Product Part Numbers: UBR10-SRP-OC48SMS, UBR10-SRP-OC48SML, ESR10C48/P/SRPSMS, ESR10C48/P/SRPSML
April, 2009

This document describes procedures and Cisco IOS commands for configuring and monitoring the Cisco OC-48 DPT⁄POS interface module on the Cisco uBR10012 router.

The Cisco OC-48 DPT⁄POS interface module is a dual-mode module, providing interface support for Packet over SONET (POS) or Spatial Reuse Protocol (SRP).


Note The Cisco OC-48 DPT⁄POS interface module supports SONET Section Data Communications Channel (SDCC) in either POS or SRP modes.


Packet-over-SONET (POS) technology is ideally suited for Internet and IP networks, because it provides superior bandwidth utilization efficiency over other transport methods. POS can support a single connection or redundant connections to provide a robust, high-speed, high-throughput transport for IP traffic.

Spatial Reuse Protocol (SRP) is the media-independent Media Access Control (MAC)-layer protocol that enables Cisco Dynamic Packet Transport (DPT) functionality in ring configurations. The SRP MAC protocol provides the base functionality for addressing, packet stripping, bandwidth control, and control message propagation on the packet ring.

Prerequisites for Configuring the Cisco uBR10012 OC-48 DPT/POS Interface Module

The Cisco uBR10012 router should be operational before beginning the configuration procedures in this document. The configuration of the Cisco OC-48 DPT⁄POS interface module requires that the following conditions be met:

The Cisco uBR10012 router must be running Cisco IOS release 12.2(11)BC3 or a later release to support the Cisco OC-48 DPT⁄POS interface module.

The Cisco uBR10012 router must be using one or two PRE1 or PRE2 processor modules to support the Cisco OC-48 DPT⁄POS interface module. The original PRE module for the Cisco uBR10012 router is not supportedwith the Cisco OC-48 DPT⁄POS interface module.

At least one Timing, Communication, and Control Plus (TCC+) card must be installed and operational in the Cisco uBR10012 router.

Complete a basic configuration of the Cisco uBR10012 router; this includes, at a minimum, the following tasks:

Configure a host name and password for the router.

Configure the router to support Internet Protocol (IP) operations.

Install and configure at least one WAN adapter to provide backbone connectivity.

Install at least one Cisco OC-48 DPT⁄POS interface module in an appropriate slot of the Cisco uBR10012 chassis. This is described in the online document, Cisco uBR10012 OC-48 DPT/POS Interface Module:

http://www.cisco.com/en/US/docs/cable/cmts/ubr10012/installation/field_replaceable_units/ub_oc48.html

Bring up the router as described in the "Configuring the Cable Modem Termination System for the First Time" chapter in the Cisco uBR10012 Universal Broadband Router Software Configuration Guide:

Determine a channel plan for your Cisco uBR10012 router and all of its cable interfaces.

Verify that your headend site includes all necessary servers to support DOCSIS and Internet connectivity, including Dynamic Host Configuration Protocol (DHCP), Time-of-Day (ToD) and Trivial File Transfer Protocol (TFTP) servers.

Restrictions for Configuring the Cisco uBR10012 OC-48 DPT/POS Interface Module

The following operational considerations apply to the Cisco OC-48 DPT⁄POS interface module:

Command-line interface (CLI) configuration commands are synchronized only with the standby Performance Routing Engine (PRE) module. Any configuration that is done with SNMP commands is not synchronized with the standby PRE module, and is not present after a switchover.

In POS mode, the Cisco OC-48 DPT⁄POS interface module may be installed as a single- or dual- mode interface module. Only one card is required when operating in POS mode.

In SRP mode, the Cisco OC-48 DPT⁄POS interface module cannot be installed as a single interface module. You must configure the OC-48 DPT⁄POS interface modules in pairs using adjacent slots (slots 1/0/0 and 2/0/0 together, or slots 3/0/0 and 4/0/0 together). You can also configure four interface modules as two pairs.

For either POS or SRP mode, slot preconfiguration is required prior to configuring additional settings. Refer to the "Preconfiguring the Slots for the Cisco OC-48 DPT⁄POS Interface Module" section.

How to Configure the Cisco OC-48 DPT⁄POS Interface Module

This section contains the following procedures:

Preconfiguring the Slots for the Cisco OC-48 DPT⁄POS Interface Module

Configuring POS Interfaces on the Cisco OC-48 DPT⁄POS Interface Module

Configuring SRP Interfaces on the Cisco OC-48 DPT⁄POS Interface Module

Configuring SDCC Interfaces on the Cisco OC-48 DPT⁄POS Interface Module

Preconfiguring the Slots for the Cisco OC-48 DPT⁄POS Interface Module

This section includes the following required and optional subsections:

SUMMARY STEPS

DETAILED STEPS

Examples

You must issue the hw-module slot x { pos | srp } and card commands to assign the supported mode to the interface module pairs and to preconfigure the slots to which the interface module pairs are assigned. Perform this preconfiguration prior to any additional POS or SRP mode configurations. Refer to the Cisco IOS CMTS Cable Command Reference Guide for additional command syntax information that applies to additional field-replaceable units (FRUs).


Tip When a card has been preprovisioned and is not physically present in the chassis, the show interface command for the corresponding slot displays the message "Hardware is not present." Some show commands might also list the preprovisioned line card in their displays.


Perform the following steps to preconfigure the Cisco OC-48 DPT⁄POS interface module slots to support POS or SRP.

SUMMARY STEPS

1. enable

2. config t

3. hw-module slot x { pos | srp }

4. card slot/port {1oc48dpt-pos-1}

5. copy running-config startup-config

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

enable

Example:

Router> enable

Enables privileged EXEC mode.

Enter your password if prompted.

Step 2 

configure terminal

Example:

Router# configure terminal

Enters global configuration mode and specifies that the console terminal will be the source of the configuration commands.

Step 3 

hw-module slot slot-number { pos | srp }

no hw-module slot x { pos | srp }

Example:

Router# hw-module slot 3 pos

Assigns the mode of operation to the interfaces. To change the mode of operation for the pairs of interface modules, first issue the no form of this command prior to setting it to the new mode.

Refer to the hw-module slot pos command topic for additional command reference information.

Note The hw-module slot x pos command must be issued for each interface module you want to set into POS mode. Dual-interface modules are not required for POS.

Note The hw-module slot x srp command need be issued only on the odd slot of the pair.

Step 4 

card slot/port {1oc48dpt-pos-1}

Example:

Router# card 3/0 1oc48dpt/pos-1

Preprovisions a slot in the Cisco uBR10012 router for a particular interface module. To remove the preprovisioning for a card, so that the physical slot reports being empty, use the no form of this command.

Note Two adjacent slots must be preprovisioned to support a pair of OC-48 DPT/POS interface modules.

Refer to the card command topic for additional command reference information.

Step 5 

copy running-config startup-config

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.


Note The card 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.



Note The type of card must be appropriate for the slot being specified. Note that 1choc12-1, 1oc12atm-1, and 6cht3-1 line cards are not supported on the Cisco uBR10012 router.

Configuring the Cisco OC-48 DPT⁄POS Interface Modules for POS

The following procedure is for creating a basic configuration, enabling a POS 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 a POS interface address by its line-card slot number and port number, in the format slot/subslot/port. For example, the slot/subslot/port address of an POS 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.

Perform the following steps to initially configure two Cisco OC-48 DPT⁄POS interface modules in slot 3 and slot 4 of a Cisco uBR10012 router.

SUMMARY STEPS

1. enable

2. configure terminal

3. hw-module slot number pos

4. ip routing

5. interface pos slot/subslot/port

6. ip address ip-address mask

7. clock source {internal | line}

8. no cdp enable

9. pos flag { c2 value | j0 value | s1s0 }

10. pos framing { sonet | sdh }

11. pos report option

12. pos scramble-atm

13. pos threshold options

14. Ctrl+Z

15. copy running-config startup-config

16. show interface pos slot/subslot/port

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

enable

Example:

Router> enable

Enables privileged EXEC mode.

Enter your password if prompted.

Step 2 

configure terminal

Example:

Router# configure terminal

Enters global configuration mode and specifies that the console terminal will be the source of the configuration commands.

Step 3 

hw-module slot number pos

Example:

Router(config)# hw-module slot 3 pos

Router(config)# end

Brings up each Cisco OC-48 DPT⁄POS interface module.

Note The hw-module slot x pos command must be issued for each interface module you want to set into POS mode.

Note Dual interface modules are not required for POS.

Refer to the hw-module slot pos command reference topic for additional command syntax information.

Step 4 

ip routing

Example:

Router# ip routing

Enable IP routing by entering the ip routing command in global configuration mode.

Step 5 

interface pos slot/subslot/port

Example:
Router(config)# interface pos 3/0/0
Router(config-if)#

At the prompt, specify the new interface to configure by entering the interface command, followed by the type (pos), and slot/subslot/port (slot number/subslot number/port number).

Step 6 

ip address ip-address mask

Example:
Router(config-if)# ip address 10.0.0.1 
255.255.255.0
Router(config-if)#
 
        

Assigns an IP address and subnet mask to the POS interface.

Step 7 

clock source {internal | line}

Example:
Router(config)# interface pos 1/0/0
Router(config-if)# clock source line

Verify that the default value for the clock source is correct. At the prompt, set the internal or line clock source by using the clock source command.

The default is clock source internal.

Step 8 

no cdp enable

Example:
Router(config-if)# no cdp enable

Turns off the Cisco Discovery Protocol (CDP) in interface configuration mode.

Note Cisco uBR10012 routers do not require CDP.

Step 9 

pos flag { c2 value | j0 value | s1s0 }

Example:

Router(config)# interface pos 5/0/0

Router(config-if)# pos flag c2 0xCF

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 Both Cisco OC-48 DPT⁄POS interface modules in the pair must be configured to support SRP. You must execute the hw-module slot n srp command in privileged EXEC mode to enable the paired modules. Refer to the "Preconfiguring the Slots for the Cisco OC-48 DPT⁄POS Interface Module" section.


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 Side A is automatically the left-most (odd-numbered) slot of the pair of Cisco OC-48 DPT⁄POS interface modules. The SRP interface cannot reside on an even-numbered slot number.


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.

SUMMARY STEPS

1. enable

2. configure terminal

3. hw-module slot slot-number srp

4. end

5. copy running-config startup-config

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

enable

Example:

Router> enable

Enables privileged EXEC mode.

Enter your password if prompted.

Step 2 

configure terminal

Example:

Router# configure terminal

Enters global configuration mode and specifies that the console terminal will be the source of the configuration commands.

Step 3 

hw-module slot slot-number srp

no hw-module slot x srp

Example:

Router(config)# hw-module slot 3 srp

Assigns the mode of operation to the interfaces. To change the mode of operation for the pairs of interface modules, first issue the no form of this command prior to setting it to the new mode (srp).

Note The hw-module slot x srp command need be issued only on the odd slot of the pair.

For additional command syntax information, refer to the
hw-module slot srp command reference section.

Step 4 

end

Example:

Router(config)# end

Router#

Returns you to privileged EXEC mode.

Step 5 

copy running-config startup-config

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 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.

SUMMARY STEPS

1. enable

2. show version

3. show interface srp slot/subslot/port

4. configure terminal

5. ip routing

6. interface srp slot/subslot/port

7. ip address ip-address mask

8. srp clock-source line n

9. no cdp enable

10. srp framing

11. srp topology-timer

12. srp tx-traffic-rate

13. srp priority-map transmit

14. srp priority-map transmit value

15. Additional interface configurations, as required

16. Ctrl-Z

17. copy running-config startup-config

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

enable

Example:

Router> enable

Enables privileged EXEC mode.

Enter your password if prompted.

Step 2 

show version

Example:

Router# show version

Confirms that the system recognizes the cards. For sample output, refer to the show version command reference section.

Step 3 

show interface srp slot/subslot/port

Example:

Router# show interface srp 3/0/0

Router#

Check the status of each port using the show interface srp command in global configuration mode.

For sample output, refer to the show interface srp command reference section.

Step 4 

configure terminal

Example:
Router# configure terminal 
Router(config)# 
 
        

Enters global configuration mode and specifies that the console terminal will be the source of the configuration commands.

Step 5 

ip routing

Example:
Router(config)# ip routing
Router(config)#
 
        

Enables IP routing.

Step 6 

interface srp slot/subslot/port

Example:
Router(config)# interface srp 3/0/0
Router(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 
255.255.255.0
Router(config-if)#
 
        

Assigns an IP address and subnet mask to the SRP interface.

Step 8 

srp clock-source line n

Example:

Router(config-if)# srp clock-source line a

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.

Step 9 

no cdp enable

Example:
Router(config-if)# no cdp enable

Turns off the Cisco Discovery Protocol (CDP) in interface configuration mode.

Note Cisco uBR10012 routers do not require CDP.

Step 10 

srp framing

Example:
Router1(config-if)# srp framing sdh
Router1(config-if)# 
 
        

Selects SRP framing for the interface.

Step 11 

srp topology-timer

Example:
Router1(config-if)# srp topology-timer 60
Router1(config-if)#
 
        

Sets the topology timer frequency in seconds for the specified interface.

Note Cisco recommends that all nodes on the SRP ring have the same wait-to-restore, topology timer and IPS values.

Step 12 

srp tx-traffic-rate

Example:
Router1(config-if)# srp tx-traffic-rate 
high 622
Router1(config-if)# srp tx-traffic-rate 
low 1866

Defines 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 5
Router1(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 5

Maps SRP packets to a specific SRP priority (greater than or equal to the value setting to the high priority queue).

Note The no form of this command sets the default mapping to 6.

Step 15 

Additional interface configurations.

Add any other interface configurations as you require, such as enabling routing protocols or adjusting interface characteristics.

Step 16 

Ctrl-Z

Example:

Ctrl-Z

When 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 17 

copy running-config startup-config

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:

Automatic SRP IPS modes take effect when the DPT ring detects an event, fiber cut, or node failure. The SRP IPS modes remain in effect until the default wait-to-restore (wtr) value expires.

User-configured SRP IPS modes take effect as soon as you enter the commands. The SRP IPS modes remain in effect until you override it with an SRP IPS request with higher priority, or enter the no form of the SRP IPS request to negate the command.


Note Before any physical manipulation to the line card, add an srp ips request forced-switch to the side of the ring that is to be changed.


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.

Table 4 Explanation of SRP IPS Modes

SRP IPS Request
Explanation

Forced-Switch

Adds a high-priority protection switch wrap on each end of a specified span by entering the srp ips request forced-switch command.

Manual-Switch

Adds a low-priority protection switch wrap on each end of a specified span by entering the srp ips request manual-switch command.


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 An exception is that multiple signal fail and forced-switch requests can coexist on the SRP ring.


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.

SUMMARY STEPS

1. enable

2. configure terminal

3. interface srp slot/subslot/port

4. srp ips request manual-switch or no srp ips request forced-switch

5. srp ips wait-to-restore timer seconds

6. srp ips timer seconds

7. end

8. copy running-config startup-config

9. show srp slot/subslot/port

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

enable

Example:

Router> enable

Enables privileged EXEC mode.

Enter your password if prompted.

Step 2 

configure terminal

Example:

Router# configure terminal

Enters global configuration mode.

Step 3 

interface srp slot/subslot/port

Example:
Router(config)# interface srp 1/0/0
Router(config-if)#
 
        

Specifies the new SRP interface to configure. The prompt changes to interface configuration mode.

Step 4 

srp ips request manual-switch

or

no srp ips request forced-switch

Example:

manual-switch a
Router(config-if)#
 
        

or

Router(config-if)# srp ips request 
forced-switch a
Router(config-if)#
 
        

Enters a user-configured manual-switch or forced-switch wrap.

To enter a manual-switch wrap, enter the srp ips request manual-switch interface configuration command and specify side A or side B. The manual switch wrap will disappear when the default wait-to-restore expires.

Note A manual-switch does not appear in the show running configuration command output.

To enter a forced-switch wrap state, enter the srp ips request forced-switch interface configuration command and specify side A or side B.

To disable a forced-switch wrap, enter the no srp ips request forced-switch interface configuration command and specify side A or side B.

Note A forced-switch will override a signal degrade.

Step 5 

srp ips wait-to-restore timer seconds

Example:
Router(config-if)# srp ips wtr-timer 60
 
        

Sets a non-default value of the wait-to-restore request in seconds.

Note All nodes on the SRP ring should have the same wait-to-restore timer, topology timer and IPS values.

Step 6 

srp ips timer seconds

Example:
Router(config-if)# srp ips timer 30
Router(config-if)#
 
        

Sets a non-default value for the frequency of IPS messages to display. Specify the value in seconds.

Step 7 

end

Example:
Router(config-if)# end
Router#
 
        

Type end until you return to the privileged EXEC mode.

Step 8 

copy running-config startup-config

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.

Step 9 

show srp slot/subslot/port

Example:
Router# show srp 1/0/0
Router#
 
        

Use the show srp slot/subslot/port EXEC command to display the status of the SRP IPS requests.

Examples

The following example illustrates configuration for a Cisco uBR10012 router with SRP interfaces in slot 1/subslot 0/port 0.

Router# show running-config interface srp 1/0/0
 
   
ip address 10.0.0.1 255.255.255.0
no shutdown
no cdp enable
no ip mroute-cache
 
   

Configuring SDCC Interfaces on the Cisco OC-48 DPT⁄POS Interface Module

This section describes how to configure and activate SDCC network interfaces to permit remote management and interoperability with the Cisco OC-48 DPT⁄POS interface module.This topic lists the commands that are available when you configure a SONET Section Data Communications Channel (SDCC) interface on the router.


Note The Cisco OC-48 DPT⁄POS interface module allows for SONET Section Data Communications Channel (SDCC) in either POS or SRP modes.


Perform the following steps to enable, configure and verify the SDCC interface.

SUMMARY STEPS

1. enable

2. configure terminal

3. sdcc enable

4. interface sdcc slot/subslot/port then no shutdown

5. loopback

6. crc { 16 | 32 }

7. mtu mtu bytes

8. hold-queue number in

9. Ctrl-Z

10. show interface sdcc slot/subslot/port

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

enable

Example:

Router> enable

Enables privileged EXEC mode.

Enter your password if prompted.

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 If you enter the no sdcc enable command after configuring an SDCC interface, the interface is removed from the interface list in the configuration.

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 8/0/0
Router (config-if)# no shutdown
 
        

To 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 2/0/0
Router(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] loopback

Example:
Router(config-if)# loopback
 
        

Configures 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 16
 
        

Configures 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.

16—Sets the CRC to 16 bits.

32—Sets the CRC to 32 bits. The default setting is 32.

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 The MTU size does not include the 4 bytes for the HDLC header, or the 2 or 4 bytes of the CRC.

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)# ^Z
 
        

When 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

slot

Cisco CMTS chassis slot number for the card. The valid range is 1 to 8.

port

Cisco CMTS port number for the card. The valid values are 0 or 1, depending on the slot number.

1cable-mc16c

Preprovisions a slot for a Cisco uBR-LCP-MC16C or Cisco uBR-LCP2-MC16C cable interface line card.

1cable-mc16e

Preprovisions a slot for a Cisco uBR-LCP-MC16E or Cisco uBR-LCP2-MC16E cable interface line card.

1gigethernet-1

Preprovisions a slot for a Cisco uBR10-1GE Gigabit Ethernet (GE) uplink line card.

12.2(11)BC3

This command introduced in support of the Cisco OC-48 DPT⁄POS interface module on the Cisco uBR10012 router with PRE1 route processors.

12.3(9a)BC

Support added for the Cisco uBR10012 router with PRE2 route processors.


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 When a card has been preprovisioned and is not physically present in the chassis, the show interface command for that slot displays the message "Hardware is not present." Some show commands might also list the preprovisioned card in their displays.


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.

Router# config t 
 
   
Router(config)# card 5/0 ? 
 
   
1cable-mc16c create a uBR10000 line card with MC16C 
1cable-mc16e create a uBR10000 line card with MC16E 
1gigethernet-1 create a GE_1_PORT cardtype 
1oc12pos-1 create a OC12POS_1_PORT cardtype 
2cable-mc28bnc create a uBR10000 line card with MC28C, BNC connector 
2cable-mc28c create a uBR10000 line card with MC28C 
2oc12srp-sm-lr create a uBR10000 oc12 SRP card with SM LR 
Router(config)# card 8/0 2cable-mc28c 
 
   
Router(config)# int c8/0

12.3(9a)BC

Support added for the Cisco uBR10012 router with PRE2 route processors.


Usage Guidelines

You must first use the hw-module slot pos command to preconfigure a line card slot for POS operation of the Cisco uBR10012 OC-48 DPT card before you can configure the card with any further commands. You must also use the card 1oc48dpt-pos-1 command to configure the card slot for the proper card type.


Note If you have previously used the hw-module slot srp command to configure line card slots for Spatial Reuse Protocol (SRP) operation, you must first cancel that configuration using the
no hw-module slot srp
command before you can configure the slots for POS operation using the hw-module slot pos command.


Examples

The following example shows the Cisco uBR10012 OC-48 DPT line card in slot 3 being configured for POS operation:

Router(config)# hw-module slot 3 pos 
 
   
Router(config)# card 3/0 1oc48dpt-pos-1 
 
   

The following example shows the Cisco uBR10012 OC-48 DPT line cards in slots 3 and 4 being reconfigured from SRP operation to POS operation:

Router(config)# no hw-module slot 3 srp 
 
   
Router(config)# no hw-module slot 4 srp 
 
   
Router(config)# hw-module slot 3 pos 
 
   
Router(config)# card 3/0 1oc48dpt-pos-1 
 
   
Router(config)# hw-module slot 4 pos 
 
   
Router(config)# card 4/0 1oc48dpt-pos-1 
 
   

hw-module slot srp

To configure a line card slot for Spatial Reuse Protocol (SRP) operation, use the hw-module slot srp command in global configuration mode. To remove the configuration for a line card slot, use the no form of this command.

hw-module slot slot-number srp

no hw-module slot slot-number srp

Syntax Description

slot slot-number

The physical slot in which the line card is located. Valid range is from 1-8. Start with the left-most interface module, or side A.

srp

Allocates the selected slot to support SRP mode. In SRP mode there is one interface for each pair of interface modules (1/0/0 and 2/0/0 or 3/0/0 and 4/0/0). The interface resides on the odd slot of the pair and is referenced as such.


Defaults

Line card slots are not defined, by default, and must be set to either POS or SRP mode.

12.2(11)BC3

This command introduced in support of the Cisco OC-48 DPT⁄POS interface module on the Cisco uBR10012 router with PRE1 route processors.

12.3(9a)BC

Support added for the Cisco uBR10012 router with PRE2 route processors.

12.2(33)SCB

This command is obsolete.


Usage Guidelines

You must first use the hw-module slot srp command to preconfigure a line card slot for SRP operation of a pair of Cisco uBR10012 OC-48 DPT cards before you can configure the cards with any further commands. You must also use the card 1oc48dpt-pos-1 command to configure each card slot for the proper card type.


Tip The Cisco uBR10012 OC-48 DPT line cards support SRP operation only when installed in adjacement odd- and even-numbered slots (such as slots 1 and 2 or 3 and 4). You need to use the hw-module slot srp command only for the lower-numbered (odd-numbered) slot to preconfigure both slots of the SRP pair.



Note If you have previously used the hw-module slot pos command to configure line card slots for Packet over SONET (POS) operation, you must first cancel that configuration using the no hw-module slot pos command before you can configure the slots for POS operation using the hw-module slot srp command.


Examples

The following example shows the Cisco uBR10012 OC-48 DPT line cards in slots 1 and 2 being configured for POS operation:

Router(config)# hw-module slot 1 srp 
Router(config)# card 1/0/0 1oc48dpt-pos-1 
Router(config)# card 2/0/0 1oc48dpt-pos-1 
 
   

The following example shows the Cisco uBR10012 OC-48 DPT line cards in slots 3 and 4 being reconfigured from POS operation to SRP operation:

 
   
Router(config)# no hw-module slot 3 pos 
Router(config)# no hw-module slot 4 pos 
Router(config)# hw-module slot 3 srp 
Router(config)# card 3/0/0 1oc48dpt-pos-1 
Router(config)# card 4/0/0 1oc48dpt-pos-1 
 
   

loopback

To enable loopback testing on an SDCC interface, in which data is transmitted from the PRE1 or PRE2 module to the OC-48 line card and back, use the loopback command in interface configuration mode. To stop a loopback test, use the no form of this command.

loopback [line | internal]

[no] loopback [line | internal]

Syntax Description

line

This keyword loops the packets received from the line back onto the line at the line card level without being processed in the Route Processor.

internal

This keyword loops the packets received from the route processor back into the line card to the route processor without being sent to the line.


Defaults

Loopback testing is disabled by default.

pos flag

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

c2 value

Path signal identifier, with value being one of the following:

0xCF for PPP or HDLC without scrambling

0x16 for PPP or HDLC with scrambling

j0 value

Section trace byte, with value being 0x01 for interoperability with some Synchronous Digital Hierarchy (SDH) devices in Japan.

s1s0 value

Part of the payload pointer byte, and value is 0 for OC-3c and 2 for AU-4.


Defaults

The default values are as follows:

c2 value is set to 0xCF.

j0 value is set to 0x01.

s1s0 value is set to 0.

Examples

In the following example, the c2 bit is set to 0xCF.

Router(config)# interface pos 4/0/02
Router(config-if)# pos flag c2 0xCF
 
   

pos 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

sdh

Selects SDH framing.

sonet

Selects SONET framing (default).


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:

AU-3—Operates in similar fashion to three sets of H1, H2 and H3 pointers in channelized STS-3 frames.

AU-4—Operates in similar fashion to a single set of pointers in Synchronous Transport Signal-3c (STS-3c) concatenated frames.

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.

Binary Value
Description

00

SONET

11

Reserved

01

Used in older add/drop multiplexers (ADMs).

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 3/0/0
 
   
Router(config-if)# pos report sd-ber
 
   
Router(config-if)# pos report lais
 
   
Router(config-if)# end
 
   
Router#

pos 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.

pos threshold {b1-tca | b2-tca | b3-tca | sd-ber | sf-ber} rate

no pos threshold {b1-tca | b2-tca | b3-tca | sd-ber | sf-ber} rate

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 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 3/0/0
Router(config-if)#  pos threshold sd-ber 8
Router(config-if)#  pos threshold sf-ber 4
Router(config-if)#  pos threshold b1_tca 4
Router(config-if)# end
 
   
Router#
 
   

The following example returns the POS sf-ber threshold back to the default (of 3).

Router(config-if)# pos threshold b1-tca sf-ber 3

Table 7 describes selected fields from the show srp command output.

Table 7 show srp Command Output Fields

Field
Description
IPS Information for Interface 
SRP2/0

IPS (Intelligent Protection Switching) identifies the status of an SRP interface on the SRP ring. The IPS field in the show srp command output is also produced by the show srp ips command output.

MAC Addresses Side A (Outer ring 
RX) neighbor 0012.3456.0002

MAC address of the next SRP node on the outer ring.

MAC Addresses Side B (Inner ring 
RX) neighbor 0012.3456.0002

MAC address of the next SRP node on the inner ring.

Node MAC address 0012.3456.0001

MAC address of this SRP node.

IPS State

Reports whether or not a wrap exists on side A or side B of the SRP ring.

IPS WTR period is 60 seconds 
(timer is inactive)

Current Wait-to-Restore (WTR) timer value. If a timer is active, the time remaining before the timer expires will also be given.

Node IPS State IDLE

Displays the current IPS state of the node. IDLE is the normal state. Other states are WRAPPED and PASSTHRU.

IPS self-detected requests

Indicates any locally generated requests.

Indicates any remotely generated requests.

Displays local IPS requests, as well as IDLE status.

Possible requests include the following:

FS — Forced Switch

SF — Signal Fail

SD — Signal Degrade

MS — Manual Switch

WTR — Wait to Restore

IPS remote requests 

Indicates any locally generated requests.

Indicates any remotely generated requests.

Displays remote IPS requests, as well as IDLE status.

Possible requests include the following:

FS — Forced Switch

SF — Signal Fail

SD — Signal Degrade

MS — Manual Switch

WTR — Wait to Restore

IPS messages received

Indicates IPS messages received on side A {0012.3456.0002,IDLE,S}, TTL 128.

Indicates IPS messages received on side B {0012.3456.0004,IDLE,S}, TTL 128.

Provides details of the last IPS messages received. Fields within the braces ({}) are the MAC addresses of the sending node and the APS state (IDLE, LO, FS, and so on). It also indicates either a short (S) or long (L) path.

IPS messages transmitted

Indicates IPS messages received on side A {0012.3456.0001,IDLE,S}, TTL 128.

Indicates IPS messages received on side B {0012.3456.0001,IDLE,S}, TTL 128.

Provides details of the last IPS messages transmitted, in the format used for received messages.

Source address information for 
interface SRP2/0

SRP source-counter information that identifies the SRP interface. This section of the show srp command output is also produced by show srp source-counters command output.

0012.3456.0001, index 1, packet 
count 409847

Initial number of the MAC address of the SRP node whose packets are being counted. The index refers to an internal detail of the SRP implementation and has no operational significance. Packet count indicates that packets from the MAC address are being counted, and the actual count will follow.

Topology map for interface 
SRP2/0

SRP topology information that identifies the SRP interface. This section of the show srp command output is also produced by show srp topology command output.

Topology packet sent every 10 
seconds (next packet after 5 
seconds)

Interval between successive topology packets sent from this node and the time until the next one is to be sent (rounded down to the nearest second).

Last received topology packet 
00:00:04

Time since the last topology packet was received at this node.

Nodes on the ring: 4

Number of nodes in the current ring topology.

Hops

Number of hops to the destination node, beginning with the assumption that the node is traveling on side A. The local node is at hop count zero.

MAC

MAC address of the node.

IP Address

IP address of the SRP interface on the node. If the address is not known, the text string "unknown" will be displayed.

Note that the IP address information is gathered by the ARP table. When a ring is first established, it is normal for the IP address of a node to remain unknown until some time after the MAC address is known. If the topology continues to display unknown for the IP address after a reasonable length of time, there is probably a problem with address resolution protocol.

Wrapped

Indicates whether the SRP ring is wrapped at that node, by either Yes or No.

Name

Host name of the router. If the name is not known, this field is left blank.

Note that the host name is obtained from information that is broadcast on the ring at a slower rate than other topology information. When a ring is first established, it is normal for the host name of a remote node to remain unknown until some time after the MAC address is known.

srp clock-source

To configure the clock source, use the srp clock-source command in interface configuration mode. To restore the default srp clock-source, use the no form of this command .

srp clock-source [line | internal] [a | b]

no srp clock-source [line | internal] [a | b]

Syntax Description

line

Clock source as line. Used when connecting a router to SONET/SDH ADM.

internal

Clock source as internal. Used when connecting between two routers over dark fiber or over a Wavelength Division Multiplexing (WDM) system.

a

Clock source on side A of the router.

b

Clock source on side B of the router.


Defaults

The default setting is both interfaces set to internal. This is recommended for optimal clocking.

12.2(11)BC3

This command introduced in support of the Cisco OC-48 DPT⁄POS interface module on the Cisco uBR10012 router with PRE1 route processors.

12.3(9a)BC

Support added for the Cisco uBR10012 router with PRE2 route processors.


Usage Guidelines

This command applies to Spatial Reuse Protocol (SRP) interfaces only.

When you configure a connection between two Cisco 10700 Series Internet Routers, you can configure the SRP interfaces for clock source as follows:

You can set both interfaces to internal. This is the default setting and is recommended for optimal clocking.

Setting both SRP interfaces to line is not supported.

You can configure the SRP interface on one side of the connection as internal and the SRP interface on the other side as line. This is available for installations in which line timing is desirable, such as add/drop multiplexer (ADM) and wavelength division multiplexing (WDM).

Examples

The following is an example of how to use the srp clock-source command to select line as a clock source on side A:

Router# configure terminal
Router(config)# interface srp 1/0/0
Router(config-if)# srp clock-source line a
Router(config-if)#
 
   

srp flag

To specify SONET/Synchronous Digital Hierarchy (SDH) overhead values for the frame header, use the srp flag command in interface configuration mode. Use the no form of this command to restore the default SRP flag.

srp flag [c2 | j0] value [a | b]

no srp flag [c2 | j0] value [a | b]

Syntax Description

c2 value

Path signal label byte.

j0 value

Section trace byte. For interoperability with some SDH equipment in Japan, use the value 0x1.

a

Side of a node that has outer ring receive fiber is identified as side A.

b

Side of a node that has inner ring receive fiber is identified as side B.


Defaults

The default c2 value is 0x16, and the default j0 value is 0xCC.

12.3(9a)BC

Support added for the Cisco uBR10012 router with PRE2 route processors.


Usage Guidelines

This command applies to SRP interfaces only. If a node (side A or side B) is not specified in the command, the IPS timer value is applied to both sides.

Examples

The following example shows how to use the srp ips timer command to set the frequency of IPS request transmission to 5 seconds on side A:

Router# configure terminal
Router(config)# interface srp 1/0/0
Router(config-if)# srp ips timer 5 a
Router(config-if)#

12.2(11)BC3

This command introduced in support of the Cisco OC-48 DPT⁄POS interface module on the Cisco uBR10012 router with PRE1 route processors.

12.3(9a)BC

Support added for the Cisco uBR10012 router with PRE2 route processors.


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 terminal
Router(config)# interface srp 1/0/0
Router(config-if)# srp ips wtr-timer 10
Router(config-if)# end
 
   

srp 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

internal

Internal (framer) loopback.

line

Loopback line data.

a

The side of a node that has outer ring receive fiber is identified as side A.

b

The side of a node that has inner ring receive fiber is identified as side B.

12.3(9a)BC

Support added for the Cisco uBR10012 router with PRE2 route processors.


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 terminal
Router(config)# interface srp 1/0/0
Router(config-if)# srp loopback line a
Router(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.

12.3(9a)BC

Support added for the Cisco uBR10012 router with PRE2 route processors.


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 5
 
   
 
   

srp 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.

12.3(9a)BC

Support added for the Cisco uBR10012 router with PRE2 route processors.


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 The srp shutdown command differs from the shutdown command in the following manner:
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 terminal
Router(config)# interface srp 1/0/0
Router(config-if)# srp shutdown a
Router(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.

12.3(9a)BC

Support added for the Cisco uBR10012 router with PRE2 route processors.


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 terminal
Router(config)# interface srp 1/0/0
Router(config-if)# srp topology-timer 100
Router(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.

12.3(9a)BC

Support added for the Cisco uBR10012 router with PRE2 route processors.


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 High-priority traffic in transit on the ring is not controlled by the SRP fairness algorithm. Cisco recommends that the TX-traffic-rate for high-priority traffic not be disabled in order to prevent high-priority traffic transmitted from one node on the ring from starving traffic transmitted by other nodes on the SRP ring.


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 terminal
Router(config)# interface srp 1/0/0
Router(config-if)# srp rate-limit hi 622
Router(config-if)# srp rate-limit low 1866
Router(config-if)# end
