Monitor Channelized OC12 Interfaces
Purpose
By monitoring Channelized OC12 interfaces, you begin the process of isolating Channelized OC12 interface problems when they occur.
To monitor your Channelized OC12 interfaces, follow these steps:
Display the Status of Channelized OC12 Interfaces
Purpose
To display the status of Channelized OC12 interfaces, use the following Junos OS command-line interface (CLI) operational mode command:
Action
Sample Output 1
The following sample output is for a Channelized OC12 interface:
user@host> show interfaces terse t3-0/3/0:* Interface Admin Link Proto Local Remote t3-0/3/0:0 up up t3-0/3/0:1 up up t3-0/3/0:2 up up t3-0/3/0:3 up up t3-0/3/0:4 up up t3-0/3/0:5 up up t3-0/3/0:6 up up t3-0/3/0:7 up up t3-0/3/0:8 up up t3-0/3/0:9 up up t3-0/3/0:10 up up t3-0/3/0:11 up down
Meaning
The sample output shows the status of both the physical and logical interfaces. In this example, all of the Channelized OC12 interfaces are up except the channel interface t3-0/3/0:11.
When only one or some individual T3 channels are down, you must troubleshoot the T3 channel by checking the configuration, transmission network, and equipment. If all of the physical layers for the T3 channels are down, you must work with this as a T3 or OC12 SONET link, or a Physical Interface Card (PIC) problem. For more information on monitoring SONET interfaces, see Checklist for Monitoring Channelized OC12 Interfaces.
Display the Status of a Specific Channelized OC12 Interface
Purpose
To display the status of specific Channelized OC12 interface, use the following Junos OS CLI operational mode command:
Action
Sample Output
user@host> show interfaces terse t3-0/3/0:0
Interface Admin Link Proto Local Remote t3-0/3/0:0 up up user@host> show interfaces terse t3-0/3/0:11 Interface Admin Link Proto Local Remote t3-0/3/0:11 up down
Meaning
The first line of the output shows the status of the link. If this line shows that the physical link is up, the physical link is healthy and can pass packets. If this line shows that the physical link is down, the physical link is unhealthy and cannot pass packets.
When only one or some individual T3 channels are down, you must troubleshoot the T3 channel by checking the configuration, transmission network, and equipment. If all of the physical layers for the T3 channels are down, you must work with this as an OC12 SONET link or PIC problem. For more information on monitoring SONET interfaces, see Checklist for Monitoring Channelized OC12 Interfaces.

Monitor Statistics for a Channelized OC12 Interface
Purpose
To monitor statistics for a Channelized OC12 interface, use the following Junos OS CLI operational mode command:
Action
Sample Output
user@host> monitor interfaces t3-0/3/0:11 host Seconds: 12 Time: 17:27:15
Delay: 32/0/32

Error statistics:
Input errors: 0 [0]
Input drops: 0 [0]
Input framing errors: 1066 [0]
Input runts: 0 [0]
Input giants: 0 [0]
Policed discards: 0 [0]
L3 incompletes: 0 [0]
L2 channel errors: 3 [0]
L2 mismatch timeouts: 0 [0]
Carrier transitions: 7 [0]
Output errors: 0 Output drops: [0]
Interface warnings:
o Loopback detected while not in test mode
Meaning
The sample output shows common interface failures, indicates whether loopback is detected, and shows increases in framing errors. Use information from this command to help narrow down possible causes of an interface problem.
If you are accessing the router from the console connection, make sure you set the CLI terminal type using the set cli terminal command.
We recommend that you use this command only for diagnostic purposes. Do not leave it on during normal router operations because real-time monitoring of traffic consumes additional CPU and memory resources.

Meaning
The sample output shows the status of both the physical and logical interfaces. In this example, all of the channelized OC12 IQ interfaces are up.
Sample output 1 shows the channelized interfaces that are configured, but not the channels for those channelized interfaces.
Sample output 2 shows the channels for the channelized interfaces that are configured and the hierarchy, but not the interface address information. At the top, the hierarchy includes the controller interface coc12-0/0/0.
Sample output 3 shows all channelized interfaces and their configured channels and the address information.
When only one or some individual channels are down, you must troubleshoot the channel by checking the configuration, transmission network, and equipment. If all of the physical layers for the channels are down, you must work with this as a T1, T3, DS0, or OC12 SONET link or PIC problem. For more information on monitoring these types of interfaces, see the respective sections in this guide.
The interface configuration of the OC12 IQ interface used for all show commands in this section is shown in Figure 1.
In addition, the configuration is shown in the following output:
The above configuration shows the OC12 IQ interface configured into eight channels or slices as shown in Figure 1. A summary of the channels follows:
Channels 1 through 3 are for SONET interfaces
Channel 4 is for T1 interfaces
Channel 5 is for T3 interfaces
Channel 6 is for DS0 interfaces
Channels 7 is for T1 interfaces
Channel 8 is for DS0 interfaces
Display the Status of the Controller Channelized OC12 IQ Interface
Purpose
To display the status of the controller OC12 IQ interface, use one or all of the following Junos OS CLI operational mode commands, depending on the level of channelization:
Action

Meaning
The first line of the output shows the status of the link. If this line shows that the physical link is up, the physical link is healthy and can pass packets. If this line shows that the physical link is down, the physical link is unhealthy and cannot pass packets.
The controller interface is partitioned into other interface types and appears at the top of a specific level of channelization. For a visual representation of the controller interface at different levels of channelization, see Figure 2.
Each of the four examples of controller output is for a different level of channelization.
Sample output 1 for interface coc12-0/0/0 shows Parent: None, which indicates the top-most level of channelization.
Sample output 2 for interface coc1-0/0/0:2 shows Parent: coc12-0/0/0,which indicates that this interface is one level down from the top-most level, and is the OC1 controller for a first level of channelization.
Sample output 3 for interface ct3-0/0/0:5 shows Parent: coc1-0/0/0:5, which indicates that this interface is at the second level of channelization, and is a CT3 controller.
Sample output 4 for interface ct1-0/0/0:4:1 shows Parent: coc1-0/0/0:4:1,which indicates that this interface is at the third level of channelization, and is a CT1 controller.

Meaning
The first line of the output shows the status of the link. If this line shows that the physical link is up, the physical link is healthy and can pass packets. If this line shows that the physical link is down, the physical link is unhealthy and cannot pass packets. All four examples of output show the link is up and can pass packets.
Sample output 1 shows an OC3 SONET interface. Sample output 2 shows a T1 interface that is the result of a partitioned OC1 interface, and sample output 3 shows a DS0 interface that is the result of an OC1 interface partitioned into a T1 interface, which is further partitioned into the DS0 interface.
Figure 3 shows a visual representation of the different channel levels.
When only one or some individual channels are down, you must troubleshoot the channel by checking the configuration, transmission network, and equipment. If all of the physical layers for the channels are down, you must work with this as a T1, T3, DS0, or OC12 SONET link or PIC problem. For more information on monitoring these types of interfaces, see the respective sections in this guide.

Meaning
The sample output shows where the errors might be occurring: either with the channel media or the SONET layer. In this example, there are no errors. However, if errors occur, you must troubleshoot the channel media or the SONET layer. For more information, see the sections of this guide that correspond to the media with which you are working.

Meaning
The sample output shows common interface failures, indicates whether loopback is detected, and shows increases in framing errors. Use information from this command to help narrow down possible causes of an interface problem.
If you are accessing the router from the console connection, make sure you set the CLI terminal type using the set cli terminal command.
We recommend that you use this command only for diagnostic purposes. Do not leave it on during normal router operations because real-time monitoring of traffic consumes additional CPU and memory resources.
