Table 69 describes the significant fields shown in the display.

Table 69 show interfaces content-engine Field Descriptions

Field

Description

Content-Engine

Indicates whether the CE interface hardware is currently active. If the CE interface hardware is operational, the output states that "Content-Engine slot/port is up." If it has been taken down by an administrator, the output states that "Content-Engine slot/port is administratively down."

line protocol

Indicates whether the software processes that handle the line protocol consider the line usable or whether the line has been taken down by an administrator.

Hardware...address

Hardware type and address.

MTU

Maximum transmission unit (MTU) of the content engine interface.

BW

Bandwidth of the interface, in kilobits per second.

DLY

Delay of the interface, in microseconds.

reliability

Reliability of the interface as a fraction of 255 (255/255 is 100 percent reliability), calculated as an exponential average over 5 minutes.

txload

Transmit load on the interface as a fraction of 255 (255/255 is completely saturated), calculated as an exponential average over 5 minutes.

rxload

Receive load on the interface as a fraction of 255 (255/255 is completely saturated), calculated as an exponential average over 5 minutes.

Encapsulation

Encapsulation method assigned to the interface.

loopback

Indicates whether loopback is set.

Keepalive

Indicates whether keepalives are set and the interval between keepalives if they have been set.

ARP type...Timeout

Type of Address Resolution Protocol (ARP) assigned and length of timeout.

Last input

Number of hours, minutes, and seconds since the last packet was successfully received by the interface and processed locally on the router. This field is useful for detecting when a dead interface failed.

Note This field is not updated by fast-switched traffic.

output

Number of hours, minutes, and seconds since the last packet was successfully transmitted by the interface. This field is useful for detecting when a dead interface failed.

output hang

Number of hours, minutes, and seconds (or never) since the interface was last reset because a transmission 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

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.

Asterisks (***) indicate that the elapsed time is too large to be displayed.

A time of all zeroes (0:00:00) indicates that the counters were cleared more than 231 ms (and less than 232 ms) ago.

Input queue

Number of packets in the input queue. Each number is followed by a slash, the maximum size of the queue, and the number of packets dropped because of a full queue.

Total output drops

Number of packets in the output queue that have been dropped because of a full queue.

Queueing strategy

Queueing strategy applied to the interface, which is configurable under the interface. The default is FIFO.

Output queue

Number of packets in the output queue. Each number is followed by a slash, the maximum size of the queue, and the number of packets dropped because of 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. If the interface is not in promiscuous mode, it senses network traffic that it sends and receives (rather than all network traffic).

The 5-minute input and output rates should be used only as an approximation of traffic per second during a given 5-minute period. These rates are exponentially weighted averages with a time constant of 5 minutes. A period of four time constants must pass before the average will be within 2 percent of the instantaneous rate of a uniform stream of traffic over that period.

Note The 5-minute period referenced in this output is a load interval that is configurable under the interface. The default value is 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 of noise on serial lines are often responsible for no input buffer events.

Received...broadcasts

Number of broadcasts received.

runts

Number of packets that are discarded because they are smaller than the minimum packet size of the medium. For instance, any Ethernet packet that is less than 64 bytes is considered a runt.

giants

Number of packets that are discarded because they exceed the maximum packet size of the medium. For example, any Ethernet packet that is greater than 1518 bytes is considered a giant.

throttles

Number of times that the interface requested another interface within the router to slow down.

input errors

Errors that include runts, giants, no buffer, cyclic redundancy check (CRC), frame, overrun, and ignored counts. Other input-related errors can also cause the input errors count to be increased, and some datagrams may have more than one error; therefore, this sum may not balance with the sum of enumerated input error counts.

CRC

Errors created when the CRC 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 that is transmitting bad data.

frame

Number of packets received incorrectly that have a CRC error and a non integer number of octets. On a LAN, this is usually the result of collisions or a malfunctioning Ethernet device.

overrun

Number of times that the 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 that were ignored by the interface because the interface hardware ran low on internal buffers. These buffers are different from system buffer space described. Broadcast storms and bursts of noise can cause the ignored count to increase.

input packets with dribble condition detected

Number of packets with dribble condition. Dribble bit error indicates that a frame is slightly too long. This frame error counter is incremented just for informational purposes; the router accepts the frame.

packets output

Total number of messages that have been transmitted by the system.

bytes

Total number of bytes, including data and MAC encapsulation, that have been transmitted by the system.

underruns

Number of times that the transmitter has run faster than the router could 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 content engine that is being examined. Note that this may not balance with the sum of the enumerated output errors, because 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 that have been retransmitted because of 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 that were 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.

babbles

Count of frames greater than 1518 bytes that have been transmitted, indicating that the transmitter has been on the interface longer than the time necessary to transmit the largest frame.

late collision

Number of late collisions. A collision becomes a late collision when it occurs after the preamble has been transmitted.

deferred

Deferred indicates that the chip, while ready to transmit a frame, had to defer because the carrier was asserted.

lost carrier

Number of times that the carrier was lost during transmission.

no carrier

Number of times that the carrier was not present during the transmission.

output buffer failures, output buffers swapped out

Number of failed buffers and number of buffers swapped out.

The following is sample output from two Cisco AS5800 router shelves configured as a failover pair. The active router shelf is initially RouterA. The show redundancy history and show redundancy commands have been issued. The show redundancy command shows that failover is enabled, shows the configured group number, and shows that this router shelf is the active one of the pair. Compare this output with that from the backup router shelf (RouterB) further below.

Note When RouterA is reloaded, thereby forcing a failover, new entries are shown on RouterB when a show redundancy history command is issued after failover has occurred.

Usage Guidelines

The purpose of this command is to convert the collection of the 28 T1 controllers comprising the T3 controller into individual T1 controllers that the system can use. In other words, the Cisco AS5800 access server cannot pass data until a T1 controller is configured (using the controller t1 command), and you cannot configure a T1 controller until it has been created using the t1 command.

Examples

The following example configures a logical T1 controller at T1 time slot 1 for the T3 controller located in shelf 1, slot 4, port 0. Note that you have to enter the command from controller configuration mode.
Router(config)# controller t3 1/4/0
Router(config-controller)# t1 1 controller
Router(config-controller)# end

t1 bert

To enable or disable a bit error rate tester (BERT) test pattern for a T1 channel on the Channelized T3 Interface Processor (CT3IP) in Cisco 7500 series routers, use the t1 bert controller configuration command. To disable a BERT test pattern, use the no form of this command.

t1 channel bert pattern {0s | 1s | 2^15 | 2^20 | 2^23} interval minutes
no t1 channel bert pattern {0s | 1s | 2^15 | 2^20 | 2^23} interval minutes
Syntax Description

channel

Number between 1 and 28 that indicates the T1 channel.

pattern

Specifies the length of the repeating BERT test pattern.

0s

0s—Repeating pattern of zeros (...000...).

1s

1s—Repeating pattern of ones (...111...).

2^15

215—Pseudorandom repeating pattern that is 32,767 bits in length.

2^20

220—Pseudorandom repeating pattern that is 1,048,575 bits in length.

2^23

223—Pseudorandom repeating pattern that is 8,388,607 bits in length.

interval minutes

Specifies the duration of the BERT test. The interval can be a value from 1 to 14,400 minutes.

Defaults

No BERT test is performed.

Command Modes

Controller configuration

Command History

Release

Modification

11.3

This command was introduced.

Usage Guidelines

The BERT test patterns from the CT3IP are framed test patterns (that is, the test patterns are inserted into the payload of the framed T1 signal).

To view the BERT results, use the show controller t3 or show controller t3 brief EXEC command. The BERT results include the following information:

•Type of test pattern selected

•Status of the test

•Interval selected

•Time remaining on the BERT test

•Total bit errors

•Total bits received

When the T1 channel has a BERT test running, the line state is DOWN. Also, when the BERT test is running and the Status field is Not Sync, the information in the total bit errors field is not valid. When the BERT test is done, the Status field is not relevant.

The t1 bert command is not written to NVRAM because it is only used for testing the T1 channel for a short predefined interval and for avoiding accidentally saving the command, which could cause the interface not to come up the next time the router reboots.

Note T1 channels on the CT3IP are numbered 1 to 28 rather than the more traditional zero-based scheme (0 to 27) used with other Cisco products. This numbering scheme ensures consistency with telco numbering schemes for T1 channels within channelized T3 equipment.

Examples

The following example runs a BERT test pattern of all zeros for 30 minutes on T1 channel 6 on the CT3IP in slot 9:
Router(config)# controller t3 9/0/0
Router(config-controller)# t1 6 bert pattern 0s interval 30

Usage Guidelines

If you do not specify the t1 clock source command, the default clock source of internal is used by all the T1s on the CT3IP.

You can also set the clock source for the CT3IP by using the clock source (CT3IP) controller configuration command.

Note T1 channels on the CT3IP are numbered 1 to 28 rather than the more traditional zero-based scheme (0 to 27) used with other Cisco products. This numbering scheme ensures consistency with telco numbering schemes for T1 channels within channelized T3 equipment.

This command does not have a no form.

Examples

The following example sets the clock source for T1 6 and T1 8 on the CT3IP to line:
Router(config)# controller t3 9/0/0
Router(config-controller)# t1 6 clock source line
Router(config-controller)# t1 8 clock source line

t1 external

To specify that a T1 channel on the Channelized T3 Interface Processor (CT3IP) in Cisco 7500 series routers is used as an external port so that the T1 channel can be further multiplexed on the Multichannel Interface Processor (MIP) or other multiplexing equipment, use the t1 external command in controller configuration mode. To remove a T1 as an external port, use the no form of this command.

t1 external channel [cablelength feet] [linecode ami | b8zs]
no t1 external channel
Syntax Description

channel

Number 1, 2, or 3 that indicates the T1 channel.

cablelength feet

(Optional) Specifies the cable length, in feet, from the T1 channel to the external CSU or MIP. Values are 0 to 655 feet. The default is 133 feet.

linecode ami | b8zs

(Optional) Specifies the line coding used by the T1. Values are alternate mark inversion (AMI) or bipolar 8 zero suppression (B8ZS). The default is B8ZS.

Defaults

No external T1 is specified.

The default cable length is 133 feet.

The default line coding is B8ZS.

Command Modes

Controller configuration

Command History

Release

Modification

11.3

This command was introduced.

Usage Guidelines

The first three T1 channels (1, 2, and 3) of the CT3IP can be broken out to the DSUP-15 connectors on the CPT3IP so that the T1 channel can be further demultiplexed by the MIP on the same router or on another router.

After you configure the external T1 channel, you can continue configuring it as a channelized T1 (also referred to as a fractional T1) from the MIP. All channelized T1 commands might not be applicable to the T1 interface. After you configure the channelized T1 on the MIP, you can continue configuring it as you would a normal serial interface. All serial interface commands might not be applicable to the T1 interface.

The line coding on the T1 channel and the MIP must be the same. Because the default line coding format on the T1 channel is B8ZS and the default line coding on the MIP is AMI, you must change the line coding on the MIP or on the T1 so that they match.

To determine if the external device connected to the external T1 port is configured and cabled correctly before configuring an external port, use the show controllers t3 command and locate the line Ext1... in the display output. The line status can be one of the following:

•LOS—Loss of signal indicates that the port is not receiving a valid signal. This is the expected state if nothing is connected to the port.

•AIS—Alarm indication signal indicates that the port is receiving an all-ones signal.

•OK—A valid signal is being received and the signal is not an all-ones signal.

Note T1 channels on the CT3IP are numbered 1 to 28 rather than the more traditional zero-based scheme (0 to 27) used with other Cisco products. This numbering scheme ensures consistency with telco numbering schemes for T1 channels within channelized T3 equipment.

Note Although you can specify a cable length from 0 to 655 feet, the hardware only recognizes the following ranges: 0 to 133, 134 to 266, 267 to 399, 400 to 533, and 534 to 655. For example, entering 150 feet uses the 134 to 266 range. If you later change the cable length to 200 feet, there is no change because 200 is within the 134 to 266 range. However, if you change the cable length to 399, the 267 to 399 range is used. The actual number you enter is stored in the configuration file.

Examples

The following example configures the T1 1 on the CT3IP as an external port using AMI line coding and a cable length of 300 feet:
Router(config)# controllers t3 9/0/0
Router(config-controller)# t1 external 1 cablelength 300 linecode ami

Note T1 channels on the CT3IP are numbered 1 to 28 rather than the more traditional zero-based scheme (0 to 27) used with other Cisco products. This numbering scheme ensures consistency with telco numbering schemes for T1 channels within channelized T3 equipment.

This command does not have a no form.

Examples

The following example sets the framing for the T1 6 and T1 8 on the CT3IP to super frame:
Router(config)# controller t3 9/0/0

Router(config-controller)# t1 8 framing sf
t1 linecode

To specify the type of line coding used by the T1 channels on the Channelized T3 Interface Processor (CT3IP) in Cisco 7500 series routers, use the t1 linecode command in controller configuration mode.

t1 channel linecode {ami | b8zs}
Syntax Description

channel

Number between 1 and 28 that indicates the T1 channel.

ami

Specifies that alternate mark inversion (AMI) line coding is used by the T1 channel.

b8zs

Specifies that bipolar 8 zero suppression (B8ZS) line coding is used by the T1 channel. This is the default.

Defaults

B8ZS

Command Modes

Controller configuration

Command History

Release

Modification

11.3

This command was introduced.

Usage Guidelines

If you do not specify the t1 linecode command, the default B8ZS is used.

AMI Line Coding

If you select ami line coding for the T1 channel, you must also invert the data on the T1 channel by using the invert data interface command. This is required because the T1 channel is bundled into the T3 signal, so there are no local T1 line drivers and receivers associated with it. Therefore, the t1 channel linecode ami command does not modify local line driver settings. Rather, it advises the CT3IP what line code the remote T1 is using. The CT3IP uses this information solely for the purpose of determining whether or not to enable the pulse density enforcer for that T1 channel.

B8ZS Line Coding

When you select b8zs line coding, the pulse density enforcer is disabled. When you select ami line coding, the pulse density enforcer is enabled. To avoid having the pulse density enforcer corrupt data, the T1 channel should be configured for inverted data.

Note T1 channels on the CT3IP are numbered 1 to 28 rather than the more traditional zero-based scheme (0 to 27) used with other Cisco products. This numbering scheme ensures consistency with telco numbering schemes for T1 channels within channelized T3 equipment.

This command does not have a no form.

Examples

The following example sets the line coding for T1 channel 16 on the CT3IP to AMI:

t1 test channel [cablelength feet] [linecode {ami | b8zs}]
no t1 test channel
Syntax Description

channel

Number between 1 and 28 that indicates the T1 channel.

cablelength feet

(Optional) Specifies the cable length from the T1 channel to the external CSU or Multi-Channel Interface Processor (MIP). Values are 0 to 655 feet. The default cable length is 133 feet.

linecode {ami | b8zs}

(Optional) Specifies the line coding format used by the T1 channel. Values are alternate mark inversion (AMI) or bipolar 8 zero suppression (B8ZS). The default is B8ZS.

Defaults

No test port is configured.

The default cable length is 133 feet.

The default line coding is B8ZS.

Usage Guidelines

You can use the T1 test port available on the CT3IP to break out any of the 28 T1 channels for testing (for example, 24-hour bit error-rate tester (BERT )testing as is commonly done by telephone companies before a line is brought into service).

The T1 test port is also available as an external port. For more information on configuring an external port, see the t1 external controller configuration command.

To determine if the external device connected to the T1 test port is configured and cabled correctly before configuring a test port, use the show controllers t3 command and locate the line Ext1... in the display output. The line status can be one of the following:

•LOS—Loss of signal indicates that the port is not receiving a valid signal. This is the expected state if nothing is connected to the port.

•AIS—Alarm indication signal indicates that the port is receiving an all-ones signal.

•OK—A valid signal is being received and the signal is not an all-ones signal.

Note T1 channels on the CT3IP are numbered 1 to 28 rather than the more traditional zero-based scheme (0 to 27) used with other Cisco products. This numbering scheme ensures consistency with telco numbering schemes for T1 channels within channelized T3 equipment.

Note Although you can specify a cable length from 0 to 655 feet, the hardware only recognizes the following ranges: 0 to 133, 134 to 266, 267 to 399, 400 to 533, and 534 to 655. For example, entering 150 feet uses the 134 to 266 range. If you later change the cable length to 200 feet, there is no change because 200 is within the 134 to 266 range. However, if you change the cable length to 399, the 267 to 399 range is used. The actual number you enter is stored in the configuration file.

Examples

The following example configures T1 6 on the CT3IP as a test port using the default cable length and line coding:
Router(config)# controller t3 9/0/0
Router(config-controller)#  t1 test 6

Command

Description

show controllers t3

Displays the hardware and software driver information for a T3 controller.

t1 external

Specifies that a T1 channel on the CT3IP in Cisco 7500 series routers is used as an external port so the T1 channel can be further multiplexed on the MIP or other multiplexing equipment.

t1 timeslot

To specify the time slots and data rate used on each T1 channel on the Channelized T3 Interface Processor (CT3IP) in Cisco 7500 series routers, use the t1 timeslot command in controller configuration mode. To remove the configured T1 channel, use the no form of this command.

t1 channel timeslot range [speed {56 | 64}]
no t1 channel timeslot
Syntax Description

channel

Number between 1 and 28 that indicates the T1 channel.

range

Specifies the time slots assigned to the T1 channel. The range can be 1 to 24. A dash represents a range of time slots, and a comma separates time slots. For example, 1-10,15-18 assigns time slots 1 through 10 and 15 through 18.

speed {56 | 64}

(Optional) Specifies the data rate for the T1 channel. Values are 56 kbps or 64 kbps. The default is 64 kbps. The 56-kbps speed is valid only for T1 channels 21 through 28.

Defaults

No time slots are specified for the T1 channel.

The default data rate is 64 kbps.

Usage Guidelines

You must specify the time slots used by each T1 channel.

Note T1 channels on the CT3IP are numbered 1 to 28 rather than the more traditional zero-based scheme (0 to 27) used with other Cisco products. This numbering scheme ensures consistency with telco numbering schemes for T1 channels within channelized T3 equipment.

Examples

The following example assigns time slots 1 through 24 to T1 1 for full T1 bandwidth usage:
Router(config)# controller t3 9/0/0
Router(config-controller)# t1 1 timeslots 1-24
The following example assigns time slots 1 to 5 and 20 to 23 to T1 6 for fractional T1 bandwidth usage:
Router(config)# controller t3 9/0/0
Router(config-controller)# t1 6 timeslots 1-5,20-23
The following example configures T1 8 for n x 56 (where n is 24) bandwidth usage:
Router(config)# controller t3 9/0/0
Router(config-controller)# t1 8 timeslots 1-24 speed 56
t1 yellow

To enable detection and generation of yellow alarms for a T1 channel on the Channelized T3 Interface Processor (CT3IP) in Cisco 7500 series routers, use the t1 yellow command in controller configuration mode. To disable the detection and generation of yellow alarms, use the no form of this command.

t1 channel yellow {detection | generation}
no t1 channel yellow {detection | generation}
Syntax Description

channel

Number between 1 and 28 that indicates the T1 channel.

detection

Detects yellow alarms. This is the default, along with generation.

generation

Generates yellow alarms. This is the default, along with detection.

Defaults

Yellow alarms are detected and generated on the T1 channel.

Usage Guidelines

If the T1 framing type is super frame (SF), you should consider disabling yellow alarm detection because the yellow alarm can be incorrectly detected with SF framing.

Note T1 channels on the CT3IP are numbered 1 to 28 rather than the more traditional zero-based scheme (0 to 27) used with other Cisco products. This numbering scheme ensures consistency with Telco numbering schemes for T1 channels within channelized T3 equipment.

Examples

The following example disables the yellow alarm detection on T1 channel 6 on the CT3IP:
Router(config)# controller t3 9/0/0
Router(config-controller)# t1 6 framing sf
Router(config-controller)# no t1 6 yellow detection
