This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.
Usage Guidelines
Configuring
B8ZS
is a method of ensuring the ones density requirement on a T1 line by substituting intentional bipolar violations in bit positions four and seven for a sequence of eight zero bits. When the CSU/DSU is configured for AMI, you must guarantee the ones density requirement in your router configuration using the service-modulet1data-codinginverted command or the service-modulet1timeslotsspeed56command.
Your T1 service provider determines which line code, either amior b8zs, is required for your T1 circuit.
Examples
The following example specifies AMI as the line code:
Router(config)# interface serial 0
Router(config
-if)
# service-module t1 linecode ami

12.2SX
This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.
Usage Guidelines
Remote alarms are transmitted by the CSU/DSU when it detects an alarm condition, such as a red alarm (loss of frame) or blue alarm (unframed ones). The receiving CSU/DSU then knows that there is an error condition on the line.
With D4 Super Frame configured, a remote alarm condition is transmitted by setting the bit 2 of each time slot to zero. For received user data that has the bit 2 of each time slot set to zero, the CSU/DSU interprets the data as a remote alarm and interrupts data transmission, which explains why remote alarms are disabled by default. With Extended Super Frame configured, the remote alarm condition is signalled out of band in the facilities data link.
You can see if the FT1/T1 CSU/DSU is receiving a remote alarm (yellow alarm) by issuing the showservice-moduleserial command.
Examples
The following example enables remote alarm generation and detection:
Router(config)# interface serial 0
Router(config
-if)
# service-module t1 remote-alarm-enable

no form of this command.
service-modulet1remote-loopback
{ full | payloadv54 }
noservice-modulet1remote-loopback
{ full | payloadv54 }
Syntax Description
full
Configures the remote loopback code used to transmit or accept CSU loopback requests.
payload
Configures the loopback code used by the local CSU/DSU to generate or detect payload-loopback commands.
v54
Industry standard loopback code. Use this keyword for CSU/DSUs that may not support the Accunet loopup standards. This keyword is used only with a payload request, not a full request.
Use the
fullkeyword to enable the standard loopup codes, which use a 1-in-5 pattern for loopup and a 1-in-3 pattern for loopdown. Use the

This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.
Usage Guidelines
The
no form of this command disables loopback requests. For example, the
noservice-modulet1remote-loopbackfull command ignores all full-bandwidth loopback transmissions and requests.
Configuring the
no form of the command might not prevent telco line providers from looping your router in extended super frame (esf) mode because fractional T1/T1 lines use facilities data link messages to initiate loopbacks.
To have the loopback remote commands on the FT1/T1 CSU/DSU module function successfully, you need to enable the
service-modulet1remote-loopback command.
Note
Use the
fullkeyword to enable the standard loopup codes, which use a 1-in-5 pattern for loopup and a 1-in-3 pattern for loopdown. Use the
payloadv54keywords to enable the v54 pseudorandom codes for loopup and v54 pseudorandom codes for loopdown.
Examples
The following example shows how to configure two routers connected back-to-back through a fractional T1/T1 line to enter loopback mode:
Router(config)# interface serial 0/0
Router(config-if)# service-module t1 remote-loopback full
Router(config-if)# loopback remote full

This command was introduced for wireless-enabled Cisco 880 Series and Cisco 890 Series Integrated Services Routers.
Usage Guidelines
When running the advanced IP services feature set on either Cisco 880 Series routers or Cisco 890 Series routers, use the
service-modulewlan-ap0bootimageunifiedcommandto enable the Cisco unified software upgrade image on the embedded wireless access point. After enabling the unified image, use the
service-modulewlan-ap0reload command to perform a graceful shutdown and reboot of the access point.
Note
The
service-modulewlan-ap0bootimagecommand does not support recovery images on the embedded access point. Use the
service-modulewlan-ap0reload command to shutdown and reboot the access point.
Cisco 880 Series and Cisco 890 Series routers with embedded access point running the unified software image require DHCP to obtain an IP address for the access point. An IP address is needed to communicate with the Wireless LAN Controller (WLC) and to download its image upon boot up. The host router can provide DHCP server functionality through the DHCP pool to reach the WLC, and setup option 43 for the controller IP address in the DHCP pool configuration.
Use the following guideline to setup a DHCP pool on the host router.
ip dhcp pool embedded-ap-pool
network 60.0.0.0 255.255.255.0
default router 60.0.0.1
option 43 hex f104.0a0a.0a0f /* Single WLC IP address (10.10.10.15) in HEX format */

12.2SX
This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.
Usage Guidelines
Using Path MTU Discovery (PMTUD) you can determine an MTU value for IP packets that avoids fragmentation. If ICMP messages are blocked by a router, the path MTU is broken and packets with the DF bit set are discarded. Use the setipdf command to clear the DF bit and allow the packet to be fragmented and sent. Fragmentation can slow the speed of packet forwarding on the network but access lists can be used to limit the number of packets on which the DF bit will be cleared.
Note
Some IP transmitters (notably some versions of Linux) may set the identification field in the
IP header (IPid) to zero when the DF bit is set. If the router should clear the DF bit on such a packet
and if that packet should subsequently be fragmented, then the IP receiver will probably be unable
to correctly reassemble the original IP packet.
Examples
The following example shows how to clear the DF bit to allow fragmentation. In this example a router is blocking ICMP messages and breaking the path MTU. Using policy routing both the inbound and outbound packets on interface serial 0 will have their DF bit set to 0 which allows fragmentation.
interface serial 0
ip policy route-map clear-df-bit
route-map clear-df-bit permit 10

12.2SX
This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.
Usage Guidelines
The shelf number is used to distinguish between cards on the router shelf and cards on the dial shelf.
Caution
You must reload the Cisco AS5800 for the shelf number to take effect. The shelf numbers are part of the interface names. When you reload the Cisco AS5800, all NVRAM interface configuration information is lost.
You can specify the shelf number through the setup facility during initial configuration of the
Cisco AS5800. This is the recommended method to specify shelf numbers.
To display the shelf numbers, use the showrunning-config command. If a shelf number has been changed, the pending change is shown in the output of the showversion command (for example, the dial-shelf ID is 87; will change to 2 on reload).

Usage Guidelines
This command displays the types and status of cards installed in a Cisco 7304 router (such as network services engines [NSEs], RPs, line cards, MSCs, and SPAs), and information about incompatible FPGA images. When the bundled and current FPGA images are compatible, they are not displayed.
This command also displays whether your system is in compliance with line card configuration guidelines. For NSEs and line cards, empty slots are not displayed in the output. However, for SPAs, several status values are reported, including an empty subslot, which is reported as “missing.”
If your system contains an unsupported line card or RP with no matching bundled FPGA image in Cisco IOS software, then this command displays “None” instead of the bundled FPGA version number.
Use this command to display information about the status of the active and standby NSEs.

Slots that are not owned by an RSC are shown to be in the ignore state. The RSC from which the command is entered owns slots 0 to 5, but has configured for it all slots (0 to 5 and 8 to 13--all slots except those in which the RSCs are inserted). Entries for slots 8 and 10 show the designator “ignore.”

The table below describes the fields shown in the MAC destination address filtering table section of the display. This section is useful for verifying the multicast destination addresses that are in the TCAM table and permitted by the interface. This information is useful for Cisco Systems technical support personnel.
Table 30 show controllers Command Field Descriptions--MAC Destination Address Filtering Table Section
Field
Description
Table entries: Total, Used, Available
Total number of MAC destination address entries possible in the TCAM table for the interface, the number of table entries currently used by the interface, and the number of table entries that remain available.
The 4-Port 10/100 Fast Ethernet SPA supports a 512-entry MAC filtering table for each supported interface (2048 entries total on the card).
Index
Table entry identifier.
MAC destination address
MAC destination address (multicast) permitted by the interface and used in the TCAM lookup table for packet filtering.
The multicast MAC entries typically come from routing protocols [such as Open Shortest Path First (OSPF) and Enhanced IGRP (EIGRP)], and other protocols including the Hot Standby Router Protocol (HSRP).
When the router reloads, three addresses appear by default in the MAC filtering table: the unicast address of the local interface, the Ethernet broadcast address, and the Ethernet multicast address.
Mask
Mask for the corresponding destination address. The SPA uses the bits that are set in the mask to look up the address in the TCAM table.
The table below describes the fields shown in the VLAN filtering table section of the display. This section is useful for verifying the VLANs that are in the TCAM table and are permitted by the interface. This information is useful for Cisco Systems technical support personnel.
Table 31 show controllers Command Field Descriptions--VLAN Filtering Table Section
Field
Description
Number of VLANs configured on this interface
Number of VLANs that are configured on the interface.
If the number of VLANs configured on the interface is 1022 or less, then the VLAN filtering table also shows an index entry for every VLAN ID. The number of VLANs configured on the interface can be 0, while the number of used table entries reports 2, because the SPA always uses two entries to provide valid matching criteria for promiscuous mode and non-VLAN packets.
Table entries: Total, Used, Available
Total number of VLAN entries possible in the TCAM filtering table for the interface, the number of table entries currently used by the interface (two are always in use by default), and the number of table entries that remain available.
The 4-Port 10/100 Fast Ethernet SPA supports a 1024-entry VLAN filtering table for each supported interface (4096 entries total on the card).
Index
Table entry identifier.
VLAN identifier
Number of the VLAN. Two VLAN ID 0 entries always appear in the table and represent the local interface port for handling of promiscuous mode and non-VLAN packets.
Other VLAN entries appear in this table when VLANs are configured on the interface.
Enabled
Status of the VLAN ID for TCAM filtering, with the following possible values:
No--The entry is disabled for filtering.
Yes--The entry is enabled for filtering.
The TCAM filter uses the “first-match” rule to filter packets that the SPA receives against entries in the table. The matching assessment begins at the top of the table with the VLAN ID 0 entries.
Note
The SPA always supports two VLAN ID 0 entries. The first VLAN ID 0 entry of the TCAM table is used for promiscuous mode. It has a value of “No,” meaning it is disabled, whenever promiscuous mode is disabled for the interface. The second VLAN ID 0 entry is used for filtering of non-VLAN packets.
Tunnel
Status of tunneling for the interface, with the following possible values:
No--Tunneling is disabled and the SPA performs MAC destination address filtering.
Yes--Tunneling is enabled and the SPA does not perform MAC destination address filtering.
Note
If promiscuous mode is enabled, then the first VLAN ID 0 entry shows tunnel = Yes. All other VLAN ID entries show tunnel = No.

The following table describes the fields shown in the MAC destination address filtering table section of the display. This section is useful for verifying the multicast destination addresses that are in the TCAM table and permitted by the interface. This information is useful for Cisco Systems technical support personnel.
Table 38 show controllers Command Field Descriptions--MAC Destination Address Filtering Table Section
Field
Description
Table entries: Total, Used
Total number of MAC destination address entries possible in the TCAM table for the interface, and the number of table entries currently used by the interface.
The 2-Port 10/100/1000 Gigabit Ethernet SPA supports a 512-entry MAC filtering table for each supported interface (1024 entries total on the card).
Index
Table entry identifier.
MAC destination address
MAC destination address (multicast) permitted by the interface and used in the TCAM lookup table for packet filtering.
The multicast MAC entries typically come from routing protocols [such as Open Shortest Path First (OSPF) and Enhanced IGRP (EIGRP)], and other protocols including the Hot Standby Router Protocol (HSRP).
When the router reloads, three addresses appear by default in the MAC filtering table: the unicast address of the local interface, the Ethernet broadcast address, and the Ethernet multicast address.
Mask
Mask for the corresponding destination address. The SPA uses the bits that are set in the mask to look up the address in the TCAM table.
The following table describes the fields shown in the VLAN filtering table section of the display. This section is useful for verifying the VLANs that are in the TCAM table and are permitted by the interface. This information is useful for Cisco Systems technical support personnel.
Table 39 show controllers Command Field Descriptions--VLAN Filtering Table Section
Field
Description
Number of VLANs configured on this interface
Number of VLANs that are configured on the interface.
If the number of VLANs configured on the interface is 1022 or less, then the VLAN filtering table also shows an index entry for every VLAN ID. The number of VLANs configured on the interface can be 0, while the number of used table entries reports 2, because the SPA always uses two entries to provide valid matching criteria for promiscuous mode and non-VLAN packets.
Table entries: Total, Used, Available
Total number of VLAN entries possible in the TCAM filtering table for the interface, the number of table entries currently used by the interface (two are always in use by default), and the number of table entries that remain available.
The 2-Port 10/100/1000 Gigabit Ethernet SPA supports a 1024-entry VLAN filtering table for each supported interface (2048 entries total on the card).
Index
Table entry identifier.
VLAN identifier
Number of the VLAN. Two VLAN ID 0 entries always appear in the table and represent the local interface port for handling of promiscuous mode and non-VLAN packets.
Other VLAN entries appear in this table when VLANs are configured on the interface.
Enabled
Status of the VLAN ID for TCAM filtering, with the following possible values:
No--The entry is disabled for filtering.
Yes--The entry is enabled for filtering.
The TCAM filter uses the “first-match” rule to filter packets that the SPA receives against entries in the table. The matching assessment begins at the top of the table with the VLAN ID 0 entries.
Note
The SPA always supports two VLAN ID 0 entries. The first VLAN ID 0 entry of the TCAM table is used for promiscuous mode. It has a value of “No,” meaning it is disabled, whenever promiscuous mode is disabled for the interface. The second VLAN ID 0 entry is used for filtering of non-VLAN packets.
Tunnel
Status of tunneling for the interface, with the following possible values:
No--Tunneling is disabled and theSPA performs MAC destination address filtering.
Yes--Tunneling is enabled and the SPA does not perform MAC destination address filtering.
Note
If promiscuous mode is enabled, then the first VLAN ID 0 entry shows tunnel = Yes. All other VLAN ID entries show tunnel = No.
The following table describes the fields shown in the platform details section of the display.

12.2(33)SRA
This command was integrated into Cisco IOS Release 12.2(33)SRA.
12.2SX
This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.
Usage Guidelines
This command displays information that the system uses for bridging and routing that is specific to the interface hardware. The information displayed is generally useful for diagnostic tasks performed by technical support personnel.
The interface type is queried only at startup. If the hardware changes
subsequent to initial startup, 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, the display presented for the
showinterfaces command incorrectly reports attachment to a DTE device although the software recognizes the DCE interface and behaves accordingly.

Table 45 show controllers pos Field Descriptions
Field
Description
POSx/y/z
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
posreport 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 and 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
posthreshold interface command.
TCA thresholds
List of the threshold crossing alarms (TCAs) that you configured with theposthreshold interface command.
