IP R OUTING O VER A WAN R EMOTE LAN I NTERFACE
To verify that IP routing is properly operational over a WAN Remote LAN interface, a remote IP
Host must be operational and connected to the remote LAN. The remote bridge device 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 Remote LAN
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.
1. Determine if a remote IP host can access the WAN Remote LAN interface of the CyberSWITCH
over the WAN connection. On the remote IP host type:
ping 192.100.1.1 <return>
If the remote IP host successfully pings to the CyberSWITCH, continue with step 3.
2. If the remote IP host CANNOT ping to the CyberSWITCH, try the following:
a. Verify that the WAN connection is up. Use the mc console command to display the Monitor
Connections screen. Check for the connection. If the connection is NOT up, refer to Remote
Device Connectivity .
b. Verify that the WAN RLAN interface is properly initialized. Use the ipnetif command
(a Manage Mode command) to check for the proper WAN RLAN interface. If the proper
interface does NOT exist, use CFGEDIT to make the necessary corrections.
c. Check that the IP address configured in the Device list for the IP Host device matches the
address configured on the IP Host device. Make corrections to the CyberSWITCH’s
configuration (using the
iproute change Manage Mode command), or to the IP Host’s
configuration, as required.
