Allowing the Host to Change FICON Port Parameters

By default, mainframe users are not allowed to configure FICON parameters on Cisco MDS
switches—they can only query the switch.
To allow the host (mainframe) to configure FICON parameters on the Cisco MDS switch 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
Check the Port Control By Host check box to allow the mainframe to control a switch.
Step 3
Click the Apply Changes icon to save the changes.
Step 4

Allowing the Host to Control the Timestamp

By default, the clock in each VSAN is the same as the switch hardware clock. Each VSAN in a Cisco
MDS 9000 Family switch represents a virtual director. The clock and time present in each virtual director
can be different.To maintain separate clocks for each VSAN, the Cisco NX-OS software maintains the
difference of the VSAN-specific clock and the hardware-based director clock. When a host (mainframe)
sets the time, the Cisco NX-OS software updates this difference between the clocks. When a host reads
the clock, it computes the difference between the VSAN-clock and the current director hardware clock
and presents a value to the mainframe.
To configure host (mainframe) control for the VSAN time stamp using Fabric Manager, follow these
steps:
Step 1 Choose VSAN > FICON.
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
Check the Host Can Sync Time checkbox to allow the mainframe to set the system time on the switch.
Step 3
Click the Apply Changes icon to save these changes.
Step 4

Configuring SNMP Control of FICON Parameters

By default, SNMP users can configure FICON parameters through the Cisco MDS 9000 Family Fabric
Manager.
