HP ProCurve Stack Management
Configuring Stack Management
N o t e
In the default stack configuration, the Candidate Auto Join parameter is
enabled, but the Commander
Auto Grab
parameter is disabled. This prevents
Candidates from automatically joining a stack prematurely or joining the
wrong stack (if more than one stack Commander is configured in a subnet or
broadcast domain). If you plan to install more than one stack in a subnet, HP
recommends that you leave
Auto Grab
disabled on all Commander switches
and manually add Members to their stacks. Similarly, if you plan to install a
stack in a subnet (broadcast domain) where stacking-capable switches are
not intended for stack membership, you should set the
Stack State
parameter
(in the Stack Configuration screen) to Disabled on those particular switches.
Configuring Stack Management
Overview of Configuring and Bringing Up a Stack
This process assumes that:
■ All switches you want to include in a stack are connected to the same
subnet (broadcast domain).
■
If VLANs are enabled on the switches you want to include in the stack,
then the ports linking the stacked switches must be on the primary
VLAN in each switch (which, in the default configuration, is the
default VLAN). If the primary VLAN is tagged, then each switch in the
stack must use the same VLAN ID (VID) for the primary VLAN. (Refer
to “The Primary VLAN” on page 12-6, and “Stacking Operation with
Multiple VLANs Configured” on page 15-44.)
■
If you are including an HP ProCurve Switch 8000M, 4000M, 2424M,
2400M, or 1600M in a stack, you must first update all such devices
to software version C.08.03 or later
. (You can get a copy of the latest
software version from HP’s ProCurve website and/or copy it from one
switch to another. For downloading instructions, see appendix A,
"File Transfers", in the
Management and Configuration Guide for
these switch models.)
