Configuring VLANs
When you create or modify an Ethernet VLAN, note the following information:
RPR+ redundancy does not support a configuration entered in VLAN database mode. Use global
•
configuration mode with RPR+ redundancy.
•
Because Layer 3 ports and some software features require internal VLANs allocated from 1006 and
up, configure extended-range VLANs starting with 4094.
You can configure extended-range VLANs only in global configuration mode. You cannot configure
•
extended-range VLANs in VLAN database mode.
Layer 3 ports and some software features use extended-range VLANs. If the VLAN you are trying
•
to create or modify is being used by a Layer 3 port or a software feature, the router displays a
message and does not modify the VLAN configuration.
When deleting VLANs, note the following information:
You cannot delete the default VLANs for the different media types: Ethernet VLAN 1 and FDDI or
•
Token Ring VLANs 1002 to 1005.
When you delete a VLAN, any LAN ports configured as access ports assigned to that VLAN become
•
inactive. The ports remain associated with the VLAN (and inactive) until you assign them to a new
VLAN.
This example shows how to create an Ethernet VLAN in global configuration mode and verify the
configuration:
Router# configure terminal
Router(config)# vlan 3
Router(config-vlan)# end
Router# show vlan id 3
