You work as a network technician at Company.com. Your boss, is interested in LWAPP
(Lightweight Access Point Protocol). What should you tell her regarding this technology?
(Select 2)
A.
LWAPP is a proprietary protocol, and because of its very high overhead it is not
widely adopted.
B.
Control traffic is encapsulated in UDP packets with a source port of 1024 and a
destination port of 12223.
C.
Layer 3 LWAPP is a UDP/IP Frame that requires a Cisco Aironet AP to obtain an IP
address using DHCP.
D.
Data traffic is encapsulated in UDP packets with a source port of 1024 and a
destination port of 12223.
E.
Control traffic is encapsulated in TCP packets with a source port of 1024 and a
destination port of 12223.
F.
Data traffic is encapsulated in TCP packets with a source port of 1024 and a
destination port of 12223.
Explanation:
For Layer 3, LWAPP uses packets in a UDP/IP frame. LWAPP control traffic uses source
port 1024 or greater and destination port 12223, and LWAPP data traffic uses source port
1024 or greater and destination port 12222. The Cisco wireless LAN controller and access
point can be connected to the same VLAN/subnet or to a different VLAN/subnet.
In Layer 3 operation, the access point and the controller can be on the same or different
subnets. Layer 3 operation is scalable and is recommended by Cisco. A Layer 3 access
point on a different subnet than the controller requires a DHCP server on the access point
subnet and a route to the controller. The route to the controller must have destination UDP
ports 12222 and 12223 open for LWAPP communications. The route to the primary,
secondary, and tertiary controllers must allow IP packet fragments.
