Web UI is Sluggish, Does Not Refresh Properly, or Does Not Respond
When configuring the controller, it is easy to overlook the fact that the host computer is running the
browser while the Brocade RF Series Controller is providing the data to the browser. Occasionally,
while using the Web UI the controller does not respond or appears to be running very slow; this
could be a symptom of the host computer or the network, and not the controller itself. The table
below provides suggestions to troubleshoot this issue.
Possible Problem
Bad connection between
controller and console
system
Slow transmission of data
packets
Access points may try to
adopt while country code is
not set
Packet storm
Overburdened with a large
number of Access Points
Java JRE is out of date
Cannot access Web UI
through a Firewall
All else...
Console Port is Not Responding
The Brocade RF Series Controller console port is connected to the host computer's serial port, but
pressing the [Enter] key gets no response from the controller.
The table below provides suggestions to troubleshoot this issue.
Possible Problem
Cabling issue
Not using a terminal
emulation program

Suggestions to Correct
Verify the line between the controller and the host computer is functioning
normally
Verify the data packets are being sent to and from the controller using a sniffer
tool
Set the country name for the controller, which is set to "none" by default
Check Syslog for any type of a packet storm
With large numbers of Access Points, changing the configuration quickly may
cause the controller to not refresh properly, at least immediately following
configuration.
Be sure you are using Sun Java JRE 1.5 or later. To download the appropriate for
your system go to: http://www.sun.com/java/
To successfully access the controller Web UI through a firewall, UDP port 161
must be open in order for the controller's SNMP backend to function
Contact Brocade Support
Suggestions to Correct
Ensure a console cable is connected from the console port to the host computer's
serial port
Verify a serial terminal emulation program, such as HyperTerminal, is in use on
the host computer
