Fibre Channel Switch setup
====================
 I. FC Switch configuration  (Ex: Brocade )                                                                                                                               
  1. Open up a HyperTerminal
  2. Login as admin
  3. Enter password for password
  4. Type in configure
    1. Configure entire switch
  5. Type in Help
    1. List commands possible
  6. Type ipAddrSet
  7. Enter the Ethernet IP address
    1. Get from Tom York
  8. Enter the common SubNet Mask
    1. 255.255.252.0
  9. Hit enter twice after SubNet Mask
    1. Use default values
  10. Enter the gateway number, which is the same throughout the lab
    1. 147.145.175.254
  11. When ask to set respond by entering <y>
  12. Now type ipAddrShow
    1. Make sure the ip address held
  13. Now reboot
    1. This will take several minutes

 

II. Enable the Switches

  1. Connect to the internet
  2. Enter the address http:// ip address of the switch
  3. Now click on zone admin
  4. Enter admin for user name
  5. And enter password for password
  6. For zone selection select switch/port level zoning
  7. And click <ok>
  8. Click port zone tab
  9. Click create zone
  10. Name zone
  11. Go to switch port, domain and select ports 0 through 7
  12. Click add mem =>
  13. Create another zone
  14. Select ports 8 through 15
  15. Now select port config tab
  16. Highlight both new zone add them
    1. Under file zones
  17. Add mem =>
  18. Click enable config and then apply and okay
    1. All located on bottom of screen

                                                                                                                   
Switch Initialization:
·         At the Power ON, boot PROM diagnostics :
Ø       Verify CPU DRAM Memory.
Ø       Initialize base Fabric Operating System (FOS).
·         The Initialized FOS does the following:
Ø       Execute Power-On Self Test (POST) on switch.
Ø       Initialize ASICs & Front panel.
Ø       Initialize link for all ports (put online).
Ø       Explore the Fabric and determine the Principal Switch.
Ø       Assign Addresses to Ports.
Ø       Build Unicast routing table.
Ø       Enable N-Port operations.

Fabric Port Initialization Process: (From Switch Prospective)

Transition 1: At the beginning, verify if anything is plugged to Switch Port.
Transition 2: At FL-Port, Is there any Loop connections present in the Switch.
Transition 3: At G-Port, Verifying if any other (switch or Hubs) devices connected.
Transition 4: After G-Port, Verifying if Switch or Point-to-Point devices connected.

Communication Protocols:
  • Fabric Devices typically
Ø       FLOGI à PLOGI to Name Server à SCR to Fabric Controller à Register & Query [using FC Common Transport (FC_CT) Protocol] à LOGON.
  • Loop Devices typically
Ø       PRIVATE NL: LIP (PLOGI & PRLI will enable private storage devices that accept PRLI & thus “appear” Fabric capable)
Ø       PUBLIC NL: LIP à FLOGI à PLOGI à SCR à Register & Query à LOGO & then PLOGI à & Communicate with other end nodes in the fabric.
Ø       LIP Process include: LIP, LISM, LIFA, LIPA, LIHA, LISA and LIRP & LILP.

  1. Nice information. can you write a blog about what happens when we connect two fabrics ? This question was asked in Cisco Interview.. and what we call that term connecting two fabrics ?
