Licensing issues
Some features need licenses in order to work properly. To view a list of features and their
associated licenses, refer to the Fabric OS Administrator’s Guide. Licenses are created using a
switch’s World Wide Name so you cannot apply one license to different switches. Before calling
your switch support provider, verify that you have the correct licenses installed.
Symptom A feature is not working.
Probable cause and recommended action
Refer to the Fabric OS Administrator’s Guide to determine if the appropriate licenses are installed
on the local switch and any connecting switches.
Determining installed licenses
1. Connect to the switch and log in using an account assigned to the admin role.
2. Type the licenseShow command.
A list of the switches currently installed licenses will be displayed.
Switch Message Logs
Switch message logs contain information on events that happen on the switch or in the fabric. This
is an effective tool in understanding what is going on in your fabric or on your switch. Weekly review
of these logs is necessary to prevent minor problems from becoming huge issues, or in catching
problems at an early stage.
Below are some common problems that can occur with or in your system message log.
