DXS-3350SR Gigabit Layer 3 Switch
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:
Token Cost * Number of Switches ≤ 32
Model Name Token Cost
DGS-3324SRi 2
DGS-3324SR 2
DES-3352SR 2
4 DXS-3350SR
6 (with 10G uplink)
2 DXS-3326GSR
4 (with 10G uplink)
