Preparing FRSM12 Cards and Lines for Communication
This chapter describes how to prepare FRSM12 cards for standalone or redundant operation in Cisco MGX Release 3 switches. Frame Relay Services for MGX Release 3.0 Switches describes how to provision these cards for Frame Relay communications across an ATM network.
This chapter provides a quickstart procedure for configuring FRSM12 cards and lines and describes the following procedures:
•Managing Firmware Version Levels for FRSM12 Cards
•Establishing Redundancy Between Two FRSM12 Cards
•Selecting and Viewing Service Class Templates
The quickstart procedure in this section provides a summary of the tasks required to prepare FRSM12 cards and lines to enable Frame Relay communications over an ATM network. This procedure is provided as an overview and as a quick reference for those who already have configured FRSM12 cards.
Start a configuration session.
Note To perform all the procedures in this quickstart procedure, you must log in as a user with GROUP1 privileges or higher.
setrev <slot> <version>
Initialize FRSM12 cards by setting the firmware version level for each FRSM12 card.
See "Managing Firmware Version Levels for FRSM12 Cards," which appears later in this chapter.
Define which FRSM12 cards are operating as redundant cards.
See "Establishing Redundancy Between Two FRSM12 Cards," which appears later in this chapter.
Applies communications parameters from a preconfigured Service Class Template (SCT) file to all communications between the card you are configuring and the other FRSM12 cards in the switch.
For PNNI communications, use SCT ID 2 or 4 for policing applications and use SCT ID 3 or 5 for non-policing applications. If MPLS will be used on any card link, use SCT ID 4 for policing applications and use SCT ID 5 for non-policing applications.
See "Selecting and Viewing Service Class Templates," which appears later in this chapter.
Managing Firmware Version Levels for FRSM12 Cards
The FRSM12 cards within the switch run two types of firmware: boot firmware and runtime firmware. The boot firmware provides the startup information the card needs. The boot firmware is installed on the board at the factory. The runtime firmware controls the operation of the card after startup. The runtime firmware file is stored on the PXM45 hard disk.
After the FRSM12 cards are installed in the switch, you must specify the correct runtime firmware version for each card before the switch can begin using the card. The following sections explain how to
•Locate the cards that need to have the firmware version level set
•Set the firmware version levels for cards in the switch
•Verify the firmware version levels being used by cards
Locating Cards that Need the Firmware Version Set
When an FRSM12 card is installed and the firmware version needs to be set, the System Status LED on the front of the card blinks red. The dspcds command shows that the card status is Failed. Other events can display these symptoms, but if the FRSM12 card is new, the problem is probably that the firmware version number has not been set. To locate the cards that need to have the firmware version set, use the following procedure.
Step 1 Establish a CLI management session at any access level.
Step 2 To display a list of all the cards in the switch, enter the dspcds command:
The following example shows the display for this command. The card state for the card in slot 4 is listed as Failed/Active. This is how a card appears when the runtime firmware version has not been selected.

Type <CR> to continue, Q<CR> to stop:
Note the slot number, card type, and redundancy type for each card that needs to have the firmware version set. You will need this information to activate these cards as described in the next section, "Initializing FRSM12 Cards."
Note If any FRSM12 card displays the Active/Active card state, you do not have to set the runtime firmware version for that card.
Initializing FRSM12 Cards
Before a FRSM12 card can operate, it must be initialized in a switch slot. The initialization process defines the FRSM12 runtime software version that will run on the card and identifies the slot in which the card operates. To initialize an FRSM12 card, use the following procedure.
Note The PXM45 card supports a maximum of 99 lines on the switch. As you add FRSM12 cards, verify that the line count for all AXSM and FRSM12 cards does not exceed this number.
Step 1 If you have not already done so, determine the software version number for the card by referring to the Release Notes for Cisco MGX 8850 and MGX 8830 Software Version 3 (PXM45/B and PXM1E).
Tip If you have trouble locating the runtime firmware version level, use the filenames on the PXM45 hard disk to determine the level. For more information, see "Determining the Software Version Number from Filenames," in Chapter 7, "Switch Operating Procedures."
Step 2 Establish a configuration session using a user name with SERVICE_GP privileges or higher.
Step 3 To set the firmware revision level for a card, enter the setrev command:
mgx8850a.7.PXM.a > setrev <slot> <version>
Note Each card should be initialized only once with the setrev command. The only other time you should enter the setrev command is to initialize cards after the configuration has been cleared with the clrallcnf, clrcnf, or clrsmcnf commands.
Replace <slot> with the card slot number and replace <version> with the software version number. For example,
mgx8850a.7.PXM.a > setrev 4 3.0(0)
After you enter the setrev command, the system status LED blinks red until the firmware load is complete, and then it changes to non-blinking green.
Step 4 To verify the activation of a card for which the status was previously listed as Failed/Empty, enter the dspcds command. The status should change to Active/Active.
Verifying Card Firmware Version Levels
When you are having problems with your switch, or when you have taken delivery of a new switch but delayed installation, it is wise to verify the firmware versions installed on the switch. If newer versions of this firmware are available, installing the updated firmware can prevent switch problems.
To verify the firmware versions in use on your switch, use the following procedure.
Step 1 To display the software revision status of all the cards in a switch, enter the dsprevs command as follows:
hsfrnd6.8.PXM.a > dsprevs
hsfrnd6 System Rev: 03.00 Feb. 15, 2002 06:19:35 GMT

11 11 FRSM12_12T3E3 3.0(0) 3.0(0)
Type <CR> to continue, Q<CR> to stop:
Step 2 To see the software revision levels for a single card, enter the dspversion command as follows:
hsfrnd6.4.FRSM12.a > dspversion
Image Type Shelf Type Card Type Version Built On

Runtime MGX FRSM12 3.0(0) Feb 14 2002, 19:46:30
Step 3 Another way to see the software revision levels for a single card is to enter the dspcd command as follows:
hsfrnd6.4.FRSM12.a > dspcd

Step 4 Using the dsprevs and dspcd commands, complete the hardware and software configuration worksheet in Table 2-8.
Step 5 Compare the versions you noted in Table 2-8 with the latest versions listed in the Release Notes for Cisco MGX 8850 and MGX 8830 Software Version 3 (PXM45/B and PXM1E).
Step 6 If the switch requires software updates, upgrade the software using the instructions in "Downloading and Installing Software Upgrades."
Establishing Redundancy Between Two FRSM12 Cards
To establish redundancy between two FRSM12 cards, use the following procedure.
Step 1 Establish a configuration session using a user name with SUPER_GP privileges or higher.
Step 2 If you have not done so already, set the firmware version for both cards, as described earlier in "Initializing FRSM12 Cards."
Step 3 Enter the dspcds command to verify that both FRSM12 cards are in the "Active" state.
Step 4 Enter the addred command as follows:
pop20one.7.PXM.a > addred <redPrimarySlotNum> <redSecondarySlotNum> <redType>
Replace <redPrimarySlotNum> with the slot number of the FRSM12 card that will be the primary card, and replace <redSecondarySlotNum> with the slot number of the secondary FRSM12 card. Replace <redType> with the number 1, which selects 1:1 Y-cable redundancy. Although the online help lists other redundancy types, 1:1 Y-cable redundancy is the only type supported on FRSM12 cards in this release.
Note One of the two cards can be configured before redundancy is established. If this is the case, the configured card should be specified as the primary card. Redundancy cannot be established if the secondary card has active lines. If the secondary card has active lines, you must delete all ports and down all lines before it can be specified as a secondary card. You clear the configuration on a single service module with the clrsmcnf command.
Tip If the switch displays the message,
ERR: Secondary cd is already reserved, then lines are already in use on the specified secondary card. Use the dnln command to bring down these lines before re-entering the addred command, or enter the clrsmcnf command for the secondary card.
Step 5 To verify that the redundancy relationship is established, enter the dspred command as shown in the following example:
pop20two.7.PXM.a > dspred
pop20two System Rev: 02.01 Feb. 06, 2001 11:24:53 PST
Primary Primary Primary Secondary Secondary Secondary Redundancy
SlotNum Type State SlotNum Type State Type
------- ------- --------- --------- --------- --------- ----------
1 FRSM12 Active 2 FRSM12 Standby 1-1
7 PXM45 Active 8 PXM45 Standby 1-1
15 SRM-3T3 Empty Res 16 SRM-3T3 Empty Resvd 1-1
31 SRM-3T3 Empty Res 32 SRM-3T3 Empty Resvd 1-1
The secondary state for the card in the secondary slot changes to Standby only when the secondary card is ready to take over as active card. After you enter the addred command, the switch resets the secondary card. When you first view the redundancy status, the state may be Empty Resvd or Init. The secondary card may require one or two minutes to transition to standby.
Note The dspcds command also shows the redundancy relationship between two cards.
For information on managing redundant cards, see the "Managing Redundant Cards" section in Chapter 7, "Switch Operating Procedures."
Selecting and Viewing Service Class Templates
The following sections describe how to select SCTs for cards and ports.
Selecting a Card SCT
A card SCT defines ATM parameters that apply to communications between the card you are configuring and the other service modules in the switch. You can use the same SCT for multiple FRSM12 cards. To select an SCT for a card, use the following procedure.
Step 1 Establish a configuration session using a user name with GROUP1 privileges or higher.
Step 2 Enter the following command:
pop20two.1.FRSM12.a > cnfcdsct <sctID>
Note When an FRSM12 card is powered up for the first time, the default card SCT file is used. You must run this command in order to use another SCT file. The default SCT file is 0.
Replace sctID with the number of the SCT that you want to assign to the card. For PNNI communications, use SCT ID 2 or 4 for policing applications and use SCT ID 3 or 5 for non-policing applications. If MPLS will be used on any card link, use SCT ID 4 for policing applications and use SCT ID 5 for non-policing applications.
Note For most applications, Cisco Systems recommends using non-policing card SCTs.
Step 3 To display the SCT assigned to a card, enter the following command:
pop20two.1.FRSM12.a > dspcd
The display card report displays a row labeled "Card SCT Id," which identifies the SCT assigned to the card.
Selecting a Port SCT
A port SCT defines ATM parameters that apply to communications through a single port. You can use the same port SCT for multiple ports. To select an SCT for a port, enter the addport command as described in Frame Relay Services for MGX Release 3.0 Switches.
