PPP CONFIGURATION ELEMENTS
MAX TERMINATE
The number of Terminate-Request packets sent without receiving a Terminate-Ack before
assuming that the peer is unable to respond.
M
AX CONFIGURE
The number of Configure-Request packets sent without receiving a valid Configure-Ack,
Configure-Nak or Configure-Reject before assuming that the peer is unable to respond.
M
AX FAILURE
The number of Configure-Nak packets sent without sending a Configure-Ack before assuming that
configuration is not converging. Any additional Configure-Nak packets are converted to
Configure-Reject packets.
R
ESTART TIMER
Times transmissions of Configure-Request and Terminate-Request packets. Expiration of the
Restart timer causes a Timeout event, and retransmission of the corresponding Configure-Request
or Terminate-Request packet.
LCP P
ROTOCOL FIELD COMPRESSION (PFC)
Provides a way to negotiate the compression of the Data Link Layer Protocol field.
LCP A
DDRESS CONTROL FIELD COMPRESSION (ACFC)
Provides a way to negotiate the compression of the data link layer address and control fields.
R
ECEIVE SETTINGS
The receive settings for PFC and ACFC control whether (and how) the system receives PPP Packets
with PFC or ACFC. Receive setting options include:
• mandatory: requested, repeated indefinitely if NAK'd
• preferable: requested, repeated up to MaxAttempts times if NAK'd
• supported: not requested, a peer request will be ACK'd
• not supported: not requested, NAK'd if the peer requests it
S
END SETTINGS
The send settings for PFC and ACFC control whether (and how) the system sends PPP packets with
PFC or ACFC. Send setting options include:
• mandatory: requested, repeated indefinitely if NAK'd
• preferable: requested, repeated up to MaxAttempts times if NAK'd
• supported: not requested, a peer request will be ACK'd
• not supported: not requested, NAK'd if the peer requests it
IPCP A
DDRESS NEGOTIATION INITIATION
IPCP address negotiation initiation defines when IPCP will initiate “IP address” IPCP option
negotiation. The possible choices are:
• always initiate: IPCP will always initiate the IP address option negotiation (on a PPP link).
• If IP Address Unknown: IPCP will initiate the negotiation only when the peer’s IP address is
unknown (for example, the system is running in the no-security mode, or the device entry does
not have an IP address configured.
Note: The default value is “Always Initiate.”
