Cisco IOS SoftwareConfiguration for theCisco 12000 SeriesOne-Port Channelized OC-12/STM-4(DS1/E1) ISE Line

How to Configure Layer 1 Features

Cisco IOS Release 12.0(27)S1

Removing a Logical Channel Group from a T1 Line

You can remove a logical channel group from a T1 line (or a T1 line) with the no form of the t1

t1-line-number channel-group channel-group-number STS-1 path configuration command, using the

extended command prefix that is appropriate to your channelized configuration.

To configure a T1 line, you must enter controller configuration mode and specify the line card slot and

port. The following examples show a SONET controller in slot 6 and port 0.

• The following example shows the process of removing a logical channel group in vt15 mode:

Router(config)# controller sonet 6/0

Router(config-controller)# sts-1 1

Router(config-ctrlr-sts1)# no vtg 1 t1 1 channel-group 15 timeslots 1-5, 20-23

Router(config-ctrlr-sts1)#

• The following example shows the process of removing a logical channel group in ct3 mode, which

means that no extended command prefix is required:

Router(config)# controller sonet 6/0

Router(config-controller)# sts-1 1

Router(config-ctrlr-sts1)# no t1 1 channel-group 15 timeslots 1-5, 20-23

Router(config-ctrlr-sts1)#

Using the ping Command to Verify Network Connectivity

Using the ping command, you can verify that an interface port is functioning properly. The ping

command sends echo request packets out to a remote device at an IP address that you specify. After

sending an echo request, the system waits a specified time for the remote device to reply. Each echo reply

is displayed as an exclamation point (!) on the console terminal; each request that is not returned before

the specified timeout is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good

connection; a series of periods (.....) or the messages [timed out] or [failed] indicate a bad connection.

Following is an example of a successful ping command to a remote server with the address 10.0.0.10:

Router# ping 10.0.0.10

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echoes to 10.0.0.10, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms

Router#

If the connection fails, verify that you have the correct IP address for the destination and that the device

is active (powered on), then repeat the ping command.

Proceed to the next section, “Using T1 Interface Loopback Modes,” to finish checking network

connectivity.

Using T1 Interface Loopback Modes

If you have difficulty with the 1-Port CHOC-12 ISE line card configuration or installation, you can

troubleshoot the problem using the t1 t1-line-number loopback [local | network {line | payload} |

remote {line fdl {ansi | bellcore} | payload [fdl] [ansi]}] path configuration command, using the

1 2 ... 13 14 15 16 17 18 19 20 21 22 23 ... 57 58
