Configuring STP related features
8
Here are the CLI commands for implementing the STP per VLAN group configuration shown in
Figure 51. 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.
PowerConnect(config)#vlan 2
PowerConnect(config-vlan-2)#spanning-tree priority 1
PowerConnect(config-vlan-2)#tagged ethernet 1/1 to 1/4
PowerConnect(config-vlan-2)#vlan 3
PowerConnect(config-vlan-3)#tagged ethernet 1/1 to 1/4
PowerConnect(config-vlan-3)#vlan 4
PowerConnect(config-vlan-4)#tagged ethernet 1/1 to 1/4
PowerConnect(config-vlan-4)#vlan 12
PowerConnect(config-vlan-12)#spanning-tree priority 2
PowerConnect(config-vlan-12)#tagged ethernet 1/1 to 1/4
PowerConnect(config-vlan-12)#vlan 13
PowerConnect(config-vlan-13)#tagged ethernet 1/1 to 1/4
PowerConnect(config-vlan-13)#vlan 14
PowerConnect(config-vlan-14)#tagged ethernet 1/1 to 1/4
PowerConnect(config-vlan-14)#exit
The following commands configure the STP groups.
PowerConnect(config)#stp-group 1
PowerConnect(config-stp-group-1)#master-vlan 2
PowerConnect(config-stp-group-1)#member-vlan 3 to 4
PowerConnect(config-stp-group-1)#exit
PowerConnect(config)#stp-group 2
PowerConnect(config-stp-group-2)#master-vlan 12
PowerConnect(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.
NOTE
If you delete the master VLAN from an STP group, the software automatically assigns the first
member VLAN in the group to be the new master VLAN for the group.
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,
refer to “Configuration example for STP load sharing”.
