Fabric OS Administrator’s Guide 1-3
Publication Number: 53-0000518-09
Help Information
1
You can access switches from different connections, such as Web Tools, CLI, and API. When these
connections are simultaneous, changes from one connection might not be updated to the other, and
some modifications might be lost. When simultaneous connections are used, make sure that you do not
overwrite the work of another connection.
In a mixed fabric containing switches running various Fabric OS versions, you should use the latest-
model switches running the most recent release for the primary management tasks. The principal
management access should be set to the core switches in the fabric. For example, to run Secure Fabric
OS
®
, use the latest-model switch as the primary FCS, the location to perform zoning tasks, and the time
server.
A number of management tasks are designed to make fabric-level changes; for example, zoning
commands make changes that affect the entire fabric. When executing fabric-level configuration tasks,
allow time for the changes to propagate across the fabric before executing any subsequent tasks. For a
large fabric, it might be take a few minutes.
Help Information
Each Fabric OS command provides Help information that explains the command function, its possible
operands, its level in the command hierarchy, and additional pertinent information.
Displaying Command Help
To display help information:
1. Connect to the switch and log in as admin.
2. To display a list of all command help topics for a given login level, enter the help command with no
arguments. For example, if you are logged in as user and enter the help command, a list of all user-
level commands that can be executed will be listed. The same rule applies to the admin role. In
addition, any user-configured command that uses a switchAdmin role will also see commands
available to users with the switchAdmin role.
3. To display help for a specific command for a given login level, enter help command, where
command is the name of the command for which you need information
