Configuring Single-Instance Spanning Tree Protocol (STP)
Beginning with software release 05.2.14, you can configure either single-instance or multiple-instance spanning tree
on the HP 9304M, 9308M, and 6308M-SX routing switches, and the HP 6208M-SX Switch. When single-instance STP is
enabled, all VLANS on the device belong to the same spanning tree VLAN—with a shared STP VLAN ID of 4094. When
multi-instance STP is used, each VLAN has a unique spanning tree ID.
To enable single-instance STP:
1.
Enable single-instance STP globally.
2.
Enable STP on each interface on which you want STP to operate.
•
On the 9304M, 9308M, and 6308M-SX routing switches, you can enable STP on a per port or per VLAN
basis.
•
On the 6208M switch, enabling single-instance STP initially applies to all VLANs in the switch. You can
use the no spanning tree command to disable STP on individual VLANs in the switch.
Example of Single-Instance STP Configuration: Beginning at the User EXEC level of the CLI, execute the
following:
HP9308>enable
HP9308#configure terminal
HP9308(config)#spanning-tree single
HP9308#wr mem
HP9308(config)#vlan 100
HP9308(config-vlan-100)#span
HP9308(config)#wr mem
After executing the above commands, the show config command will list the following VLAN/STP information:
ver 05.2.1x
!
span single
!
vlan 100 by port
tagged ethe 3/1 to 3/2
span
!
vlan 101 by port
tagged ethe 3/1 to 3/2
no span

Enables single-instance STP globally.
Saves the configuration change to memory.
Single instance STP must be enabled for each VLAN that participates in the
spanning-tree algorithm. The configuration file will show whether STP is enabled
for a specific VLAN. In the following example, VLAN 100 is configured for STP
(participating in the STP algorithm), while VLAN 101 is not.
Continuing from above, this command enables single-instance STP on VLAN 100.
("100" is the <vlan ID>.)
Saves the configuration change to memory.
Shows the software version number for the device.
Indicates single-instance STP is enabled on the device.
"span" indicates single-instance STP is configured on VLAN 100.
(Note: on the 6208M-XS switch, the word "span" does not appear, even though the
device has been enabled for that VLAN.)
"no span" indicates that STP is not configured on VLAN 101.
