This document describes Pseudo-IOS command line interface (PCLI) for GE_XP, 10GE_XP, GE_XPE, and 10GE_XPE cards.
Note Unless otherwise specified, “ONS 15454” refers to both ANSI and ETSI shelf assemblies.
Understanding PCLI
PCLI provides an IOS-like command line interface for GE_XP, 10GE_XP, GE_XPE, and 10GE_XPE cards in Layer 2 (L2) mode. PCLI employs the Cisco IOS Modular QoS CLI (MQC).
PCLI is a text interface from where you can operate, provision and retrieve GE_XP, 10GE_XP, GE_XPE, and 10GE_XPE card information. PCLI runs on the Timing, Communications, and Control (TCC) of the node controller, to access card level information. PCLI acts as a Corba client and provides the same provisioning mechanisms as CTC or TL1. PCLI can be accessed via CTC by selecting Tools > Open Pseudo IOS Connection menu option or right-click on the node in the Network View and select Open Pseudo IOS Connection. To access the PCLI text interface use Telnet, or SSH to open a shell session to connect to a GE_XP, 10GE_XP, GE_XPE, or 10GE_XPE card and input IOS-like commands.
To access PCLI from Windows XP, enter the following command at the Windows command prompt:
telnet <node name> <port number>
To access PCLI from Solaris 8, enter the following command:
ssh –p <Port Number> <Node Name>
telnet <Node Name> <Port Number>
The PCLI shell supports the 454 multi-shelf architecture. Multi-shelf supports 16 shelves with each shelf containing 17 slots. The GE_XP, 10GE_XP, GE_XPE, or 10GE_XPE cards can be inserted in any Input/Output (IO) slot or shelf. PCLI also provides a command to virtually connect to a specified shelf/slot. However, connection to a non-Xponder slot or to an Xponder slot that is not in L2 mode is not supported. PCLI supports a maximum of 16 concurrent login sessions per node controller. A session can be cancelled by logging out of the PCLI session or when the idle timer times out.
Note PCLI adheres to the idle user timeout period security policy set via CTC or TL1.
Note For information on viewing security policies, refer the task, “DLP-G189 Change Security Policy for Multiple Nodes” in the Cisco ONS 15454 DWDM Configuration Guide.
If a PCLI session on a node using a given port number is open, the port number used by the PCLI session cannot be changed. When connecting in a Non-Secure state to a node and a port, use the configured port number for non-secured mode only, and when connecting via a Secure state to a node and a port, use the configured port number for Secure mode.
PCLI Security
PCLI supports configurable secure or unsecure access with a configurable port number per access mechanism. Use CTC to view or modify these settings. The default access state is “Non-secure” and the default port number is “65000”.
PCLI supports an unsecured connection via Telnet and a secure connection via Secure Shell (SSH) by using existing system authentication, authorization and accounting (AAA) mechanisms. Login with user/password that is configured at the Network Element (NE). Use CTC or TL1 to manage user accounts.
Note If you have logged in to a PCLI connection in an Non-Secure state and change the connection via CTC to a Secure one (or vice versa), the Non-Secure state in PCLI (or Secure, as the case may be) is closed once the CTC configuration is completed.
For information on setting the access states (Non-secure or Secure), refer Cisco ONS 15454 DWDM Configuration Guide.
PCLI Command Modes
The PCLI supports eight different command modes. Each command mode can be accessed by specifying a command. The prompt changes to reflect the new command mode that you are in. Consequently, the set of valid commands changes to reflect the sub-commands that are allowed within that mode.
The following section shows supported PCLI commands for each command mode.
Common Commands
The following commands are common across all command modes.
?—Enter a question mark (?) at the system prompt to display a list of commands available in each command mode.
!— Enter an exclamation symbol (!) at the system prompt to add comments.
exit—Enter exit at the system prompt to exit from the mode you are currently in.
User EXEC Mode
Prompt: (>)
After a successful login, the system goes to User Executive (EXEC) command mode. Most PCLI commands in the User EXEC mode do not change system operation. The User EXEC mode allows you to work on multiple GE_XP, 10GE_XP, GE_XPE, and 10GE_XPE cards during a single session while restricting the view at any given time to a single card in a specific shelf and slot. This mode displays system wide parameters that span all cards in the node.
The following commands are supported in the User EXEC mode:
In general, the Privileged EXEC commands allow you to connect to remote devices, perform basic tests, and lists system information. Most CLI commands in Privileged EXEC mode do not change or modify provisioning and system operation. The most common EXEC commands are show commands and are used to display configuration or operational data, and do not have capability to modify provisioning.
Enter global configuration mode from privileged EXEC mode. Global configuration commands generally apply to the whole system rather than just one protocol or interface. You can enter other configuration sub modes listed in this section from global configuration mode.
Enter interface configuration mode from global configuration mode. In this mode and other interface sub modes, a wide variety of capabilities are supported. You can configure provisioning on a specific module interface, i.e. port.
Service instance configuration mode is a sub mode of the interface configuration mode and can be used to define service instances, i.e. Ethernet Flow Points (EFPs). EFPs are specific to a particular interface. Multiple EFPs can be strung together to make an Ethernet Virtual Circuit (EVC).
The encapsulation commands can be used in any combination to implement flexible EFPs. However, the dot1q and untagged commands must be used for selective mode translations, and the default command must be used for transparent mode translations. The following restrictions apply to encapsulation commands:
Selective and transparent mode apply to a whole port and are mutually exclusive.
Encapsulation default is for transparent translations. Only one transparent service instance is allowed per port.
Encapsulation untagged is for selective translation with no cvlan tag. If the operation is DOUBLE_ADD ( rewrite ingress tag push dot1q <multipurpose vlan> second-dot1q <svlan>), only one service instance is allowed per port.
Note The encapsulation and rewrite commands are work together. These commands take effect only if the following sequence is followed:
1. Enter the encapsulation command.
2. Enter the rewrite command.
Note A service instance cannot be edited once user exits the service instance configuration mode. To make changes to any of these parameters, delete the service instance and recreate it.
Policy Map Configuration Mode
Prompt: (config-pmap)
Enter policy map configuration mode from global configuration mode by using the policy-map command to create a policy map or modify an existing policy map. This mode is part of the quality-of-service (QoS) feature.
To attach a QoS policy to a specific interface, you must enter interface configuration mode from global configuration mode by identifying the interface and then using the service-policy command to attach an existing policy. QoS policy map provisioning can be accessed across multiple GE_XP, 10GE_XP, GE_XPE, and 10GE_XPE cards.
To enter policy map configuration mode, enter the policy-map name command from the global config mode.
The following commands are part of policy map configuration mode:
VLAN profile configuration mode can be used to provision the parameters for a VLAN profile. A VLAN profile can later be applied to multiple VLANs. VLAN profile provisioning can be accessed across multiple GE cards.
To enter VLAN profile configuration mode, use the vlan profile name command from the global config mode.
The following commands are part of VLAN profile configuration mode:
To enter privileged EXEC mode, use the enable command in user EXEC mode.
enable shelf/slot
Syntax Description
shelf/slot
Shelf and slot number.
Command Modes
User EXEC
Usage Guidelines
Use this command to enter privileged configuration mode. Entering privileged EXEC mode enables the use of privileged commands. Note the prompt for user EXEC mode is the greater than symbol (>), and the prompt for privileged EXEC mode is the hash symbol (#).

set cos number
To set the Layer 2 class of service (CoS) value of an outgoing packet, use the set cos command in policy-map class configuration mode.
set cos number
Syntax Description
number
Specify the CoS value to be applied to the 802.1Q SVLAN tag. Values 0 through 7 specify constant values for the CoS. Values 8 and 9 mean:
8 = TRUST. This value indicates that the CVLAN CoS value must be trusted, i.e. copied into the SVLAN CoS field.
9 = CVLAN. This value indicates that the SVLAN CoS field is set based on the value of the CVLAN ID. This mapping is provided by an EVC service instance. A service instance on an interface can be defined to match frames with one or more CVLANs. That service instance can also have a policy applied that specifies a CoS. The result is a mapping from CVLAN to CoS on an interface.
Defaults
By default, no CoS value is set for the outgoing packet.
Command Modes
Policy-map configuration.
Usage Guidelines
Enter upto 9 CoS values.
Examples
In the following example, the policy map called "cos-set" is created to assign different CoS values for different types of traffic.
MSTP(config)# policy-map cos-set
MSTP(config-pmap-c)# set cos 1
wrr-queue cos-map queue-idcos1 … cosn
To map CoS values to drop thresholds for a queue, use the wrr-queue cos-map command.
