Note the following port mapping rules on the Brocade FX8-24: The Brocade
FX8-24 has two FCIP chips and each one controls specific GbE ports and VE
ports. The first FCIP chip controls VE_Ports 12-21, and the GbE ports ge0-ge9
and the local XGE port, xge1. The second FCIP chip controls VE_Ports 22-31 and
the local XGE port, xge0. Typically (that is in the case when you do not configure a
failover crossport) you use the IP addresses on ge0-ge9 and xge1 for any FCIP
circuits that use VE_Ports 12-21. And likewise, you use IP addresses on xge0 for
any FCIP circuits that use VE_Ports 22-31. When you configure a failover
crossport, the VE_Ports on one chip are allowed to use the IP addresses on the
non-local chip's XGE port (crossport).
The valid VE ports on the Brocade 7840 switch are VE_Ports 24-43. In 10VE
mode, only VE_Ports 24-28 and VE_Ports 34-38 are supported. In 20VE mode all
VE ports are supported.
The syntax for portcfg fciptunnel is as follows:
portcfg fciptunnel [slot/]ve_port options [tunnel_arguments] [circuit_arguments]
The following options are supported with fciptunnel:
create [tunnel_arguments][circuit_arguments]
Creates an FCIP tunnel and, optionally a single default circuit. If no circuit
arguments are specified, no FCIP circuit will be created. While it is possible to
create a tunnel without a default circuit, it is an unlikely scenario (for example, for
configuration staging purposes). In most cases, you will create a tunnel with at
least one configured FCIP circuit. In this case, you must specify a remote and
local IP address for the circuit as well as a committed rate (or alternately, a
minimum and maximum committed rate) to configure the default circuit. The
default circuit created with the tunnel is automatically assigned the circuit ID 0.
You can modify the default circuit with the fciptunnel modify command. To add
additional circuits to an existing tunnel, use the fcipcircuit create command.
modify [tunnel_arguments][circuit_arguments]
Modifies the properties of an existing FCIP tunnel. To modify a tunnel, you must
specify at least one of the tunnel or circuit parameters for the command to be
effective. Any circuit attribute you change with the fciptunnel modify command
affects only the FCIP circuit 0. All other circuits remain unchanged. To modify a
circuit other than circuit 0, you must use the fcipcircuit modify command.
In order to create a default circuit 0 with the tunnel, you must at least specify the
following circuit arguments with fciptunnel create:
-D | --remote-ip-address remote_ip_address
Specifies the IP address for the remote end of the FCIP circuit.
-S | --local-ip-address local_ip_address
Specifies the IP address for the local end of the FCIP circuit.
The following two operands are exclusive; you can either specify a committed
rate or a minimum and maximum rate for circuit 0. You can modify these
parameters later with fciptunnel modify.
-b | --min-comm-rate value -B | --max-comm-rate value
Alternately you may set a minimum and a maximum for the committed rate to
configure the tunnel for Adaptive Rate Limiting (ARL), which allows for a
more effective sharing of bandwidth between applications. The valid range is
10,000 Kbps to 1,000,000 Kbps for 1G ports and 10,000 Kbps to 10,000,000
Kbps for 10G ports. The maximum committed rate is the combined maximum
committed rate of all configured circuits and it can be no larger than five times
the minimum committed rate. Both sides of the circuit must have matching
configurations.
