spantree vlan

spantree vlan
Enables or disables the Spanning Tree status on a port or a link aggregate of ports for the specified VLAN
instance.
spantree vlan vlan_id [-vlan2] {port slot/port[-port2] | linkagg linkagg_id[-linkagg_id2]} {enable |
disable}
Syntax Definitions
vlan_id
slot/port[-port2]
linkagg_id[-linkagg_id2]
enable
disable
Defaults
By default, the Spanning Tree status is enabled on eligible ports.
Platforms Supported

Usage Guidelines
•
This command only applies to the specified VLAN instance regardless of which Spanning Tree operat-
ing mode (flat or per-VLAN) is active for the switch.
•
If the switch is running in the flat mode when this command is used, the Spanning Tree status
configured for the port is not active for the specified VLAN instance until the operating mode for the
switch is changed to the per-VLAN mode.
•
When the Spanning Tree status is disabled on a port, the port is set to a forwarding state for the
specified instance.
•
If STP is disabled on a VLAN in the per-VLAN mode, the port Spanning Tree status is ignored and all
active ports associated with the VLAN are put in a forwarding state and not included in the Spanning
Tree Algorithm. Note that when this occurs, ports will not bridge BPDU unless the BPDU switching
status for the VLAN is enabled.
•
Physical ports that are reserved for link aggregation do not participate in the Spanning Tree Algorithm.
Instead, the algorithm is applied to the aggregate logical link (virtual port) that represents a collection
of physical ports.

-> spantree vlan 2 port 4/1 enable
