show atm vc
MP-427
Cisco IOS Multiprotocol Label Switching Command Reference
January 2010
VCs on the extended MPLS ATM interfaces do not appear in the show atm vc command output. Instead,
the show xtagatm vc command provides a similar output that shows information only on extended
MPLS ATM VCs.
Examples The following is sample output from the show atm vc command when no vcd value is specified. The
status field is either ACTIVE or INACTIVE.
Router# show atm vc
Interface VCD VPI VCI Type AAL/Encaps Peak Avg. Burst Status
ATM2/0 1 0 5 PVC AAL5-SAAL 155000 155000 93 ACTIVE

The following is sample output from the show atm vc command when a vcd value is specified for a
circuit emulation service (CES) circuit:
Router# show atm vc 2
ATM6/0: VCD: 2, VPI: 10, VCI: 10
PeakRate: 2310, Average Rate: 2310, Burst Cells: 94
CES-AAL1, etype:0x0, Flags: 0x20138, VCmode: 0x0

The following is sample output from the show atm vc command when a vcd value is specified,
displaying statistics for that virtual circuit only:
Router# show atm vc 8
ATM4/0: VCD: 8, VPI: 8, VCI: 8
PeakRate: 155000, Average Rate: 155000, Burst Cells: 0

The following is sample output from the show atm vc command when a vcd value is specified, AAL3/4
is enabled, an ATM Switched Multimegabit Data Service (SMDS) subinterface has been defined, and a
range of message identifier numbers (MIDs) has been assigned to the PVC:
Router# show atm vc 1
ATM4/0.1: VCD: 1, VPI: 0, VCI: 1
PeakRate: 0, Average Rate: 0, Burst Cells: 0
AAL3/4-SMDS, etype:0x1, Flags: 0x35, VCmode: 0xE200
MID start: 1, MID end: 16
InPkts: 0, OutPkts: 0, InBytes: 0, OutBytes: 0
