PINGing Your IP Address
By sending a packet to the specified address and waiting for a reply, the PING utility can determine
whether a specific IP address is accessible. It also provides a particularly useful method for
confirming addressing conflicts with your AXIS 2120 on the network.
Having disconnected your AXIS 2120, follow the instructions below in association with Symptoms,
Possible Causes and Remedial Actions, on page 52, and run the PING utility to troubleshoot TCP/IP
problems on your network:
1. Start a DOS window.
2. Type ping x.x.x.x , where x.x.x.x is the IP address of the AXIS 2120.
3. The subsequent replies will provide an explanation as to the cause of the problem. Replies can
be interpreted as defined in the table below:
