    (like the Internet). The NOA-3570 allows VPN connections to go through it. Wireless LAN MAC Address Filtering Your NOA-3570 checks the MAC address of the wireless station against a list of allowed or denied MAC addresses. WEP Encryption WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless network to help keep network communications private.

  • Page 26: Applications For The Noa-3570

    1.3.1 Access Point The NOA-3570 is an ideal access solution for wireless Internet connection. A typical Internet access application for your NOA-3570 is shown as follows. Stations A, B and C can access the wired network through the NOA-3570s. Chapter 1 Getting to Know Your NOA-3570...

    Wireless security is vital to your network to protect wireless communication between wireless stations, access points and the wired network. Wireless security methods available on the NOA-3570 are data encryption, wireless client authentication, restricting access by device MAC address and hiding the NOA-3570 identity.

  • Page 49: Restricted Access

    (Allow Association) or exclude them from accessing the AP (Deny Association). 5.2.4 Hide NOA-3570 Identity If you hide the SSID, then the NOA-3570 cannot be seen when a wireless client scans for local APs. The trade-off for the extra security of “hiding” the NOA-3570 may be inconvenience for some valid WLAN clients.

  • Page 50: Spanning Tree Protocol (Stp)

    5.3.1 Rapid STP The NOA-3570 uses IEEE 802.1w RSTP (Rapid Spanning Tree Protocol) that allow faster convergence of the spanning tree (while also being backwards compatible with STP-only aware bridges).

  • Page 51: How Stp Works

    NOA-3570 User’s Guide 5.3.3 How STP Works After a bridge determines the lowest cost-spanning tree with STP, it enables the root port and the ports that are the designated ports for connected LANs, and disables all other ports that participate in STP. Network packets are therefore only forwarded between enabled ports, eliminating any possible network loops.
