8. Is the number of cells received increasing?

•If no, go to step 6.

•If yes, continue.

9. Convert Allocated Bandwidth (kb/s) to cells (48 bytes).

Bandwidth in cells = (1024 X Allocated Bandwidth) / 384

where 384 = 48 cells X 8

10. Is the Allocated Bandwidth less than the Cell Reception Rate?

•If no, go to step 6.

•If yes, this VC is misbehaving. Take appropriate action, for example, terminate the VC.

Create an ELAN on your switch by executing the add elan command. The following is an example: 3. Create a client for the switch on the ELAN. For example, enter 5. Physically connect your end nodes and edge devices to the switch ports. Note When you create a client, it automatically finds the LECS address using ILMI. 4. Enter the show client command to make certain that the client is operational.

Use set vccmask to change the VPI/VCI values to 3/9. Note Do not set the VCI part of the VCCMask to fewer than 5 bits. 2. Use the show vccmask command to see the new VPI/VCI combination. 3. Use the set portconfig command to reconfigure a port to use the new values for VPI and VCI. For example, to set up a PVC on port A1 using the new VPI/VCI bit ranges (3/9), enter 4. Use show portconfig to see the change to port A1. PVCs can be configured for port A1 using VPI values from 0 to 7 and VCI values from 0 to 511. 4.6 TRAFFIC MANAGEMENT Page 4.6.2 Call Admission Control Policy 4.6.3 Class of Service Queues Class of Service Queue Allocation Guidelines 4.6.4 EFCI, EPD, and RM Thresholds Page 5 TROUBLESHOOTING 5.1 TROUBLESHOOTING IP OVER ATM - - - - - - - - - - - 5.2 TROUBLESHOOTING LAN EMULATION - - - - - - - - - - 5.3 TROUBLESHOOTING CONGESTION 5.3.3 Port Con estion Page Page APPENDIX A FEATURES AND SPECIFICATIONS A.1 HARDWARE COMPONENTS A.1.1 Front Panel Fi g A.1.2 CPU Module A.1.3 Switch Modules (MSM and ESM) A.1.4 Input/Output (Port) Modules 155 Mbps STS-3c/STM-1 UTP5, 4 Ports 155 Mbps STS-3c/STM-1 SMF/MMF, 4 Ports MMF, 4 Ports 155 Mbps STS-3c/STM-1 Port Numberin A.2 FEATURES Page A.3 SPECIFICATIONS A.3.1 Technical Specifications A.3.2 Physical Specifications A.3.3 ATM Port Specifications A.3.4 Standards Specifications A.3.5 CPU Serial Port Pin-Out Descriptions Page Page APPENDIX B SMARTCELL 6A000 AND SNMP B.1 INTERNET MIB HIERARCHY B.2 ZEITNET PROPRIETARY MIB tt B.2.1 Interpretin the Object Identifier B.2.2 Proprietary MIB Functions B.3 A CLIENT FOR SNMP MANAGEMENT B.4 CONSOLE COMMANDS THAT AFFECT THE AGENT B.5 MIB EXCEPTIONS Page Page Page APPENDIX C TECHNICAL SUPPORT C.1 TELEPHONE ASSISTANCE C.2 FAX SERVICE C.3 ELECTRONIC SERVICES C.4 PLACING A SUPPORT CALL C.5 HARDWARE WARRANTY C.6 SOFTWARE WARRANTY C.7 REPAIR SERVICES APPENDIX D ACRONYMS A B C D E F G H I J K L M N O P Q R S T U V W Page INDEX A B C D L M O P Q T U V W
