Operating Rules For Stacking - HP ProCurve Series 4100GL Management And Configuration Manual

Operating Rules for Stacking

General Rules
■ Stacking is an optional feature (enabled in the default configuration)
and can easily be disabled. Stacking has no effect on the normal
operation of the switch in your network.
■ A stack requires one Commander switch. (Only one Commander
allowed per stack.)
All switches in a particular stack must be in the same IP subnet
■
(broadcast domain). A stack cannot cross a router.
A stack accepts up to 16 switches (numbered 0-15), including the
■
Commander (always numbered 0).
■ There is no limit on the number of stacks in the same IP subnet
(broadcast domain), however a switch can belong to only one stack.
■ If multiple VLANs are configured, stacking uses only the primary
VLAN on any switch. In the factory-default configuration, the
DEFAULT_VLAN is the primary VLAN. (See "Stacking Operation with
Multiple VLANs Configured" on page 15-44 and "The Primary VLAN"
on page 12-6.)
■ Stacking allows intermediate devices that do not support stacking.
This enables you to include switches that are distant from the
Commander.
