DXS-3326GSR Gigabit Layer 3 Switch
For stacking the in a ring architecture, both SIO ports will be in use, as shown in the following diagram. Up to 12
DXS-3326GSR switches may be stacked together in the ring architecture switch stack, though there are limitations on
stacking, which will be discussed in the following section.
Figure 3- 8. Stacking in a Ring Architecture
NOTICE:
Do not connect the stacked Switch group to the network until
you have properly configured all Switches for stacking. An improperly
configured Switch stack can cause a broadcast storm.
Stacking Limitations Utilizing a Ring or Star Toplogy
The Switches listed in the table below can all be stacked, but there is a limitation as to the number of Switches that can
be included in a given stack. This limitation arises from a concept called a Token Cost. This Token Cost is used for
communication between switches in a switch stack. Some of the switches have 2 as their token cost, while others are 4,
and the 10G uplink ports have a Token Cost of 2. The maximum accumulated Token Cost in a given stack must be less
than 32.
There is an additional limitation in that a maximum of 12 Switch boxes can be included in a given switch stack, using a
ring topology.
In order to make the task of determining if a given set of Switches (from the table below) can be successfully stacked,
use the following formula:
