Creating and Modifying VLANs
Configuring UNI VLANs
By default, every VLAN configured on the switch is a UNI isolate d VL A N. You can change VLAN
configuration to that of a UNI community VLAN, a private VLAN. or an RSPAN VLAN. You can also
change the configuration of one of these VLANs to the default of a UNI isolated VLAN.

Configuration Guidelines

These are guidelines for UNI VLAN configuration:
•UNI isolated VLANs have no effect on NNI ports.
•A UNI community VLAN is like a traditional VLAN except that it can include no more than eight
UNIs.
To change a VLAN type, first enter the vlan vlan-id global configuration command to enter VLAN
configuration mode:
–
To change a VLAN from UNI isolated VLAN to a private VLAN, enter th e private-vlan VLAN
configuration command.
–
To change a UNI community VLAN to a private VLAN, you must first remove the community
VLAN type by entering the no uni-vlan VLAN configuration command. Then enter the
private-vlan VLAN configuration command.
–
To change a VLAN from a UNI isolated VLAN to an RSPAN VLAN, enter the rspan-vlan
VLAN configuration command.
–
To change a UNI community VLAN to an RSP AN VLAN, you must first remo ve the communi ty
VLAN type by entering the no uni-vlan VLAN configuration command. Then enter the
rspan-vlan VLAN configuration command.
–
To change a private VLAN to a UNI VLAN, you must first remove the private VLAN type by
entering the no private-vlan VLAN configuration command. Then ent er t he uni-vlan VLAN
configuration command.
–
To change an RSPAN VLAN to a UNI VLAN, you must first remove the RSPAN VLAN type
by entering the no rspan-vlan VLAN configuration command. Then enter the uni-vlan VLAN
configuration command
•The switch does not support more than eight UNIs in a community VLAN. You cannot configure a
VLAN as a UNI community VLAN if more than eight UNIs belong to the VLAN.
•If you attempt to add a UNI static access port to a UNI community VLAN that already has eight
UNIs, the configuration is refused. If a UNI dynamic access port is added to a UNI community
VLAN that already has eight UNIs, the port is error-disabled.
