This is the power required at the PSE, which is either a switch or an injector. You cannot configure power levels independently for When you connect the wireless device to the wired LAN, the wireless device links to the network using a bridge virtual interface BVI that it creates automatically.
Note If you are connected to the wireless device using a Telnet session, you lose your connection to the wireless device when you assign a new IP address to the BVI. If you need to continue configuring the wireless device using Telnet, use the new IP address to open another Telnet session to the wireless device.
Follow these steps to access the CLI by using a Telnet session. Check your PC operating instructions for detailed instructions for your operating system. Note In Windows , the Telnet window does not contain drop-down lists. To start the Telnet session in Windows , type open followed by the wireless device IP address.
First, access points can be placed in public places, inviting the possibility that they could be unplugged and their network connection used by an outsider. Second, when a repeater access point is incorporated into a wireless network, the repeater access point must authenticate to the root access point in the same way as a client does. You can complete the phases in any order, but they must be completed before the supplicant becomes operational. Beginning in privileged EXEC mode, follow these steps to create an Creates a dot1x credentials profile and enters the dot1x credentials configuration submode.
Optional —Enter the anonymous identity to be used. Optional —Enter a description for the credentials profile. Enter an unencrypted password for the credentials. Hidden passwords are used when applying a previously saved configuration.
Note Unencrypted and clear text are the same. You can enter a 0 followed by the clear text password, or omit the 0 and enter the clear text password.
Optional Save your entries in the configuration file. Use the no form of the dot1x credentials command to negate a parameter. The following example creates a credentials profile named test with the username Cisco and a the unencrypted password Cisco:. Credential profiles are applied to an interface or an SSID in the same way. Beginning in the privileged EXEC mode, follow these steps to apply the credentials to the access point wired port:. Enter the interface configuration mode for the access point Gigabit Ethernet port.
