Enterasys Networks CSX6000, CSX5500, CSX7000 manual IP Routing Over a WAN Direct Host Interface

USER’S GUIDE

4.If the remote IP host CANNOT ping to the CyberSWITCH, try the following:

a.Verify that the LAN interface is properly configured by using the ipnetif command (a Manage Mode command).

If the proper LAN interface does not exist, use CFGEDIT to make corrections.

b.Verify that the remote IP Host is initiating a call to the CyberSWITCH. Since the LAN interface has an IP address assigned with a different network number than the one for the remote IP Host, the remote IP Host may need a proper route entry for the local network where the CyberSWITCH is located. Make corrections to the remote IP Host configuration.

5.Determine if a remote IP host can access the local IP host through the system over the WAN connection. On the remote IP host type:

ping 100.0.0.2 <return>

If the remote IP host successfully pings to the local IP host, then IP routing over WAN type interface is operational. Repeat steps 1 through 5 for each WAN type interface through which you wish to get access.

6.If the remote IP host CANNOT ping to the local IP host, try the following:

a.Verify that the local IP Host has the route entry for the remote network with the CyberSWITCH as the next hop.

b.If the local IP Host has the proper route entry to the remote network, refer to LAN Connection in the Verifying Base System chapter.

c.If the local IP Host does not have the proper route entry, make corrections to the local IP Host configuration.

IP ROUTING OVER A WAN (DIRECT HOST) INTERFACE

To verify that IP routing is properly operational over a WAN (Direct Host) interface, a remote IP Host must be operational and available to initiate connections. Also, a local IP host must be connected to the local LAN port on the CyberSWITCH.

Below is an example of a configuration used to verify IP routing over a WAN (Direct Host) interface. It uses IP addresses specific to the example. Substitute the IP addresses of your network when you perform the IP routing verification steps. It also uses the “ping” command. The “ping” command sends a packet to a specified host, waits for a response, and reports success or failure. Substitute the equivalent command on your IP host.
