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 10-2 shows the default VLAN configuration values.
Note Catalyst 4500 series switches do not support Token Ring or FDDI media. The switch does not forward
FDDI, FDDI-NET, TrCRF, or TrBRF traffic, but it does propagate the VLAN configuration via VTP. The
software reserves parameters for these media types, but they are not trul y supported.
Configuring VLANs
Note Before you configure VLANs, you must use VLAN Trunking Protocol (VTP) to maintain g lobal VLAN
configuration information for your network. For complete infor mation on VTP, see Chapter27,
“Understanding and Configuring VTP.”
