STP (Spanning Tree

Protocol) / RSTP (Rapid

STP)

(R)STP detects and breaks network loops and provides backup links

between switches, bridges or routers. It allows a bridge to interact with

other (R)STP-compliant bridges in your network to ensure that only one

path exists between any two stations on the network.

WMM QoS

WMM (Wi-Fi MultiMedia) QoS (Quality of Service) allows you to prioritize

wireless traffic.

Certificates

The ZyXEL Device can use certificates (also called digital IDs) to

authenticate users. Certificates are based on public-private key pairs.

Certificates provide a way to exchange public keys for use in

authentication.

SSL Passthrough

SSL (Secure Sockets Layer) uses a public key to encrypt data that's

transmitted over an SSL connection. Both Netscape Navigator and

Internet Explorer support SSL, and many Web sites use the protocol to

obtain confidential user information, such as credit card numbers. By

convention, URLs that require an SSL connection start with “https”

instead of “http”. The ZyXEL Device allows SSL connections to take

place through the ZyXEL Device.

MAC Address Filter

Your ZyXEL Device checks the MAC address of the wireless station

against a list of allowed or denied MAC addresses.

Wireless Association List

With the wireless association list, you can see the list of the wireless

stations that are currently using the ZyXEL Device to access your wired

network.

Logging and Tracing

Built-in message logging and packet tracing.

Embedded FTP and TFTP

Servers

The embedded FTP and TFTP servers enable fast firmware upgrades

as well as configuration file backups and restoration.

Auto Configuration

Administrators can use text configuration files to configure the wireless

LAN settings for multiple APs. The AP can automatically get a

configuration file from a TFTP server at start up or after renewing DHCP

client information.

SNMP

SNMP (Simple Network Management Protocol) is a protocol used for

exchanging management information between network devices. SNMP

is a member of the TCP/IP protocol suite. Your ZyXEL Device supports

SNMP agent functionality, which allows a manger station to manage and

monitor the ZyXEL Device through the network. The ZyXEL Device

supports SNMP version one (SNMPv1) and version two c (SNMPv2c).

The NWA-3165 also supports version 3 (SNMPv3).

DFS

DFS (Dynamic Frequency Selection) allows a wider choice of 802.11a

wireless channels.

CAPWAP (Control and

Provisioning of Wireless

Access Points)

The ZyXEL Device can be managed via CAPWAP, which allows multiple

APs to be configured and managed by a single AP controller.
