Usage Guidelines
•
This command is an explicit Spanning Tree command that only applies to the port connection type for
the CIST instance regardless of which operating mode (flat or 1x1) is active on the switch.
•
If the switch is running in 1x1 mode when this command is used, the specified port connection type is
not active for the CIST instance until the operating mode for the switch is changed to the flat mode.
•
Note that when a configuration snapshot is taken of the switch, all Spanning Tree commands are saved
in their explicit format.
•
A port is considered connected to a point-to-point LAN segment if the port belongs to a link aggregate
of ports or if autonegotiation determines the port should run in full duplex mode or if full duplex mode
was administratively set. Otherwise, the port is considered connected to a no point-to-point LAN
segment.
•
Rapid transition of a designated port to forwarding can only occur if the port connection type is defined
as a point-to-point or an edge port. Rapid transition of an alternate port role to a root port role is not
affected by the port connection type definition.
OmniSwitch CLI Reference Guide
Enter the slot number for the module and the physical port number on
that module (for example, 3/1 specifies port 1 on slot 3).
Link aggregate ID number (0–31).
Defines port connection type as no point-to-point link.
Defines port connection type as point-to-point link.
Specifies that switch software automatically defines connection type as
point-to-point or no point-to-point.
