The Fabric ID is a number assigned to each switch chassis that identifies which
fabric it is connected with. Each switch in a fabric must have the same Fabric ID
number.
Press the Apply button to apply the Fabric ID to the chassis.
Chassis ID Field
The Chassis number represents bits 19 through 14 of the 24-bit Fibre Channel
Address.
The Chassis number is in the range of 00-63 and identifies a particular chassis
within the IO/T chassis group or a particular chassis within the CC chassis group
in a multi-chassis Switch fabric. IO/T and CC chassis are both numbered begin-
ning with 00. Switches come from the factory with a Chassis ID of zero and must
be assigned a unique value for the fabric in which it will be connected.
Press the Apply button to apply the Chassis ID number to the chassis.
Stage Type
Cascade and Mesh Fabrics
In a cascade or mesh fabric, switch chassis are connected together forming a
larger fabric. In these fabrics, all chassis are IO/T chassis. Some ports are
used as Input-Output fabric ports that connect to users, and some ports are
used as T_ports that interconnect the chassis.
Multi-Chassis Fabrics
In a multi-chassis Switch fabric there are three types of chassis, IO/T, CC,
and segmented loop. IO/T and CC stage types can be combined within a
fabric. Private loops dedicate all fabric Switch chassis to exclusive communi-
cation between private initiators and targets on the same loop and do not
allow any attached switches to function as an IO/T or CC.
NOTE:
It is illegal to have a Chassis ID number of zero in a fabric with an ID of zero. It is
best that Fabric IDs start at one.
NOTE:
If a Chassis ID of a switch has the same value as another switch in the fabric, only
one of the two switches will appear on the Topology window and the Logged-in
LED on the connection port(s) between the switches will blink rapidly.
