Command Reference



Note The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.


This appendix provides a command reference for those Cisco IOS commands or those aspects of Cisco IOS commands unique to ML-Series cards. For information about the standard Cisco IOS Release 12.2 commands, refer to the Cisco IOS documentation set available at http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/.

[no] bridge bridge-group-number protocol {drpri-rstp | ieee | rstp}

To define the protocol employed by a bridge-group, use the bridge protocol global configuration command. If no protocol will be employed by the bridge-group, this command is not needed. To remove a protocol from the bridge group, use the no form of this command with the appropriate keywords and arguments.

Syntax Description

Parameter
Description

drpri-rstp

The protocol that enables the Dual RPR Interconnect (DRPRI) feature of the ML-Series cards.

ieee

IEEE 802.1D Spanning Tree Protocol.

rstp

IEEE 802.1W Rapid Spanning Tree Protocol.

bridge-group-number

The identifying number of the bridge group being assigned a protocol.


Defaults

N/A

Command Modes

Global configuration

Usage Guidelines

The protocol DRPRI-RSTP is only employed when configuring ML-Series cards as part of a DRPRI. A bridge group with DRPRI is limited to one protocol, so the bridge group cannot also implement rapid spanning tree protocol (RSTP) or spanning tree protocol (STP).

Examples

The following example assigns the DRPRI protocol to the bridge group with the bridge group number of 100.

Router(config)# bridge 100 protocol drpri-rstp

[no] clock auto

Use the clock auto command to determine whether the system clock parameters are configured automatically from the TCC2/TCC2P card. When enabled, both summertime and timezone are automatically configured, and the system clock is periodically synchronized to the TCC2/TCC2P card. Use the no form of the command to disable this feature.

Syntax Description

This command has no arguments or keywords.

Defaults

The default setting is clock auto.

Command Modes

Global configuration

Usage Guidelines

The no form of the command is required before any manual configuration of summertime, timezone, or clock. The no form of the command is required if Network Time Protocol (NTP) is configured in Cisco IOS. The ONS 15454 SONET/SDH is also configured through Cisco Transport Controller (CTC) to use a NTP or Simple Network Time Protocol (SNTP) server to set the date and time of the node.

Examples

Router(config)# no clock auto

Related Commands

clock summertime

clock timezone

clock set

[no] pos vcat resequence {enable | disable}

Enables or disables the SW-LCAS H4 byte sequence number re-sequence feature. If an ML-Series card running Software Release 4.6.2 or later is interoperating with an ML-Series card running Software Release 4.6.0 or 4.6.1, then the pos vcat resequence disable command must be added to the configuration of the ML-Series card running R4.6.2 or later.

Syntax Description

Parameter
Description

Enable

Enables the re-sequencing of the H4 byte sequence numbers when a member is added to the VCAT group or removed from the VCAT group. If both members are up, then member #0 will have sequence number of zero (0) and member #1 will have sequence number one (1). If only one member is up, then the sequence number of that member will be zero (0).

Disables

spr drpri-id { 0 | 1 }

Creates a DRPRI identification number of 0 or 1 to differentiate between the ML-Series cards paired for the DRPRI protection feature.

Defaults

N/A

Command Modes

Shared packet ring (SPR) interface configuration

Usage Guidelines

DRPRI paired sets share the same SPR station ID, so the DRPRI identification number helps identify a particular card in a DRPRI pair.

Examples

The following example assigns a DRPRI identification number of zero to the SPR interface on an ML-Series card:

Router(config)# interface spr 1
Router(config-if)# spr drpri-id 0

Related Commands

interface spr 1

spr-intf-id

spr station-id

spr wrap

spr-intf-id shared-packet -ring-number

Assigns the POS interface to the SPR interface.

Syntax Description

Parameter
Description

shared-packet-ring-number

The only valid shared-packet-ring-number (SPR number) is 1.


Defaults

N/A

Command Modes

POS interface configuration

Usage Guidelines

The SPR number must be 1, which is the same SPR number assigned to the SPR interface.

The members of the SPR interface must be POS interfaces.

An SPR interface is configured similarly to a EtherChannel (port-channel) interface. Instead of using the channel-group command to define the members, you use the spr-intf-ID command. Llike port-channel, you then configure the SPR interfaces instead of the POS interface.

Examples

The following example assigns an ML-Series card POS interface to an SPR interface with a shared-packet-ring-number of 1:

Router(config)# interface pos 0
Router(config-if)# spr-intf-id 1

Related Commands

interface spr 1

spr drpri-id

spr station-id

spr wrap

[no] spr load-balance { auto | port-based }

Specifies the RPR load-balancing scheme for Unicast packets.

Syntax Description

Parameter
Description

auto

The default auto option balances the load based on the MAC addresses or source and destination addresses of the IP packet.

port-based

The port-based load balancing option maps even ports to the POS 0 interface and odd ports to the POS 1 interface.


Defaults

The default setting is auto.

Command Modes

SPR interface configuration

Examples

The following example configures an SPR interface to use port-based load balancing:

Router(config)# interface spr 1
Router(config-if)# spr load-balance port-based

Related Commands

interface spr 1

spr station-id station-id-number

Configures a station ID.

Syntax Description

Parameter
Description

staion-id-number

The user must configure a different number for each SPR interface that attaches to the RPR. Valid station ID numbers range from 1 to 254.


Defaults

N/A

Command Modes

SPR interface configuration

Usage Guidelines

The different ML-Series cards attached to the RPR all have the same interface type and number, spr1. The station ID helps to differentiate the SPR interfaces.

Examples

The following example sets an ML-Series card SPR station ID to 100:

Router(config)# interface spr 1
Router(config-if)# spr station-id 100

Related Commands

interface spr 1

spr drpri-id

spr-intf-id

spr wrap

spr wrap immediate | delayed

Sets the RPR wrap mode to either wrap traffic the instant it detects a link state change or to wrap traffic after the carrier delay, which gives the SONET protection time to register the defect and declare the link down.

Syntax Description

Parameter
Description

immediate

Wraps RPR traffic the instant it detects a link state change.

delayed

Wraps RPR traffic after the carrier delay time expires.


Defaults

The default setting is immediate.

Command Modes

SPR interface configuration

Usage Guidelines

Immediate should be used if RPR is running over unprotected SONET circuits. Delayed should be run for SONET protected circuits (BLSR or path protection).

Examples

The following example sets an ML-Series card to delayed:

Router(config)# interface spr 1
Router(config-if)# spr wrap delayed
