Stack - Supermicro SSE-X3348T/R User Manual

Stack

The Supermicro Intelligent switch supports stacking of the SSE-G24-TG4 and
SSE-G48-TG4 Supermicro switch units. Switch stacking is created by connecting
switches in a daisy chain. One of the stacked switches is selected as a Master based on
its configurations. The Master switch provides management support for the whole stack.
Other switches in the stack are referred to as slave switches.
NOTE: Make sure all stacked switches are running the same version of
firmware.
The Master switch manages the control plane traffic for all stacked switches. When the
current master switch fails, the backup master is then selected as the current master.
The Master selection algorithm is based on a priority configuration. If two switches have
the same priority, the switch with the lowest MAC address is selected as the Master
switch.
Enabling Stacking
By default, Supermicro switches act as stand-alone switches. This stand-alone default
facilitates using 10G Ethernet ports as Extrement Ethernet ports for uplinks.
When stacking is enabled the stacking ports are dedicated for stacking purposes.
Stacking can be enabled using the command stack with the switch identifier and
priority. The detailed command syntax is explained below.
NOTE: When stacking is enabled, the switch needs to be rebooted to make it
effective.
NOTE: When a switch is acting as a stand-alone switch with stacking disabled,
all physical interfaces are numbered as 0/1 to 0/n.
When the switch is in stacking mode, the interfaces are numbered as <switch
id>/1 to <switch id> / n.
In non-stacking mode, the switch ID is considered to be 0.
The interface numbers change between stacking and non-stacking cases due to the
switch ID. So configurations saved for stacking are not valid for non-stacking cases and
vice versa.
