Chapter 3: Operating Modes & Functional Features
In addition to performing standards-compliant AP functions, OTC Trimar-AP has many features
of convenience and it provides several modes of operation.
3.1 DHCP Client for Self
Dynamic Host Configuration Protocol client automatically gets IP address and DNS
addresses from the DHCP server. Wireless DHCP client can be configured to provide
host name to DHCP server for better management.
3.2 Wireless DHCP Server
Dynamic Host Configuration Protocol server that automatically assigns IP addresses to
wireless client stations logging onto a TCP/IP network. It eliminates having to manually
assign permanent IP addresses. DHCP server runs in Access Point and is capable of
assigning IP address only to wireless clients who is authorized to use the AP. DHCP
servers also dynamically update the DNS servers information when connected.
Source filtering
DHCP server will filter the request based upon source port, namely wireless, wired and
WDS.
3.3 WDS – Wireless Distribution System
Wireless Distribution System (WDS) allows packets to pass through without
modification from one wireless access point to another. This feature is especially
interesting to those who require transparent bridge because application only runs on a
wired Ethernet switch due to special network protocol it use. One throw back of using
this feature is one cannot use any of the stronger WPA authentication and encryption

Enable WDS - Enable or disable WDS.
WDS MAC - Up to 6 MAC addresses of adjacent WDS Access Point.
3.4 STP- Spanning Tree Protocol
Trimar-AP is equipped with STP. Spanning Tree Protocol is used in transparent
bridges to dynamically determine the best path from source to destination. It
avoids bridge loops (two or more paths linking one segment to another), which
can cause the bridges to send packets to wrong destination in infinite loop. This
protocol creates a hierarchical "tree" that "spans" the entire network including all
