Pvst/Pvst+ Compatibility; Pvst/Pvst+ Compatibility - 07.6.04 And Later - HP ProCurve 9304M Installation And Configuration Manual

HP9300(config-vlan-3801)# spanning-tree priority 20
HP9300(config-vlan-3801)# tag ethernet 1/20 ethernet 5/1 to 5/3
HP9300(config-vlan-3801)# exit
The next group of commands configures VLAN groups for the member VLANs. Notice that the VLAN groups do
not contain the VLAN numbers assigned to the master VLANs. Also notice that no STP parameters are
configured for the groups of member VLANs. Each group of member VLANs will inherit its STP settings from its
master VLAN.
Set the bridge priority for each master VLAN to the highest priority (1) on one of the devices in the STP per VLAN
group configuration. By setting the bridge priority to the highest priority, you make the device the default root
bridge for the spanning tree. To ensure STP load balancing, make each of the devices the default root bridge for
a different master VLAN.
HP9300(config)# vlan-group 1 vlan 2 to 200
HP9300(config-vlan-group-1)# tag ethernet 1/1 ethernet 5/1 to 5/3
HP9300(config-vlan-group-1)# vlan-group 2 vlan 202 to 400
HP9300(config-vlan-group-2)# tag ethernet 1/2 ethernet 5/1 to 5/3
HP9300(config-vlan-group-2)# vlan-group 3 vlan 402 to 600
HP9300(config-vlan-group-2)# tag ethernet 1/3 ethernet 5/1 to 5/3
...
HP9300(config-vlan-group-19)# vlan-group 20 vlan 3082 to 4000
HP9300(config-vlan-group-20)# tag ethernet 1/20 ethernet 5/1 to 5/3
HP9300(config-vlan-group-20)# exit
The following group of commands configures the STP groups. Each STP group in this configuration contains one
master VLAN, which contains a VLAN group. This example shows that an STP group also can contain additional
VLANs (VLANs not configured in a VLAN group).
HP9300(config)# stp-group 1
HP9300(config-stp-group-1)# master-vlan 1
HP9300(config-stp-group-1)# member-group 1
HP9300(config-stp-group-1)# member-vlan 4001 4004 to 4010
HP9300(config-stp-group-1)# stp-group 2
HP9300(config-stp-group-2)# master-vlan 201
HP9300(config-stp-group-2)# member-group 2
HP9300(config-stp-group-2)# member-vlan 4002 4003 4011 to 4015
HP9300(config-stp-group-2)# stp-group 3
HP9300(config-stp-group-3)# master-vlan 401
HP9300(config-stp-group-3)# member-group 3
...
HP9300(config-stp-group-19)# stp-group 20
HP9300(config-stp-group-20)# master-vlan 3081
HP9300(config-stp-group-20)# member-group 20

PVST/PVST+ Compatibility

The following sections describe the Per VLAN Spanning Tree (PVST) and PVST+ compatibility features on HP
devices. Use the section that matches the software release you are using:
• For release 07.6.04 and later, see "PVST/PVST+ Compatibility – 07.6.04 and Later".
• For releases 07.1.10 – 07.6.00, see "PVST/PVST+ Compatibility – Earlier Than 07.6.01b" on page 8-81.
PVST/PVST+ Compatibility – 07.6.04 and Later
Software release 07.6.04 enhances HP support for Cisco's Per VLAN Spanning Tree plus (PVST+), by allowing
an HP device to run multiple spanning trees (MSTP) while also interoperating with IEEE 802.1Q devices
1.Cisco user documentation for PVST/PVST+ refers to the IEEE 802.1Q spanning tree as the Common
Spanning Tree (CST) .
