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).
■ The stacking feature supports up to 100 switches in the same IP
subnet (broadcast domain). A switch can belong to only one stack. In
the event that the 100 switch limit is exceeded, it may take multiple
attempts to add or move a member to any given stack. Once a member
is added to a stack, it is not "forgotten" by the Commander.
■ Viewing Stack Status (all) only displays up to 100 devices. Devices
that are not members of a given stack may periodically "drop out" of
the list when viewing Stack Status (all).
■ 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 7-46 and "The Primary VLAN"
on page 2-6.)
■ Stacking allows intermediate devices that do not support stacking.
This enables you to include switches that are distant from the
Commander.
