Enabling Stacking - Supermicro SSE-G48-TG4 Reference Manual

Super Micro Intelligent Switch Command Line Interface User Guide
It is acceptable to use a 1M stacking cable for port 1 and a 12M uplink cable for port 2.
You will only need to configure the long cable preference for port 2. The way to configure
this is:
SMIS# config term
SMIS(config)# int ex 0/2
SMIS(config-if)# cx4-cable-length long
This configuration is done on an individual port basis. Thus, you can use "short" for one
port and "long" for the other port. Alternatively you might use both "short" or, if neither
port is used for stacking, both can be "long" cables.

Enabling Stacking

Super Micro switches by default act as stand alone switches. This standalone default
facilitates using 10G Ethernet ports as Extreme Ethernet ports for uplinks.
When stacking is enabled the stacking ports are dedicated for stacking purpose.
Stacking can be enabled by using the command "stack" with a switch identifier and a
priority. The detailed command syntax is explained below:
When stacking is enabled, the switch needs to be rebooted to take it effective.
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.
In the stacking mode, any firmware upgrade in the Master Switch will
automatically initiate a firmware upgrade to all attached stack member switches.
Firmware upgrade confirmation from stack member switches will be displayed in
the Master Switch management interface.
In the stacking mode, the user can reload all stacked switches or any selected
stack member switch from the master management interface.
The interface numbers change between stacking and non stacking cases due to the switch
id. Hence configurations saved for stacking are not valid for non stacking cases and vice
versa.
If the user chooses stacking using the "stack" command while the switch is in a
non-stacking state and if the configurations are already saved for restoring; the
switch will rename the configuration file by adding a suffix _nonstack and will
not restore this file when the switch reboots with stacking enabled.
Similarly if the user chooses non-stacking using the "no stack" command while
the switch is in a stacking state and if the configurations are already saved for
