Send a ping, traceroute, or DNS lookup
request to an IP address or host name
You can you take the following actions independently of each other or simultaneously
(or rather, one after the other):
• Send a ping: The switch sends a fixed number of ping requests to a particular IP
device to determine if it can communicate with the device.
• Send a traceroute: The switch attempts to trace the route to a particular IP device
to determine the precise path to the device.
• Send a DNS lookup request: The switch contacts DNS servers to determine the IP
address that is associated with a host name.
When you run one or more tests, the test results are displayed in the panes onscreen.
To send a ping, traceroute, or DNS lookup request to an IP address or host name:
1. Launch a web browser.
2. In the address field of your web browser, enter the IP address of the switch.
The login page displays.
3. In the Login Name field, enter admin as the user name, in the Password field, enter
your local device password, and click the AV UI Login button.
The first time that you log in, no password is required. However, you then must
specify a local device password to use each subsequent time that you log in.
The Overview page displays.
