VLAN Groups

To simplify configuration when you have many VLANs with the same configuration, you can configure VLAN groups.

Note: VLAN groups are supported on Layer 3 Switches and Layer 2 Switches.

When you create a VLAN group, the VLAN parameters you configure for the group apply to all the VLANs within the group. The VLAN group feature allows you to create multiple port-based VLANs with identical port members. Because the member ports are shared by all the VLANs within the group, you must add the ports as tagged ports. This feature not only simplifies VLAN configuration but also allows you to have a large number of identically configured VLANs in a startup-config file on the device flash memory module. Normally, a startup-config file with a large number of VLANs might not fit on the flash memory module. By grouping the identically configured VLANs, you can conserve space in the startup-config file so that it fits on the flash memory module. You can create up to 32 VLAN groups.

Note: Depending on the size of the VLAN ID range you want to use for the VLAN group, you might need to allocate additional memory for VLANs.
