Configuring a topology group

To configure a topology group, enter commands such as the following.
PowerConnect(config)#topology-group 2
PowerConnect(config-topo-group-2)#master-vlan 2
PowerConnect(config-topo-group-2)#member-vlan 3
PowerConnect(config-topo-group-2)#member-vlan 4
PowerConnect(config-topo-group-2)#member-vlan 5
PowerConnect(config-topo-group-2)#member-group 2
These commands create topology group 2 and add the following:
•
•
•
Syntax: [no] topology-group <group-id>
The <group-id> parameter specifies the topology group ID and can be from 1 – 256.
Syntax: [no] master-vlan <vlan-id>
This command adds the master VLAN. The VLAN must already be configured. Make sure all the
Layer 2 protocol settings in the VLAN are correct for your configuration before you add the VLAN to
the topology group. A topology group can have only one master VLAN.
NOTE
If you remove the master VLAN (by entering no master-vlan <vlan-id>), the software selects the new
master VLAN from member VLANs. For example, if you remove master VLAN 2 from the example
above, the CLI converts member VLAN 3 into the new master VLAN. The new master VLAN inherits
the Layer 2 protocol settings of the older master VLAN.
NOTE
If you add a new master VLAN to a topology group that already has a master VLAN, the new master
VLAN replaces the older master VLAN. All member VLANs and VLAN groups follow the Layer 2
protocol settings of the new master VLAN.
Syntax: [no] member-vlan <vlan-id>
The <vlan-id> parameter specifies a VLAN ID. The VLAN must already be configured.
Syntax: [no] member-group <num>
The <num> specifies a VLAN group ID. The VLAN group must already be configured.

If you remove the master VLAN (by entering no master-vlan <vlan-id>), the software selects the
new master VLAN from member VLANs. A new candidate master VLAN will be in configured
order to a member VLAN so that the first added member VLAN will be a new candidate master
VLAN. Once you save and reload, a member-vlan with the youngest VLAN ID will be the new
candidate master. The new master VLAN inherits the Layer 2 protocol settings of the older
master VLAN.
Once you add a VLAN as a member of a topology group, all the Layer 2 protocol information on
the VLAN is deleted.
