Telnet Commands
Core Switch PID Format
This is used to set the 256 port PID format that is used for core
switches.
Per-frame Route Priority
In addition to the eight virtual channels used in frame routing
priority, support is also available for per-frame based prioritization
when this value is set. When this mode is set to 1, the virtual channel
ID is used in conjunction with a frame header to form the final virtual
channel ID.
Long Distance Fabric
When this mode is set to 1, ISLs in a fabric can be up to 100 km long.
The exact distance level 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 will be
segmented. The Extended Fabric License is required to set this mode.
Virtual Channel
Settings
The switch enables fine tuning for a specific application, by
configuring the parameters for eight virtual channels. The first two
virtual channels are reserved for switch internal functions and are not
available for modification.
The default virtual channel settings have already been optimized for
switch performance.
CAUTION
!
Changing the default values can degrade performance. Do not
change these settings without fully understanding the effects of the
changes.
