4.1.3

CAPWAP Configuration

A secured tunnel is created between APC and W-EP wireless LAN AP using Control And
Provisioning Wireless Access Point (CAPWAP), i.e. a standard protocol, and data is
transmitted through the tunnel. An encrypted data is used for both wire and wireless
sections, high security is provided.
The CAPWAP channel consists of control channel and data channel depending on the type
of packet being transmitted/received. The control channel handles provisioning and
configuration/control messages and the data channel transmits the data traffic exchanged
with a wireless terminal through CAPWAP tunneling. Because the control channel
transmits the wireless LAN configuration information, there should be no data loss.
Therefore, the re-transmission function is basically provided. In addition, the Datagram
Transmission Layer Security (DTLS) is mandatorily used for the security of transmitted
data. Meanwhile, as user data traffic is transmitted through the data channel, a faster
response is preferred instead of packet transmission reliability. Therefore, the re-
transmission function is not provided and the DTLS function is also optional.
For CAPWAP configuration, execute the following commands.
1) Go to configure  apc capwap of CLI.
WEC8500# configure terminal

WEC8500/configure# apc

WEC8500/configure/apc/capwap#
2) Configure the CAPWAP function using the following commands.

add-multicast-if [VLAN_ID]: Configure a VLAN ID for multicast interface.

auto-discovery: Configures the function of automatically detecting and registering
an AP.

auto-discovery-ap-group [AP_GROUP_ID]: Configures an AP group that will be
working when an AP is automatically registered.

change-state-pending-timer [TIMER]: Configures the maximum waiting time until
the APC receives the Change State Event Request message from an AP after
transmitting the Configuration Status Response message to the AP (RFC 5415).

ctr-src-port [port]: Changes the CAPWAP Control port (RFC5415).

date-check-timer [TIMER]: Configures the maximum waiting time until the APC
receives Data Channel Keep-alive (default: 30 seconds)

discovery-by-broadcast: Configures whether to allow connection to CAPWAP
broadcast.

discovery-by-multicast: Configures whether to allow connection to CAPWAP
multicast. (The 'add-multicast-if' must be configured before configuring whether to
allow multicast connection.)
