Browser or Telnet Access Problems

Cannot access the web browser interface:

■

Access may be disabled by the

Web Agent Enabled parameter in the switch

console. Check the setting on this parameter by selecting:

2. Switch Configuration . . .

1. System Information

■

The switch may not have the correct IP address, subnet mask or gateway.
Verify by connecting a console to the switch’s Console port and selecting:

2. Switch Configuration . . .

5. IP Configuration

Note:

If DHCP/Bootp is used to configure the switch, the IP addressing

can be verified by selecting:

1. Status and Counters . . .

2. Switch Management Address Information

also check the DHCP/Bootp server configuration to verify correct IP
addressing.

■

If you are using DHCP to acquire the IP address for the switch, the IP
address “lease time” may have expired so that the IP address has changed.
For more information on how to “reserve” an IP address, refer to the
documentation for the DHCP application that you are using.

■

If one or more IP-Authorized managers are configured, the switch allows
web browser access only to a device having an authorized IP address. For
more information on IP Authorized managers, see Chapter 10, “Using
Authorized IP Managers for Increased Management Security”.

■

Java™ applets may not be running on the web browser. They are required
for the switch web browser interface to operate correctly. See the online
Help on your web browser for how to run the Java applets.
