Command Modes VLAN configuration
Command History
Usage Guidelines Before configuring private VLANs, you must disable VTP (VTP mode transparent). After you configure
a private VLAN, you should not change the VTP mode to client or server.
VTP does not propagate private-VLAN configuration. You must manually configure private VLANs on
all switches in the Layer 2 network to merge their Layer 2 databases and to prevent flooding of
private-VLAN traffic.
You cannot include VLAN 1 or VLANs 1002 to 1005 in the private-VLAN configuration. Extended
VLANs (VLAN IDs 1006 to 4094) can be configured in private VLANs.
association Create an association between the primary VLAN and a secondary VLAN.
secondary-vlan-list Specify one or more secondary VLANs to be associated with a primary
VLAN in a private VLAN.
add Associate a secondary VLAN to a primary VLAN.
remove Clear the association between a secondary VLAN and a primary VLAN.
community Designate the VLAN as a community VLAN.
isolated Designate the VLAN as a community VLAN.
primary Designate the VLAN as a community VLAN.
