To display information about the current automatic protection switching (APS) feature, use the show aps EXEC command.
show apsThis command has no arguments or keywords.
Privileged EXEC
This command first appeared in Cisco IOS Release 11.1 CC.
The following is sample output 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 sample output 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 12. 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 13.

Table 21 describes the fields shown in the display.
| 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 (+-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 error reported. For B1, the bit interleaved parity 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 bit interleaved parity 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 bit interleaved parity 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. Line alarm indication signal is sent by the section terminating equipment (STE) to alert the downstream line terminating equipment (LTE) that a LOS or LOF defect has been detected on the incoming SONET section. 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. Line remote defect indication is reported by the downstream LTE when it detects LOF, LOS, or AIS. 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 far end block error (accumulated from the M0 or M1 byte) is reported when the downstream LTE detects BIP(B2) errors. Path far end block error (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 | An inexact count of the number of times the SONET framer has validated a new SONET pointer value (H1, H2). |
PSE | An inexact count of the number of times the SONET framer has detected a positive stuff event in the received pointer (H1, H2). |
NSE | An inexact count of the number of times 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 that you enabled reporting for with the pos report interface command. |
APS | Automatic protection switching. |
COAPS | An inexact count of the number of times a new APS value has been detected in the K1, K2 bytes. |
PSBF | An inexact count of the number of times 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. For more information on the K1 field, refer to Table 12. For more information on the K2 field, refer to Table 13. |
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 | SONET clock is recovered using information in the SONET overhead. RDOOL is an inexact count of the number of times Receive Data Out Of Lock has been detected which indicates 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 hostname, 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 you configured with the pos threshold interface command. |
TCA thresholds | List of threshold crossing alarms (TCA) you configured with the pos threshold interface command. |
Use the show controllers serial privileged EXEC command to display information that is specific to the interface hardware.
show controllers serial [slot/port]
slot | (Optional) Slot number of the interface. |
port | (Optional) Port number on the interface. The port value is always 0. |
port-adapter | (Optional) On Cisco 7500 series routers and Cisco 7000 series routers with the RSP7000 and RSP7000CI, the location of the port adapter on a VIP. The value can be 0 or 1. |

This command first appeared in Cisco IOS Release 10.0.
This command was modified in Cisco IOS Release 11.1 CA to include sample output for the PA-E3 and PA-T3 port adapters.
The information displayed is generally useful for diagnostic tasks performed by technical support personnel only. For the PA-E3 or PA-T3, the show controllers serial command also displays configuration information such as the framing, clock source, bandwidth limit, whether scrambling is enabled, the national bit, the international bits, and DSU mode configured on the interface. Also displayed is the performance statistics for the current interval and last 15-minute interval and whether any alarms exist.

Table 22 describes the show controllers t1 display fields.
| 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 (OOF) 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 | A Degraded Minute is one in which the estimated error rate exceeds 1E-6 but does not exceed 1E-3. |
Errored Secs | In ESF and E1-CRC links, an Errored Second is a second in which one of the following are detected: one or more Path Code Violations; one or more Out of Frame defects; one or more Controlled Slip events; a detected AIS defect. For D4 and E1-noCRC links, the presence of Bipolar Violations also triggers an Errored Second. |
Bursty Err Secs | A second with fewer than 320 and more than 1 Path Coding Violation error, no Severely Errored Frame defects and no detected incoming AIS defects. Controlled slips are not included in this parameter. |
Severely Err Secs | For ESF signals, a second with one of the following errors: 320 or more Path Code Violation errors; one or more Out of Frame defects; a detected AIS defect. For E1-CRC signals, a second with one of the following errors: 832 or more Path Code Violation errors; one or more Out of Frame defects. For E1-noCRC signals, a second with 2048 Line Code Violations or more. For D4 signals, a count of 1-second intervals with Framing Errors, or an Out of Frame defect, or 1544 Line Code Violations. |
Unavail Secs | A count of the total number of seconds on the interface. |
To display information about the Channelized T3 Interface Processor (CT3IP) on Cisco 7500 series routers, use the show controllers t3 privileged EXEC command.

Table 23 describes the show controllers t3 display fields.
| Field | Description |
|---|---|
T3 3/0/0 is up | T3 controller in slot 3 is operating. The controller's state can be up, down, administratively down. Loopback conditions are shown by (Locally looped) or (Remotely Looped). |
CT3 H/W Version | Version number of the hardware. |
CT3 ROM Version | Version number of the ROM. |
CT3 F/W Version | Version number of the firmware. |
Mx H/W version | Hardware version number of the HDLC controller chip. |
Mx ucode ver | Microcode version of the HDLC controller chip. |
Applique type | Controller type. |
No alarms detected | Any alarms detected by the controller are displayed here. Possible alarms are as follows:
|
MDL transmission is disabled | Status of the maintenance data link (either enabled or disabled). |
FEAC code received | Whether or not a far-end alarm code request is being received. Possible values are as follows:
|
Framing is M23 | Framing type on the CT3IP. Values are: M23, C-Bit, and Auto-detect. |
Line Code is B3ZS | Line coding format on the CT3IP. |
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:
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. |
Line Code Violations | Line Code Violations (LCV) is a count of both Bipolar Violations (BPVs) and Excessive Zeros (EXZs) occurring over the accumulation period. An EXZ increments the LCV by one regardless of the length of the zero string. |
P-bit Coding Violation | For all DS3 applications, a P-bit coding violation (PVC) error event is a 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. |
C-bit Coding Violation | For C-bit parity and SYNTRAN DS3 applications, the C-bit coding violation (CCV) is the 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. For SYNTRAN, it is a count of CRC-9 errors occurring in the accumulation interval. |
P-bit Err Secs | P-bit errored seconds (PES) is a second 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 | 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. |
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:
|
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 (OOF) 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. |
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 misconfigured. This counter can be used to help diagnose this situation. |
To display information about memory management and error counters on the Token Ring Interface Processor (TRIP) for the Cisco 7500 series, use the show controllers token privileged EXEC command.
show controllers tokenThis command has no arguments or keywords.
Privileged EXEC
This command first appeared in Cisco IOS Release 10.0.
The information was modified in Cisco IOS Release 11.3(3)T to include the PA-4R-FDX full-duplex Token Ring port adapter.
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 show controllers token 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.
Sample output for the show controllers token command on the Cisco 7500 follows:

To display information about the hub (repeater) on an Ethernet interface of a Cisco 2505 or Cisco 2507, use the show hub EXEC command.
show hub [ethernet number [port [end-port]]]
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, port numbers range from 1 through 8. On the Cisco 2507, 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. |
EXEC
This command first appeared in Cisco IOS Release 10.3.
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) by default. Therefore, the commands show hub, show hub ethernet 0, and show hub ethernet 0 1 16 all 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.
The following is sample output from the show hub command for hub 0, port 2 only:
Router# show hub ethernet 0 2

Table 25 describes significant fields shown in the display.
| Field | Description |
|---|---|
Port ... of ... is administratively down | Port number out of total ports; indicates whether the interface hardware is currently active, or down due to the following:
|
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 bytes 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 74-82 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 480-565 bit times in the frame. |
very long | Counter for the number of times the transmitter is active in excess of 4 ms to 7.5 ms. |
rate mismatches | Counter for the number of occurrences when the frequency, or data rate of incoming signal is noticably 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. |
