EtherChannel Management Window
Per VLAN STP Setting
Note
Per VLAN STP configuration is disabled in the Cat OS or Hybrid environments.
The Per VLAN STP Setting area provides the following information:
•
VLAN—Describes the STP per-VLAN configurations of a trunking interface. There is one entry for
each explicit per-VLAN spanning tree configuration on the interface.
Note
The VLAN STP instance does not have to be currently carried on the trunk in order to configure
the per-VLAN STP settings. The settings will take effect when the interface actually begins
trunking the VLAN traffic.
•
Priority—Describes the STP VLAN port priority of this interface. The VLAN port priority is used
on trunking interfaces. On any switch port that is not in trunking mode, the STP port priority is used
instead. The default value is 128 in all versions of IOS, 32 in all versions of CatOS. The valid values
are:
–
Native IOS 12.1(6)E and earlier:Integer (0..248) [increments of 8]
–
Native IOS 12.1(8a)E and later:Integer (0..252) [increments of 4]
–
CatOS 6.3:Integer(0..63)
–
CatOS 7.1:Integer(1..63)
•
Cost—Describes the STP VLAN path cost of this interface. The VLAN path cost is only used on
trunking interfaces. On any switch port that is not in trunking mode, the STP port path cost is used
instead.
Note
Default values for priority and cost will be used if you do not provide one of these arguments.
You must provide a nondefault value for at least one of these arguments, otherwise the action
will fail.
•
Add/Remove Per VLAN STP Setting—Launches the EtherChannel Management—Add/Remove
per VLAN Settings window to add and remove an explicit STP VLAN configuration to the interface.
The configuration will only have an effect if the interface is in trunking mode and the VLAN has an
associated STP instance. The interface does not currently need to be configured as a trunking port,
nor does the VLAN or the VLAN STP instance need to exist.
