Protecting Your Wireless LAN
To prevent unauthorized access to your network, you must configure security settings. Because the
bridge is a radio device, the bridge communicates beyond the physical boundaries of your building.
Refer to the Cisco Aironet 1400 Series Wireless Bridge Software Configuration Guide to configure
security features to protect your network from intruders:
• Unique SSIDs that are not broadcast in the bridge beacon
• WEP and additional WEP features, such as TKIP and broadcast key rotation
• Dynamic WEP and EAP authentication
Assigning an IP Address Using the CLI
When you connect the bridge to the wired LAN, the bridge links to the network using a bridge virtual
interface (BVI) that it creates automatically. Instead of tracking separate IP addresses for the bridge's
Ethernet and radio ports, the network uses the BVI.
When you assign an IP address to the bridge using the CLI, you must assign the address to the BVI.
Beginning in privileged EXEC mode, follow these steps to assign an IP address to the bridge's BVI:
Command
configure terminal
Step 1
interface bvi1
Step 2
Step 3
ip address address
mask
Using a Telnet Session to Access the CLI
Follow these steps to access the CLI using a Telnet session. These steps are for a PC running Microsoft
Windows with a Telnet terminal application. Check your PC operating instructions for detailed
instructions for your operating system.
THIRD FCC DRAFT (CISCO CONFIDENTIAL)
Purpose
Enter global configuration mode.
Enter interface configuration mode for the BVI.
Assign an IP address and address mask to the BVI. This step
automatically saves the running configuration to the startup
configuration.
Note
You lose your connection to the bridge when you
assign a new IP address to the BVI. If you need to
continue configuring the bridge, use the new IP
address to open another Telnet session to the
bridge.
