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, read
“FICON emulation overview” on page 37.
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.
4. Verify the switches have been set up according to the instructions in “Configuring switched
point-to-point FICON” on page 16 and “Configuring Cascaded FICON” on page 20.
5. Configure the FCIP tunnel according to the Fibre Channel over IP Administrator’s Guide.
6. Enable compression on the FCIP tunnel.
7. Configure FICON emulation on the tunnel that is solution-specific.
