2. Create the FCIP tunnel using the portcfg fciptunnel command. Note that the following example
creates an empty tunnel with hardware compression enabled to which you will add circuits.
Note that FCIP tunnels are represented in the switch as VE_Ports. There are several ways to
create this tunnel as shown by the following options:
To create the tunnel with hardware compression, use the following commands.
Site A
portcfg fciptunnel 16 create -c 1
Site B
portcfg fciptunnel 16 create -c 1
To use this tunnel for FICON traffic with hardware compression, create it with the following
commands.
Site A
portcfg fciptunnel 16 create --ficon -c 1
Site B
portcfg fciptunnel 16 create --ficon -c 1
To use this tunnel for FCP with Fastwrite and Open Systems Tape Pipelining traffic, and
hardware compression, create it using the following commands.
Site A
portcfg fciptunnel 16 create --fastwrite --tape-pipelining -c 1
Site B
portcfg fciptunnel 16 create --fastwrite --tape-pipelining -c 1
NOTE
To use software compression (only mode 2 would be valid for a 6 Gb Tunnel), specify “-c 2"
instead of “-c 1" in the preceding commands.
At this time, the tunnel has been created with the compression mode, and operational mode
defined. The tunnel is not usable yet. You must add circuits to the tunnel. The next step is to
create the circuits.
