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 that are 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
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-rstpRelated Commands
bridge-group
[no] clock auto
Use the clock auto command to determine whether the system clock parameters are configured automatically from the Advanced Timing, Communications, a nd Control/Advanced Timing, Communications, and Control Plus (TCC2/TCC2P) card. When enabled, both daylight savings time 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 autoRelated Commands
clock

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 1Related Commands
spr drpri-id
spr-intf-id
spr station-id
spr wrap
[no] ip radius nas-ip-address {hostname | ip-address}
The ML-Series card allows the user to configure a separate nas-ip-address for each ML-Series card. This allows the Remote Authentication Dial In User Services (RADIUS) server to distinguish among individual ML-Series card in the same ONS node. If there is only one ML-Series card in the ONS node, this command does not provide any advantage. The public IP address of the ONS node serves as the nas-ip-address in the RADIUS packet sent to the server.
Identifying the specific ML-Series card that sent the request to the server can be useful in debugging from the server. The nas-ip-address is primarily used for validation of the RADIUS authorization and accounting requests.
If this value is not configured, the nas-ip-address is filled in by the normal Cisco IOS mechanism using the value configured by the ip radius-source command. If no value is specified, then the best IP address that routes to the server is used. If no address routing to the server is available, the IP address of the server is used.
Defaults
N/A
Command Modes
Global configuration
Usage Guidelines
This command allows the user to specify the IP address or hostname of attribute 4 (nas-ip-address) in the radius packet.
Examples
The following example creates an IP address for attribute 4 of the RADIUS packet:
Router# configure terminal
Router (config)# [no] ip radius nas-ip-address 10.92.92.92
Related Commands
aaa new-model
aaa authentication login
microcode fail system reload
In the event of a microcode failure, it configures the ML-Series card to save information to the flash memory and then reboot. The information is saved for use by the Cisco Technical Assistance Center (Cisco TAC). To contact TAC, see the Obtaining Technical Assistance, page xxxiv.

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/SDH circuits. Delayed should be run for SONET protected circuits, such as BLSR or path protection, or SDH protected circuits, such as SNCP or MS-SPRing.

Use the no form of this command on both edge devices to delete the VC.
xconnect destination vc-id encapsulation mpls
no xconnect
Note
Syntax Description
Note
Defaults
There are no point-to-point connections configured.
Command Modes
Interface configuration
Usage Guidelines
An MPLS VC runs across an MPLS cloud to connect Ethernet interfaces on two PE-CLE devices at each edge of the service provider network. You must enter the command at the PE device at each edge of the service provider network to establish a bidirectional virtual connection, which consists of two unidirectional label-switched paths (LSPs). A VC is not established if it is not properly defined from both ends.
For the destination parameter, specify the LDP IP address of the other PE-CLE device; do not specify the IP address of the device on which you are entering the command.
The vc-id must be unique for each pair of provider edge devices. Therefore, in large networks, you should keep track of the VC ID assignments to ensure that a VC ID is not assigned more than once.
Examples
This example shows how to establish an EoMPLS tunnel between the PE1 VLAN 3 interfaces and the PE2 VLAN 4 interface. PE1 has IP address 10.0.0.1/32 that PE2 discovers through routing and PE2 has IP address 20.0.0.1/32 that PE1 discovers through routing.
At the PE1 interface:
Switch(config)# interface vlan 3Switch(config-if)# xconnect 20.0.0.1 123 encapsulation mplsAt the PE2 interface:
Switch(config)# interface vlan 4Switch(config-if)# xconnect 10.0.0.1 123 encapsulation mplsRelated Commands
