VLAN Management
VLANs
Cisco Small Business 300 Series Managed Switch Administration Guide 109

Adjacent VLAN-aware devices exchange VLAN information with each other by
using Generic VLAN Registration Protocol (GVRP). As a result, VLAN information is
propagated through a bridged network.
VLANs on a device can be created statically or dynamically, based on the GVRP
information exchanged by devices. A VLAN can be static or dynamic (from GVRP),
but not both. For more information about GVRP, refer to the GVRP Settings section.
Some VLANs can have additional roles, including:
• Voice VLAN: For more information refer to the Voice VLAN section.
• Guest VLAN: Set in the Edit VLAN Authentication Page.
• Default VLAN: For more information refer to the Configuring Default VLAN
Settings section.
• Management VLAN (in Layer 2-mode systems): For more information refer
to the Layer 2 IP Addressing section.
VLAN Configuration Workflow
To configure VLANs:
1. If required, change the default VLAN by using the Configuring Default VLAN
Settings section.
2. Create the required VLANs by using the Creating VLANs section.
3. Set the desired per port VLAN-related configuration using the Configuring
VLAN Interface Settings section.
4. Assign interfaces to VLANs by using the Configuring Port to VLAN section or
the Configuring VLAN to Port section.
5. You can view the current VLAN port membership for all the interfaces in the
Viewing VLAN Membership section.
