Configuring Bridge Groups Using the 12E/2FE VLAN Configuration WebTool
The 12E/2FE VLAN Configuration WebTool, shown in Figure 2, is a web browser-based Java applet that
displays configured interfaces and bridge groups for PA-12E/2FE port adapters installed in Cisco
routers. With the WebTool you can perform the following tasks:
• Create and delete bridge groups (also referred to as VLANs)
• Add and remove PA-12E/2FE interfaces from bridge groups
• Assign colors to bridge groups and PA-12E/2FE interfaces
• Administratively shut down (disable) and bring up (enable) PA-12E/2FE interfaces
• View the bridge-group status of each PA-12E/2FE interface
