Con®guring PPP Interfaces (Talk 6)

ecp Displays the current Encryption Control Protocol state.

Example:

list ecp ECP Options

-----------

Data Encryption enabled Algorithm list: DESE-CBC

DESE (Data Encryption Standard Encryption Protocol)

Data Encryption Enabled/Disabled

Indicates whether data encryption is enabled or disabled on interface.

Algorithm List

Displays the supported encryption algorithms. DES, as described by RFC 1969, is the only encryption algorithm currently supported.

hdlc Lists parameters related to the High-Level Data Link Control (HDLC) protocol. On PPP dial circuit interfaces, the ªlist hdlcº option is not available. For dial circuits, hardware data link parameters are a function of the base net rather than the PPP dial circuit. For additional information, see ªChapter 47. Con®guring and Monitoring Dial Circuitsº on page 643.

Example:

list hdlc Encoding: NRZ Idle State: Flag Clocking: Internal Cable type: V.35 DCE Speed (bps): 6400

Transmit Delay Counter: 0

Lower DTR: Disabled

Encoding:

HDLC transmission encoding scheme, either NRZ (non-return to zero) or NRZI (non-return to zero inverted).

Idle State:

Bit pattern, either Flag or Mark, transmitted on the point-to-point link when the interface is not transmitting data.

Clocking:

Interface clocking, either external or internal.

Cable type:

Speci®es the type of cable in use (RS-232, V.35, or V.36).

Speed (bps):

The physical data rate of the interface. When clocking is internal, this is the data rate generated by the internal clock.

Transmit Delay Counter:

Number of ¯ags sent between frames.

Lower DTR:

Enabled or Disabled. If Lower DTR is enabled, the router drops the DTR signal when a WAN Reroute alternate link is no longer needed. Dropping the DTR signal causes the modem to terminate the leased-line connection for the alternate link.

Notes:

1.The list hdlc command is not supported on PPP dial circuit interfaces.

2.This command displays the Lower DTR state only if Lower DTR is supported for the con®gured cable type.
