After upgrading customer Brocade switches
to Fab os Version 7.0.1b, we followed the Release notes and installed Oracle
JRE 1.6.0 update 24 and webtools were running as expected without any issues. To
stay in accordance with the security standards, we upgraded the java version to
Oracle Java 7 update
51 and after that we were unable to open webtools neither in IE nor in
Google Chrome.
To troubleshoot the issue, the
first option was to check the installed JRE version and the best method was to issue command Java –version
Or dig in to registry and follow
below path
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JavaSoft\Java Runtime Environment
Restoring java version was not a solution as customer has strict orders to follow security practices. After doing research we came to know that latest Java release supports adding IP exceptions and we decided to try that.
To do that, you have to access
java control panel in windows as shown below
Once the Java control panel is available, access “security” tab and keep the security level High(as recommended). Go to Exception Site list and “Edit site list”
Insert your switch IP address (Webtools URL) and click “Add”.
Once done, open your browser, and try to access Webtools, there you go!.
If you have a better approach
for enabling Brocade webtools access do share it under comment section.
