Troubleshooting 25-Mbps Interfaces
Note Errors and the input and output difference should not exceed 0.5 to 2.0 percent of traffic on
the interface.
If you determine that the physical interface is configured incorrectly, refer to the “Configuring
Interfaces” chapter in the ATM Switch Router Software Configuration Guide.
Follow these steps to show how to troubleshoot the configuration of a 25-Mbps interface:
Step 1 Use the show atm interface atm card/subcard/port command to check the configuration.
Switch# show atm interface atm 1/0/0
Interface: ATM1/0/0 Port-type: ATM25

Step 2 Check the IF Status and Admin Status fields to see whether they are up.
If down, check for the following:
• Disconnected or faulty cabling—Check cables.
• Hardware failure—Swap hardware.
If administratively down, the interface has been administratively taken down. Use the no shutdown
interface configuration command to reenable the interface.
