Note:
mode cannot be enabled.
Disable Translative Mode
The setting is relevant only if VC encoded address mode is also set. This feature, when set,
disables translative addressing to achieve explicit address compatibility with some
first-generation switches. Set this feature only if hardware or software systems are attached to
the fabric that explicitly rely on a specific frame address format.
Switch PID Format
The setting is relevant only if VC encoded address mode is not set:
If VC encoded address mode is not set, the default setting is 1.
Note:
Per-Frame Route Priority
In addition to the eight virtual channels used in frame routing priority, support also is available
for per-frame-based prioritization when this value it set. When set, the virtual channel ID is
used with a frame header to form the final virtual channel ID.
Long-Distance Fabric
When this mode is set, ISLs in a fabric can be up to 100 km. The exact distance is determined
by the per-port configuration on the E_Ports of each ISL. Both E_Ports in an ISL must be
configured to run the same long-distance level; otherwise, the fabric segments.
The Extended Fabrics license is required to set this mode.
Virtual Channel Settings
The switch provides the ability to tune the switch in a specific application by configuring the
parameters for the switch's eight virtual channels. The first two virtual channels are reserved
for the switch's internal functions and are not user configurable.
Fabric OS 3.x Document Addendum
VC encoded address mode cannot be set in security mode. When this mode is set, security
0 Native PID format (16 based, 16 port format), for fabrics with legacy low-count-port
switches
1 Core PID format (0 based, 256 port format), preferred mode for mixed fabrics with
legacy and new switches
2 Extended-edge PID format (16 based, 256 port format), used in mixed fabrics with
legacy and new switches to avoid rebooting host systems when static PID binded is used
The configdefault command does not change switch PID format.
