service-module t1 linecode

To select the line code for the fractional T1/T1 module, use the service-module t1 linecode command in interface configuration mode. To select the default, the B8ZS line code, use the no form of this command.

service-module t1 linecode {ami | b8zs}

no service-module t1 linecode {ami | b8zs}

Syntax Description

ami	Specifies alternate mark inversion (AMI) as the line code.
b8zs	Specifies binary 8 zero substitution (B8ZS) as the line code. This is the default.

Defaults

The default line code is B8ZS.

Command Modes

Interface configuration

Command History

Release	Modification
11.2	This command was introduced.
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

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-module t1 data-coding inverted command or the service-module t1 time slots speed 56 command.

Your T1 service provider determines which line code, either ami or 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

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 timeslots	Defines time slots that constitute a fractional T1/T1 (FT1/T1) channel.

service-module t1 remote-alarm-enable

To generate remote alarms (yellow alarms) at the local CSU/DSU or detect remote alarms sent from the remote CSU/DSU, use the service-module t1 remote-alarm-enable command in interface configuration mode. To disable remote alarms, use the no form of this command.

service-module t1 remote-alarm-enable

no service-module t1 remote-alarm-enable

Syntax Description

This command has no arguments or keywords.

Defaults

Remote alarms are disabled.

Command Modes

Interface configuration

Command History

Release	Modification
11.2	This command was introduced.
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

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 show service-module serial 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

Related Commands

Command	Description
service-module t1 framing	Selects the frame type for a line using the fractional T1/T1 (FT1/T1) module.
show service-module serial	Displays performance statistics for an integrated CSU/DSU.

service-module t1 remote-loopback

To specify that the fractional T1/T1 DSU/CSU module enters loopback mode when it receives a loopback code on the line, use the service-module t1 remote-loopback command in interface configuration mode. To disable remote loopbacks, use the no form of this command.

service-module t1 remote-loopback {full | payload v54}

no service-module t1 remote-loopback {full | payload v54

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 full keyword 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 payload v54 keywords to enable the v54 pseudo-random loopup codes for loopup and v54 pseudo-random loopdown codes for loopdown.

Defaults

Full and payload loopbacks with standard loopup codes

Command Modes

Interface configuration

Command History

Release	Modification
11.2	This command was introduced.
12.3(2)T	The provision for an alternate loopback code was removed.
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

The no form of this command disables loopback requests. For example, the no service-module t1 remote-loopback full 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-module t1 remote-loopback command.

---

Note Use the full keyword 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 payload v54 keywords 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

!

%SERVICE_MODULE-5-LOOPUPREMOTE: Unit Serial0/0 - Remote unit placed in loopback

Router(config-if)# no loopback remote

%SERVICE_MODULE-5-LOOPDOWNREMOTE: Unit Serial0/0 - Remote loopback test cancelled

The following example shows how to configure two routers connected back-to-back through a 
fractional T1/T1 line to enter loopback mode and generate or detect payload-loopback 
commands:

Router(config-if)# service-module t1 remote-loopback payload v54 

Router(config-if)# loopback remote payload

%%SERVICE_MODULE-5-LOOPUPREMOTE: Unit Serial0/0 - Remote unit placed in loopback

Related Commands

Command	Description
loopback remote (interface)	Loops packets through a DSU/CSU to a remote DSU/CSU and back over a channelized T1 link.

service-module t1 timeslots

To define time slots that constitute a fractional T1/T1 (FT1/T1) channel, use the service-module t1 timeslots command in interface configuration mode. To resume the default setting (all FT1/T1 time slots 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 time slots that constitute the FT1/T1 channel. The range is from 1 to 24, where the first time slot is numbered 1 and the last time slot is numbered 24. Specify this field by using a series of subranges separated by commas.
all	Selects all FT1/T1 time slots.
speed	(Optional) Specifies the time slot speed.
56	(Optional) 56 kbps.
64	(Optional) 64 kbps. This is the default.

Defaults

64 kbps is the default for all time slots.

Command Modes

Interface configuration

Command History

Release	Modification
11.2	This command was introduced.
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 specifies which time slots are used in fractional T1 operation and determines the amount of bandwidth available to the router in each FT1/T1 channel.

The time-slot range must match the time slots assigned to the channel group. Your service provider defines the time slots 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 time-slot ranges and a speed of 64 kbps:

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

service-module wlan-ap bootimage

To configure the boot image on the service module, use the service-module wlan-ap bootimage command in privileged EXEC mode.

service-module wlan-ap interface number bootimage [autonomous|unified]

Syntax Description

interface number	The interface number for the wireless device. Always use 0.
autonomous	Autonomous software image.
unified	Upgrade image with Lightweight Access Point Protocol (LWAPP).

Command Default

Autonomous software image

Command Modes

Privileged EXEC

Command History

Release	Modification
12.4(20) T	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-module wlan-ap 0 bootimage unified command to enable the Cisco unified software upgrade image on the embedded wireless access point. After enabling the unified image, use the service-module wlan-ap 0 reload command to perform a graceful shutdown and reboot of the access point.

---

Note The service-module wlan-ap 0 bootimage command does not support recovery images on the embedded access point. Use the service-module wlan-ap 0 reload 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 */

int vlan 1  /* Default Vlan */

ip address 60.0.0.1 255.255.255.0

int Wlan-GigabitEthernet0 /* internal switch-port to AP */

switchport access vlan 1

12.1(6)	This command was introduced.
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

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 set ip df 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

match ip address 111

set ip df 0

access-list 111 permit tcp any any

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.

Examples

The following example displays information about a Cisco 7304 router that has current FPGA images:

CEM	Displays the slot, port, and channel number of a CEM channel.
Current State	Displays the current state of a CEM channel. The state can be one of the following: •up—The channel is receiving valid packets from a source CEM channel. •down—The channel is receiving no packets (for example, the dejitter buffer is empty). •shutdown—The CEM channel has been administratively shut down.
Line State	Displays the current line state of a CEM channel. The line state can be one of the following: •up—The line is ready. •down—The line is down. A T1 or E1 line is down when the line is experiencing a physical-layer failure, such as loss of signal (LOS), loss of multiframe alignment (OOF), or alarm indication signal (AIS). A serial line is down when no cable is attached to the port.
Operational State	Displays the current operational state of a CEM channel. The operational state can be one of the following: •config-incomplete—The channel is in a config-incomplete state when any of the following conditions exist: –An xconnect is not defined. –A local IP address is not defined. –A local UDP port is not defined. –A remote UDP port is not defined. –The CEM channel is administratively shut down. •enabled—If none of the conditions for the config-incomplete state exists, but the CEM channel is receiving no packets from the remote side, the CEM channel is in an enabled state. •config-mismatch—If packets are arriving from the remote side but with a different payload size, data protection setting, or compression setting, the channel is in the config-mismatch state. •active—The CEM channel is active if none of the conditions outlined above exist.
Payload Size	Payload size configured for the CEM channel, in bytes.
Payload Compression	Displays whether payload compression is enabled or disabled for the CEM channel.
Data protection	Displays whether data protection is enabled or disabled for the CEM channel.
MAX_IPT	Maximum time between two consecutive ingress packets

You must enter this command from one of the route-switch-controller (RSC) cards.

Use the show chassis command to display additional output relevant to handover-split mode. Command output shows the RSC card to be configured with all slots of the entire chassis, regardless of configured ownership. Slots owned by the peer RSC are shown in the ignore state, properly configured and ready to go.

Examples

The following example shows output for a system in handover-split mode. Each RSC is shown to be configured with all slots in the entire chassis, regardless of whether the RSC actually owns the slot. 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."

Router# show chassis

Field	Description
E3 2/0 is down	The E3 controller in slot 0 shows the state in which it is operating. The controller's state can be up, down, or administratively down. Loopback conditions are shown by (Locally Looped) or (Remotely Looped).
Applique type	Controller type.
Description	User-specified information about the E3 controller.
No alarms detected (not shown in display)	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. •Receiver is getting AIS. •Receiver has loss of frame. •Receiver has remote alarm. •Receiver has no alarms.
Linecode is (not shown in display)	Line coding format on the E3.
Framing	Framing type.
Clock Source	User-specified clock source (Line or Internal).
Data in current interval (450 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.
PCV	Path coding violation (PCV) error event is a frame synchronization bit error in the E1-no-CRC formats or a cyclic redundancy check (CRC) error in the E1-CRC formats.
CCV	C-bit coding violation (CCV) error event for C-bit parity. This is the count of coding violations reported via the C-bits occurring in the accumulation interval.
PES	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.
PSES	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.
SEFS	Severely errored framing seconds (SEFS) is a second with one or more out-of-frame defects or a detected incoming AIS.
UAS	Unavailable seconds (UAS) are calculated by counting the number of seconds for which the interface is unavailable. For more information, refer to RFC 1407.
LES	Line errored seconds (LES) is a second in which one or more code violations or one or more LOS defects occurred.
CES	C-bit errored seconds (CES) is a second with one or more out-of-frame defects or a detected incoming AIS. This gauge is not incremented when UASs are counted.
CSES	C-bit severely errored seconds (CSES) is a second with one or more out-of-frame defects or a detected incoming AIS. This gauge is not incremented when UASs are counted.

---

Note None of the SPA SPI4 error counters appear in show controllers fastethernet command output until at least one of those types of SPI4 errors occurs.

---

All of the errors in the SPA error counters section are subject to the SPA automatic recovery process when certain thresholds are reached.

Table 44 show controllers Command Field Descriptions—SPA Error Counters Section 

Field	Description
SPI4 TX out of frame error = (hh:mm:ss ago)	Number of SPI4 out-of-frame errors (events) detected in the transmit direction (toward the network), from the MSC to the SPA FPGA device. The time stamp indicates how long ago (in hours:minutes:seconds) from the current system time, that the last error was detected. This error indicates a loss of synchronization between the synchronization block and the data received on the SPI4 path. When synchronization is reacquired, the error no longer occurs.
SPI4 TX Train valid error = (hh:mm:ss ago)	Number of times that a low-level synchronization problem was detected in the transmit direction (toward the network), from the MSC to the SPA FPGA device. The time stamp indicates how long ago (in hours:minutes:seconds) from the current system time, that the last error was detected.
SPI4 TX DIP4 error = (hh:mm:ss ago)	Number of 4-bit Diagonal Interleaved Parity (DIP4) errors in the transmit direction (toward the network), from the MSC to the SPA FPGA device. The time stamp indicates how long ago (in hours:minutes:seconds) from the current system time, that the last error was detected. DIP4 is a parity algorithm where a 4-bit odd parity is computed diagonally over control and data words.
SPI4 RX out of frame error = (hh:mm:ss ago)	Number of SPI4 out-of-frame errors (events) detected in the receive direction (from the network), from the SPA FPGA device to the MSC. The time stamp indicates how long ago (in hours:minutes:seconds) from the current system time, that the last error was detected. This error indicates a loss of synchronization between the synchronization block and the data received on the SPI4 path. When synchronization is reacquired, the error no longer occurs.
SPI4 RX DIP2 error = (hh:mm:ss ago)	Number of 2-bit Diagonal Interleaved Parity (DIP2) errors in the receive direction (from the network), from the SPA FPGA device to the MSC. The time stamp indicates how long ago (in hours:minutes:seconds) from the current system time, that the last error was detected. DIP2 is a parity algorithm where a 2-bit odd parity is computed diagonally over status words.

Table 45 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 45 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.

Table 46 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 46 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.

Table 47 describes the fields shown in the Platform details section of the display.

Table 47 show controllers Command Field Descriptions—Platform Details Section 

Field	Description
PXF tif number	Number of the interface (in hexadecimal format) used for PXF on the network services engine (NSE) or by the Hyper Transport (HT) FPGA device on the network processing engine (NPE).
