Monitoring ATM MIC Interfaces
To monitor the status of ATM MIC interfaces, perform the following tasks:
Displaying the Status of a Specific ATM MIC Interface
Purpose
Display the status of a specific ATM MIC interface.
Action
To display the summary information about a specific ATM MIC interface:

The first line of the sample output shows that the physical link and all logical links are up. This means that the interface can pass packets.
Further down the sample output, look for active alarms and defects. If there are any, and to further diagnose the problem, see Displaying Extensive Information for a Specific ATM MIC Interface to display more extensive information about the ATM interface and the physical interface that is down.
Table 1 lists the show interfaces terse command output fields.
Table 1: show interfaces terse Output Fields
Field Name | Field Description |
|---|---|
Interface | Interface name. |
Admin | The administrative status of the interface. Possible values: up or down. |
Link | Status of the link. Possible values: up or down. |
Proto | Protocol family configured on the logical interface. |
Local | Local IP address of the logical interface. |

Meaning
The sample output is for an OC3 ATM interface and shows the statistics for the SONET media, as well as the Input and Output ATM errors. Error details include input and output errors, active alarms and defects, and media-specific errors.
If the physical link is down, look at the active alarms and defects for the ATM interface and check the ATM media accordingly. See List of Common ATM Alarms and Error for an explanation of ATM alarms.
For information about the output fields of the show interfaces extensive command, see show interfaces (ATM).
Monitoring Traffic and Error Statistics for an ATM MIC Interface
Purpose
Monitor traffic and error statistics for an ATM MIC interface.
Action
To display real-time statistics, updated every second, for an ATM MIC interface:
 | Caution: We recommend that you use this command only for diagnostic purposes. If you use this command during normal router operations, additional CPU and memory resources are consumed. |

Meaning
The sample output displays common interface failures and any increase in framing errors. Information from this command can help you narrow down possible causes of an interface problem.
 | Note: If you are accessing the router from the console connection, make sure you set the CLI terminal type using the set cli terminal command. |
