Using Network Troubleshooting Tools
Using the Network Troubleshooting Tools, you can check the health of your network and troubleshoot problems. This tool is composed of several utilities that allow you to test the integrity of you network. The following table describes the utilities that make up the Network Utilities tool.
Table 1. Network Utilities
Name | Using this tool you can... | How… |
Ping | Tests whether a specific Host is accessible across the
network. | In the Address field, type the IP
address that you want to test. Press
ENTER. |
TCPing | Tests whether a specific TCP port on a Host is
accessible across the network. | In the Address field, type the IP
address. In the Port field, type the
port number. Select OK. |
TraceRoute | Tests the path of a packet from one machine to another.
Returns timing information and the path of the packet. | At the prompt, type the IP address or Host name of the
destination machine. Select
OK. |
MTR | Tests the path of a packet and returns the list of
routers traversed and some statistics about each. | At the prompt, type the IP address or Host
name. Select OK. |
TCPDump | Tests network traffic, and examines all packets going
through the machine. | To filter information, by network interface, protocol,
Host, or port, type the criteria in the corresponding text
boxes. Select OK. |
SysLog | Sends syslog messages. Can be used to test syslog
connectivity. | In the Address field, enter the
IP address of the remote machine the syslogs will be sent
to. In the Port field, enter a port
number the remote machine is listening to. In the
Message field, enter a test message. Select
OK. On the remote machine, check if
the syslog was successfully sent. Note that the appliance
uses UDP syslog, so there is no way to validate whether the syslog
server is accessible. |
Show MAC | Finds out the MAC address for a given IP address.
Detects IP collision. | At the prompt, type the IP address or Host
name. Select OK. |
