service-module t1 timeslots

To define timeslots that constitute a fractional T1/T1 (FT1/T1) channel, use the service-module t1 timeslots interface configuration command. To resume the default setting (all FT1/T1 timeslots transmit at 64 kbps), use the no form of this command.

service-module t1 timeslots {range | all} [speed {56 | 64}]

no service-module t1 timeslots {range | all}

Syntax Description

range	The DS0 timeslots that constitute the FT1/T1 channel. The range is from 1 to 24, where the first timeslot is numbered 1 and the last timeslot is numbered 24. Specify this field by using a series of subranges separated by commas.
all	Selects all FT1/T1 timeslots.
speed	(Optional) Specifies the timeslot speed.
56	(Optional) 56 kbps.
64	(Optional) 64 kbps. This is the default.

Defaults

64 kbps is the default for all timeslots.

Command History

Release	Modification
11.2	This command was introduced.

Usage Guidelines

This command specifies which timeslots are used in fractional T1 operation and determines the amount of bandwidth available to the router in each FT1/T1 channel.

The timeslot range must match the timeslots assigned to the channel group. Your service provider defines the timeslots that comprise a channel group.

To use the entire T1 line, enable the service-module t1 timeslots all command.

Examples

The following example displays a series of timeslot ranges and a speed of 64 kbps:

Router(config-if)#  service-module t1 timeslots 1-10,15-20,22 speed 64

Related Commands

Command	Description
service-module t1 data-coding	Guarantees the ones density requirement on an AMI line using the fractional T1/T1 module.
service-module t1 linecode	Selects the linecode for the fractional T1/T1 module.

show aps

To display information about the current automatic protection switching (APS) feature, use the show aps privileged EXEC command.

show aps

Syntax Description

This command has no arguments or keywords.

Command Modes

Privileged EXEC

Command History

Release	Modification
11.1 CC	This command was introduced.

Examples

The following is an example of the show aps command on a router configured with a working interface. In this example, POS interface 0/0/0 is configured as a working interface in group 1, and the interface is selected (that is, active).

router1# show aps

POS0/0/0 working group 1 channel 1 Enabled Selected

The following is an example of the show aps command on a router configured with a protect interface. In this example, POS interface 2/0/0 is configured as a protect interface in group 1, and the interface is not selected (the ~ indicates that the interface is not active). The output also shows that the working channel is located on the router with the IP address 15.1.6.1 and that the interface is currently selected (that is, active).

router2# show aps

POS2/0/0 protect group 1 channel 0 bidirectional ~Selected

        Rx_K1= 0, Rx_K2= 0 Tx_K1= 0 Tx_K2= 5

        Working channel 1 at 15.1.6.1 Enabled 

For the K1 field (8 bits), the first 4 bits indicate the channel number that has made the request, and the last 4 bits map to the requests (local or external) listed in Table 14. For the K2 field (8 bits), the first 4 bits indicate the channel number bridged onto the protect line, the next bit is the architecture used, and the last 3 bits indicate the mode of operation or non-APS use listed in Table 14.

Table 14 K1 Bit Descriptions 

Bits (hexadecimal)	Description
K1 bits 8765	K1 bits 8 through 5: Channel number that made the request.

Interface Processors (IPs) must respond to cBus commands within the prescribed time. Sometimes the 
IPs may not respond within this time due to heavy traffic or some problem in the IP's hardware or 
firmware. Then the IP's response to cBus commands may be out of sync. When this situation occurs, 
the Route Processor (RP) must resync the IP. Currently CIP, FSIP, FEIP, RVIP, and SVIP support the 
resync mechanism.

Table 17 describes significant fields shown in the display.

Table 17 show controllers cbus Field Descriptions

Field	Description
timeouts	Number of times the IP did not respond to a cBus command within the allotted time.
resyncs	If the IP supports the resync mechanism, then this count is the same as the timeouts value.
failures	Number of resynchronization failures.
max phase count	High count of phase synchronization; that is, the maximum attempts tried before the sync was successful. Maximum number of resync attempts is 16 before the failures counter is incremented.

---

Note The timeouts, resyncs, and max phase count values do not imply any problem in the IP. The failures value implies a problem and usually end in a console error message.

Note The interface type is only queried at startup. If the hardware changes subsequent to initial startup, then the wrong type is reported. This has no adverse effect on the operation of the software. For instance, if a DCE cable is connected to a dual-mode V.35 applique after the unit has been booted, then the display presented for the show interfaces command incorrectly reports attachment to a DTE device although the software recognizes the DCE interface and behaves accordingly.

Table 23 describes the fields shown in the display.

Table 23 show controllers pos Field Descriptions 

Field	Description
POS2/0/0	Slot number of the POS interface.
LOF	Section loss of frame is detected when a severely error framing (SEF) defect on the incoming SONET signal persist for 3 milliseconds.
LOS	Section loss of signal is detected when an all-zeros pattern on the incoming SONET signal lasts 19 plus or minus 3 microseconds or longer. This defect might also be reported if the received signal level drops below the specified threshold.
BIP(B1)/BIP(B2)/BIP(B3)	Bit interleaved parity (BIP). For B1, the BIP error report is calculated by comparing the BIP-8 code with the BIP-8 code extracted from the B1 byte of the following frame. Differences indicate that section-level bit errors have occurred. For B2, the BIP error report is calculated by comparing the BIP-8/24 code with the BIP-8 code extracted from the B2 byte of the following frame. Differences indicate that line-level bit errors have occurred. For B3, the BIP error report is calculated by comparing the BIP-8 code with the BIP-8 code extracted from the B3 byte of the following frame. Differences indicate that path-level bit errors have occurred.
AIS	Alarm indication signal. A line alarm indication signal is sent by the section terminating equipment (STE) to alert the downstream line terminating equipment (LTE) that a loss of signal (LOS) or loss of frame (LOF) defect has been detected on the incoming SONET section. A path alarm indication signal is sent by the LTE to alert the downstream path terminating equipment (PTE) that it has detected a defect on its incoming line signal.
RDI	Remote defect indication. A line remote defect indication is reported by the downstream LTE when it detects LOF, LOS, or AIS. A path remote defect indication is reported by the downstream PTE when it detects a defect on the incoming signal.
FEBE	Far end block errors. Line FEBE (accumulated from the M0 or M1 byte) is reported when the downstream LTE detects BIP(B2) errors. Path FEBE (accumulated from the G1 byte) is reported when the downstream PTE detects BIP(B3) errors.
LOP	Path loss of pointer is reported as a result of an invalid pointer (H1, H2) or an excess number of new data flag (NDF) enabled indications.
NEWPTR	Inexact count of the number of times that the SONET framer has validated a new SONET pointer value (H1, H2).
PSE	Inexact count of the number of times that the SONET framer has detected a positive stuff event in the received pointer (H1, H2).
NSE	Inexact count of the number of times that the SONET framer has detected a negative stuff event in the received pointer (H1, H2).
Active Defects	List of all currently active SONET defects.
Active Alarms	List of current alarms as enforced by Sonet Alarm Hierarchy.
Alarm reporting enabled for	List of alarms for which you enabled reporting with the pos report interface command.
APS	Automatic protection switching.
COAPS	An inexact count of the number of times that a new APS value has been detected in the K1, K2 bytes.
PSBF	An inexact count of the number of times that a protection switching byte failure has been detected (no three consecutive SONET frames contain identical K1 bytes).
PSBF_state	Protection switching byte failure state.
Rx(K1/K2)/Tx(K1/K2)	Contents of the received and transmitted K1 and K2 bytes.
S1S0	The two S bits received in the last H1 byte.
C2	The value extracted from the SONET path signal label byte (C2).
CLOCK RECOVERY	The SONET clock is recovered using information in the SONET overhead. RDOOL is an inexact count of the number of times that Receive Data Out Of Lock has been detected, which indicates that the clock recovery phased lock loop is unable to lock to the receive stream.
PATH TRACE BUFFER	SONET path trace buffer is used to communicate information regarding the remote host name, interface name/number, and IP address. This is a Cisco-proprietary use of the J1 (path trace) byte.
BER thresholds	List of the bit error rate (BER) thresholds that you configured with the pos threshold interface command.
TCA thresholds	List of threshold crossing alarms (TCAs) that you configured with the pos threshold interface command.

Field	Description
POS1/0	Slot number of the POS interface.
Line coding	Shows the current line encoding type, either return to zero (RZ) or nonreturn to zero (NRZ).
Line type	Line type for this interface. Optical line types can be either long range (LONG) or short range (SHORT), and either single mode (SM) or multimode (MM).
Data in current interval	Shows the current accumulation period, which rolls into the 24-hour accumulation every 15 minutes. Accumulation period is from 1 to 900 seconds. The oldest 15-minute period falls off the back of the 24-hour accumulation buffer.
Errored Secs	An errored second is a second in which one of the following is detected: •One or more coding violations. •One or more incoming defects (for example, a severely errored frame (SEF) defect, an LOS defect, an AIS defect, or an LOP defect).
Severely Err Secs	A severely errored second (SES) is a second with one of the following errors: •A certain number of coding violations. The number is dependent on the line rate and the BER. •A certain number of incoming defects.
Coding Violations	Number of coding violations for the current interval. Coding violations are defined as BIP errors that are detected in the incoming signal. The coding violations counter is incremented for each BIP error detected.
Sev Err Framing Secs	Severely errored framing seconds (SEFS) are seconds with one or more SEF defects.
Unavailable Secs	Total number of seconds for which the interface is unavailable. The interface is considered to be unavailable after a series of ten consecutive SESs.

Table 25 show controller t1 Field Descriptions 

Field	Description
T1 0/0 is up.	The T1 controller 0 in slot 0 is operating. The controller's state can be up, down, administratively down. Loopback conditions are shown by (Locally Looped) or (Remotely Looped).
No alarms detected.	Any alarms detected by the controller are displayed here. Possible alarms are as follows: •Transmitter is sending remote alarm. •Transmitter is sending AIS. •Receiver has loss of signal. •Receiver is getting AIS. •Receiver has loss of frame. •Receiver has remote alarm. •Receiver has no alarms.
Data in current interval (725 seconds elapsed)	Shows the current accumulation period, which rolls into the 24-hour accumulation every 15 minutes. Accumulation period is from 1 to 900 seconds. The oldest 15 minute period falls off the back of the 24-hour accumulation buffer.
Line Code Violations	Indicates the occurrence of either a Bipolar Violation (BPV) or Excessive Zeros (EXZ) error event.
Path Code Violations	Indicates a frame synchronization bit error in the D4 and E1-noCRC formats, or a CRC error in the ESF and E1-CRC formats.
Slip Secs	Indicates the replication or deletion of the payload bits of a DS1 frame. A slip may be performed when there is a difference between the timing of a synchronous receiving terminal and the received signal.
Fr Loss Secs	Indicates the number of seconds an Out-of-Frame error is detected.
Line Err Secs	Line Errored Seconds (LES) is a second in which one or more Line Code Violation errors are detected.

Clock Source is Internal	Clock source on the CT3IP. Values are: internal or line.
BERT test result	BERT test information is available if the t1 bert controller command is enabled for the T1 channel on the CT3IP. The BERT results include the following information: •Test Pattern—Type of test pattern selected. •Status—Status of the test. •Sync Detected—Number of times the pattern synch is detected (that is, the number of times the pattern goes from No Sync to Sync). •Interval—Duration selected. •Time Remain—Time remaining on the BERT test. •Bit Errors(Sync BERT Started)—Number of bit errors during the BERT test. •Bit Errors(Sync last Sync)—Number of bit errors since the last patter sync was detected. •Bits Received—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.
Data in current interval (39 seconds elapsed)	Shows the current accumulation period, which rolls into the 24-hour accumulation every 15 minutes. Accumulation period is from 1 to 900 seconds. The oldest 15-minute period falls off the back of the 24-hour accumulation buffer.

P-bit Severely Err Secs	P-bit severely errored seconds (PSES) is a second with 44 or more PCVs, one or more Out-of-Frame defects, or a detected incoming AIS. This gauge is not incremented when unavailable seconds are counted.
Severely Err Framing Secs	Severely errored framing seconds (SEFS) is a second with one or more Out-of-Frame defects or a detected incoming AIS.
Unavailable Secs	Unavailable seconds (UAS) are calculated by counting the number of seconds that the interface is unavailable. For more information, refer to RFC 1407, "DS3 MIB Variables."
Line Err Secs	Line errored seconds (LES) is a second in which one or more code violations occurred or one or more LOS defects.
C-bit Errored Secs	C-bit errored seconds (CES) is a second with one or more C-bit code violations (CCV), one or more Out-of-Frame defects, or a detected incoming AIS. This gauge is not incremented when UASs are counted.
C-bit Severely Errored Secs	C-bit severely errored seconds (CSES) is a second with 44 or more CCVs, one or more Out-of-Frame defects, or a detected incoming AIS. This gauge is not incremented when UASs are counted.
Total Data (last 1 15 minute intervals)	Shows the last 15-minute accumulation period.
T1 1 is up	T1 channel is operating. The channel's state can be up, down, administratively down. Loopback conditions are shown by (Locally looped) or (Remotely looped).
speed	Speed of the T1 channel in kbps.
non-inverted data	Indicates if the T1 channel is configured for inverted data.
timeslots	Timeslots assigned to the T1 channel.
FDL per AT&T 54016 spec.	Performance monitoring is via Facility Data Link per ANSI T1.403.
No alarms detected	Any alarms detected by the T1 controller are displayed here. Possible alarms are as follows: •Transmitter is sending remote alarm. •Transmitter is sending AIS. •Receiver has loss of signal. •Receiver is getting AIS. •Receiver has loss of frame. •Receiver has remote alarm. •Receiver has no alarms.
Framing is ESF	Type of framing used on the T1 channel. Values are: ESF or SF.
LineCode is B8ZS	Type of line coding used on the T1 channel. Values are: B8ZS or AMI.
Clock Source is Internal	Clock source on the T1 channel. Values are: internal or line.
Path Code Violations	Path coding violation (PCV) error event is a frame synchronization bit error in the D4 and E1-noCRC formats or a CRC error in the ESF and E1-CRC formats.
Slip Secs	Controlled slip second (CSS) is a one-second interval containing one or more controlled slips.
Fr Loss Secs	Frame loss seconds (SELS) is the number of seconds an Out-of-Frame error is detected.
Line Err Secs	Line errored seconds (LES) is a second in which one or more line code violation errors are detected.
Degraded Mins	Degraded minute (DM) is one in which the estimated error rate exceeds 1E-6 but does not exceed 1E-3. For more information, refer to RFC 1406, "Definitions of Managed Objects for DS1 and E1 Interface Types."
Errored Secs	Errored seconds (ES) is a second with one or more path coding violations, one or more Out-of-Frame defects, or one or more controlled slip events or a detected AIS defect.
Bursty Err Secs	Bursty errored seconds (BES) is a second with fewer than 320 and more than one path coding violation error events, no Severely Errored Frame defects, and no detected incoming AIS defects. Controlled slips are not included in this parameter.
Severely Err Secs	Severely errored seconds (SES) is a second with 320 or more path code violation errors events, one or more Out-of-Frame defects, or a detected AIS defect.
Stuffed Secs	Stuffed seconds (SS) is a second in which one more bit stuffings take place. This happens when the Pulse Density Enforcer detects a potential violation in the output stream and inserts a 1 to prevent it. Such bit stuffings corrupt user data and indicate the network is configured incorrectly. This counter can be used to help diagnose this situation.

Table 28 describes the fields shown in the show controller t3 display.

Table 28 show controller t3 Command Field Descriptions 

Field	Description
T3 1/4/0 is up	T3 controller connected to this Cisco AS5800 access server in shelf 1, slot 4, port 0 is up. The controller's state can be up, down, or administratively down. Loopback conditions are shown by Locally looped or Remotely Looped.
Applique type is ...	Describes the type of controller.
No alarms detected	Any alarms detected by the controller are displayed here. Possible alarms are as follows: •Transmitter is sending remote alarm. •Transmitter is sending alarm indication signal (AIS). •Receiver has loss of signal (LOS). •Receiver is getting AIS. •Receiver has loss of frame (LOF). •Receiver has remote alarm. •Receiver has no alarms.
MDL transmission ...	Maintenance Data Link status (either enabled or disabled). Used for carrying performance information and control signals across the network towards the far end T3 unit. It is the counterpart of Facility Data Link (FDL) in a T1 link.
FEAC code received	Whether or not a far-end alarm code request is being received. Possible values are as follows: •DS3 Eqpt. Failure (SA) •DS3 LOS/HBER •DS3 Out-of-Frame •DS3 AIS Received •DS3 IDLE Received •DS3 Eqpt. Failure (NSA) •Common Eqpt. Failure (NSA) •Multiple DS1 LOS/HBER •DS1 Eqpt. Failure •Single DS1 LOS/HBER •DS1 Eqpts Failure (NSA) •No code is being received
Framing is ...	Standard T3 framing type: M23, C-Bit, or Auto-detect.
Line Code is ...	Standard T3 line-coding format. In this example, the line-coding format is bipolar 3-zero substitution (B3ZS).
Clock Source is ...	The source of the synchronization signal (clock): line or internal. In this example, the line is providing the clock signal.
Data in current interval ...	Summary statistics for T3 signal quality for the current time interval of 900 seconds (15 minutes). In this example, the statistics are for current partial interval. Statistics roll into the 24-hour accumulation buffer every 15 minutes. The oldest 15-minute period falls off the back of the 24-hour accumulation buffer.
Line Code Violations	Count of both Bipolar Violations (BPVs) and Excessive Zeros (EXZs) occurring over the accumulation period. An EXZ increments the Line Code Violations (LCV) by one regardless of the length of the zero string.
P-bit Coding Violation	P-bit parity error event. A P-bit parity error event is the occurrence of a received P-bit code on the DS3 M-frame that is not identical to the corresponding locally calculated code. Referred to as PVC.
C-bit Coding Violation	Count of coding violations reported via the C-bits. For C-bit parity, it is the count of CP-bit parity errors occurring in the accumulation interval. Referred to as CCV.
P-bit Err Secs	Number of seconds with one or more PCVs, one or more Out-of-Frame defects, or a detected incoming AIS. This gauge is not incremented when unavailable seconds are counted.
P-bit Severely Err Secs	Number of seconds with 44 or more PCVs, one or more Out-of-Frame defects, or a detected incoming AIS. This gauge is not incremented when unavailable seconds are counted.
Severely Err Framing Secs	Number of a seconds with one or more Out-of-Frame defects or a detected incoming AIS.
Unavailable Secs	Number of seconds during which the interface was not available in this interval. Referred to as UAS.
Line Errored Secs	Number of seconds in this interval during one or more code violations or one or more LOS defects.
C-bit Errored Secs	Number of seconds with one or more C-bit code violations (CCV), one or more Out-of-Frame defects, or a detected incoming AIS. This gauge is not incremented when UASs are counted. Referred to as CES.
C-bit Severely Errored Secs	Number of seconds with 44 or more CCVs, one or more Out-of-Frame defects, or a detected incoming AIS. This gauge is not incremented when UASs are counted.
Total Data (last ... 15 minute intervals)	Summary statistics for T3 signal quality for 15-minute intervals. Every 24 hours (96 intervals) the counters in this data block clear.

show controllers token

To display information about memory management and error counters on the Token Ring Interface Processor (TRIP) for the Cisco 7500 series routers, use the show controllers token privileged EXEC command.

show controllers token

Syntax Description

This command has no arguments or keywords.

Command Modes

Privileged EXEC

Command History

Release	Modification
10.0	This command was introduced.
11.3(3)T	The information was modified to include the PA-4R-FDX full-duplex Token Ring port adapter.

Usage Guidelines

Depending on the card being used, the output can vary. This command also displays information that is proprietary to Cisco Systems. Thus, the information that the show controllers token command displays is of primary use to Cisco technical personnel. Information that is useful to users can be obtained with the show interfaces tokenring command, which is described later in this chapter.

Examples

An example for the show controllers token command on the Cisco 7500 follows:

show hub

To display information about the hub (repeater) on an Ethernet interface of a Cisco 2505 or Cisco 2507 router, use the show hub EXEC command.

show hub [ethernet number [port [end-port]]]

Syntax Description

ethernet	(Optional) Indicates that this is an Ethernet hub.
number	(Optional) Hub number, starting with 0. Since there is currently only one hub, this number is 0.
port	(Optional) Port number on the hub. On the Cisco 2505 router, port numbers range from 1 through 8. On the Cisco 2507 router, port numbers range from 1 through 16. If a second port number follows, then this port number indicates the beginning of a port range.
end-port	(Optional) Ending port number of a range.

Command Modes

EXEC

Command History

Release	Modification
10.3	This command was introduced.

Usage Guidelines

If you do not specify a port or port range for the show hub command, the command displays all ports (for example, ports 1 through 16 on a Cisco 2507 router) by default. Therefore, the show hub, show hub ethernet 0, and show hub ethernet 0 1 16 commands produce the same result.

If no ports are specified, the command displays some additional data about the internal port. The internal port is the hub's connection to Ethernet interface 0 inside the box. Ethernet interface 0 still exists; physical access to the interface is via the hub.

Examples

The following is an example from the show hub command for hub 0, port 2 only:

Router# show hub ethernet 0 2

Port 2 of 16 is administratively down, link state is down

  0 packets input, 0 bytes

  0 errors with 0 collisions

Table 30 describes significant fields shown in the display.

Table 30 show hub Field Descriptions 

Field	Description
Port ... of ... is administratively down	Port number out of total ports; indicates whether the interface hardware is currently active or down because of the following: •The link-state test failed. •The MAC address mismatched when source address configured. •It has been taken down by an administrator.
link state is up	Indicates whether port has been disabled by the link-test function. If the link-test function is disabled by the user, nothing will be shown here.
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.
errors	Sum of FCS, alignment, too long, short, runts, very long, and rate mismatches.
collisions	Number of messages retransmitted due to Ethernet collisions.
FCS	Counter for the number of frames detected on the port with an invalid frame check sequence.
alignment	Counter for the number of frames of valid length (64 to 1518 bytes) that have been detected on the port with an FCS error and a framing error.
too long	Counter for the number of frames that exceed the maximum valid packet length of 1518 bytes.
short	Counter for the number of instances when activity is detected with duration less than 74 to 82 bit times.
runts	Number of packets that are discarded because they are smaller than the medium's minimum packet size. For example, any Ethernet packet that is less than 64 bytes is considered a runt.
late	Counter for the number of instances when a collision is detected after 480 to 565 bit times in the frame.
very longs	Counter for the number of times the transmitter is active in excess of 4 to 7.5 ms.
rate mismatches	Counter for the number of occurrences when the frequency, or data rate of incoming signal is noticeably different from the local transmit frequency.
auto partitions	Counter for the number of instances where the repeater has partitioned the port from the network.
last source address	Source address of last packet received by this port. Indicates "none" if no packets have been received since power on or a hub reset.
Last clearing of "show hub" counters	Elapsed time since clear hub counters command. Indicates "never" if counters have never been cleared.
Repeater information (Connected to Ethernet0)	Indicates that the following information is about the hub connected to the Ethernet interface shown.
... bytes seen with ... collisions, ... hub resets	Hub resets is the number of times the hub has been reset by network management software or by the clear hub command.
Version/device ID 0/1 (0/1)	Hub hardware version. IMR+ version device of daughter board.
Internal Port (Connected to Ethernet0)	Set of counters for the internal AUI port connected to the Ethernet interface.
