Before you can begin to use the CWSI application, the devices in your network must be set up correctly. If your network contains ATM devices, you must configure LANE services to extend connectivity to each device in the ATM fabric so the discovery process can recognize ATM devices.
Table 2-1 lists the steps involved in setting up CWSI. Detailed procedures follow the summary.
This section provides detailed steps for each of the procedures described in Table 2-1. Perform the following major tasks in sequence:
You need to upgrade your switch software to the latest version. See the CWSI release note for the correct version information for each device.
You need to configure your switches or verify the configuration of your switches so they can support CWSI.
You can configure the switches using the CLI on each switch or use Telnet from the CWSI Network Map>Tools menu.
Step 1 Enable Cisco Discovery Protocol on all switches in the network by entering the following command on all switches:
set cdp enable all
Step 2 Verify that your switches are running the correct system software versions. Refer to the release notes that accompanied your CWSI product for this information.
Step 3 If your network includes switches that support VLAN Trunk Protocol, configure the VTP management domain using the following command on the switch:
set vtp domain name
Replace name with the name of your management domain.
Step 4 Check that VTP is enabled (the default setting) on all switches that support VTP.
Step 5 If a switch is connected to Fast Ethernet links and you want to configure it to carry more than one VLAN, verify that Inter-Switch Link is enabled on both sides of the link.
Step 6 If your network contains ATM devices, create a default configuration server at each device in your ATM fabric using the device CLI.
On devices that support VTP, enabling VTP on the ATM module automatically creates a default Client for the device.
LightStream 1010 switches need a default configuration server only if the Ethernet port is not used. If you create a Client on a LightStream 1010 switch, you need to assign an IP address to the switch.
After you start the CWSI application, you will perform additional configuration from the CWSI interface to set up the default LANE services.
Step 7 Verify that the network management station on which CWSI is running has IP connectivity to each switch. Ping each switch to verify this. If you have an ATM network, connect the ethernet port of an LS1010 to the management station running CWSI to make it network accessible.
Step 8 Determine the read and write community strings for your switches. If they differ from "public" for the read-only string and "public" for the read-write string, enter the correct strings when prompted during installation, or edit the community string file after you install CWSI so that the community strings on the switches match the CWSI community strings.
Install the CWSI software following the instructions in the booklet that shipped with your CD-ROM. The CWSI application software installation is prompt driven and you need enter only the name of your seed device. The seed device can be any Cisco device on your network. It must have CDP enabled and a valid read community string for the device.
If your network has ATM devices use a LightStream 1010 switch that is located next to a Catalyst 5000 as the seed device.
To start CWSI, follow these steps:
Step 1 Start CWSI using the appropriate procedure for the platform on which you are running it.
For example, from Windows NT, from the Start menu, select Programs>CWSI.
The CWSI Login window opens with a default username. No password is required.
Step 2 Click OK to accept the default and continue.
The CWSI Map window displays the discovered network map, which includes all reachable discovered devices. A cloud indicates unreachable ATM devices.
If your network includes one or more ATM devices or links, you need to establish a default ATM-VLAN to allow SNMP connectivity within the ATM fabric and to allow VTP advertisements to propagate throughout the ATM fabric.
To configure a default ATM-VLAN, follow these steps:
Step 1 From the CWSI Map window, select Tools> VlanDirector. The VlanDirector main window opens.
Step 2 From the VlanDirector Names window, select Edit>Configure Default ATM-VLAN.
The Configure Default ATM-VLAN window opens.
Step 3 Click Configure.
Step 4 From the CWSI Map window select View>Rediscover Map to rediscover the network including the ATM fabric.
After the discovery has completed, the CWSI Map window displays the ATM devices.
