debug atm packet Command

Use the debug atm packet command to display all process-level ATM packets for both outbound and
inbound packets. The output reports information online when a packet is received or a transmission is
attempted. The no form of this command disables debugging output.
Because the debug atm packet command generates a significant amount of output for every packet
Caution
processed, use it only when network traffic is low, so that other system activities are not adversely
affected.
The command syntax is:
debug atm packet [interface atm number [vcd vcd-number][vc vpi/vci number]]
no debug atm packet [interface atm number [vcd vcd-number][vc vpi/vci number]]
where the keywords are defined as follows:
interface atm number
vcd vcd-number
vc vpi/vci number
