When you convert a device from one of the Stacking modes to Standalone mode,
the stack ports automatically become network ports.
Port Speeds
The speed of stack ports can be set manually or set to auto selection. The
following describes the available types of stack ports and their speeds on the
various types of devices:
Auto Selection of Port Speed
You can set the stacking cable type to be discovered automatically when the
cable is connected to the port (auto-discovery is the default setting). The system
automatically identifies the stack cable type and selects the highest speed
supported by the cable and the port.
A SYSLOG message (informational level) requesting that the user configures the
port speed manually is displayed when the cable type is not recognized.
Connecting Units
Two units can only be connected in a stack if the ports on both ends of the link are
of the same speed. This is done by configuring the stack ports speed to:
• Auto Speed mode
• Same speed on each side of the connection
