Enhanced Stacking Guidelines
Here are the guidelines to using the enhanced stacking feature:
There can be up to 24 switches in an enhanced stack.
The switches in an enhanced stack must be connected with 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
connected using tagged or untagged ports of the VLAN.
A slave switch can be connected indirectly to the master switch
through other switches so long as there is an uninterrupted path of the
common VLAN from the master switch to the slave switch.
You must add a routing interface to the common VLAN on the master
switch and designate it as the master switch’s local interface.
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, a routing interface
is required if you use any other VLAN as the common VLAN. However,
you do not have to designate it as the local interface.
You can create different stacks by connecting different groups of
switches with different common VLANs and subnets.
An enhanced stack must have at least one master switch. You
designate the master by changing its stacking status to Master.
An enhanced stack can consist of other Allied Telesis switches that
support this feature, including the AT-8000, AT-8400, AT-8500, and
AT-9400 Switches. For more information, refer to “Enhanced Stacking
Compatibility” on page 66.
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.
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.
