Distributed Spanning Tree Commands spantree cist connection
OmniSwitch CLI Reference Guide March 2011 page 5-51
spantree cist connection
Configures the connection type for a port or a link aggregate of ports for the flat mode Common and Inter-
nal Spanning Tree (CIST).
spantree cist {port slot/port [-port2] | linkagg linkagg_id [-linkagg_id2]} connection {noptp | ptp |
autoptp}
Syntax Definitions
slot/port[-port2] The slot number and port number of the physical port. Use a hyphen to
specify a range of ports (4/1-8)
.
linkagg_id[-linkagg_id2] The link aggregate ID number. Use a hyphen to specify a range of IDs
(10-20).
noptp Defines port connection type as no point to point link.
ptp Defines port connection type as point to point link.
autoptp Specifies that switch software automatically defines connection type as
point-to-point or no point-to-point.
Defaults
By default, the link connection type is set to auto point-to-point.
Platforms Supported
OmniSwitch 10K
Usage Guidelines
•
This command only applies to the port connection type for the CIST instance regardless of which oper-
ating mode (flat or per-VLAN) is active for the switch.
•
If the switch is running in per-VLAN 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.
•
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 must 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.
