Syntax
debugging atm packet [ interface interface-type interface-number [ pvc { pvc-name [ vpi/vci ] |

vpi/vci } ] ]
Default

Default command level
1: Monitor level
Parameters
interface-type interface-number: Specifies an interface by its type and number.
pvc-name: PVC name, a string of 1 to 16 characters. A PVC name is unique on an ATM interface and is
not case-sensitive. It cannot be a valid VPI/VCI pair (such as 1/20).
vpi/vci: ATM virtual path identifier (VPI) and ATM virtual channel identifier (VCI). The vpi argument
ranges from 0 to 255. The range of the vci argument varies with interface types, as listed in Table 47.
Normally, VCI 0 through VCI 31 are reserved for special purposes.
Usage guidelines
If no interface is specified, the operation applies to all ATM interfaces.
If you do not specify the PVC name or VPI/VCI pair, the operation applies to all PVCs.
After debugging for ATM packets is enabled, large amount of output information is generated when the
device sends or receives a packet. Debugging for ATM packets might also disable users from managing
network devices through terminals and might greatly decrease forwarding performance.
Ta b l e 51 describes output fields and messages for the debugging atm packet command.
