3 IP OVER ATM AND LANE This chapter describes working with the SmartCell 6A000 IP over ATM VLAN and emulated LAN capabilities. At the end of this chapter you will be able to use your SmartCell 6A000 switch to • • Create an IP over ATM VLAN Create an emulated Ethernet LAN (LANE) 3.1 CREATING AN IP OVER ATM VLAN This section describes implementing IP over ATM on your SmartCell 6A000 switch. The following assumptions are made: • • • The 6A000 switch will have a client on the IP over ATM VLAN 1.
%•F"›amV˜"m˜,6˜p¦F•˜":1˜=/"2 3. ˜˜,6˜3¦F•˜":1˜"m=˜/"2' Enter the show client command to make sure the client is operational and to obtain the 20-byte ATM address of the ARP server. For instance, if you used the client number (client 1) from the example in step 2, enter the following command.
,6˜3¦F•˜":1˜"m=˜/"2' Note %•F"›amV˜"m˜'h¤d"›F=˜/"2˜˜ If configured devices fail to join the VLAN, see Chapter 4, Section 4.2.2, “UNI Routes.” Also, see Chapter 5, Section 5.1, “Troubleshooting IP Over ATM.” You have completed the process for creating an IP over ATM VLAN. Continue to the next section for instructions on creating an emulated LAN or go to Chapter 4, “Switch Administration,” for information about SmartCell 6A000 switch operations and maintenance. 3.1.

The default format is constructed as follows: netprefix + the MAC address of the device + a Selector Byte Where the netprefix is constructed from 39 + nine zero bytes + the last three bytes of the switch’s MAC address The Selector Byte specifies to whom the ATM address belongs.
,6˜3¦F•˜":1˜"m=˜/"2' %•F"›amV˜"m˜'h¤d"›F=˜/"2˜˜ This is analogous to a phone company that supports a communication system. Even though the phone company maintains the circuits, a call to the phone company itself cannot be made unless the phone company has its own number and connection on its own phone system. Similarly, VLAN membership (and the reachability) of a SmartCell 6A000 on any particular VLAN depends upon whether the SmartCell 6A000 has a local client connection for that VLAN.

4 SWITCH ADMINISTRATION This chapter contains software and hardware procedures that you might need to perform on your SmartCell 6A000 switch. These procedures include • • • • • • • • Backing up switch configuration Creating routes and connecting switches Using switch events and alarms Creating PVC connections Managing switch traffic Using low-level boot load switch commands Upgrading switch software Saving switch core dumps to a TFTP server 4.
ATM Routing Switch Administration The switch stores the IP address of the TFTP server, the path, and the backup file name. The next time you enter the or restore commands, these values are presented as the default IP address and path. For example, when you enter the restore command, the following display appears: backup SmartCell ZX# restore switch ServerIP(90.1.1.100) : Path(/back_dir/config-1) : SmartCell ZX # Backup file is valid.
Switch Administration 4. Enter the add ATM Routing ATMRoute command to create a static route to the IISP device: SmartCell ZX # add atmroute PortNumber(A1) : b2 AtmAddress() : 52:00:00:00:00:00:00:00:00:00:14:51:80 PrefixLength(104) : Index(0) : Type(Internal) :exterior Scope(0) : MetricsTag(0) : SmartCell ZX # Note 5. Enter the show The add ATMRoute command allows you to specify a set of metrics to be used with the route. For more on metrics and metric tags, see Section 4.2.3 “Route Metrics.
ATM Routing Switch Administration Note Dotted lines in the diagrams below represent one-way routes to the devices pointed to by the arrowheads. Each route is defined on the device from which the dotted line originates. A B LEC Physical link C IISP route IISP Domain PNNI Domain LECS Figure 4-1 IISP route across PNNI domain A second IISP device (Switch D) is added behind Switch A.
Switch Administration 4.2.2 ATM Routing UNI Routes Use the add ATMRoute command to create UNI routes. For example, connect an end station adapter (with MAC address 00:11:22:33:44:55) to port A2 of the SmartCell 6A000. If the adapter does not support ILMI or its ILMI is incompatible with the SmartCell 6A000, you must create a static UNI route between the adapter and port A2 of the SmartCell 6A000. 1.
ATM Routing 4.2.3 Switch Administration Route Metrics Route metrics are assigned to routes using a metric tag (one of the input parameters for add ATMRoute). The metric tag specifies a particular pair of incoming and outgoing metrics contained within a list of metrics. Metrics are created using the add PNNIMetric command. Each metric pair specifies a set of values that describe a route’s Service Category, cell rates, bandwidth, and administrative weight.
Switch Administration Enter show PNNIMetric IP Routing to view the newly created metric pair: SmartCell ZX # show pnnimetrics Metrics(ALL) : Metrics Metrics Tag Direction Index GCAC CLP Admin Wt Service Categories ================================================================================ 1 0x9 Incoming 0x10 CLP0+1 200 CBR 2 0x9 Outgoing 0x10 CLP0+1 200 CBR 3 0x111113 Outgoing 0x1 CLP0+1 5040 UBR 4 0x111113 Outgoing 0x2 CLP0+1 5040 ABR 5 0x111113 Outgoing 0x4 CLP0 5040 NRTVBR 6 0x111113 Outgoing
IP Routing Switch Administration Note SmartCell 6A000 IP routing performance is inadequate for routing between VLANs. If you need to create routes between VLANs on your SmartCell 6A000, use a router equipped with an ATM interface. Consult Cabletron Customer Support for recommended routers. For example, • • • • • • Switch SW1 and the NMS are on an Ethernet network with address 128.205.99.0. The IP address of SW1's Ethernet port is 128.205.99.254. The IP address of SW1's LANE client is 90.1.1.254.

Events and Alarms 4.4.2 Use the show Switch Administration Viewing Events and Alarms events command to view a list of the currently logged events.
Switch Administration Use the show alarms PVC Connections command to view a list of the currently logged alarms.
PVC Connections 4.5.1 Switch Administration Point-to-Point PVCs The procedure for setting up a PVC connection between two end nodes through the SmartCell 6A000 consists of specifying the ports and the virtual path and virtual channel identifiers (VPI and VCI). 1.
Switch Administration 1. PVC Connections Use add trafficdescriptor to create two new traffic descriptors, one for the forward direction, the other for the backward direction. For this example, for the forward traffic descriptor, we select UBR and accept the defaults.
PVC Connections 6. Switch Administration Configure the workstations for the same subnet and VPI/VCI pair = 0/101. The broadcasting workstation on port A1 can send traffic to the receiving workstations on ports B2, B3, and C1. 4.5.3 Connecting to Local Switch Client Through a PVC All PVC connections to the SmartCell 6A000 local clients use B4 (the CPU port) as the HighPort. Follow these instructions to connect an end node to a SmartCell 6A000 local client through a point-to-point PVC. 1.

Switch Administration 4.6 Traffic Management TRAFFIC MANAGEMENT This section describes how the SmartCell 6A000 manages bandwidth and congestion. It briefly describes console commands that affect how the SmartCell 6A000 manages traffic. This section also provides guidelines for setting some traffic control parameters. Note For information on troubleshooting traffic congestion problems, see Chapter 5, “Troubleshooting.” The SmartCell 6A000 has extensive abilities for managing the flow of traffic.
Traffic Management Switch Administration Use the trafficdescriptor commands to view, create, and delete traffic descriptors. For example, enter the show trafficdescriptor command to view all currently defined traffic descriptors.
Switch Administration Traffic Management A user-defined PVC must have user-defined traffic descriptors. For instance, if a video link over a PVC requires a constant data flow of 5000 kb/s and a peak cell rate of 8000 kb/s, create a traffic descriptor for CBR traffic that specifies 5000 as the sustained cell rate and 8000 as the peak cell rate.
Traffic Management Use the command show referenced by VPI.
Switch Administration For example, enter the show Traffic Management porttrafficcongestion command to view current buffer utilization.
Traffic Management Switch Administration Quality of Service Queue Allocation Guidelines The following values are recommended settings for the Min and Max thresholds for the QoS queues under specific sustained traffic conditions. Use the settings in Table 4-3 as guidelines for threshold settings.
Switch Administration Upgrading and Changing Software Along with EFCI and backward RM cell marking, the SmartCell 6A000 uses standard RM cell marking. The switch discard threshold (show switchtrafficcongestion) corresponds to total shared buffer utilization and represents the point at which the switch considers itself congested and starts marking RM cells. Note The switch discard threshold is not user configurable and is shown only for information.
Upgrading and Changing Software 4.7.2 Switch Administration Boot Load Commands The following table describes the commands available from the boot load prompt, their use, and their associated parameters. Table 4-4 Boot load commands Command Action Parameters chpi Change default boot load image: chpi 0 = set boot load image 0 as default Sets one of two images of the boot load software as the default. Default boot load image is executed at start-up.
Switch Administration Upgrading and Changing Software Image is downloaded into boot PROM by df b chpi sets which is the default boot image initial boot routines boot image 0 POST is downloaded into flash RAM by df p ponf turns POST on and off.
Upgrading and Changing Software 5. Switch Administration Set up the TFTP/Bootp server tables (or equivalent file) with: - SmartCell 6A000 MAC address IP address of the SmartCell 6A000 Ethernet interface path to the image file on the TFTP/Bootp server 6. From the terminal connection, enter the reboot command. 7. When the following message appears, “Press any key to exit to boot load prompt.” stop the countdown by pressing any key. The boot load prompt (=>) appears on the terminal screen. 8.
Switch Administration Upgrading and Changing Software Changing the Default Boot Load Image Continuing with the example above, perform the following steps to set boot load image 0 back to being the default. 1. Reboot the SmartCell 6A000. 2. When the following message appears “Preparing to run Default Primary Image: 1 Enter 0 or 1 to override and force one of these primary image sectors to run:” press the zero (0) key. The SmartCell 6A000 loads boot load image 0. 3.

Saving Core Dumps Switch Administration If the problem is corrected, enter the update firmware command to continue with the upgrade process. However, if you are unable to correct the problem, use the df (download flash) command and a TFTP/Bootp server to replace the operating software on your SmartCell 6A000. Follow the procedure outlined below: 1. Set up TFTP/Bootp server software on a workstation. 2. Connect both the TFTP/Bootp server and the SmartCell 6A000 to your Ethernet network.
Switch Administration Enter the set Saving Core Dumps CoreDump command to enable the core dump feature. For example, SmartCell ZX # set coredump EnableCoreDump(n) ServerIP() CoreDumpFile() userName() UserPassword() SmartCell ZX # : : : : y 204.95.77.240 /tftpboot/bobr/core bobr : < “y” to enable core dump feature < IP address of my TFTP server < full path name for core dump files < login name on the server < password Note The set CoreDump command uses FTP to create the core_cpu and core_cmn files.
Saving Core Dumps Switch Administration If a system failure occurs while the core dump feature is enabled, the SmartCell 6A000 console appears similar to the example below. The SmartCell 6A000 then begins sending images of its memory to the core dump files on the TFTP server. Illegal access. Bus Error.
