Table 16 describes the fields shown in the display.
| 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, or 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 |
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 the elapsed time is too large to be displayed. |
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 | 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, | 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. |

VC-class configuration (for a VC class)
This command first appeared in Cisco IOS Release 11.3 T.
To configure ATM SVCs with an output peak cell rate and an input peak cell rate that differ from each other, you must expressly configure an output value and an input value using the output-pcr and input-pcr arguments, respectively.
Configure QOS parameters using the ubr, ubr+ or vbr-nrt command. The last command you enter will apply to the PVC or SVC you are configuring.
If the ubr command is not explicitly configured on an ATM PVC or SVC, the VC inherits the following default configuration (listed in order of next highest precedence):
The following example specifies the output-pcr for an ATM PVC to be 100,000 Kbps:

To select Unspecified Bit Rate (UBR) QOS and configure the output peak cell rate and output minimum guaranteed cell rate for an ATM PVC, SVC, or VC class, use the ubr+ command in the appropriate command mode. Use the no form of this command to remove the UBR+ parameters.
ubr+ output-pcr output-mcr [input-pcr] [input-mcr]
output-pcr | The output peak cell rate in kilobits per second. |
output-mcr | The output minimum guaranteed cell rate in kilobits per second. |
input-pcr | (Optional for SVCs only) The input peak cell rate in kilobits per second. If this value is omitted, the input-pcr will equal the output-pcr. |
input-mcr | (Optional for SVCs only) The input minimum guaranteed cell rate in kilobits per second. If this value is omitted, the input-mcr will equal the output-mcr. |
UBR QOS at the maximum line rate of the physical interface.

VC-class configuration (for a VC class)
This command first appeared in Cisco IOS Release 11.3 T.
To configure ATM SVCs with an output rate and input rates that differ from each other, you must expressly configure output values and input values using the output-pcr, output-mcr, input-pcr, and input-mcr, arguments, respectively.
Configure QOS parameters using the ubr, ubr+ or vbr-nrt command. The last command you enter will apply to the PVC or SVC you are configuring.
If the ubr+ command is not explicitly configured on an ATM PVC or SVC, the VC inherits the following default configuration (listed in order of next highest precedence):
The following example specifies the output-pcr to be 100,000 Kbps and the output-mcr to be 3000 Kbps for an ATM PVC:
pvc 1/32 ubr+ 100000 3000
The following example specifies the output-pcr, output-mcr, input-pcr, and input-mcr for an ATM SVC to be 10,000 Kbps, 3000 Kbps, 9000 Kbps, and 1000 Kbps, respectively:
svc lion nsap 47.0091.81.000000.0040.0B0A.2501.ABC1.3333.3333.05 ubr+ 10000 3000 9000 1000

To configure the Variable Bit Rate-Non Real Time (VBR-NRT) QOS and specify output peak cell rate, output sustainable cell rate, and output maximum burst cell size for an ATM PVC, SVC, or VC class, use the vbr-nrt command in the appropriate command mode. Use the no form of this command to remove the VBR-NRT parameters.
vbr-nrt output-pcr output-scr output-mbs [input-pcr] [input-scr] [input-mbs]
output-pcr | The output peak cell rate in kilobits per second. |
output-scr | The output sustainable cell rate in kilobits per second. |
output-mbs | The output maximum burst cell size expressed in number of cells. |
input-pcr | (Optional for SVCs only) The input peak cell rate in kilobits per second. |
input-scr | (Optional for SVCs only) The input sustainable cell rate in kilobits per second. |
input-mbs | (Optional for SVCs only) The input maximum burst cell size expressed in number of cells. |

Interface-ATM-VC configuration (for an ATM PVC or SVC)
VC-class configuration (for a VC class)
This command first appeared in Cisco IOS Release 11.3 T.
Configure QOS parameters using the ubr, ubr+ or vbr-nrt command. The last command you enter will apply to the PVC or SVC you are configuring.
If the vbr-nrt command is not explicitly configured on an ATM PVC or SVC, the VC inherits the following default configuration (listed in order of next highest precedence):
The following example specifies the output-pcr to be 100,000 Kbps, the output-scr to be 50,000 Kbps, and the output-mbs to be 64:
pvc 1/32 vbr-nrt 100000 50000 64
The following example specifies the VBR-NRT output and input parameters for an ATM SVC:
svc lion nsap 47.0091.81.000000.0040.0B0A.2501.ABC1.3333.3333.05 vbr-nrt 10000 5000 32 20000 10000 64

peak-rate | The Peak Information Rate (PIR) of the voice connection in Kbps. The range is from 56 to 10,000. |
average-rate | The Average Information Rate (AIR) of the voice connection in Kbps. The range is from 1 to 56. |
burst | Burst size in number of cells. The range is from 0 to 65536. |
No vbr-rt settings are configured.
ATM Virtual Circuit configuration
This command first appeared in Cisco IOS Release 12.0.
This command applies to Voice over ATM on the Cisco MC3810.
The vbr-rt command configures traffic shaping between voice and data PVCs. Traffic shaping is required so that the carrier does not discard calls. To configure voice and data traffic shaping, you must configure the peak, average, and burst options for voice traffic. Configure the burst value if the PVC will be carrying bursty traffic. The peak, average, and burst values are needed so the PVC can effectively handle the bandwidth for the number of voice calls. To calculate the minimum peak, average, and burst values for the number of voice calls, use the following calculations:
The following example configures the traffic shaping rate for ATM PVC 20 on a Cisco MC3810. In the example, the peak, average and burst rates are calculated based on a maximum of 20 calls on the PVC.

To create a VC class for an ATM PVC, SVC, or ATM interface and enter vc-class configuration mode, use the vc-class atm global configuration command. Use the no form of this command to remove a VC class.
vc-class atm name
name | Name of your VC class. |
No VC class is defined.
Global configuration
This command first appeared in Cisco IOS Release 11.3 T.
You can configure the following commands in a VC class:
If an SVC command (for example, the idle-timeout or oam-svc command) is applied on a PVC, the command is ignored. This is also true if a PVC command is applied to an SVC.
The following example creates a VC class named pvc-qos:
