AUSM Card Management

AUSM Card Management

This chapter provides procedures for managing AUSM-8T1/Band AUSM-8E1 cards after the initial card setup and provisioning.

Note   Initial card setup is described in the Cisco MGX 8850 (PXM1E) and MGX 883Cisco MGX 8850 (PXM1E) and MGX 8830 Software Configuration Guide, Release 3. The provisioning of AUSM cards is described in "Provisioning Communications Links."

This chapter describes the following AUSM management procedures:

Managing CLI Sessions

Basic session initialization and management is described in the Cisco MGX 8850 (PXM1E) and MGX 883Cisco MGX 8850 (PXM1E) and MGX 8830 Software Configuration Guide, Release 3. Table 3-1 lists and describes the session management commands supported on the AUSM cards. For more information on these commands, see "AUSM Command Reference."

Managing Cards

Basic card initialization and configuration is described in the Cisco MGX 8850 (PXM1E) and MGX 883Cisco MGX 8850 (PXM1E) and MGX 8830 Software Configuration Guide, Release 3. The following sections provide procedures for doing the following:

Determining the Card Feature Set

The AUSM-8T1/B and AUSM-8E1/B cards can support ABR Rate Control and Inverse Multiplexing over ATM (IMA). To display the state of these feature options, enter the dspfeature command as shown in the following example:

PXM1E_SJ.1.21.AUSMB8.a > dspfeature Rate Control: On IMA feature: On PXM1E_SJ.1.21.AUSMB8.a >

The example above is for an AUSM-8T1/B card. To determine whether the card is an AUSM-8T1/B or an AUSM-8E1/B, use the dspcd or dspcds command.

Displaying General Card Information

To display general information about an AUSM card, use the dspcd command as shown in the following example:

PXM1E_SJ.1.21.AUSMB8.a > dspcd ModuleSlotNumber: 21 FunctionModuleState: Active FunctionModuleType: AUSM-8T1/B FunctionModuleSerialNum: 820581 FunctionModuleHWRev: ae FunctionModuleFWRev: 020.000.001.000-D FunctionModuleResetReason: Reset by PXM LineModuleType: LM-RJ48-8T1 LineModuleState: Present mibVersionNumber: 80 configChangeTypeBitMap: CardCnfChng, LineCnfChng cardIntegratedAlarm: Major cardMajorAlarmBitMap: Line Alarm ATM PORT ALARM cardMinorAlarmBitMap: Channel failure Type <CR> to continue, Q<CR> to stop: Front Card Info Hardware Revision : AE Card Type : 52 Serial Number : 820581 Fab Number : 28-2160-01 Back Card Info Hardware Revision : AA Card Type : 22 Serial Number : 773224 Fab Number : 28-2011-01 PXM1E_SJ.1.21.AUSMB8.a >

Note that the dspcd command displays information on card alarms.

Displaying Software Version and Status Information

To display information on the software running on a AUSM card, use the chkflash and version commands.

The chkflash command shows the status of the boot software:

PXM1E_SJ.1.21.AUSMB8.a > chkflash Program length = 377836 Calculated checksum = 3818c59a stored checksum = 3818c59a Flash checksum passed PXM1E_SJ.1.21.AUSMB8.a >

The version command displays the software versions running on the card:

PXM1E_SJ.1.21.AUSMB8.a > version ***** Cisco Systems Inc. AXIS AUSM-8T1/E1 Card ***** Firmware Version = 020.000.001.000-D Backup Boot version = AU8_BT_1.0.02 AUSM8p Xilinx file = ausm8pXilinx.h VxWorks (for CISCO) version 5.1.1-R3000. Kernel: WIND version 2.4. Made on Mon Jul 1 23:25:34 PDT 2002. Boot line: PXM1E_SJ.1.21.AUSMB8.a >

Managing Lines

"Provisioning Communications Links," describes how to bring up (add) and modify AUSM card lines. The following sections provide procedures for doing the following:

Displaying a List of Lines

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

PXM1E_SJ.1.21.AUSMB8.a > dsplns Line Conn Type Status/Coding Length XmtClock Alarm Stats Type Source Alarm ---- ----- ------------ ------ -------- ------------- -------- ----- ----- 21.1 RJ-48 dsx1ESF Ena/dsx1B8ZS 0-131 ft LocalTim Yes Yes 21.2 RJ-48 dsx1ESF Dis/dsx1B8ZS 0-131 ft LocalTim 21.3 RJ-48 dsx1ESF Dis/dsx1B8ZS 0-131 ft LocalTim 21.4 RJ-48 dsx1ESF Dis/dsx1B8ZS 0-131 ft LocalTim 21.5 RJ-48 dsx1ESF Dis/dsx1B8ZS 0-131 ft LocalTim 21.6 RJ-48 dsx1ESF Dis/dsx1B8ZS 0-131 ft LocalTim 21.7 RJ-48 dsx1ESF Dis/dsx1B8ZS 0-131 ft LocalTim 21.8 RJ-48 dsx1ESF Mod/dsx1B8ZS 0-131 ft LoopTimi No No LineNumOfValidEntries: 8 PXM1E_SJ.1.21.AUSMB8.a >

Display the Configuration for a Single Line

To display the configuration of a single line, enter the dspln command as follows:

PXM1E_SJ.1.21.AUSMB8.a > dspln <line>

Enter the line number with the command. You can view the available line numbers in the dsplns display. The following example shows the information you can display with the dspln command:

PXM1E_SJ.1.21.AUSMB8.a > dspln 8 LineNum: 8 LineConnectorType: RJ-48 LineType: dsx1ESF LineEnable: Modify LineCoding: dsx1B8ZS LineLength: 0-131 ft LineXmtClockSource: LoopTiming LineLoopbackCommand: NoLoop LineSendCode: NoCode LineUsedTimeslotsBitMap: 0xffffff LineLoopbackCodeDetection: codeDetectEnabled LineBERTEnable: Disable LineNumOfValidEntries: 8 PXM1E_SJ.1.21.AUSMB8.a >

Bringing Down a Line

When a line is not working properly, it generates a line alarm. If the line is going to be out-of-service for a long period of time and you want to suppress the alarm, you can bring down the line. Bringing down the line removes it from 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 and resource partitions are associated with ports in the respective display commands (dspcons and dsprscprtn), and ports are associated with lines (dspports). To determine which connections and resource partitions use a line, first determine which ports are configured for that line.

Step 2   Delete all resource partitions that are associated with the line (delrscprtn command).

Step 3   Delete all ports that are associated with the line (delport command).

Step 4   Enter the delln command as follows:

PXM1E_SJ.1.21.AUSMB8.a > delln <line>

Enter the line number with the command. You can view the available line numbers in the dsplns 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

The switch generates line alarms when problems occur. Use the following commands to display these alarms and alarm configuration parameters:

Use the following commands to clear alarms and alarm counts on lines:

Managing Ports

"Provisioning Communications Links," describes how to add logical ports to the lines on AUSM cards. The following sections provide procedures for doing the following:

Displaying a List of Ports

To display a list of ports on the current AUSM card, enter the dspports command as follows:

PXM1E_SJ.1.1.AUSMB8.a > dspports List of ATM ports: ================== Port PortType Line# Portenable Speed PortState ---- -------- ----- ---------- ----- --------- 1.5 NNI 5 UP 3622 Line alarm 1.6 NNI 6 UP 3622 Line alarm 1.7 UNI 7 UP 3622 Line alarm 1.8 UNI 8 UP 3622 Line alarm List of IMA groups: =================== ImaGrp PortType Conf Avail Lines configured Lines present Tol Diff Port State rate rate Delay(ms) ------ -------- ----- ----- --------------- --------------- --------- ---------- 1.1 NNI 14364 14364 1.2.3.4 1.2.3.4 275 Active NextPortNumAvailable: 4 ImaGrp Sync State ------ ---------- 1.1 Far-End Permanent Syntax : dspports PXM1E_SJ.1.1.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). To determine if a port is in alarm, check the status in the Port State column. For more information on a single port, use the dspport command.

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>

Enter the port number with the command. You can view the port numbers in the dspports 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 Lines configured : 1.2.3.4 Enable : Modify IMA Port state : Active IMA Group Ne state : operational PortSpeed (cells/sec) : 14364 GroupTxAvailCellRate (cells/sec) : 14364 ImaGroupTxFrameLength(cells) : 128 LcpDelayTolerance (IMA frames) : 1 ReadPtrWrPtrDiff (cells) : 4 Minimum number of links : 2 MaxTolerableDiffDelay (msec) : 275 Lines Present : 1.2.3.4 Observed Diff delay (msec) : 0 Clock Mode : CTC GroupAlpha : 2 GroupBeta : 2 GroupGamma : 1 GroupConfiguration : 1 IMAGrp Failure status : No Failure Timing reference link : 1 ImaGroupTxImaId : 0x0 ExpectedGroupRxImaId : 0x1 PXM1E_SJ.1.1.AUSMB8.a >

Deleting Ports

To delete an AUSM port, use the following procedure.

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.

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

Step 2   Delete all resource partitions that are associated with the port (delrscprtn command).

Step 3   Enter the delport command, as shown below.

PXM1E_SJ.1.1.AUSMB8.a > delport <port>

Replace the port parameter with the port number you want to delete. Port numbers are listed in the dspports command display.

Managing IMA Groups

"Provisioning Communications Links," describes how to create and configure IMA groups. The following sections provide procedures for doing the following:

Displaying a List of IMA Groups

To display a list of IMA groups on the current AUSM card, enter the dspimagrps command as follows:

PXM1E_SJ.1.1.AUSMB8.a > dspimagrps List of IMA groups: =================== ImaGrp PortType Conf Avail Lines configured Lines present Tol Diff Port State rate rate Delay(ms) ------ -------- ----- ----- --------------- --------------- --------- ---------- 1.1 NNI 14364 14364 1.2.3.4 1.2.3.4 275 Active 1.2 NNI 14364 0 5.6.7.8 275 Sig. Failure NextPortNumAvailable: 5 PXM1E_SJ.1.1.AUSMB8.a >

Displaying the Configuration for a Single IMA Group

To display the configuration of a single IMA group, enter the dspimagrp command as follows:

PXM1E_SJ.1.21.AUSMB8.a > dspimagrp <group_num>

Enter the group number with the command. You can view the available group numbers in the dspimagrps display. The following example shows the information you can display with the dspimagrp command:

PXM1E_SJ.1.1.AUSMB8.a > dspimagrp 1 IMA Group number : 1 Port type : NNI Lines configured : 1.2.3.4 Enable : Enabled IMA Port state : Active IMA Group Ne state : operational PortSpeed (cells/sec) : 14364 GroupTxAvailCellRate (cells/sec) : 14364 ImaGroupTxFrameLength(cells) : 128 LcpDelayTolerance (IMA frames) : 1 ReadPtrWrPtrDiff (cells) : 4 Minimum number of links : 3 MaxTolerableDiffDelay (msec) : 275 Lines Present : 1.2.3.4 Observed Diff delay (msec) : 0 Clock Mode : CTC GroupAlpha : 2 GroupBeta : 2 GroupGamma : 1 GroupConfiguration : 1 IMAGrp Failure status : No Failure Timing reference link : 1 ImaGroupTxImaId : 0x0 ExpectedGroupRxImaId : 0x0 PXM1E_SJ.1.1.AUSMB8.a >

Adding Lines to an IMA Group

To add one or more lines to an IMA group, use the addlns2imagrp command as follows:

PXM1E_SJ.1.1.AUSMB8.a > addlns2imagrp <group_num> <list_of_lines>

Table 3-2 describes the parameters for this command.


Table 3-2: Parameters for addlns2imagrp and dellnsfmimagrp Commands
Parameter Description

group_num

Enter the number for the IMA group you want to modify. Use the dspimagrps command to display the configured IMA groups.

list_of_lines

List the lines to be included in the group. Separate each line number by a period. For example, 1.2.3.4 adds lines 1 through 4 to the IMA group.

The following example shows how to add a single line to an IMA group.

PXM1E_SJ.1.1.AUSMB8.a > addlns2imagrp 1 8 PXM1E_SJ.1.1.AUSMB8.a >

The next example shows how to add multiple lines to an IMA group.

PXM1E_SJ.1.1.AUSMB8.a > addlns2imagrp 1 7.8 PXM1E_SJ.1.1.AUSMB8.a >

Deleting Lines from an IMA Group

To delete one or more lines from an IMA group, enter the dellnsfmimagrp command as follows:

PXM1E_SJ.1.1.AUSMB8.a > dellnsfmimagrp <group_num> <list_of_lines>

Table 3-2 describes the parameters for this command.

Note   Deleting a line from an IMA group reduces the available throughput for the group and may impact ATM traffic through the group. Also, the switch does not allow you to delete lines when the resulting number of lines would be less than the minimum number of lines specified for group operation. To change the minimum number of lines for an IMA group, use the cnfimagrp command.

The following example shows how to delete a single line from an IMA group.

PXM1E_SJ.1.1.AUSMB8.a > dellnsfmimagrp 1 8 Warning: If Connections exist under the ima group then the cell rates might require modification PXM1E_SJ.1.1.AUSMB8.a >

The next example shows how to delete multiple lines from an IMA group.

PXM1E_SJ.1.1.AUSMB8.a > dellnsfmimagrp 1 7.8 Warning: If Connections exist under the ima group then the cell rates might require modification PXM1E_SJ.1.1.AUSMB8.a >

Deleting an IMA Group

To delete an IMA group, use the following procedure.

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

Tip The port number shown in the dspcons display is the IMA group number.

Step 2   Delete all resource partitions that are associated with the IMA group (delrscprtn command).

Step 3   Enter the delimagrp command as follows:

PXM1E_SJ.1.21.AUSMB8.a > delimagrp <group_num>

Enter the group number with the command. You can view the available group numbers in the dspimagrps display. The following example shows how to use the delimagrp command:

PXM1E_SJ.1.1.AUSMB8.a > delimagrp 1 PXM1E_SJ.1.1.AUSMB8.a >

Managing Resource Partitions

Resource partitions define how port resources are distributed between two or more controllers. This software release supports only the PNNI controller, so all port resources are assigned to PNNI when a port or IMA group is added. This resource assignment is automatically made by the software and results in the creation of a resource partition for the port.

During normal operation, you will not need to add a resource partition. You can view the resource partition configuration, make changes to it, or delete it. If you delete a resource partition, you will have to create a new partition for that port before you can assign connections to the port.

The following sections describe how to view, add, modify, and delete resource partitions.

Displaying a Resource Partition Configuration

To display the resource partition configuration for a port, enter the dsprscprtn command as follows:

PXM1E_SJ.1.1.AUSMB8.a > dsprscprtn <port>

Replace the port parameter with the ATM port or IMA group number. For example:

PXM1E_SJ.1.1.AUSMB8.a > dsprscprtn 1 Port User NumOfLcn VPI VPID VCI IngrBW EgrBW CtrlrId Low/High Low/High Low/High ---- ----- -------- -------- --------- ------------ ------ ----- ------- 1 PNNI 1000 0 / 255 1 / 1000 0 / 65535 100 100 2 PXM1E_SJ.1.1.AUSMB8.a >

Adding a Resource Partition

To add a resource partition to a port, enter the addrscprtn command as follows:

PXM1E_SJ.1.1.AUSMB8.a > addrscprtn <port_num> <cntrlr_type> <pct_bw_ingr> <pct_bw_egr> <low_vpi> <high_vpi> <low_vci> <high_vci> <low_vpid> <high_vpid> <max_lcn> <cntrlr_id>

Table 3-3 lists and describes the parameters for the addrscprtn command.


Table 3-3: Parameters for the addrscprtn and cnfrscprtn Commands
Parameter Description

port_num

Port number to be partitioned. You must add a port to a line before you can define a partition for a port. Use the dspports command to view the available ports.

cntrlr_type

Controller for this partition. Enter 2 as the PNNI controller is the only controller type supported in this release.

  • PAR = 1

  • PNNI = 2

  • MPLS = 3

pct_bw_ingr

Ingress bandwidth percentage. Enter the percentage of the line bandwidth to be used by this controller for ingress communications. Range is 1 to 100 percent.

pct_bw_egr

Egress bandwidth percentage. Enter the percentage of the line bandwidth to be used by this controller for egress communications. Range is 1 to 100 percent.

low_vpi

Enter the minimum VPI number to allow for connections using the specified controller type (cntrlr_type) on this port. The range is from 0 to 255.

high_vpi

Enter the maximum VPI number to allow for connections using the specified controller type (cntrlr_type) on this port. The range is from 0 to 255.

low_vci

Enter the minimum VCI number to allow for connections using the specified controller type (cntrlr_type) on this port. The range is from 0 to 65535.

high_vci

Enter the maximum VCI number to allow for connections using the specified controller type (cntrlr_type) on this port. The range is from 0 to 65535.

The following example adds a resource partition to a port after the default partition was deleted.

PXM1E_SJ.1.1.AUSMB8.a > addrscprtn 1 2 100 100 0 255 35 65535 1 1000 1000 2 PXM1E_SJ.1.1.AUSMB8.a >
Tip Several specifications reserve VCI values in the range of 0 through 35. If you are not familiar with these specifications and want to avoid potential conflicts, set the lower VCI value to 35.

Modifying a Resource Partition

To modify a resource partition for a port, enter the cnfrscprtn command as follows:

PXM1E_SJ.1.1.AUSMB8.a > cnfrscprtn <port_num> <cntrlr_type> <pct_bw_ingr> <pct_bw_egr> <low_vpi> <high_vpi> <low_vci> <high_vci> <low_vpid> <high_vpid> <max_lcn> <cntrlr_id>

Table 3-3 lists and describes the parameters for the cnfrscprtn command.

The following example changes the default lower VCI value to 35 and leaves all other resource partition values set to the default values.

PXM1E_SJ.1.1.AUSMB8.a > cnfrscprtn 1 2 100 100 0 255 35 65535 1 1000 1000 2 PXM1E_SJ.1.1.AUSMB8.a >
Tip Several specifications reserve VCI values in the range of 0 through 35. If you are not familiar with these specifications and want to avoid potential conflicts, set the lower VCI value to 35.

Deleting a Resource Configuration

To delete the resource partition configuration for a port, use the following procedure.

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

Tip The port number shown in the dspcons display is the resource partition number.

Step 2   Enter the delrscprtn command as follows:

PXM1E_SJ.1.1.AUSMB8.a > delrscprtn <port> <cntrlr_type> <cntrlr_id>

The parameters for this command are described in Table 3-3. The following example deletes a PNNI partition assigned to port 1:

PXM1E_SJ.1.1.AUSMB8.a > delrscprtn 1 2 2 PXM1E_SJ.1.1.AUSMB8.a >

Managing Connections

"Provisioning Communications Links," describes how to add connections to AUSM cards. The following sections provide procedures for doing the following:

Displaying a List of Connections

To display a list of connections on the current AUSM card, enter the dspcons command as follows:

PXM1E_SJ.1.4.AUSMB8.a > dspcons LCN Port VPI VCI Class Type M/S EgrQ Admin Alarm ---- ---- --- ----- ------- ----- --- ---- ----- ----- 0016 001 100 00100 CBR1 VCC S 1 Up PORT-ALARM 0017 002 100 00100 CBR1 VCC M 1 Up PORT-ALARM Number of channels: 2 ChanNumNextAvailable : 18 Local VpId NextAvailable : 1 PXM1E_SJ.1.4.AUSMB8.a >

To determine if a connection is in alarm, check the status in the Alarm column. For more information on a single port, use the dspcon command.

Display the Status of a Single Connection

To display the configuration and status of a single connection, enter the dspcon command as follows:

PXM1E_SJ.1.4.AUSMB8.a > dspcon <port_num.vpi.vci>

Enter the connection port number, VPI, and VCI with the command. You can view the port, VPI, and VCI numbers in the dspcons display. The following example shows the dspcon report for connection 100/100 on port 1:

PXM1E_SJ.1.4.AUSMB8.a > dspcon 1.100.100 ------------------------------------------- ChanNum: 16 RowStatus: Add AdmnState: Up ChanState: Failed ---------- ---------- ---------- ---------- PORT-ALARM CTRLR-ABIT E-AIS/RDI I-AIS/RDI ---------- ---------- ---------- ---------- YES YES NO NO ------------------------------------------- ChanNum: 16 RowStatus: Add ConnAdminStatus: Up ConnectionType: VCC ServiceType: CBR1 ChanSvcFlag: PNNI PortNum: 1 VPI: 100 VCI (For VCC): 100 Local VPId(for VPC): 0 EgressQNum: 1 IngressQDepth(cells): 1000 IngressDiscardOption: CLP hysterisis IngressFrameDiscardThreshold 1000 IngressQCLPHigh(cells): 900 IngressQCLPLow(cells): 800 QCLPState: LOW IngressEfciThreshold(cells): 1000 UPCEnable: Enabled PeakCellRate[0+1](cells/sec): 3591 CellDelayVariation[0+1]: 10000 (micro secs) PeakCellRate[0](cells/sec): 3591 CellDelayVariation[0]: 250000 (micro secs) SustainedCellRate(cells/sec): 10 MaximumBurstSize(cells): 1024 SCRPolicing: CLP[0] CLPTagEnable: Enabled FrameGCRAEnable: Disable InitialBurstSize(cells): 0 LocalRemoteLpbkState: Disable ChanTestType: No Test ChanTestState: Not In Progress ChanRTDresult: 65535 ms Ingress percentage util: 100 Egress percentage util : 100 Egress Service Rate: 3591 LocalVpi: 100 LocalVci: 100 LocalNSAP: 4700918100000000016444445c00000101230100 RemoteVpi: 0 RemoteVci: 0 RemoteNSAP: 0000000000000000000000000000000000000000 Mastership: Slave VpcFlag: Vcc RoutingPriority: 8 MaxCost: 2147483647 RestrictTrunkType: No Restriction LocalConnPCR: 3591 LocalConnSCR: 10 LocalConnMCR: 10 RemoteConnPCR: 3591 RemoteConnSCR: 10 RemoteConnMCR: 10 LocalConnMBS: 1024 RemoteConnMBS: 1024 Chan Reroute: False ConnPercentUtil: 100 ChanOvrSubOvrRide: Enabled Stdabr Parameters: Minimum Cell Rate: 10 Cells per second Peak Cell Rate: 10 Cells per second Initial Cell rate: 10 Cells per second Rate Increase Factor: 64 Rate Decrease Factor: 16 Nrm -- Inrate Cell Count: 64 Trm -- Time limit for Frm: 255 milliseconds Transient Buffer Exposure: 16777215 Cells Fixed Round Trip Time: 0 milliseconds ACR Decrease Time Factor: 500 milliseconds Cutoff Decrease Factor: 16 AbrType: Switch behavior without VS/VD ChanNumNextAvailable : 18 Local VpId NextAvailable : 1 PXM1E_SJ.1.4.AUSMB8.a >

Deleting Connections

Each connection (or SPVC) has two endpoints. To completely delete a connection, you need to delete both endpoints. To delete an AUSM connection endpoint, enter the delcon command, as shown below.

PXM1E_SJ.1.4.AUSMB8.a > delcon <port_num.vpi.vci>

Enter the connection port number, VPI, and VCI with the command. You can view the port, VPI, and VCI numbers in the dspcons display.

The delcon command deletes the SPVC connection endpoint on the local switch. Note, however, that this command does not delete the remote end of the SPVC. The remote end of the SPVC must be deleted by issuing a delcon command on that switch.

Testing a Connection

The tstcon and tstdelay commands perform short tests that verify that the switch can communicate with both ends of the connection.

Testing with tstcon

The tstcon command checks to see if the switch can communicate with both ends of the connection. To test an AUSM connection with the tstcon command, enter the command as follows:

PXM1E_SJ.1.4.AUSMB8.a > tstcon <port_num.vpi.vci>

Enter the connection port number, VPI, and VCI with the command. You can view the port, VPI, and VCI numbers in the dspcons display. The following is an example of a tstcon test:

PXM1E_SJ.1.4.AUSMB8.a > tstcon 1.100.100 PXM1E_SJ.1.4.AUSMB8.a > TestCon in progress. TestCon Passed.

Testing with tstdelay

The tstdelay command checks to see if the switch can communicate with both ends of the connection, and it returns a measurement of the delay across the connection. To test an AUSM connection with the tstdelay command, enter the command as follows:

PXM1E_SJ.1.4.AUSMB8.a > tstdelay <port_num.vpi.vci>

Enter the connection port number, VPI, and VCI with the command. You can view the port, VPI, and VCI numbers in the dspcons display. The following is an example of a tstdelay test:

PXM1E_SJ.1.4.AUSMB8.a > tstdelay 1.100.100 PXM1E_SJ.1.4.AUSMB8.a > TestDelay in progress. TestDelay Passed with 1 ms. PXM1E_SJ.1.4.AUSMB8.a >
