VLANs
Configurable Normal-Range VLAN Parameters
Note Ethernet VLANs 1 and 1006 through 4094 use only default values.
You can configure the following parameters for VLANs 2 through 1001:
• VLAN name
• VLAN type
• VLAN state (active or suspended)
• SAID
• STP type for VLANs
VLAN Default Configuration
Table 17-2 shows the default VLAN configuration values.
1002–1005 Normal Cisco defaults for FDDI and Token Ring. You cannot delete
VLANs 1002–1005.
Yes
1006–4094 Extended For Ethernet VLANs only. When configuring extended-range
VLANs, note the following:
• Layer 3 ports and some software features require internal
VLANs. Internal VLANs are allocated from 1006 and
up. You cannot use a VLAN that has been allocated for
such use. To display the VLANs used internally, enter the
show vlan internal usage command.
• Switches running the Catalyst operating system do not
support configuration of VLANs 1006-1024. If you
configure VLANs 1006-1024, ensure that the VLANs do
not extend to any switches running Catalyst operating
system software.
• You must enable the extended system ID to use extended
range VLANs.
No
