Troubleshooting 58
The port activity LEDs continuously indicate activity
after connecting more than one port to another
switch or destination device
Action:
Because there are multiple links across this device and the destination device, they form loops, which
cause broadcast storms. Enable STP for multiple links. This setting prevents loops and maintains standby
links for resilience in case of primary link failure.
Cannot connect to the switch remotely using the
Web interface
Action:
• The switch IP address is not configured or correct.
o From the serial console interface, be sure that the switch IP address is configured and valid on
the network.
o Use the correct IP address to establish the Web connection with the switch.
• Access to the switch using the Web interface is disabled. From the serial console interface, be sure
that the Web interface is enabled.
• The Proxy server settings are configured on the Internet browser and the proxy server does not know
the switch IP address. Disable the manual proxy settings on the Web browser and let it automatically
find Web servers using the IP address.
• The management network address/mask (if used) does not contain the IP address of the
management station. From the serial console interface, be sure that the management network
address/mask contains the IP address of the management station.
Cannot enable a port in multiple VLANs while
configuring VLANS
Action:
A port is part of only one VLAN unless the port is a tagged port. Be sure that the port is enabled as a
tagged port.
