Configuring the Cisco NM-1A-T3/E3 Network Module

  debug atm t3e3

25

Cisco IOS Release 12.4(15)T

Table 5

 describes the significant fields shown in the display.

The second example illustrates the output from the 

debug atm t3e3 trace

 command run in conjunction 

with the 

debug atm t3e3 sar

 command.

In this example, each command sent to the SAR is  displayed by the 

debug atm t3e3 sar

 command. Then 

the hexadecimal representation of the command and its acknowledgement are displayed by the 

debug 

atm t3e3 trace

 command.
