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:
Interface Admin Link Proto Local Remote at-2/2/0 up up at-2/2/0.100 up up inet 10.10.10.1 --> 10.10.20.1 at-2/2/0.32767 up up
To display the status of a specific ATM MIC interface:

Output packets: 0
VCI 7.4
Flags: Active
Total down time: 0 sec, Last down: Never
Input packets : 0
Output packets: 0 Meaning
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 |
