Table 16 show dxi map Field Descriptions
Field
Description
DFA
Data Exchange Interface (DXI) Frame Address, similar to a data-link connection identifier (DLCI) for Frame Relay. The DFA is shown in decimal, hexadecimal, and DXI header format. The router computes this address value from the virtual path identifier (VPI) and virtual channel identifier (VCI) values.
encapsulation
Encapsulation type selected by the
dxipvc command. Displayed values can be
SNAP ,
NLPID , or
VC based MUX .
Linktype
Value used only with MUX encapsulation and therefore with only a single network protocol defined for the permanent virtual circuit (PVC). Maps configured on a PVC with MUX encapsulation must have the same link type.

Table 18 show interface cbr Field Descriptions
Field
Description
CBR6/0 is...
Type, slot, and port number of the interface and indicates whether the interface hardware is currently active (whether carrier detect is present), down, or if it has been taken down by an administrator.
line protocol is...
Indicates whether the software processes that handle the line protocol think the line is usable (that is, whether keepalives are successful). Values are up, down, and administratively down.
Hardware is...
Hardware type.
MTU
Maximum transmission unit of the 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. The calculation uses the value from the
bandwidth interface configuration command.
Encapsulation
Encapsulation method assigned to interface.
loopback not set
Indicates whether or not loopback is set.
Last input
Number of hours, minutes, and seconds since the last packet was successfully received by an interface. Useful for knowing when a dead interface failed.
Last output
Number of hours, minutes, and seconds since the last packet was successfully transmitted by an interface.
output hang
Number of hours, minutes, and seconds (or never) since the interface was last reset because of a transmission that took too long. When the number of hours in any of the "last" fields exceeds 24 hours, the number of days and hours is printed. If that field overflows, asterisks are printed.
Last clearing
The time at which the counters that measure cumulative statistics (such as number of bytes transmitted and received) shown in this report were last reset to zero. Note that variables that might affect routing (for example, load and reliability) are not cleared when the counters are cleared.
*** indicates that the elapsed time is too large to be displayed. 0:00:00 indicates that the counters were cleared more than 231ms (and less than 232ms) ago.
Queueing strategy
First-in, first-out queuing strategy (other queueing strategies you might see are priority-list, custom-list, and weighted fair).
Output queue, drops input queue, drops
Number of packets in output and input queues. Each number is followed by a slash, the maximum size of the queue, and the number of packets dropped due to a full queue.
5 minute input rate, 5 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 input
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 of 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 medium’s minimum packet size.
giants
Number of packets that are discarded because they exceed the medium’s maximum packet size.
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 receiver’s ability 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 than 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
Because collisions do not occur on CBR interfaces, this statistic is always zero.
interface resets
Number of times an interface has been reset. The interface may be reset by the administrator or automatically when an internal error occurs.
output buffer failures
Number of no resource errors received on the output.
output buffers swapped out
Number of packets swapped to DRAM.

The table below describes the fields shown in the sample displays.
Table 19 show interfaces atm Field Descriptions
Field
Description
ATM... is {up | down | administratively down}
Indicates whether the interface hardware is currently active (whether carrier detect is present) and if it has been taken down by an administrator.
line protocol is {up | down | administratively down}
Indicates whether the line is usable in the software processes that handle the line protocol (that is, whether keepalives are successful).
Hardware is
Hardware type.
Internet address is
Internet address and subnet mask.
MTU
Maximum transmission unit of the interface.
sub MTU
Maximum transmission unit of the subinterface.
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-percent 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. The calculation uses the value from the
bandwidth interface configuration command.
ATM E164 Auto Conversion Interface
Indicates that ATM E164 auto conversion is enabled. When this field is not present, ATM E164 auto conversion is disabled.
Encapsulation
Encapsulation method assigned to interface.
loopback
Indicates whether the interface is configured for loopback testing.
keepalive
Indicates whether keepalives are set.
Auto VC PADI
PPPoE Active Discovery Initiation (PADI) discard errors are displayed as part of overrun section of the show interface command output; here, overrun is the sum of oversubscription counters and PADI discard errors.
Encapsulation(s)
Type of encapsulation used on the interface (for example, ATM Adaptation Layer 5 (AAL5,) and either permanent virtual circuit (PVC) or switched virtual circuits (SVC) mode.
TX buffers
Number of buffers configured with the
atmtxbuff command.
RX buffers
Number of buffers configured with the
atmrxbuff command.
Maximum active VCs
Maximum number of virtual circuits.
VCs per VP
Number of virtual circuits per virtual path. The default is 1024.
Current VCs
Number of virtual circuit connections currently open.
VC idle disconnect time
Number of seconds the SVC must be idle before the SVC is disconnected.
Signalling vc
Number of the signaling PVC.
vpi
Virtual path identifier number.
vci
Virtual channel identifier number.
ATM NSAP address
Network Service Access Point (NSAP) address of the ATM interface.
Last input
Number of hours, minutes, and seconds since the last packet was successfully received by an interface. Useful for knowing when a dead interface failed.
Last output
Number of hours, minutes, and seconds since the last packet was successfully transmitted by an interface.
output hang
Number of hours, minutes, and seconds (or never) since the interface was last reset because of a transmission that took too long. When the number of hours in any of the “last” fields exceeds 24 hours, the number of days and hours is printed. If that field overflows, asterisks are printed.
Last clearing
The time at which the counters that measure cumulative statistics (such as number of bytes transmitted and received) shown in this report were last reset to zero. Note that variables that might affect routing (for example, load and reliability) are not cleared when the counters are cleared.
*** indicates that the elapsed time is too large to be displayed. 0:00:00 indicates that the counters were cleared more than 231 ms (and less than 232 ms) ago.
Queueing strategy
First-in, first-out queueing strategy (other queueing strategies you might see are priority-list, custom-list, and weighted fair).
Output queue, drops input queue, drops
Number of packets in output and input queues. Each number is followed by a slash, the maximum size of the queue, and the number of packets dropped due to a full queue.
5 minute input rate, 5 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 input
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 of noise on serial lines are often responsible for no input buffer events.
Received 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 medium’s minimum packet size.
giants
Number of packets that are discarded because they exceed the medium’s maximum packet size.
input errors
Total number of no buffer, runts, giants, CRCs, frame, overrun, ignored, oversubscription, and abort counts. Other input-related errors can also increment the count, so that this sum may not balance with the other counts.
Note
On a Cisco ASR 1000 Series Aggregation Services Router, the input errors field also includes the number of oversubscription drop packets, autodiscovery drops, and unknown packets received in the ingress direction. The ingress over subdrops counter accounts for packets dropped when the ATM ports experience heavy line traffic.
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 receiver’s ability to handle the data.
It also includes the oversubscription drop counters.
Note
On a Cisco ASR 1000 Series Aggregation Services Router, the overrun field includes the number of oversubscription drop packets, autodiscovery drops, and unknown packets received in the ingress direction that are collected from the ATM shared port adapters (SPA) hardware.
ignored
Number of received packets ignored by the interface because the interface hardware ran low on internal buffers. These buffers are different than 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
This feature is not applicable for ATM interfaces.
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 buffer failures
Number of times that a packet was not output from the output hold queue because of a shortage of MEMD shared memory.
output buffers swapped out
Number of packets stored in main memory when the output queue is full; swapping buffers to main memory prevents packets from being dropped when output is congested. The number is high when traffic is bursty.
restarts
Number of times the controller was restarted because of errors.
