Configuring FICON emulation

Before you configure FICON emulation, you need to understand the available options, and whether

those options are to be implemented in your installation. If FICON emulation is new to you, refer to

“FICON emulation overview” on page 47.

ATTENTION

Make sure both ends of the tunnel match before bringing it up or the tunnel will not form.

1. Verify that the following ports are opened in the IP network for FCIP:

• TCP 3225—FC Class F frames

• TCP 3226—FC Class 2 and 3 frames

• TCP 3227—Brocade proprietary IP path performance utility (ipPerf)

• IP protocol 6—Transmission Control Protocol

• IP protocol 108—IP Payload Compression Protocol (IPComp)

NOTE

The 4 Gbps platform uses TCP port 3227 for ipPerf and IP protocol 108 for compression.

The 8 Gbps platform runs over the FCIP tunnel, not TCP/IP directly like ipPerf. No specific TCP

port is needed. Also the 8 Gbps platform compresses at layer 4 and no protocol is used.

2. Verify that the firmware is version v6.1.0e or later using the firmwareShow command.

3. Verify the correct licenses are installed using the licenseShow command. You can verify all

slot-based licenses in a chassis using the licenseslotcfg --show command.

4. Verify the switches have been set up according to the instructions in “Configuring switched

point-to-point FICON” on page 20 and “Configuring cascaded FICON” on page 25.

5. Configure the FCIP tunnel according to the FCIP Administrator’s Guide.

6. Enable compression on the FCIP tunnel.

7. Configure FICON emulation on the tunnel that is solution-specific. Refer to “Configuring

emulation on the 7800 switch and FX8-24 blade” on page 54.

8. If you have more than one tunnel being configured, take the following actions:

• If there is more then one tunnel to the same destination and their tunnel commit rates are

different, configure the link cost values the same.

• Configure TI Zones ensuring that if there are multiple E_Ports of different link costs, from

one switch to another switch within TI Zones, configure the link cost values to be the same.

Configuring emulation on the 7800 switch and FX8-24 blade

You can configure FICON emulation with such features as Teradata read, Teradata write, printer

emulation, tape write pipelining, tape read pipelining, TIN/TIR, device level ACK, and IBM z/OS

Global Mirror (formerly XRC) emulation enabled. Following are examples for enabling IBM z/OS

Global Mirror, Teradata emulation, tape read and write pipelining, and printer emulation.
