You can determine if fmsmode is enabled by using the ficoncupshow fmsmode command.

Configuring VEX_Ports

If you are going to use a VEX_Port in your tunnel configuration, use the portCfgVEXPort command to
configure the port as a VEX_Port. VEX_Ports can be used to avoid merging fabrics over distance in
FCIP implementations.
If the fabric is already connected, disable the GbE ports and do not enable them until after you
have configured the VEX_Port. This prevents unintentional merging of the two fabrics.
VEX_Ports are described in detail in the "Using the FC-FC Routing Service" chapter of the Fabric OS
Administrator's Guide. Refer to that publication if you intend to implement a VEX_Port.
The following example configures a VEX_Port, enables admin, and specifies fabric ID 2 and
preferred domain ID 220:

Enabling XISL for VE_Ports

An Extended Interswitch Link (XISL) is a special ISL that can carry combined traffic for multiple
logical fabrics while maintaining traffic separation for each fabric. An XISL connection is created
between user-defined logical switches, called base switches, instead of using separate ISLs
between logical switches. The base fabric provides the physical connectivity across which logical
connectivity will be established. Because of the expense of long-distance links, this feature has
particular benefit for the FCIP extension platforms. This feature is supported only on tunnels
between FX8-24 blades running Fabric OS v7.0 and later. The blades can be operating in both 1
Gbps and 10 Gbps modes.
NOTE
Although you can create up to four logical switches on the Brocade 7800, you cannot use these for
XISLs because a base switch cannot be created.
To use XISL, add the Enable XISL Use parameter to the configure command for the logical switch
where you intend to use XISL with VE_Ports. Refer to the Fabric OS Command Reference Manual
for details.

Configuring the media type for GbE ports 0 and 1 (7800 switch only)

Two media types are supported for GbE ports 0 and 1 on the 7800 switch; copper and optical. The
media type must be set for GbE ports 0 and 1 using the portcfggemediatype command. The
following example configures port 1 (ge1) in optical mode.
switch:admin> portcfggemediatype ge1 optical
The command options are as follows:
ge0|ge1
copper|optical
When you enter this command without specifying the media type, the current media type for the
specified GbE port is displayed, as in the following example.
