Problem Resolution
Cannot connect using the
Web browser. • Be sure you have configured the agent with a valid IP
address, subnet mask and default gateway.
• If you are trying to connect to the agent via the IP
address for a tagged VLAN group, your management
station must include the appropriate tag in its
transmitted frames.
• Check that you have a valid network connection to the
switch.
• Check network cabling between the management
station and the switch.
