Note
Preparing for Provisioning
Before you begin configuring lines and ports on MPSM-T3E3-155 and MPSM-16-T1E1 service modules, you need to initialize the cards you plan to provision. Then you should develop and implement a plan for the card and line redundancy options available for each service module. This plan determines how service modules and their back cards must be installed in the chassis, and how lines must connect to the cards before software configuration starts. Without a plan developed for these services, a configuration change for any of these services has the potential to interrupt service and can require substantial configuration teardown.
The MPSM-T3E3-155 card supports 1:1 card redundancy, and the MPSM-16-T1E1 card supports both 1:1 and 1:N card redundancy. The MPSM-T3E3-155 card supports both intercard and intracard APS.
The MPSM-T3E3-155 and MPSM-16-T1E1 service modules also require the management of feature licenses. The required feature licenses are described in "MPSM Feature Licenses".
For instructions on initializing cards, configuring card and line redundancy, and managing MPSM feature licenses on the PXM processor card, refer to the:

MPSM Feature Licenses
The MPSM-T3E3-155 and MPSM-16-T1E1 cards require feature licenses to enable the optional MPSM features listed in Table 2-1.
You must have the required license installed in the PXM license pool if you want to use any of the features described. To install and manage licenses on the PXM card, refer to the Cisco MGX 8800/8900 Series Configuration Guide, Release 5.1
For instructions on displaying, moving, and allocating feature licenses, and managing feature license alarms on the MPSM-T3E3-155 and MPSM-16-T1E1 cards, see "Managing Feature Licenses" in Chapter 6, "MPSM-T3E3-155 and MPSM-16-T1E1 Card Management."

General MPSM Provisioning Procedures

Selecting and Viewing Service Class Templates
These topics and procedures describe selecting and viewing Service Class Templates on the MPSM-T3E3-155 and MPSM-16-T1E1 cards:
•
Overview of Service Class Templates
A Service Class Template (SCT) is a file that contains default configuration data for switch connections and for configuring the hardware to support connections. When you configure a connection, or when an SVC is established, the switch analyzes the connection setup request data, any local configuration data, and the SCTs that apply to the port and to the card. For example, if an SPVC configuration does not include required data for the requested class of service (COS), default values from the SCT files are used. If an SVC request or SPVC configuration specifies configuration values that are different from the SCT values, the specified values override the default SCT values.
There are two types of SCTs: card SCTs and port SCTs. Card SCTs define configuration parameters for the hardware that transfers data between the a service module and the switch back plane. You can assign one card SCT to each service module.
Port SCTs define configuration parameters for the hardware that transfers data between a service module and a communication line to another switch or CPE. Port SCTs are assigned when a port is configured, and you can use different port SCTs on the same card, provided that the port SCT you select is designed for that card type.
Some SCT parameters control the service module hardware, and others are used as default values for connection parameters. A complete discussion of the SCT parameters is beyond the scope of this book.
SCT parameters are used to do the following:
•
•
•
•
•
SCTs simplify configuration by providing default values that will work for most connections. This reduces the number of parameters that need to be defined when setting up connections. Without SCTs, you need to perform a lot of detailed manual configuration on each and every port on the switch. This is time consuming and error prone. Typically, traffic profiles are defined by a handful of traffic engineering experts who understand the service level agreements and expected traffic pattern on the ports. These experts define the SCTs for each port in the system. Once the SCT is applied on the port, you do not need to (re)configure the switch. The parameters in the SCTs define generic thresholds and priorities of queues that can be understood without having to go through the programming details of Queuing engines, such as QE1210.
When configuring a service module card SCT, your goal should be to select the card SCT that will support the majority of planned connections on that card. When configuring a service module port SCT, your goal should be to select the port SCT that supports the majority of planned connections on that port.
Each service module contains default SCT parameters that you can use for communications. Cisco also supplies additional SCTs that you can use to better support communications. If none of the Cisco supplied SCTs meet your needs, you can use Cisco WAN Manager (CWM) to create your own custom SCTs. You can not create or modify SCT files using the CLI. For more information on configuring SCTs and SCT parameters, refer to the Cisco WAN Manager User's Guide, Release 15.1.
For information on downloading, registering, and managing SCTs on the PXM card, refer to the Cisco MGX 8800/8900 Series Configuration Guide, Release 5.1
MPSM Service Class Templates
SCT files are applicable to the MPSM-T3E3-155 and MPSM-16-T1E1 cards. Each SCT is classified by card or service module type, by whether it is a card or port SCT, and as either policing or non-policing. Although card SCTs may contain policing parameters, these parameters are ignored. Typically, policing SCTs are used on UNI ports at the edge of the ATM network and control traffic entering the network. Non-policing SCTs are typically on trunk ports that interconnect switches within the network.
Note
Table 2-2 lists the SCTs supplied by Cisco for the MPSM-T3E3-155 and MPSM-16-T1E1 cards. For the very latest information on Cisco SCTs, refer to the Release Notes for Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, and Cisco MGX 8830 Switches, Release 5.1.00

Note
Selecting a Card SCT
A card SCT defines the queue parameters for the destination slot based cell queues towards the backplane. The same card SCT may be used for multiple cards of the same card type.
When an MPSM-T3E3-155 or MPSM-16-T1E1 card is powered up for the first time, the default card SCT file is used. The default SCT file is 0. You must run the cnfcdsct command in order to use another card SCT file.
Note
Use the following procedure to select a card SCT:

Note
Selecting a Port SCT
A port SCT defines queue parameters that apply to egress queues on a port. You can use the same port SCT for multiple ports. Port SCTs can be changed with connections provisioned on the port. However, the port needs to be administratively downed to effect this change. Hence this is service affecting.
Note
To select an SCT for an ATM port, enter the addport command as described in the "Adding ATM Ports" section of Chapter 3, "Provisioning ATM Services on MPSM-T3E3-155 and MPSM-16-T1E1."
To select an SCT for a Frame Relay port, enter the addport command as described in the "Provisioning Frame Relay Ports" section of "Provisioning Frame Relay Services on MPSM-T3E3-155 and MPSM-16-T1E1."
Note
Setting Up Lines
The first step in configuring MPSM-T3E3-155 and MPSM-16-T1E1 lines is to bring up and configure the physical lines that are connected to the switch. These topics describe how to do the following tasks:
Bringing Up Lines
Installing an MPSM-T3E3-155 card can add from 1 to 3 lines to your switch. Installing an MPSM-16-T1E1 card can add from 1 to 16 lines. You must bring up a line before you can configure the line or provision services on the line.
Before a line is brought up, or after it is brought down, the switch does not monitor the line. The port status light for the line flashes green, and all line alarms are cleared. The flashing green light means the line is unprovisioned.
When you bring up a line, the switch starts monitoring the line. The port status light is green when physical layer communications are established with a remote switch. If physical layer communications problems are detected, the port status light turns red, and alarms are reported.
Note
Note
Tip
To bring up a line on the switch, use the following procedure.
Step 1
Step 2
M8850_NY.7.PXM.a > cc <slotnumber>Replace <slotnumber> with the number of the slot in which the card is installed. Valid slot numbers are as follows:
•
•
Verify your card selection by viewing the switch prompt, which should list the slot number and the card type.
Step 3
M8850_NY.13.MPSM155[ATM].a > upln <bay.line>Replace <bay> with 1, and replace <line> with the number that corresponds to the back card port to which the line is connected, as shown in the following example:
M8850_NY.13.MPSM155[ATM].a > upln 1.1
Note

The line state is the administrative intent for the line. For example, a line is reported as Down until an administrator brings up the line. Once the administrator brings up the line, the line state remains Up until the administrator brings the line down with the dnln command.
The alarm state indicates whether the line is communicating with a remote switch. When the alarm state is reported as Clear, the physical devices at each end of the line have established physical layer communications. ATM or Frame Relay connectivity is established later when interfaces or ports are configured on the line.
Configuring DS1 (T1) Lines
All line types are brought up with a default configuration. When configuring trunks between two Cisco MGX switches, you may be able to accept the defaults for each switch and thus minimize configuration time. When configuring a line to another type of device, ensure that both devices are using the same configuration parameters on the shared line.
The following procedure describes how to configure T1 lines.
Step 1
Step 2
M8850_NY.13.MPSM16[FR].a > dsplnsRemember that you cannot configure a line until you have brought it up as described in the previous section, "Bringing Up Lines".

Table 2-4 lists the parameter descriptions for configuring E1 lines.
Step 5
Configuring DS3 (T3) Lines
All line types are brought up with a default configuration. When configuring trunks between two Cisco MGX switches, you may be able to accept the defaults for each switch and thus minimize configuration time. When configuring a line to another type of device, ensure that both devices are using the same configuration parameters on the shared line.
The following procedure describes how to configure T3 lines.
