show interface XTagATM
To display information about an extended MPLS ATM interface, use the show interface XTagATM EXEC command.

Usage Guidelines
Extended MPLS ATM interfaces are virtual interfaces that are created on first reference like tunnel interfaces. Extended MPLS ATM interfaces are similar to ATM interfaces except that the former only supports LC-ATM encapsulation.
Examples
The following is sample output from the show interface XTagATM command:
Router# show interface XTagATM0
XTagATM0 is up, line protocol is up
Hardware is Tag-Controlled Switch Port
Interface is unnumbered. Using address of Loopback0 (12.0.0.17)
MTU 4470 bytes, BW 156250 Kbit, DLY 80 usec, rely 255/255, load 1/255
Encapsulation ATM Tagswitching, loopback not set
Encapsulation(s): AAL5
Control interface: ATM1/0, switch port: bpx 10.2
9 terminating VCs, 16 switch cross-connects
Switch port traffic:
129302 cells input, 127559 cells output
Last input 00:00:04, output never, output hang never
Last clearing of "show interface" counters never
Queueing strategy: fifo
Output queue 0/0, 0 drops; input queue 0/75, 0 drops
Terminating traffic:
5 minute input rate 1000 bits/sec, 1 packets/sec
5 minute output rate 0 bits/sec, 1 packets/sec
61643 packets input, 4571695 bytes, 0 no buffer
Received 0 broadcasts, 0 runts, 0 giants
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort

Usage Guidelines
Some of the content in the display of the show ip cache flow command uses multiline headings and multiline data fields. Figure 2 shows how to associate the headings with the correct data fields when there are two lines of headings and two lines of data fields. The first line of the headings is associated with the first line of data fields. The second line of the headings is associated with the second line of data fields.
When other features are configured, the number of lines in the headings and data fields increases. The method for associating the headings with the correct data fields remains the same.
