You are working with a customer to configure FICON on a Cisco MDS switch. In order to make sure that the customer can modify the FICON port parameters for the MDS switch from the mainframe, which of these must occur?
It is not possible to alter the MDS FICON port parameter from the mainframe. Mainframe users can only view and monitor the MDS FICON port parameters. Changes are made via Cisco Fabric Manager, Cisco Device Manager, or the command-line interface.

12 credits will be set.
What method of load balancing is flow based?
Set all ports in a 48-port line card to 1 GB dedicated, with all remaining options set to the defaults. You have two available 1-GB switchport mode dedicated ports on a 48-port line card.

no FC-SP authentication protocol exchange will be performed (no AUTH messages sent)
You are asked to design a full-mesh core solution using the following equipment: 3 x 9509, fully loaded with 32 port FC modules (D8-X9032) 3 x 9506, fully loaded with 32 port FC modules (D8-X9032) The solution requires 4 Gb/s of bandwidth for the ISLs between switches. What is the number of available physical ports for fibre channel host and storage connectivity within the physical fabric?
FICON (for Fiber Connectivity) is a high-speed input/output (I/O) interface for mainframe computer connections to storage devices. You have two Cisco MDS 9509 switches for a FICON connection. FCIP is used between the two switches. On each switch is one 24-port module, two 32-port modules, and one 48-port module. What is the first available FICON port number for the FCIP connection on the switches?
What TCP feature reduces the chances of an oversized IP packets from being fragmented?
There are three different roles on MDS: Role1 allows show commands only. Role2 allows debug and configure commands, and denies show command Role 3 permits VSAN 10-30 only. User1 belongs to Role1, Role2 and Role3. What can User1 do?
Show, debug, configure on all VSAN
Read only zones on MDS switches are implemented using:
SCSI I/O operation type
What SCSI command does a target send to an initiator after the initiator sends the target a write command?
What control traffic is NOT prohibited from crossing Inter-VSAN boundaries?
RSCN and SW-RSCN for devices within the affected IVR zone(s)/active zoneset
What do ARB, R_RDY and IDLE have in common?
They are Primitive Signals as defined in FC-PH & FC-AL
