HP 9304m Installation And Getting Started Manual page 192

• Optionally, configure master VLANs to contain the member VLANs. This is useful when you have a lot of
member VLANs and you do not want to individually configure STP on each one. Each of the member VLANs
in a master VLAN uses the STP settings of the master VLAN.
• Configure the STP groups. Each STP group runs a separate instance of STP.
Here are the CLI commands for implementing the STP per VLAN group configuration shown in Figure 6.7. The
following commands configure the member VLANs (3, 4, 13, and 14) and the master VLANs (2 and 12). Notice
that changes to STP parameters are made in the master VLANs only, not in the member VLANs.
HP9300(config)# vlan 2
HP9300(config-vlan-2)# spanning-tree priority 1
HP9300(config-vlan-2)# tagged ethernet 1/1 ethernet to 1/4
HP9300(config-vlan-2)# vlan 3
HP9300(config-vlan-3)# tagged ethernet 1/1 ethernet to 1/4
HP9300(config-vlan-3)# vlan 4
HP9300(config-vlan-4)# tagged ethernet 1/1 ethernet to 1/4
HP9300(config-vlan-4)# vlan 12
HP9300(config-vlan-12)# spanning-tree priority 2
HP9300(config-vlan-12)# tagged ethernet 1/1 ethernet to 1/4
HP9300(config-vlan-12)# vlan 13
HP9300(config-vlan-13)# tagged ethernet 1/1 ethernet to 1/4
HP9300(config-vlan-13)# vlan 14
HP9300(config-vlan-14)# tagged ethernet 1/1 ethernet to 1/4
HP9300(config-vlan-14)# exit
The following commands configure the STP groups.
HP9300(config)# stp-group 1
HP9300(config-stp-group-1)# master-vlan 2
HP9300(config-stp-group-1)# member-vlan 3 to 4
HP9300(config-stp-group-1)# exit
HP9300(config)# stp-group 2
HP9300(config-stp-group-2)# master-vlan 12
HP9300(config-stp-group-2)# member-vlan 13 to 14
Syntax: [no] stp-group <num>
This command changes the CLI to the STP group configuration level. The following commands are valid at this
level. The <num> parameter specifies the STP group ID and can be from 1 – 32.
Syntax: [no] master-vlan <num>
This command adds a master VLAN to the STP group. The master VLAN contains the STP settings for all the
VLANs in the STP per VLAN group. The <num> parameter specifies the VLAN ID. An STP group can contain one
master VLAN.
Syntax: [no] member-vlan <num> [to <num>]
This command adds additional VLANs to the STP group. These VLANs also inherit the STP settings of the
master VLAN in the group.
Syntax: [no] member-group <num>
This command adds a member group (a VLAN group) to the STP group. All the VLANs in the member group
inherit the STP settings of the master VLAN in the group. The <num> parameter specifies the VLAN group ID.
NOTE: This command is optional and is not used in the example above. For an example of this command, see
"Configuration Example for STP Load Sharing".
