If you disable SNMP in the Cisco MDS switch, you cannot configure FICON parameters using the Fabric

Manager.
To configure SNMP control of FICON parameters using Fabric Manager, follow these steps:
Choose VSAN > FICON.
Step 1
You see a list of switches under the Control tab in the Information pane.
Click the VSANs tab.
Step 2
You see the FICON VSAN configuration information in the Information pane (see
Step 3
Check the Port Control By SNMP checkbox to allow SNMP users to configure FICON on the switch.
Step 4
Click the Apply Changes icon to save these changes.
FICON Information Refresh
When viewing FICON information through the Device Manager dialog boxes, you must manually
refresh the display by clicking the Refresh button to see the latest updates. You need to take this step
whether you configure FICON through the CLI or through the Device Manager.
There is no automatic refresh of FICON information. This information would be refreshed so often that
it would affect performance.
About FICON Device Allegiance
FICON requires serialization of access among multiple mainframes, CLI, and SNMP sessions be
maintained on Cisco MDS 9000 Family switches by controlling device allegiance for the currently
executing session. Any other session is denied permission to perform configuration changes unless the
required allegiance is available.
This task discards the currently executing session.
Caution
Automatically Saving the Running Configuration
Cisco MDS NX-OS provides an option to automatically save any configuration changes to the startup
configuration. This ensures that the new configuration is present after a switch reboot. The Active=Saved
option can be enable on any FICON VSAN.
