Stacking Information and Topologies

The E3800 switches support the HP FlexChassis Mesh feature for stacking
the switches. When E3800 Stacking Modules (J9577A) are installed in the
switches, any combination of up to ten E3800 switches can be stacked
together via high-speed backplane cables to form a single extended virtual
switch. The stacking topologies supported depend on the number of switches
being stacked.
The stacking cables and connections operate independently of any layer 2 or
layer 3 network protocols and features, including Spanning Tree. When
multiple switches are stacked, they behave as a single, virtual switch with
additional network ports being supplied by the stack members.
If an E3800 switch is powered on for the first time without a stacking module
installed, stacking will be disabled and that will be saved in the switch's
running configuration. Subsequently, after a stacking module has been
installed, stacking must be enabled through the console (CLI) command
stacking enable.
To set up a stack of E3800 switches, you should:
1. Power off all switches that are going to be stacked.
2. Install Stacking Modules in the switches, and connect the stacking cables
to create your stacking topology.
3. Power-on each switch, one at a time. The first switch that you should
power on is the one that you want to be the Commander of the stack. The
second one will become the stack Standby. For the other stack members,
their Member ID is determined by the sequence in which they are booted.
There are additional methods for creating your E3800 stack. For configuration
options and other information on stacking, see "Stack Management" chapter
in the E3800 Advanced Traffic Management Guide.
