NOTE

If authentication fails after a config modify has been executed, make sure you verify the config modify with a config show. If you see more than one ppp modem0 chap user xxx

yyydisplay for your remote interfaces with the old Router name and password, you must manually delete them with the following commands:

pppiface lcp {local remote} acfc

[on off allow [on off]]

Address and control field compression (ACFC)—Displays or sets the option to compress the address and control fields of the PPP header. The default is off.

ppp iface lcp {local remote} pfc

[on off allow [on off]]

Protocol field compression (PFC)—Displays or sets the option to compress the address and control fields of the PPP header. By default the setting is off, so that all implementations must transmit packets with two- octet PPP protocol fields. When using low-speed links, it is desirable to conserve bandwidth and avoid sending redundant data. PFC controls the trade-off between implementation simplicity and bandwidth redundancy.

ppp iface lcp {local remote} magic

[on off value allow [on off]]

Magic number - Displays or sets the initial magic number, to provide a method of detecting links in the looped-back state and other Data Link Layer anomalies. By default the magic number is off, or not negotiated, and zero is inserted where a magic number may otherwise be used. Choose the magic number in the most random manner possible in order to guarantee a very high probability that it is unique. Good ways to choose a random magic number include using machine serial numbers, network addresses, etc. Until the magic number is successfully negotiated it must be transmitted as zero.

value Enter the value you want to be the magic number.

ppp iface lcp {local remote} mru [size allow [on off]]

Maximum receive unit (MRU)—Displays or sets the maximum receive unit (MRU), the largest packet that a

PPPpeer is willing to receive. It is expressed in two octets and sent to inform the peer that the implementation can receive larger packets.

size—The default value is 1500 octets. If smaller packets are requested, an implementation still must be able to receive the full 1500 octet information field in case link synchronization is lost.

ppp iface lcp {local remote} default

Default—Issuing this command verbatim resets the lcp negotiation options to their default values, as specified by RFC1661. Default values are:
