Enhanced
Stacking
Guidelines
Here are the guidelines to using the enhanced stacking feature:
ˆ There can be up to 24 switches in an enhanced stack.
ˆ The switches in an enhanced stack must be interconnected by a
common port-based or tagged VLAN. The VLAN must have the same
name and VLAN identifier (VID) on each switch, and the switches must
be interconnected using tagged or untagged ports of the VLAN.
ˆ A slave switch can be connected indirectly to the master switch so long
as there is an uninterrupted path of the common VLAN from the master
switch to the slave switch.
ˆ You must add a routing interface to the common VLAN on the master
switch and designate the interface as the master switch’s local
interface.
ˆ You do not need to create a routing interface in the common VLAN on
the slave switches if you use the Default_VLAN (VID 1) as the
common VLAN of the switches of a stack. However, if you use any
other VLAN as the common VLAN, you must add a routing interface to
it on the slave switches, but you do not have to designate it as the local
interface.
ˆ You can create different stacks by interconnecting different groups of
switches with different common VLANs and subnets.
ˆ An enhanced stack must have at least one master switch. You
designate the master by changing its stacking status to Master.
ˆ An enhanced stack can consist of other Allied Telesyn switches that
support this feature, including the AT-8000 Series, AT-8400 Series,
AT-8500 Series, and AT-9400 Series switches. For more information,
refer to “Enhanced Stacking Compatibility” on page 92.
ˆ In order to manage the stack remotely using a Telnet or SSH client or a
web browser, the remote management workstation must reach the
master switch through the subnet of the switch’s local interface.
ˆ The IP address 172.16.16.16 is reserved for the enhanced stacking
feature and must not be assigned to any device on your network.
