You have to enable the VLANs..
Here is the information from the Cisco handbook:
"A bridge group is a group of ports that form a single broadcast domain that is local to the switch. Bridge groups are a feature of the Catalyst 2820 series and Catalyst 1900 series standard software. The complete instructions to configure bridge groups are in the Catalyst 1900 Series Installation and Configuration Guide and the Catalyst 2820 Series Installation and Configuration Guide.
Bridge groups interact with the Enterprise Edition software in the following ways:
* When configuring the switch, you can use either bridge groups or VLANs. You cannot use both.
* By default, bridge groups are disabled and VLANs are enabled.
* If you enable bridge groups, the following features are disabled on the switch:
*
o All VLAN features
o Uplink Fast
o DISL
o Fast EtherChannel
* When you change from VLANs to bridge groups and vice versa, all options that you have configured are reset to their default settings. You will need to reconfigure any options that you need for VLANs or bridge groups.
To switch between VLANs and bridge groups, use the T option in the System Menu."
