Troubleshooting

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 the Access Security

Guide for your switch.

■ 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.
