Configuration Examples

This section provides some configuration examples to illustrate how to use the CLI commands.

Example 1: Configuring Interfaces in SONET Mode

The following example illustrates how to configure T1 lines on channelized SONET interfaces, as shown in Figure 11.

Figure 11: Configuring Fractional T1 in SONET Mode

1. Select an OC-12 SONET controller.

   host1(config)#controller sonet 4/0

2. Configure two STS-1 paths.

   host1(config-controller)#path 2 oc1 1/2

   host1(config-controller)#path 10 oc1 4/1

3. Configure two VT1.5 tributaries on SONET path channel 2.

   host1(config-controller)#path 2 ds1 1/2/2 vt15

   host1(config-controller)#path 2 ds1 1/7/4 vt15

4. Configure two fractional T1 lines on VT 1/2/2 in path 2.

   host1(config-controller)#path 2 ds1 1/2/2 channel-group 1 timeslots 1-10

   host1(config-controller)#path 2 ds1 1/2/2 channel-group 2 timeslots 11, 21-26

5. Configure a fractional T1 line on VT 1/7/4 in path 2.

   host1(config-controller)#path 2 ds1 1/7/4 channel-group 1 timeslots 2-7

6. Configure an unchannelized T3 on SONET path channel 10.

   host1(config-controller)#path 10 ds3 1 unchannelized

7. Configure a channelized T3 on SONET path channel 12.

   host1(config-controller)#path 12 ds3 1 channelized

8. Configure a T1 channel on the channelized T3 on SONET path channel 12.

   host1(config-controller)#path 12 ds3 1 t1 4

9. Configure two fractional T1 lines on the T3 in path channel 12.

   host1(config-controller)#path 12 ds3 1 t1 4/1 timeslots 3-8

   host1(config-controller)#path 12 ds3 1 t1 4/2 timeslots 20

Example 2: Configuring Interfaces in SDH Mode

The following example illustrates how to configure fractional E1 and unframed E1 lines in SDH mode, as shown in Figure 12.

Figure 12: Configuring Fractional E1 and Unframed E1 in SDH Mode

1. Select an OC-12 SONET controller.

   host1(config)#controller sonet 4/0

2. Switch to SDH mode.

   host1(config-controller)#sdh

3. Configure four STM-1 paths. An OC-12 interface has four STM-1 paths.

   host1(config-controller)#path 10 stm1 1

   host1(config-controller)#path 20 stm1 2

   host1(config-controller)#path 30 stm1 3

   host1(config-controller)#path 40 stm1 4

4. Configure a TU-12 on TUG-2 #7 on TUG-3 #2 of path 10.

   host1(config-controller)#path 10 e1 2/7/1 tu12

5. Configure a TU-12 on TUG-2 #5 on TUG-3 #2 of path 10.

   host1(config-controller)#path 10 e1 2/5/2 tu12

6. Configure a fractional E1 line on tributary 2/7/1 of path 10.

   host1(config-controller)#path 10 e1 2/7/1 channel-group 1 timeslots 2-5

7. Configure an unframed E1 line on tributary 2/5/2 of path 10.

   host1(config-controller)#path 10 e1 2/5/2 unframed

8. Configure a TU-12 on TUG-2 #4 on TUG-3 #1 of path 30.

   host1(config-controller)#path 30 e1 1/4/1 tu12

9. Configure an unframed E1 line on tributary 1/4/1 of path 30.

   host1(config-controller)#path 30 e1 1/4/1 unframed

Example 3: Configuring Frame Relay

The following example illustrates how to configure Frame Relay on VT 1/7/4 in path 2 of the configuration shown in Figure 11.

1. Select the interface on which you want to configure Frame Relay.

   host1(config)#interface serial 4/0:2/1/7/4/1

2. Specify Frame Relay as the encapsulation method on the interface.

   host1(config-if)#encapsulation frame-relay ietf

3. Configure the interface as a DTE, DCE, or NNI.

   host1(config-if)#frame-relay intf-type dce

Example 4: Configuring PPP

The following example illustrates how to configure PPP on VT 1/2/2 in path 2 of the configuration shown in Figure 11.

1. Select the interface on which you want to configure PPP.

   host1(config)#interface serial 4/0:2/1/2/2/1

2. Specify PPP as the encapsulation method on the interface.

   host1(config-if)#encapsulation ppp
