Default Values in SRP Mode for the Cisco OC-48 DPT⁄POS Interface Module
Table 3 lists default values for the Cisco OC-48 DPT⁄POS interface module in SRP mode. The table includes the command used for modifying a default value and indicates whether a value needs to be the same (or opposite) on the remote end of the connection.
For additional command information, refer to additional POS topics in this document and to the Cisco IOS CMTS Cable Command Referenc Guide.
Configuring the Cisco OC-48 DPT⁄POS Interface Modules for SRP
The following procedure is for creating a basic configuration, enabling an SRP interface, and specifying IP routing. You might also need to enter other configuration commands depending on the requirements of your system configuration.
The Cisco uBR10012 router identifies an SRP interface address by its line-card slot number and port number, in the format slot/port. For example, the slot/port address of an SRP interface on a Cisco OC-48 DPT⁄POS interface module installed in line card slot 3, subslot 0 and port 0 is 3/0/0.
Note
When two Cisco OC-48 POS/DPT interface modules are to be configured for SRP mode, they must be inserted in slot pairs (1 and 2) or (3 and 4). The line cards are referenced as side A and side B. One interface exists for the two line cards and the layer. The SRP protocol determines which line card on which the interface transmits data, and this is dependent upon the ring topology. The interface resides on the lower slot of the SRP line card pair. Therefore, all configuration commands are referenced using the lower slot number.
Note
Perform the following steps to configure two Cisco OC-48 DPT⁄POS interface modules in slot 3 and slot 4 of a Cisco uBR10012 router for the first time.

Configuring the Interface to Support SRP
The following procedure is for creating a basic configuration—enabling an interface and specifying IP routing. You might also need to enter other configuration commands, depending on the requirements of your system configuration.
A Cisco uBR10012 router identifies an interface address by its line-card slot number and port number, in the format slot/port. For example, the slot/port address of an interface on a Cisco OC-48 DPT⁄POS interface module installed in line card slot 1 and chassis port 0 is 1/0. Even though the card contains only one port, you must use the slot/port notation.
Use the configure terminal command to enter the configuration mode if you want to change the default configuration values on the Cisco OC-48 DPT⁄POS interface module. Be prepared with the information you will need, such as the IP address (see Table 3).
Use the following procedure to configure the Cisco OC-48 DPT⁄POS interface module. Press the Return key after each configuration step, unless otherwise noted.

Example:Router(config)# interface srp 3/0/0Router(config-if)#
Specifies the new interface to configure, followed by interface type (srp), and slot/subslot/port (line card slot number/subslot number/port number).
Step 7
ip address ip-address mask
Example:Router(config-if)# ip address 10.0.0.1 255.255.255.0Router(config-if)#Assigns an IP address and subnet mask to the SRP interface.
Step 8

Router(config-if)#
Router(config-if)# srp clock-source line b
Router(config-if)#
Verifies that the default value for the clock source is correct, where n is the source line.
The default setting is clock source internal. Typically, when two Cisco uBR10012 routers are connected back to back, or are connected over dark fiber, where no external clocking is available, set the clock source on each device to internal. If a router is connected to a SONET/SDH add/drop multiplexer (ADM), configure the clock-source for the clock source line on side A and side B.

Note
Step 12
srp tx-traffic-rate
Example:Router1(config-if)# srp tx-traffic-rate high 622Router1(config-if)# srp tx-traffic-rate low 1866Defines the amount of high and low priority traffic a node can transmit onto the SRP ring. For additional command syntax information, refer to the srp TX-traffic-rate command reference section.
Step 13
srp priority-map transmit
Example:Router1(config-if)# srp priority-map transmit 5Router1(config-if)#Controls which IP packets get queued in the high and low priority transmit queues, with precedence values of 5 to 7 to be queued in the high priority transmit queue, and precendence values of 0 to 4 to be queued in the low priority transmit queue.
The no form of this command removes the tx-traffic-rate from the configuration.
Step 14
srp priority-map transmit value
Example:Router(config-if)# srp priority-map transmit 5Maps SRP packets to a specific SRP priority (greater than or equal to the value setting to the high priority queue).

Example:Router# copy running-config startup-config[OK]Router#Writes the new configuration to nonvolatile random access memory (NVRAM).
The system displays an OK message when the configuration has been stored.
Configuring the SRP IPS Command Options
This section explains how to use srp ips command options to insert switches or remove automatic and user-configured switches:
•
•
Note
For example, you can enter a forced-switch command to force data traffic to one side of the ring when a Cisco OC-48 DPT⁄POS interface module is removed from a router slot, or in response to an event. Table 4 provides an explanation of the SRP IPS requests in the order of priority, from highest to lowest.
If a protection switch is requested for a given span on the ring, the node that receives the protection request issues a protection request to the node on the other end of the span using both the short path over the failed span, as the failure may be unidirectional, and the long path, around the ring.
As the protection requests travel around the ring, the protection hierarchy is applied. For example, if a high-priority signal fail (SF) request enters the ring, it overrides a pre-existing lower-priority signal degrade (SD) request. If an event or a user-configured command enters a low-priority request, it is not allowed if a high-priority request is present on the ring.
Note
All protection switches are performed bidirectionally and enter wraps at both ends of a span for transmit and receive directions, even if a failure is only unidirectional.
To enter user-configured SRP IPS requests when they are needed, perform the following steps.

DETAILED STEPS
Step 1
enable
Example:Router> enable
Enables privileged EXEC mode.
•
Step 2
configure terminal
Example:Router# configure terminal
Enters global configuration mode.
Step 3
sdcc enable
Example:Router(config)# sdcc enable
.
.
.
You must first enable the SDCC interface configuration mode before attempting to configure any SDCC commands. The sdcc enable command enables SDCC configuration on the router in global configuration mode. The default setting is disabled.
Caution
Refer to the "sdcc enable" section for complete command information and example.
Step 4
interface sdcc slot/subslot/port
then
no shutdown
Example:Router(config)# interface sdcc 8/0/0Router (config-if)# no shutdownTo administratively enable an SDCC interface, use the no shutdown command from the interface configuration prompt for the specified interface. The default state of an SDCC interface is adminstratively up.
Step 5
interface sdcc slot/subslot/port
Example:Router(config)# interface sdcc 2/0/0Router(config-if)#Prepares for SDCC interface configuration by selecting an interface, where slot is 1 to 4, subslot is 0, and port is 0.
Step 6
loopback
[no] loopbackExample:Router(config-if)# loopbackConfigures an SDCC interface for an internal loopback test in interface configuration mode. With an internal loopback, packets that are received by the line card from the Route Processor are looped back to the Route Processor without being sent to the line.
Use the no form of the command to stop the loopback test.
The default setting is none.
Step 7
crc { 16 | 32 }
Example:Router(config-if)# crc 16Configures the CRC size for HDLC encapsulation on an SDCC interface to 16 or 32 bits. For command syntax information and configuration examples, refer to the crc command reference section.
•
•
Step 8
mtu mtu bytes
Example:Router(config-if)# mtu 1000
Configures the Maximum Transmission Unit (MTU) that a particular interface can handle (in bytes). The default setting is 1500.
Note
For additional command syntax information and configuration examples, refer to the mtu command reference section.
Step 9
hold-queue number in
Example:Router(config-if)# hold-queue 60 in
Configures a hold queue on an SDCC interface for packets received from the line. For additional command syntax information and configuration examples, refer to the hold-queue command reference section.
Step 10
Ctrl-Z
Example:Router(config-if)# ^ZWhen you have included all of the configuration commands to complete the configuration, enter ^Z (press the Control key while you press Z) to exit configuration mode.
Step 11
show interface sdcc slot/subslot/port
Example:Router# show interface sdcc2/0/0
SDCC2/0/0 is up, line protocol is up
Verifies an SDCC interface configuration on a Cisco uBR10012 router.
For additional display information about the show interface sdcc command, refer to the "show interface sdcc" section.

card
To preprovision a slot in the Cisco uBR10012 router for a particular interface card, so that you can configure the interface without it being physically present in the slot, use the card command in global configuration mode. To remove the preprovisioning for a card, so that the physical slot reports being empty, use the no form of this command.
card slot/port {1cable-mc16c | 1cable-mc16e | 1gigethernet-1 | 1oc12pos-1 | 2cable-mc28bnc | 2cable-mc28c | 2oc12srp-sm-lr}
no card slot/port
Syntax Description
Note
Defaults
An empty card slot is not preprovisioned and cannot be configured or displayed.
Command Modes
Global configuration mode
Command History
Usage Guidelines
This command preprovisions a slot in the Cisco uBR10012 router to accept a particular line card, so that you can configure the interface without the card being physically present in the chassis. This command allows system administrators to plan for future configurations, without having to wait for the physical hardware to first arrive. When the line card does arrive, the installer can bring the card online by inserting the card into the chassis and connecting the necessary cables, without having to do any further configuration using the command-line interface.
The type of card must be appropriate for the slot being specified. Slots 1/0 through 4/0 are reserved for network uplink line cards. Slot 5/0 through 8/1 are reserved for cable interface line cards. Slot 0/0 is reserved for the FastEthernet interface on the PRE1 module and cannot be specified in this command.
Tip
Examples
The following example shows a list of supported card types for Cisco IOS Release 12.2(8)BC1, and then shows that slot 8/0 is being preprovisioned for a Cisco uBR-LCP2-MC28C cable interface line card. The cable interface for slot 8/0 can then be configured.

To assign values for specific elements of the SONET frame header and corresponding overhead, use the pos flag command in interface configuration mode. This command is typically used to meet a standards requirement or to ensure interoperability with another vendor's equipment. To restore the default values, use the no form of this command.
pos flag [c2 value] [j0 value] [s1s0 value]
[no] pos flag [c2 value] [j0 value] [s1s0 value]
Syntax Description
Defaults
The default values are as follows:

Command Modes
Interface configuration mode
Command History
Examples
In the following example, the c2 bit is set to 0xCF.
Router(config)# interface pos 4/0/02Router(config-if)# pos flag c2 0xCFpos framing
To set framing to SONET Optical Carrier (OC) or SDH STM, use the pos framing command in interface configuration mode. To restore the default framing mode, use the no form of the command.
pos framing [sdh | sonet]
[no] pos framing
Syntax Description
One difference between SONET and SDH framing is the value of the s0 and s1 bits (s is for size), which are bits 5 and 6 in SONET's H1 byte. SDH uses these bits to form the Administrative Unit (AU) field. The ITU-T G.709 standard (or G.707, which combines G.707, G.708, and G.709) describe the AU pointer. There are two major AU types, listed below:
•
•
The s1s0 bits or flag is unused in SONET. A transmitting POS interface configured with SONET framing sends ss = 00; a receiving SONET device ignores these bits, because they are used to indicate payload mapping type information—which is communicated using other fields. A POS interface configured with SDH framing typically sends ss = 10.
The following table illustrates well-known values for these bits.
00
SONET
11
Reserved
01
Used in older add/drop multiplexers (ADMs).
10
AU3/4. Most implementations in Europe use 3.
Defaults
The framing is set to SONET by default.
Command Modes
Interface configuration mode
Command History
Examples
In the following example, the framing type is set to SONET:
Router(config)# interface pos 5/0/1Router(config-if)# no pos framingpos report
To permit console logging of selected SONET alarms, use the pos report command in interface configuration mode.
pos report {b1-tca | b2-tca | b3-tca | lais | lrdi | pais | plop | prdi | plm-p | sd-ber | sf-ber | slof |
slos | uneq-p}Syntax Description
The alarms are as follows:
Defaults
The following errors are reported by default:
•
•
•
•
•
•
Command Modes
Interface configuration mode
Command History
Usage Guidelines
Reporting an alarm means that the alarm can be logged to the console. Just because an alarm is permitted to be logged does not guarantee that it is logged. SONET alarm hierarchy rules dictate that only the most severe alarm of an alarm group is reported. Whether an alarm is reported or not, you can view the current state of a defect by checking the "Active Defects" line from the show controller pos command output. A defect is a problem indication that is a candidate for an alarm.
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.
PAIS is sent by line terminating equipment (LTE) to alert the downstream path terminating equipment (PTE) that it has detected a defect on its incoming line signal.
PLOP is reported as a result of an invalid pointer (H1, H2) or an excess number of new data flag (NDF) enabled indications.
SLOF is detected when a severely error framing (SEF) defect on the incoming SONET signal persists for 3 milliseconds.
SLOS 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.
To determine the alarms that are reported on the interface, use the show controllers pos command.
Examples
The following example enables reporting of SD-BER and LAIS alarms on the interface:
Router(config)# interface pos 3/0/0Router(config-if)# pos report sd-berRouter(config-if)# pos report laisRouter(config-if)# endRouter#Related Commands
interface
Defines the IP addresses of the server, configures an interface type, and enters interface configuration mode.
Displays information about the POS controllers.
pos scramble-atm
To enable SONET payload scrambling, use the pos scramble-atm command in interface configuration mode. To disable SONET payload scrambling, use the no form of this command.
pos scramble-atm
no pos scramble-atm
Syntax Description
This command has no additional keywords or arguments.
Defaults
POS scrambling is disabled by default.
Command Modes

Examples
To enable SONET payload scrambling, use the following command sequence:
Router(config)# interface pos 3/0/0Router(config-if)# pos scramble-atmRouter(config-if)# no shutdownRouter(config-if)# endTo verify that SONET payload scrambling is enabled on an interface, enter the show running-config command. If scrambling is enabled, the following line is displayed in the interface configuration:
pos scramble-atmpos threshold
To set the bit error rate (BER) threshold values of the specified alarms for a POS interface, use the pos threshold command in interface configuration mode. To return to the default setting, use the no form of this command.

Usage Guidelines
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.
SF-BER and SD-BER are sourced from B2 BIP-8 error counts (as is B2-TCA). However, SF-BER and SD-BER feed into the APS machine and can lead to a protection switch (if APS is configured).
B1-TCA, B2-TCA, and B3-TCA do nothing more than print a log message to the console (if reports for them are enabled).
To determine the BER thresholds configured on the interface, use the show controllers pos command.
Examples
The following example configures thresholds on the interface:
Router(config)# interface pos 3/0/0Router(config-if)# pos threshold sd-ber 8Router(config-if)# pos threshold sf-ber 4Router(config-if)# pos threshold b1_tca 4Router(config-if)# endRouter#The following example returns the POS sf-ber threshold back to the default (of 3).
Router(config-if)# pos threshold b1-tca sf-ber 3sdcc enable
To enable SDCC before configuring additional SDCC interface settings, use the sdcc enable command in global configuration mode. To disable SDCC mode on the interface and to remove the SDCC interface from the interface list in the configuration, use the no form of this command.

srp ips wtr-timer value
no srp ips wtr-timer
Syntax Description
Defaults
The timer is set to 60 seconds by default.
Command Modes
Interface configuration mode
Command History
Usage Guidelines
When the cause of a wrap is removed, the wrap remains in place for a length of time determined by the SRP wait-to-restore timer. This mechanism prevents oscillations on the SRP ring. Cisco recommends that the srp ips wrt-timer command value be the same for all nodes on a ring. Therefore, if one node's srp ips wrt-timer command value is changed, the value for all other nodes on a ring should change to the same value.
Examples
The following example shows how to use the srp ips wtr-timer command to change the SRP IPS wait-to-restore timer to 10 seconds on SRP interface 1/0/0:
Router# configure terminalRouter(config)# interface srp 1/0/0Router(config-if)# srp ips wtr-timer 10Router(config-if)# endsrp loopback
To configure the framer into loopback mode, use the srp loopback command in interface configuration mode. To restore the default value, use the no form of this command.
srp loopback [internal | line] [a | b]
no srp loopback [internal | line] [a | b]
Syntax Description
Defaults
No loopbacks are in place by default.
Command Modes
Interface configuration mode
Command History
Usage Guidelines
Using the srp loopback command breaks connectivity. This command is used mostly during the initial setup of the SONET link (such as a node-to-node fiber connection), or when general connectivity is not clearly and obviously achieved. You can also use the srp loopback command when fiber or equipment connections are rearranged, or if new connectivity problems arise. If a node (side A or side B) is not specified in the command, the loopback value is applied to both sides.
Examples
The following example shows how to enter the srp loopback command on side A:
Router# configure terminalRouter(config)# interface srp 1/0/0Router(config-if)# srp loopback line aRouter(config-if)#srp priority-map
To set priority mapping for transmitting and receiving packets, use the srp priority-map command in global configuration mode. To disable priority mapping, use the no form of this command.
srp priority-map {transmit} value
no srp priority-map
Syntax Description
transmit
Transmits priority mapping for high priority traffic.
value
Minimum SRP transmit priority. Valid range is 1-7.
Defaults
No default behavior or values.
Command Modes
Interface configuration mode
Command History
Usage Guidelines
The SRP interface provides commands to enforce quality of service (QoS) functionality on the transmit side of Cisco uBR10012 router. SRP uses the IP type-of-service (ToS) field values to determine packet priority.
The SRP interface classifies traffic on the transmit side into high- and low-priority traffic. You have the option to configure high- or low-priority traffic and can rate limit the high-priority traffic.
The srp priority-map transmit command enables users to specify SRP packets with SRP priority. Anything above the specified value is considered high-priority traffic.
Examples
The following example shows how to configure the Cisco uBR10012 router to transmit packets with priority greater than 5 as high priority packets:
Router(config-if)# srp priority-map transmit 5srp shutdown
To shut down an interface by entering a forced-switch, use the srp shutdown command in interface configuration mode. To remove the forced-switch wrap near the interface, use the no form of this command .
srp shutdown [a | b]
no srp shutdown [a | b]
Syntax Description
a
Side of a node that has outer ring receive fiber identified as side A.
b
Side of a node that has inner ring receive fiber identified as side B.
Defaults
The default is SRP protocol enabled.
Command Modes
Interface configuration mode
Command History
Usage Guidelines
This srp shutdown command is an abbreviated form of the srp ips request forced-switch command in interface configuration mode that enters a forced-switch request and inserts a wrap on a ring. To remove the wrap on the ring, Use the no form of this command. The long form, srp ips request forced-switch, appears in the show command output.
Note
srp shutdown inserts a forced-switch wrap on a ring, while shutdown invokes the pass-through mode, logically removing the interface from the ring.
Examples
The following example shows how to enter a Spatial Reuse Protocol (SRP) shutdown request on side A of an SRP interface:
Router# configure terminalRouter(config)# interface srp 1/0/0Router(config-if)# srp shutdown aRouter(config-if)#srp topology-timer
To specify the frequency of the Spatial Reuse Protocol (SRP) topology timer, use the srp topology-timer command in interface configuration mode. Use the no form of this command to restore the default value of 10 seconds.
srp topology-timer value
no srp topology-timer
Syntax Description
Defaults
The timer is set to 10 seconds by default.
Command Modes
Interface configuration mode
Command History
Usage Guidelines
The srp topology-timer command in interface configuration mode and a specified value determine how frequently topology discovery messages are sent around the ring to identify the current nodes on the SRP ring. Cisco recommends that the srp topology-timer value be the same for all nodes on a ring. Therefore, if one node's topology-timer value is changed, the value for all other nodes on a ring should be changed to the same value.
Examples
The following example shows how to set the frequency for how often SRP topology packets are sent around the ring to identify the nodes:
Router# configure terminalRouter(config)# interface srp 1/0/0Router(config-if)# srp topology-timer 100Router(config-if)#srp TX-traffic-rate
To configure the amount of high- and low-priority traffic being transmitted from the router onto the Spatial Reuse Protocol (SRP) ring, use the srp TX-traffic-rate command in interface configuration mode. To remove the TX-traffic-rate from the configuration, use the no form of this command.
srp TX-traffic-rate [high | low] Mbps
no srp TX-traffic-rate [high | low] Mbps
Syntax Description
Mbps
Average rate in Mbps. OC-48 DPT line card values must be in increments of 1 Mbps in the range of 1 to 2488. The range for OC-192 DPT line cards is from 1 to 9952.
Defaults
By default, TX-traffic-rate is disabled on low priority and set to 20 Mbps for high priority.
Command Modes
Interface configuration mode
Command History
Usage Guidelines
Use this command to control the amount of high- and low-priority traffic a node can transmit onto the SRP ring. This command does not control the amount of transit traffic on the ring, which is controlled by the SRP fairness algorithm.
Note
Examples
The following example limits the rate of high-priority traffic transmitted on the ring to an average rate of 622 Mbps (25 percent line bandwidth) and low-priority traffic transmitted on the ring to an average rate of 1866 Mbps (75 percent line bandwidth):
Router# configure terminalRouter(config)# interface srp 1/0/0Router(config-if)# srp rate-limit hi 622Router(config-if)# srp rate-limit low 1866Router(config-if)# endRouter#Cisco OC-48 DPT⁄POS Interface Module System Messages
