USER’S GUIDE

Each section below uses example entries to verify IP Host mode operation. IP addresses are specific to the examples. Substitute the IP addresses of your network when you perform the IP Host mode feature verification steps. Each section also uses the ip ping command. The ip 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.

VERIFICATION OVER A LAN CONNECTION

1.Determine if the CyberSWITCH can access the local IP host. Type: ip ping 100.0.0.2

2.If a message similar to the following is displayed, the IP host mode feature over the specified LAN port is operational. Repeat this step for each LAN port on your Ethernet resource.

100.0.0.2is alive

3.You may have a problem if you receive the message:

No response from <ip-address>

Try the following:

a.Verify that the routing entry for the destination network exists by entering the following console command:

iproute <ip-address>

b.If the command returns “No route is available for <ip-address>”,the routing entry does not exist. To correct, add the static routing entry using the iproute add Manage Mode command.

c.Check that the CyberSWITCH and the specified Host both have the same Subnet mask and Sub network number for that ip-address using the ipnetif Manage Mode command. Correct the Host configuration, or the system configuration (using the iproute change Manage Mode command) as required.

d.Verify that the ARP entry for the specified IP address exists. As required, ping from the IP Host so that the ARP entry is updated. Use the ip arp command to look at the ARP cache entries. (This command is described in the System Commands chapter.) If the ARP cache entry for the Host does not exist, verify that the Host is operational and that the CyberSWITCH and the Host are both physically connected to the same LAN segment.

e.If the ARP cache entry exists for the Host, check that the IP Host has the same encapsulation type as the CyberSWITCH. The CyberSWITCH can receive and recognize either Ethernet or SNAP type encapsulations. Correct the IP Host or CyberSWITCH configuration (using CFGEDIT) for encapsulation type.

f.Try to ping the Host from another device on the LAN. If this is also unsuccessful, this may indicate a problem with the Host.

g.Verify that the hardware address (MAC address) for the IP Host in the CyberSWITCH’s ARP cache is correct. If it is not correct, verify the configuration in the IP Host.
