SROS Command Line Interface Reference Guide Global Configuration Mode Command Set

interface ppp <label>

Use the interface ppp command to create a virtual point-to-point protocol (PPP) interface that is identified

using the entered number label. In addition, entering this command activates the PPP interface. Use the no

form of this command to delete a configured virtual PPP interface.

Syntax Description

<label> Specifies the numerical virtual PPP interface identifying label (valid range:

1 to 1024)

Default Values

By default, there are no configured PPP interfaces.

Command Modes

(config)# Global Configuration Mode required

Functional Notes

Creating an endpoint that uses a layer 2 protocol (such as PPP) is generally a four-step process:

Step 1:

Create the PPP virtual endpoint (using the interface ppp) command and enter the PPP.

(config)#interface ppp 7

(config-ppp 7)#

Step 2:

Configure the interface parameters to apply access policies to the interface, create bridging interfaces,

configure backup, and assign an IP address. For example, the following assigns an IP address of

193.44.69.1/30 to the interface.

(config-ppp 7)#ip address 193.44.69.1 255.255.255.252

Step 3: (VALID ONLY FOR T1 INTERFACES)

Specify the group of DS0s used for signaling on the T1 interface by creating a tdm-group. Group any

number of aggregate DS0s together to create a data pipe for layer 2 signaling. Also use the tdm-group

command to specify the per-DS0 signaling rate on the interface. For example, the following creates a

tdm-group labeled 9 containing 20 DS0s (each DS0 having a data rate of 56 kbps).

(config)#interface t1 1/1

(config-t1 1/1)#tdm-group 9 timeslots 1-20 speed 56

(config-t1 1/1)#exit
