7.6.11.4 VLAN
Configures the Bridge VLAN ID used in PVST+ (Per VLAN Spanning Tree) environment. All ports assigned to this
bridge instance must be members of the VLAN used. The VLAN is in the 1..4094 range. VLAN 1 is used to build a
spanning tree common to all VLANs. Unlike what happens with other manufacturers, here you need to explicitly cre-
ate the instance associated to VLAN 1. Please see the chapter on Examples for a configuration example.
Syntax:
ethernet0/0 switch config>stp <instance> vlan <vlan-id>
Note
If you do not assign a VLAN identifier to the Spanning Tree instance, make sure all ports assigned to
this Spanning Tree instance are not assigned to other Spanning Tree instances. To configure PVST+,
ensure you create an instance associated to VLAN 1.
Example 1:
Configuration for PVST+ instances associated to VLANs 21, 22 and 30. Port 4 uses VLAN 30 as native VLAN.
ethernet0/0 switch config>port 1 stp enable instance 2
ethernet0/0 switch config>port 1 stp enable instance 3
ethernet0/0 switch config>port 2 stp enable instance 2
ethernet0/0 switch config>port 2 stp enable instance 4
ethernet0/0 switch config>port 3 stp enable instance 3
ethernet0/0 switch config>port 4 stp enable instance 4
ethernet0/0 switch config>stp 2 vlan 21

Example 2:
Configuration for a common instance associated to VLAN 1.
ethernet0/0 switch config>port 3 stp enable instance 1
ethernet0/0 switch config>port 4 stp enable instance 1
ethernet0/0 switch config>stp 1 vlan 1
ethernet0/0 switch config>exit
ethernet0/0 config>exit
7.6.11.5 BRIDGE-PRIORITY
Configures the priority assigned to the bridge used to form, together with the bridge MAC address, the bridge identifi-
er. The value must be between 0 and 65535. The 12 least significant bits for the priority must be 0. If they aren't, the
device rounds them up to the nearest valid priority. Default priority for a port is 32768.
Example:
ethernet0/0 switch config>stp 2 bridge-priority 32120
value rounded to 28672
