Command History

Release	Modification
12.0(3)T	This command was introduced.

Usage Guidelines

Extended-label ATM interfaces are virtual interfaces that are created on first reference like tunnel interfaces. They are similar to ATM interfaces except that they only support TC-ATM encapsulation.

Use the show interface XTagATM command to display information about an extended label ATM interface.

The following is sample output from the show interface XTagATM command:

Table 17: show interface XTagATM Field Descriptions

Field	Description
XTagATM0 is up	Interface is currently active.
line protocol is up	Shows line protocol is up.
Hardware is Label-Controlled Switch Port	Specifies the hardware type.
Interface is unnumbered	Specifies that this is an unnumbered interface.
MTU	Maximum transmission unit of the extended label ATM interface.
BW	Bandwidth of the interface in kilobits per second.
DLY	Delay of the interface in microseconds.
rely	Reliability of the interface as a fraction of 255 (255/255 is 100% reliability), calculated as an exponential average over 5 minutes.
load	Load on the interface as a fraction of 255 (255/255 is completely saturated), calculated as an exponential average over 5 minutes.
Encapsulation ATM Label switching	Encapsulation method.
loopback not set	Indicates that loopback is not set.
Encapsulation(s)	Identifies the ATM adaptation layer.
Control interface	Identifies the control port switch port with which the extended label ATM interface has been associated through the extended-port interface configuration command.
9 terminating VCs	Number of terminating VCs with an endpoint on this extended label ATM interface. Packets are transmitted and/or received by the LSC on a terminating VC, or are forwarded between an LSC-controlled switch port and a router interface.
16 switch cross-connects	Number of switch cross-connects on the external switch with an endpoint on the switch port that corresponds to this interface. This includes cross-connects to terminating VCs that carry data to and from the LSC, as well as cross-connects that bypass the LSC and switch cells directly to other ports.
Switch port traffic:	Number of cells received and transmitted on all cross-connects associated with this interface.
Terminating traffic counts:	Indicates that counters below this line apply only to packets transmitted or received on terminating VCs.
Five minute input rate, Five minute output rate	Average number of bits and packets transmitted per second in the last 5 minutes.
packets input	Total number of error-free packets received by the system.
bytes	Total number of bytes, including data and MAC encapsulation, in the error-free packets received by the system.
no buffer	Number of received packets discarded because there was no buffer space in the main system. Compare with ignored count. Broadcast storms on Ethernets and bursts on noise on serial lines are often responsible for "no input buffer" events.
broadcasts	Total number of broadcast or multicast packets received by the interface.
runts	Number of packets that are discarded because they are smaller than the minimum packet size for the medium.
giants	Number of packets that are discarded because they exceed the maximum packet size for the medium.
input errors	Total number of no buffer, runts, giants, CRCs, frame, overrun, ignored, and abort counts. Other input-related errors can also increment the count, so that this sum may not balance with the other counts.
CRC	Cyclic redundancy checksum generated by the originating LAN station or far end device does not match the checksum calculated from the data received. On a LAN, this usually indicates noise or transmission problems on the LAN interface or the LAN bus itself. A high number of CRCs is usually the result of collisions or a station transmitting bad data. On a serial link, CRCs usually indicate noise, gain hits, or other transmission problems on the data link.
frame	Number of packets received incorrectly having a CRC error and a noninteger number of octets.
overrun	Number of times the serial receiver hardware was unable to hand received data to a hardware buffer because the input rate exceeded the ability of the receiver to handle the data.
ignored	Number of received packets ignored by the interface because the interface hardware ran low on internal buffers. These buffers are different from the system buffers mentioned previously in the buffer description. Broadcast storms and bursts of noise can cause the "ignored" count to be incremented.
abort	Illegal sequence of one bits on the interface. This usually indicates a clocking problem between the interface and the data link equipment.
packets output	Total number of messages transmitted by the system.
bytes	Total number of bytes, including data and MAC encapsulation, transmitted by the system.
underruns	Number of times that the transmitter has been running faster than the router can handle. This may never be reported on some interfaces.
output errors	Sum of all errors that prevented the final transmission of datagrams out of the interface being examined. Note that this may not balance with the sum of the enumerated output errors, as some datagrams may have more than one error, and others may have errors that do not fall into any of the specifically tabulated categories.
collisions	Number of messages retransmitted due to an Ethernet collision. This is usually the result of an overextended LAN (Ethernet or transceiver cable too long, more than two repeaters between stations, or too many cascaded multiport transceivers). A packet that collides is counted only once in output packets.
interface resets	Number of times an interface has been completely reset. This can happen if packets queued for transmission were not sent within several seconds. On a serial line, this can be caused by a malfunctioning modem that is not supplying the transmit clock signal, or by a cable problem. If the system notices that the carrier detect line of a serial interface is up, but the line protocol is down, it periodically resets the interface in an effort to restart it. Interface resets can also occur when an interface is looped back or shut down.
output buffers copied	Number of packets copied from a MEMD buffer into a system buffer before being placed on the output hold queue.
interrupts	Displays the value of hwidb to tx_restarts.
failures	Number of packets discarded because no MEMD buffer was available.
