Configuring UFM-U Modes
Before changing the mode on a UFM-U, you must first determine whether the mode change will cause
any changes in the maximum port speeds of any active ports. If the maximum port speed on an active
port will change because of a mode change, you must first delete all connections in that port’s port group
and down all active ports in that port group before changing the mode.
For example, if you have connections on ports 1, 3, and 9 through 12 in mode 1 and you want to change
to mode 4, you must first delete all connections on ports 1 and 3, then down ports 1 and 3 before
changing to mode 4.
If you have connections on ports 1, 3, 5, 7, 9, and 11 in mode 2 and you want to change to mode 9, you
must first delete connections on ports 1 and 3, then down ports 1 and 3 before changing to mode 9. After
changing to mode, you must reestablish all of your connections on port 1 only.
Note If you do not have connections on a port in the port group but the port has been upped, you must still
down all ports in the port group before changing the mode.
See the “Changing the Mode on a UFM-U” section on page 2-56 for information on how to change
modes on the UFM-U.
Changing the Mode on a UFM-U
To change modes on a previously-configured UFM-U, use the following procedure:
Step 1 Delete all connections on port groups where the maximum port speeds will change because of the mode
change with the switch software delcon command.
Step 2 Deactivate all active ports in port groups where the maximum ports speeds will change with the switch
software dnport command.
Step 3 Using the switch software cnfport command, configure new port speeds for all appropriate ports in any
port group where maximum port speed changes will occur due to the mode change.
Step 4 Change the mode on the UFM-U with the switch software cnfmode command.
Step 5 Activate all necessary ports for the new mode with the switch software upport command.
Step 6 Add necessary connections to the UFM-U with the switch software addcon command.
