Page 125: Static Route
H A P T E R 10.1 Overview The ZyXEL Device usually uses the default gateway to route outbound traffic from computers on the LAN to the Internet. To have the ZyXEL Device send data to devices not reachable through the default gateway, use static routes. For example, the next figure shows a computer (A) connected to the ZyXEL Device’s LAN interface.

H A P T E R Quality of Service (QoS) 11.1 Overview Quality of Service (QoS) refers to both a network’s ability to deliver data with minimum delay, and the networking methods used to control the use of bandwidth. Without QoS, all traffic data is equally likely to be dropped when the network is congested.
Page 130: What You Need To Know
Chapter 11 Quality of Service (QoS) 11.2 What You Need to Know The following terms and concepts may help as you read through this chapter. QoS versus Cos QoS is used to prioritize source-to-destination traffic flows. All packets in the same flow are given the same priority.

Page 138 Chapter 11 Quality of Service (QoS) IEEE 802.1Q Tag The IEEE 802.1Q standard defines an explicit VLAN tag in the MAC header to identify the VLAN membership of a frame across bridges. A VLAN tag includes the 12-bit VLAN ID and 3-bit user priority. The VLAN ID associates a frame with a specific VLAN and provides the information that devices need to process the frame across the network.
Page 139 Chapter 11 Quality of Service (QoS) DSCP and Per-Hop Behavior DiffServ defines a new Differentiated Services (DS) field to replace the Type of Service (TOS) field in the IP header. The DS field contains a 2-bit unused field and a 6-bit DSCP field which can define up to 64 service levels. The following figure illustrates the DS field.

Page 235: Appendix C Ip Addresses And Subnetting
P P E N D I X IP Addresses and Subnetting This appendix introduces IP addresses and subnet masks. IP addresses identify individual devices on a network. Every networking device (including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network.
Page 236: Subnet Masks
Appendix C IP Addresses and Subnetting The following figure shows an example IP address in which the first three octets (192.168.1) are the network number, and the fourth octet (16) is the host ID. Figure 150 Network Number and Host ID How much of the IP address is the network number and how much is the host ID varies according to the subnet mask.
Page 237 By convention, subnet masks always consist of a continuous sequence of ones beginning from the leftmost bit of the mask, followed by a continuous sequence of zeros, for a total number of 32 bits. Subnet masks can be referred to by the size of the network number part (the bits with a “1”...
Page 238 Appendix C IP Addresses and Subnetting Notation Since the mask is always a continuous number of ones beginning from the left, followed by a continuous number of zeros for the remainder of the 32 bit mask, you can simply specify the number of ones instead of writing the value of each octet.
Page 239 Appendix C IP Addresses and Subnetting The following figure shows the company network before subnetting. Figure 151 Subnetting Example: Before Subnetting You can “borrow” one of the host ID bits to divide the network 192.168.1.0 into two separate sub-networks. The subnet mask is now 25 bits (255.255.255.128 or /25).
Page 240 Appendix C IP Addresses and Subnetting The following figure shows the company network after subnetting. There are now two sub-networks, A and B. Figure 152 Subnetting Example: After Subnetting In a 25-bit subnet the host ID has 7 bits, so each sub-network has a maximum of –...
Page 241 Each subnet contains 6 host ID bits, giving 2 host ID of all zeroes is the subnet itself, all ones is the subnet’s broadcast address). Table 63 Subnet 1 IP/SUBNET MASK IP Address (Decimal) IP Address (Binary) Subnet Mask (Binary) Subnet Address: 192.168.1.0 Broadcast Address:...
Page 242 Appendix C IP Addresses and Subnetting Table 66 Subnet 4 (continued) IP/SUBNET MASK Subnet Address: 192.168.1.192 Broadcast Address: 192.168.1.255 Example: Eight Subnets Similarly, use a 27-bit mask to create eight subnets (000, 001, 010, 011, 100, 101, 110 and 111). The following table shows IP address last octet values for each subnet.
Page 243 The following table is a summary for subnet planning on a network with a 16-bit network number. Table 69 16-bit Network Number Subnet Planning NO. “BORROWED” HOST BITS Configuring IP Addresses Where you obtain your network number depends on your particular situation. If the ISP or your network administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask.
Page 244 Appendix C IP Addresses and Subnetting address that you entered. You don't need to change the subnet mask computed by the ZyXEL Device unless you are instructed to do otherwise. Private IP Addresses Every machine on the Internet must have a unique address. If your networks are isolated from the Internet (running only between two branch offices, for example) you can assign any IP addresses to the hosts without problems.
Page 245 address to computer A or setting computer A to obtain an IP address automatically. Figure 153 Conflicting Computer IP Addresses Example Conflicting Router IP Addresses Example Since a router connects different networks, it must have interfaces using different network numbers. For example, if a router is set between a LAN and the Internet (WAN), the router’s LAN and WAN addresses must be on different subnets.
Page 246 Appendix C IP Addresses and Subnetting The computer cannot access the Internet. This problem can be solved by assigning a different IP address to the computer or the router’s LAN port. Figure 155 Conflicting Computer and Router IP Addresses Example P-870HW-51a v2 User’s Guide...
Page 247: Appendix D Wireless Lans
P P E N D I X Wireless LAN Topologies This section discusses ad-hoc and infrastructure wireless LAN topologies. Ad-hoc Wireless LAN Configuration The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with wireless adapters (A, B, C). Any time two or more wireless adapters are within range of each other, they can set up an independent network, which is commonly referred to as an ad-hoc network or Independent Basic Service Set (IBSS).
Page 248 Appendix D Wireless LANs with each other. When Intra-BSS is disabled, wireless client A and B can still access the wired network but cannot communicate with each other. Figure 157 Basic Service Set An Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an access point, with each access point connected together by a wired network.
Page 249 An ESSID (ESS IDentification) uniquely identifies each ESS. All access points and their associated wireless clients within the same ESS must have the same ESSID in order to communicate. Figure 158 Infrastructure WLAN Channel A channel is the radio frequency(ies) used by wireless devices to transmit and receive data.
Page 250 Appendix D Wireless LANs wireless gateway, but out-of-range of each other, so they cannot "hear" each other, that is they do not know if the channel is currently being used. Therefore, they are considered hidden from each other. Figure 159 RTS/CTS When station A sends data to the AP, it might not know that the station B is already using the channel.
Page 251: Fragmentation Threshold
Fragmentation Threshold A Fragmentation Threshold is the maximum data fragment size (between 256 and 2432 bytes) that can be sent in the wireless network before the AP will fragment the packet into smaller data frames. A large Fragmentation Threshold is recommended for networks not prone to interference while you should set a smaller threshold for busy networks or networks that are prone to interference.
Page 252 Appendix D Wireless LANs several intermediate rate steps between the maximum and minimum data rates. The IEEE 802.11g data rate and modulation are as follows: Table 70 IEEE 802.11g DATA RATE (MBPS) 5.5 / 11 6/9/12/18/24/36/ 48/54 Wireless Security Overview Wireless security is vital to your network to protect wireless communication between wireless clients, access points and the wired network.
Page 253 IEEE 802.1x In June 2001, the IEEE 802.1x standard was designed to extend the features of IEEE 802.11 to support extended authentication as well as providing additional accounting and control features. It is supported by Windows XP and a number of network devices.
Page 254: Types Of Eap Authentication
Appendix D Wireless LANs • Access-Challenge Sent by a RADIUS server requesting more information in order to allow access. The access point sends a proper response from the user and then sends another Access-Request message. The following types of RADIUS messages are exchanged between the access point and the RADIUS server for user accounting: •...
Page 255 However, MD5 authentication has some weaknesses. Since the authentication server needs to get the plaintext passwords, the passwords must be stored. Thus someone other than the authentication server may access the password file. In addition, it is possible to impersonate an authentication server as MD5 authentication method does not perform mutual authentication.
Page 256: Dynamic Wep Key Exchange
Appendix D Wireless LANs Dynamic WEP Key Exchange The AP maps a unique key that is generated with the RADIUS server. This key expires when the wireless connection times out, disconnects or reauthentication times out. A new WEP key is generated each time reauthentication is performed. If this feature is enabled, it is not necessary to configure a default encryption key in the wireless security configuration screen.
Page 257 If the AP or the wireless clients do not support WPA2, just use WPA or WPA-PSK depending on whether you have an external RADIUS server or not. Select WEP only when the AP and/or wireless clients do not support WPA or WPA2. WEP is less secure than WPA or WPA2.
Page 258 Appendix D Wireless LANs keys. This prevent all wireless devices sharing the same encryption keys. (a weakness of WEP) User Authentication WPA and WPA2 apply IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate wireless clients using an external RADIUS database. WPA2 reduces the number of key exchange messages from six to four (CCMP 4-way handshake) and shortens the time required to connect to a network.
Page 259 The RADIUS server distributes the PMK to the AP. The AP then sets up a key hierarchy and management system, using the PMK to dynamically generate unique data encryption keys. The keys are used to encrypt every data packet that is wirelessly communicated between the AP and the wireless clients.
Page 260: Security Parameters Summary
Appendix D Wireless LANs The AP and wireless clients use the TKIP or AES encryption process, the PMK and information exchanged in a handshake to create temporal encryption keys. They use these keys to encrypt data exchanged between them. Figure 161 WPA(2)-PSK Authentication Security Parameters Summary Refer to this table to see what other security parameters you should configure for each authentication method or key management protocol type.
Page 261: Antenna Characteristics
Antenna Overview An antenna couples RF signals onto air. A transmitter within a wireless device sends an RF signal to the antenna, which propagates the signal through the air. The antenna also operates in reverse by capturing RF signals from the air. Positioning the antennas properly increases the range and coverage area of a wireless LAN.
Page 262 Appendix D Wireless LANs • Omni-directional antennas send the RF signal out in all directions on a horizontal plane. The coverage area is torus-shaped (like a donut) which makes these antennas ideal for a room environment. With a wide coverage area, it is possible to make circular overlapping coverage areas with multiple access points.
