receive Unit (MRU), the default
value of 1500 octets will work fine in most cases.
Desired remote MRU n bytes
The value in this text box is the desired MRU for the remote end of the link. The default
value of 1500 octets will be fine in most cases.
Request local ACFC
When checked, this checkbox causes the router to request Address Control Field
Compression (ACFC). When negotiated, the address/control fields are removed from the
start of the PPP header.
Request remote ACFC
When checked, this checkbox causes the router to ask the remote device to request ACFC.
Request local PAP authentication
When checked, this checkbox causes the router to use the Password Authentication Protocol
(PAP) before allowing a connection to be made. Generally, this parameter is enabled for
incoming connections and disabled for outgoing connections.
