Backup Equalizer Continuously Reboots
Primary and Backup Equalizer Are in a Conflict over Primary
Certain Dell and Cisco switches have Spanning Tree enabled by default. This can cause a delay in
the times that the network is accessible and cause the backup unit to enter into failover mode. If
you cannot disable Spanning Tree, enable PortFast for all ports connected to the ADCs.
Can’t View the GUI
GUI not enabled
Services flags at the global and subnet level control availability of the GUI. It must be enabled
globally and on at least one subnet in order to be accessible. Access the GUI using the subnet IP
address on which either of the HTTP or HTTPS services is enabled.
ADC is not active
Try to
ping
the administration address. If you do not get a response, see “Equalizer doesn’t
respond to pings to the admin address” below, which provides additional troubleshooting
information.
Browser cache needs to be cleared
After an upgrade, the GUI may need to be completely reloaded before it can be used again,
depending on the level of change to the GUI code contained in the upgrade. You can do this by
clearing your browser cache; or, closing your browser and opening it again to establish a new
connection.
Equalizer Doesn’t Respond to Pings to the Admin Address
Equalizer is not powered on
Check that power switch is on and the front panel LED is lit. Connect the keyboard and monitor,
cycle the power, and watch the startup diagnostic messages.
Equalizer isn't connected to your network
Check the network wiring.
Use diagnostic tools to check connectivity and routing
See
on page 759 for a list of the diagnostic tools available in the CLI.
Packets from the Server Aren’t Routed Correctly
IP spoofing is enabled
This problem normally occurs in a single network setup. When you enable IP spoofing, clustered
servers see the client’s IP address. If the server tries to reply directly to the client, the client will
reject the reply (it had sent its request to a different address).
Run a
traceroute
to ensure that routes from a server to a client go through Equalizer and not
directly back to the client. If Equalizer does not appear, modify the route to include Equalizer.
Alternatively, you can disable IP spoofing.
