Small Office Remote Access Switch 373PROBLEM DIAGNOSISIP Host ModeIP H OST M ODEThe following sections provide diagnostic procedures for the IP Host Mode.IP HOST I NITIALIZATIONProblem:The system does not display the correct IP Host Initialization messages. Or, instead, it displays thefollowing message:[IP] IP Router is initialized successfullyAction: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 M ODE OPERATION OVER THE LAN CONNECTIONProblem:The system does not display the correct message after the ping command. Instead, it displays thefollowing message:No response from

Action:1. Verify that the routing entry for the destination network exists by entering the followingconsole command:iproute

2. If the command returns “No route is available for

“the routingentry does not exist. To correct, add the static routing entry using theiproute add ManageMode command.3. Check that the CyberSWITCH and the specified Host both have the same Subnet mask and Subnetwork number for that ip-address using theipnetif Manage Mode command. Correct theHost configuration, or the system configuration (using theiproute change Manage Modecommand) as required.4. Verify that the ARP entry for the specified IP address exists. As required, ping from the IP Hostso that the ARP entry is updated. Use theip arp command to look at the ARP cache entries.(This command is described in the System Commands chapter.) If the ARP cache entry for theHost does not exist, verify that the Host is operational and that the CyberSWITCH and the Hostare 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 encapsulationtype as the CyberSWITCH. The CyberSWITCH can receive and recognize either Ethernet orSNAP type encapsulations. Correct the IP Host or CyberSWITCH configuration (usingCFGEDIT) for encapsulation type.6. Try to ping the Host from another device on the LAN. If this is also unsuccessful, this mayindicate a problem with the Host.
