Configuration steps
2
The following example configures a VEX_Port, enables admin, and specifies fabric ID 2 and
preferred domain ID 220:
switch:admin> portcfgvexport 18 -a 1 -f 2 -d 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.
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 geO for port 0 or ge1 for port 1.
copper|optical The media type.
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.
switch:admin> portcfggemediatype ge1
Port ge1 is configured in optical mode
Setting the GbE port operating mode (FX8-24 blade only)
The GbE ports on an FX8-24 blade can operate in one of three ways:
• 1 Gbps mode. GbE ports 0 through 9 may be enabled as GbE ports, with the XGE ports
disabled. The 10GbE (FTR_10G) license is not required.
• 10 Gbps mode. 10GbE ports xge0 and xge1 may be enabled, with GbE ports 0 through 9
disabled. The 10GbE (FTR_10G) license is required and must be assigned to the slot in
which the FX8-24 blade resides.
• Dual mode. GbE ports 0 through 9 and 10GbE port xge0 may be enabled, with xge1 disabled.
The 10GbE (FTR_10G) license is required and must be assigned to the slot in which the
FX8-24 blade resides.
NOTE
Switching between 10Gbps mode and 1Gbps mode disrupts FCIP traffic.
