PROBLEM DIAGNOSIS

IP Host Mode

IP HOST MODE

The following sections provide diagnostic procedures for the IP Host Mode.

IP HOST INITIALIZATION

Problem:

The system does not display the correct IP Host Initialization messages. Or, instead, it displays the following message:

[IP] IP Router is initialized successfully

Action:

1.Check the configuration. Make sure that the IP feature is enabled.

2.Make sure that the operating mode is set to Host rather than Router.

IP HOST MODE OPERATION OVER THE LAN CONNECTION

Problem:

The system does not display the correct message after the ping command. Instead, it displays the following message:

No response from <ip-address>

Action:

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

iproute <ip-address>

2.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.

3.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.

4.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.

5.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.

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