Cisco Cisco 2000 Series Wireless LAN Controller

Cisco 2000 series controllers support 802.3 bridging in software release 3.2.116.21. This feature is 
disabled by default. However, you can enable or disable it through the controller CLI by entering this 
command:

config network 802.3-bridging {enable | disable}

When 802.3 bridging is enabled, all of the 802.3 frames are forwarded to or from the client. The original 
LLC/SNAP and length of the frame is preserved during encapsulation or de-capsulation of the LWAPP data 
frame. For short frames, the trailer is stripped before adding the LWAPP header. Tunneling of 802.3 frames 
is not supported.

802.3 bridging is supported only on 2000 series controllers and can be enabled or disabled only through 
the CLI.

DHCP proxy is configurable in software release 3.2.116.21 using the following command:

config dhcp proxy {enable | disable}

When you choose the disable option, modification of the dhcp proxy packets is reduced to the level of a 
relay.

Two new LWAPP power injector commands are available in software release 3.2.116.21. These 
commands are used when the access point is powered by a power injector that is connected to a Cisco 
pre-Intelligent Power Management (pre-IPM) switch. 

This command is recommended when the customer’s network contains any older Cisco 6-Watt 
switches that could be accidentally overloaded if connected directly to the 12-Watt access point. The 
access point remembers that a power injector is connected to this particular switch port. If the access 
point is relocated, this command must be re-issued after the presence of a new power injector is 
verified.

This command is acceptable to use when the customer’s network does not contain any older Cisco 
6-Watt switches that could be overloaded if connected directly to the 12-Watt access point. The 
access point assumes that a power injector is always connected. If the access point is relocated, it 
continues to assume that a power injector is present.
