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 12.1 commands, refer to the Cisco IOS documentation set available from the Cisco.com home page. Use the Select an Area pull-down menu to select Products and Services > Technical Documentation. On the Cisco Product Documentation home page, select Release 12.1 from the Cisco IOS Software drop-down list.
[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
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 card. When enabled, both summertime and timezone are automatically configured, and the system clock is periodically synchronized to the TCC2 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
interface spr 1
Use this command to create a shared packet ring (spr) interface on an ML-Series card for a resilient packet ring (RPR). If the interface has already been created, this command enters spr interface configuration mode. The only valid spr interface number is 1.
Defaults
N/A
Command Modes
Global configuration
Usage Guidelines
The command allows the user to create a virtual interface for the RPR/SPR. Commands such as spr wrap or spr station-id can then be applied to the RPR through SPR configuration command mode.
Examples
The following example creates the shared packet ring interface:
Router(config)# interface spr 1
Related Commands
spr drpri-id
spr-intf-id
spr station-id
spr wrap
[no] pos flag c2 value
Use this command to specify the C2 byte value for transmitted and received frames. Use the no form of the command to return the C2 byte to it's default value.
Syntax Description
|
|
|
|---|---|
value |
C2 byte value |
Defaults
When changing the encapsulation on a Packet over SONET/SDH (POS) port between LEX and Point-to-Point Protocol/high-level data link control (PPP/HDLC), the scrambling and c2 settings are automatically changed to their default values according to Table A-1.
|
|
|
|
|---|---|---|
LEX |
pos scramble-spe |
pos flag c2 0x01 |
PPP/HDLC |
no pos scramble-spe |
pos flag c2 0xCF |
In PPP/HDLC encapsulation, changing the scrambling, automatically changes the "pos flag c2" to its default according to Table A-2. In LEX encapsulation, changing the scrambling does not affect c2.
|
|
|
|
|---|---|---|
PPP/HDLC |
pos scramble-spe |
pos flag c2 0xCF |
PPP/HDLC |
no pos scramble-spe |
pos flag c2 0x16 |
Command Modes
Interface configuration mode (packet over SONET [POS] only)
Usage Guidelines
This value is normally configured to match the setting on the peer path terminating equipment (PTE). Using the correct order of operations will avoid having the nondefault settings overridden by the encapsulation change. The recommended order follows:
1. Set encap to PPP/HDLC
2. Set scrambling (if a nondefault setting is required)
3. Set c2 (if a nondefault setting is required)
Also note that the cyclic redundandy check (CRC) setting varies among different types of PTE. The default CRC on the ML-Series card is 32-bits, regardless of any other settings. In most circumstances, the default settings should be correct, but users need to verify this with the user documentation for the PTE.
Examples
Gateway(config)# int pos0
Gateway(config-if)# pos flag c2 0x16
Related Commands

[no] pos pdi holdoff time
Use this command to specify the time, in milliseconds, to holdoff sending the path defect indication (PDI) to the far-end when a VCAT member circuit is added to the virtual concatenation group (VCG). Use the no form of the command to use the default value.
Syntax Description
|
|
|
|---|---|
time |
delay time in milliseconds, 100 to 1000 |
Defaults
The default value is 100 milliseconds.
Command Modes
Interface configuration mode (POS only)
Usage Guidelines
This value is normally configured to match the setting on the peer PTE. The time granularity for this command is 1 milliseconds.
Examples
Gateway(config)# int pos0
Gateway(config-if)# pos pdi holdoff 500
Related Commands

[no] pos report alarm
Use this command to specify which alarms/signals are logged to the console. This command has no effect on whether alarms are reported to the TCC2/TCC2P and CTC. These conditions are soaked and cleared per Telcordia GR-253. Use the no form of the command to disable reporting of a specific alarm/signal.
Syntax Description
Defaults
The default is to report all alarms.
Command Modes
Interface configuration mode (POS only)
Usage Guidelines
This value is normally configured to match the setting on the peer PTE.
Examples
Gateway(config)# int pos0
Gateway(config-if)# pos report all
Gateway(config-if)# pos flag c2 1
03:16:51: %SONET-4-ALARM: POS0: PPLM
Gateway(config-if)# pos flag c2 0x16
03:17:34: %SONET-4-ALARM: POS0: PPLM cleared
Related Commands

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

Assigns the POS interface to the SPR interface.
Syntax 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
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
|
|
|
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
|
|
|
|---|---|
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
