Network Diagnosis

With network diagnosis, you can quickly check whether the network between the CBH system and a managed host is connected if the managed host fails to be logged in. CBH can use any of the following methods to check the connectivity:

Ping the host IP address to check whether the CBH system communicates with the host over the ICMP protocol.
Perform route tracing on the host address to check whether the route between the CBH system and the host is reachable.
Perform the TCP port test on the host IP address to check whether the CBH system is connected to the TCP port on the host.

If the network is unreachable, rectify the fault.
If the network connectivity is normal, check whether the username, password, and port number of the host added to the system are correct.

This topic describes how to test the network connectivity.

Prerequisites

You have the management permissions for the System module.

Procedure

Log in to the CBH system.
Choose System > System Maintain > Network Diagnosis.

Ping the IP address of the host to check the network connectivity.
1. Set Infotype to ping.
2. Enter the host IP address and click Test to view the connectivity test result.
3. Check whether the system can communicate with the host using the ICMP protocol.
Traceroute the host IP address and check the network connectivity.
1. Set Infotype to traceroute.
2. Enter the host IP address and click Test to view the connectivity test result.
3. Check whether there is a reachable route between the system and the host.
Test network connectivity through the TCP port.
1. Set Infotype to TCP port.
2. Enter the host IP address and port number and click Test to view the connectivity test result.
3. Check whether the TCP port between the system and the host is reachable.
