Note The dspcd command displays the integrated card alarm.

To determine whether a card is an AUSM-8T1/B, AUSM-8E1/B, MPSM-8T1-ATM, or MPSM-8E1-ATM card, enter the dspcd command on the AUSM or MPSM card, or use the dspcds command on the PXM1, PXM1E, or PXM45 controller card.

Displaying Software Version and Status Information

Enter the chkflash and version commands to display information on the software running on an AUSM or MPSM card. The chkflash command shows the status of the boot software, and the version command displays the software versions running on the card.

The following example shows the status of the boot software on an AUSM card:
PXM1E_SJ.1.21.AUSMB8.a > chkflash

Displaying AUSM Card Features

Enter the dspfeature command to display the features supported on AUSM cards. The AUSM-8T1/B and AUSM-8E1/B cards support ABR Rate Control and Inverse Multiplexing over ATM (IMA). Enter the dspfeature command as shown in the following example to display whether Rate Control and/or IMa are enabled on the current AUSM card:
PXM1E_SJ.1.21.AUSMB8.a > dspfeature
  Rate Control:  On
  IMA feature:  On
PXM1E_SJ.1.21.AUSMB8.a >
Managing MPSM Feature Licenses

Some features on the MPSM-8T1E1 card are enabled by the use of feature licenses. These feature licenses reside on the PXM processor in a license pool until needed by the MPSM card.

The following sections provide procedures for doing the following:

•Displaying MPSM Feature Licenses

•Moving MPSM Feature Licenses

•Allocating MPSM Feature Licenses

•Managing MPSM Feature License Alarms

Note To install spare feature licenses into the PXM license pool, transfer feature licenses from one switch to another switch, and rekey feature licenses, refer to the Cisco MGX 8800/8900 Series Configuration Guide, Release 5.2 and the Release Notes for Cisco MGX 8230, Cisco MGX 8250, and Cisco MGX 8850 (PXM1) Switches, Release 1.3.12.

Displaying MPSM Feature Licenses

Use the dspliccd command to display the details of feature licenses that are needed, that have been allocated from the PXM license pool, or that have been programmed into the NVRAM of the MPSM-8T1E1 card.

Because the MPSM-8T1E1 card configured for ATM services does not require any feature licenses, the dspliccd command is used exclusively to view feature licenses that have been programmed into the NVRAM of the MPSM-8T1E1 card.

Note The rate control feature license is the only feature license available for the MPSM-8T1E1 card. This feature license is used by the MPSM-8T1E1 card when configured for Frame Relay services.

In the following example, the displiccd command shows one rate control feature license programmed into the NVRAM on the MPSM-8T1-ATM card:
M8850_SF.1.28.MPSM8T1.ATM.a > dspliccd
Card License Alarm:              None
Service Module Type:             MPSM8T1E1

License registration node:       NONE
License registration chassis:    NONE
=========================================================
M8850_SF.1.28.MPSM8T1.ATM.a > 
If a feature license is moved to the PXM license pool, then the Programmed License Registered field in the output of the dspliccd command will state YES. Notice in this example that the rate control license programmed into the NVRAM on the MPSM-8T1-ATM card has not been moved to the PXM license pool.

Moving MPSM Feature Licenses

If a feature license is purchased at the same time as the MPSM card, that license can be programmed into the NVRAM on the MPSM card. When a feature license is programmed on an MPSM card, the license is unavailable to that MPSM card and all other cards on the switch. To enable use of the programmed feature license, it must be moved from the MPSM card and installed in the switch license pool, which is a database on the PXM processor card.

The movelic command is used to move feature licenses programmed on MPSM cards to the switch license pool on the PXM processor card.

To move feature licenses, perform the following steps:

Step 1 Enter the dspliccd command to view the feature licenses that have been programmed on the MPSM card:
M8850_SF.1.28.MPSM8T1.ATM.a > dspliccd
Card License Alarm:              None
Service Module Type:             MPSM8T1E1
Service Module Serial Number:    SAG07208RRA
Provisioning (addcon) Allowed:   YES

License registration chassis:    NONE
=========================================================
M8850_SF.1.28.MPSM8T1.ATM.a > 
In this example, the output of the dspliccd command shows that one Rate Control feature license has been programmed into the NVRAM on the MPSM card.

Step 2 Enter the movelic command to move the feature licenses programmed on the MPSM card to the switch license pool on the PXM processor card:
M8850_SF.1.28.MPSM8T1.ATM.a > movelic
------------------------------------------------
Programmed License Type          #Programmed
-----------------------          -----------
RateControl                       1
Do you want to proceed (Yes/No)? y
Card Licenses have been moved to license pool.
M8850_SF.1.28.MPSM8T1.ATM.a >
After the feature licenses are moved from the MPSM card and installed in the switch license pool on the PXM processor card, the feature licenses are available for use by the MPSM cards installed in that switch

Step 3 When feature licenses are moved from the NVRAM on the MPSM card to the PXM license pool, the process is also referred to as registration of licenses with the switch.

Enter the dspliccd command to verify feature license registration into the switch license pool:
M8850_SF.1.28.MPSM8T1.ATM.a > dspliccd
Card License Alarm:              None
Service Module Type:             MPSM8T1E1

License registration chassis:    SCA062300GF
=========================================================
M8850_SF.1.28.MPSM8T1.ATM.a > 
This example shows that the Rate Control feature license has been registered, the name of the switch where the license has been registered, and the chassis serial number of the switch where the feature license has been registered.

Step 4 Enter the dsplics command on the PXM processor card to view the MPSM feature licenses installed in the PXM license pool:
M8850_SF.8.PXM.a > dsplics
M8850_SF                         System Rev: 05.00   Aug. 05, 2004 09:12:39 GMT

MPSM-8T1E1         RateControl  1          0          1 
M8850_SF.8.PXM.a > 
In this example, one Rate Control feature license has been successfully moved from the MPSM-8T1E1 card into the PXM license pool.

Allocating MPSM Feature Licenses

To allocate a feature license to an MPSM card, configure the card to use the licensed feature.

For example, to assign a channelized feature license to an MPSM card, enter the addport command and use the channelization parameters to channelize the line. If the license pool on the PXM has an available license for that feature and MPSM card type, that license is automatically assigned to the card and the feature is successfully configured.

If you try to configure an MPSM card to use a feature for which no licenses are available, the configuration attempt will fail. Once a license is assigned to an MPSM card, it is no longer available for use by other MPSM cards until it returns to the license pool.

Note•Because the MPSM-8T1E1 card configured for ATM services does not require any feature licenses, no feature licenses are allocated from the PXM license pool for any features or services configured on the MPSM-8T1-ATM or MPSM-8E1-ATM cards.

•The rate control feature license is the only feature license available for the MPSM-8T1E1 card. This feature license is used by the MPSM-8T1E1 card when configured for Frame Relay services.

Managing MPSM Feature License Alarms

MPSM feature license alarms can occur at the node level or the slot level of the switch. The following sections describe these alarms:

•Node License Alarm

•Slot License Alarms

Note Because the MPSM-8T1E1 card configured for ATM services does not require any feature licenses, no feature licenses alarms will be raised on the MPSM-8T1-ATM or MPSM-8E1-ATM cards. The following sections are useful in alerting the user to MPSM feature license alarm conditions that may occur for MPSM-8T1E1 cards configured for Frame Relay services.

Node License Alarm

Node license alarms can happen under the following conditions:

•A switch configuration that was saved before licenses were added or transferred to and from the PXM license pool has been restored. Any mismatch between the actual license count and the restored license count generates a minor license alarm. To prevent this type of alarm, always save the switch configuration after you move, transfer, or add licenses.

•The switch configuration is restored on a different node, or the Cisco MGX chassis is replaced with another chassis. Because licenses are authorized for a specific backplane serial number, such conditions will cause a mismatch between the physical backplane serial number and serial number recorded in the database.

When a node license alarm is raised, all cards that are using feature licenses go into the slot license alarm state. If no licenses are in use by the cards, no slot license alarms will be raised.

On PXM45 and PXM1E platforms, use the PXM dspndalms command to troubleshoot the node license alarm. On PXM1 platforms, use the PXM dspcd command to troubleshoot the node license alarm.

Node license alarms are cleared by validating licenses in the license pool. This is done by applying the special Rekey feature license to the node using the cnflic command. When the pool licenses are validated, any existing slot license alarms are also cleared and normal operation is restored. For the procedure to rekey feature licenses, see the Cisco MGX 8800/8900 Series Configuration Guide, Release 5.2 and the Release Notes for Cisco MGX 8230, Cisco MGX 8250, and Cisco MGX 8850 (PXM1) Switches, Release 1.3.12.

Note If the switch is in node license alarm, you must rekey the PXM license pool before proceeding with any other license management tasks.

Slot License Alarms

Slot license alarms are raised under the following conditions:

•When a node license alarm is raised, all cards that are using feature licenses go into the slot license alarm state. Slot license alarms raised under this condition are cleared by rekeying the PXM license pool.

•The slot in alarm has acquired or oversubscribed one or more licenses while these licenses were not available in the license pool. For example, on the PXM1 platform this situation might occur when a card is configured to use licenses, the card slot configuration is removed with the PXM clrsmcnf command, the licenses are assigned to another card, and then the card slot configuration is restored. Slot license alarms raised under this condition are cleared by adding the required number of licenses to the PXM license pool or by releasing corresponding licenses from other slots so that they become available to the slot in alarm. If slots in alarm have redundancy, you must add licenses to cover both the primary and secondary slots to clear the alarms.

On the PXM card, use the dsplicalms and dspliccd <slot> commands to troubleshoot slot license alarms. On the MPSM card, use the dspcd and dspliccd commands to troubleshoot slot license alarms.

For the procedures to rekey feature licenses, recover feature licenses, and add feature licenses to the PXM license pool see the Cisco MGX 8800/8900 Series Configuration Guide, Release 5.2 and the Release Notes for Cisco MGX 8230, Cisco MGX 8250, and Cisco MGX 8850 (PXM1) Switches, Release 1.3.12.

Note If the switch is in node license alarm, you must rekey the PXM license pool before proceeding with any other license management tasks.

When the switch is in slot license alarm, you have a grace period of 5 days (120 hours) to resolve the alarm(s). During the first 4 days (96 hours), traps are sent every 24 hours. For the final 24 hours of the grace period, traps are sent every hour of operation. If the alarms do not get cleared, the following actions are taken:

•An event is logged indicating the expiration of the grace period for a given slot needing license(s).

•A trap is sent hourly indicating the expiration of the grace period.

•The addcon command is blocked on the slot in license alarm until the license alarms are cleared.

When the PXM license pool has been rekeyed or licenses have been added to the PXM license pool, provisioning is restored and the switch exits the license alarm state.

Managing Lines

"Preparing AUSM and MPSM Lines and Ports for Communications," describes how to bring up (add) and modify AUSM and MPSM card lines. The sections follow provide procedures for performing the following line management tasks:

•Displaying a List of Lines

•Display the Configuration for a Single Line

•Bringing Down a Line

•Managing Line Alarms

Note This section provides procedures for some of the most common line management commands. For a complete list of line management commands, refer to Table 6-3 in Chapter 6, "AUSM and MPSM Command Reference."

Displaying a List of Lines

To display a list of lines on the current AUSM or MPSM card, enter the dsplns command as follows:

Display the Configuration for a Single Line

To display the configuration of a single line on an AUSM or MPSM card, enter the dspln command as follows:
PXM1E_SJ.1.21.AUSMB8.a > dspln <line>
Replace <line> with the number of the line you want to display.

Note You can view all available line numbers in the dsplns command display.

The following example shows the information you can display with the dspln command on an AUSM card:

PXM1E_SJ.1.21.AUSMB8.a >
Bringing Down a Line

When a line is not working properly, it generates a line alarm.If you want to suppress the alarm and you do not have time to correct the problem, you can bring down the line. Bringing down the line takes it out of service, so no alarms are generated.

Tip You can reduce the level of an alarm on a failed line from major to minor by using the addlnloop command to place the line in local loopback mode. This does not completely eliminate the alarm, but it does reduce the severity and allow you to preserve the configured resources for that line.

To bring down a line, use the following procedure.

Step 1 Delete all connections that are associated with the line (dspcons and delcon commands).

Tip Connections are associated with ports (dspcons), and ports are associated with lines (dspports). To determine which connections use a line, first determine which ports are configured for that line.

Step 2 Delete all ports that are associated with the line (delport command)

Step 3 Enter the delln command as follows:
PXM1E_SJ.1.21.AUSMB8.a > delln <line>
Replace <line> with the number of the line you want to delete.

Note You can view all available line numbers in the dsplns command display.

The following example shows how to use the delln command:
PXM1E_SJ.1.21.AUSMB8.a > delln 8
PXM1E_SJ.1.21.AUSMB8.a >
Managing Line Alarms

AUSM and MPSM cards generate line alarms when problems occur. When a loss of signal (LOS) alarm is detected, an AUSM or MPSM card notifies the connected CPE in the upstream direction after an integration period. The AUSM or MPSM card then continues to emit cells at the nominal rate but sets the ATM cell payload with an appropriate data pattern as specified by the ATM Forum ANSI T1.231 specification. Also, an OAM cell with RDI code goes to the far end to indicate out-of-service. The significance of the different types of alarms appears in Table 5-2.

Note When the line is in alarm, a line alarm trap is sent. There are no separate traps sent for the ports or for the connections that go into alarm due to the line alarm. Similarly when the port is in alarm, the port alarm trap is sent, and no separate traps are sent for the connections that go into alarm due to the port alarm.

Managing Ports

"Preparing AUSM and MPSM Lines and Ports for Communications," describes how to add logical ports to the lines on AUSM and MPSM cards. The sections that follow provide procedures for doing the following tasks:

•Displaying a List of Ports

•Displaying the Status of a Single Port

•Deleting Ports

Displaying a List of Ports

To display a list of ports on the current AUSM or MPSM card, enter the dspports command as follows:
M8830_CH.1.13.AUSMB8.a > dspports
  List of ATM ports:
  ==================
  Port PortType Line# Portenable  Speed  PortState                
  ---- -------- ----- ----------  -----  ---------                
  13.2  NNI      1    UP           3622  Line alarm               
 List of IMA groups:
 ===================
ImaGrp PortType Conf  Avail  Lines configured  Lines present  Tol Diff  Port State
                rate  rate                                    Delay(ms)           
------ -------- ----- -----  ---------------  --------------- --------- ----------
 13.1   UNI     10773     0  2.3.4                             275      Sig. Failure
  NextPortNumAvailable:  7
M8830_CH.1.13.AUSMB8.a >
The port list is divided into two lists: one of ATM ports and one for IMA groups (which are ATM ports using multiple lines). The port number is found in the Port column, in the format slot.port. To determine if a port is in alarm, check the status in the Port State column.

Displaying the Status of a Single Port

To display the configuration and status of a single port, enter the dspport command as follows:
PXM1E_SJ.1.1.AUSMB8.a > dspport <port>
Replace <port> with the number of the port you want to display.

Note You can view the port numbers in the dspports command display.

The following example shows the dspport display for ATM port 8.
PXM1E_SJ.1.1.AUSMB8.a > dspport 8
  LogicalPortNumber:             8
  Port Enable:                   UP
  Port State:                    Line alarm
  PortType:                      UNI
  PhysicalPortNumber:            8
  CellFraming:                   ATM
  CellScramble:                  No Scramble
  Plpp Loopback:                 No Loopback
  Single-bit error correction:   Disabled
PXM1E_SJ.1.1.AUSMB8.a >
The next example shows the report for an ATM port number that is assigned to an IMA group. This is the same report that appears when you enter the dspimagrp command.
PXM1E_SJ.1.1.AUSMB8.a > dspport 1
   IMA Group number                 : 1
   Port type                        : NNI

   ExpectedGroupRxImaId             : 0x1   
PXM1E_SJ.1.1.AUSMB8.a >
Deleting Ports

To delete an AUSM or MPSM port, use the following procedure.

Step 1 Delete all connections that are associated with the port (dspcons and delcon commands).

Step 2 Enter the delport command as follows to delete the port:
PXM1E_SJ.1.1.AUSMB8.a > delport <port>
Replace the <port> parameter with the port number you want to delete.

Note All port numbers on the current card are listed in the dspports command display.

Tip When a port is deleted, the resource partition associated with that port is also deleted at the same time. Therefore, it is not necessary to delete the port resource partition prior to deleting the port.

The following example shows how to use the delport command:
M8830_CH.1.13.AUSMB8.a > delport 1
M8830_CH.1.13.AUSMB8.a > 
Note You cannot use the delport command to delete a port number used by an IMA group. To delete an IMA group, use the delimagrp command.

Monitoring Port Statistics

Use the commands in table Table 5-5 to display and clear AUSM and MPSM port statistics. These commands enable the user to monitor the traffic being transmitted to and received from attached end-user equipment.
