 802.3x Flow Control
 Independent VLAN Learning Support
 TCP/IP Networking Stack
 Multi-Unit Stacking (multiple blades in a system are managed from the
same user interface)

6.4.2 Installation
6.4.2.1 Stacking Architecture
The idea of stacking is to allow the user the ability to
manage the multiple GSWU cards in one system as one
switch, instead of individual units and IP addresses, etc. For
example, a set of three blades would appear to the UI as a
24 port switch instead of three 8-port switches. The stacking
will work by assigning a Master Management Card which
provides all the GUI information for all the blades in the
same stack. The CCPU assigns the Master by issuing an IP
address via PAW/PRW. All other GSWU cards detected in
the system are not assigned an IP address signifying them
as Slave blades.
A single system can have up to 12 GSWU cards per system.
However, only three GSWU units can be grouped together
forming a single 20 port switch. When more than three
GSWU units are present within a system, the additional
units will not have any of the software features specified in
this document. They will behave as an unmanaged Gigabit
Ethernet switch, as defined later in this document.
The three GSWU boards can be categorized into one Main
board, with two additional Add-on boards.
