Con®guring Frame Relay Interfaces

 

pvc-groups

switched-virtual-circuits

all

Displays the Frame Relay con®guration. The display is a combination of the

 

list hdlc, the list lmi, and the list permanent virtual circuits commands.

See list hdlc and list lmi for descriptions of the parameters.

hdlc Displays the Frame Relay High-Level Data Link Control (HDLC) con®guration.

Example:

list hdlc

 

Frame Relay HDLC Configuration

Maximum frame size

= 2048

Encoding

= NRZ

Idle state

= Flag

Clocking

= External

Cable type

= V.35 DTE

Line speed (bps)

= 64000

Transmit delay

= 0

Lower DTR

= Enabled

Encoding

 

The transmission encoding scheme for the serial interface.

 

Encoding is NRZ (non-return to zero) or NRZI (non-return to zero

 

inverted).

Idle

The data link idle state: ¯ag or mark.

Clocking

 

The type of clocking: internal or external.

Cable type

 

The serial adapter cable type: RS-232, V.35, V.36, or X.21.

Line Speed (bps)

 

Indicates the physical data rate for the Frame Relay interface.

Maximum frame size

 

Indicates the maximum frame size that can be transmitted or

 

received over the network at any given time.

Transmit delay

Indicates the number of additional ¯ag bytes sent between frames.

Lower DTR

Indicates whether the router will drop 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. Lower DTR does not appear when the cable type is X.21.

Notes:

1.For a FR dial circuit interface, only the maximum frame size is displayed.

lmi Displays logical management and related con®guration information about the Frame Relay interface.

Example:

list lmi
