CHAPTER 7
LAN and VLAN
7.1 LAN Overview
This chapter describes how you can configure the IP address of your NWA.
The Internet Protocol (IP) address identifies a device on a network. Every networking device
(including computers, servers, routers, printers, etc.) needs an IP address to communicate across
the network. These networking devices are also known as hosts.
Figure 41 IPv4 Setup
The figure above illustrates one possible setup of your NWA. The gateway IPv4 address is
192.168.1.1 and the IPv4 address of the NWA is 192.168.1.2 (default). The gateway and the device
must belong in the same subnet mask to be able to communicate with each other.
7.2 What You Can Do in the LAN IP Screen
Use the LAN IP screen to configure the IP address of your NWA (see Section 7.6 on page 90).
7.3 What You Need to Know
The Ethernet parameters of the NWA are preset in the factory with the following values:
1 IP address of 192.168.1.2
2 Subnet mask of 255.255.255.0 (24 bits)

- On aps without wmm qos all traffic streams are given the same access priority to the wireless network if the introduction of another traffic stream creates a data transmission demand that exceeds the current network capacity then the new traffic stream reduces the throughput of the other traffic streams 85
- Table 25 wmm qos priorities 85
- Term description 85
- The following table describes the wmm qos priority levels that the nwa uses 85
- The nwa uses wmm qos to prioritize traffic streams according to the ieee 802 q or dscp information in each packet s header the nwa automatically determines the priority to use for an individual traffic stream this prevents reductions in data transmission for applications that are sensitive to latency and jitter variations in delay 85

- Ppendi 161
- Subnet masks 162
- An ip address with host ids of all zeros is the ip address of the network 192 68 with a 24 bit subnet mask for example an ip address with host ids of all ones is the broadcast address for that network 192 68 55 with a 24 bit subnet mask for example 163
- Appendix c ip addresses and subnetting 163
- As these two ip addresses cannot be used for individual hosts calculate the maximum number of possible hosts in a network as follows 163
- Binary 163
- Decimal 1st octet 163
- For example 192 25 is equivalent to saying 192 with subnet mask 255 55 55 28 163
- Nd octet 163
- Network size 163
- Notation 163
- Nwa1000 series user s guide 163
- Rd octet 4th octet 163
- 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 this is usually specified by writing a followed by the number of bits in the mask after the address 163
- Subnet mask host id size maximum number of hosts 163
- Subnet masks are expressed in dotted decimal notation just like ip addresses the following examples show the binary and decimal notation for 8 bit 16 bit 24 bit and 29 bit subnet masks 163
- Subnet masks can be referred to by the size of the network number part the bits with a 1 value for example an 8 bit mask means that the first 8 bits of the mask are ones and the remaining 24 bits are zeroes 163
- Table 40 subnet masks 163
- Table 41 maximum host numbers 163
- The size of the network number determines the maximum number of possible hosts you can have on your network the larger the number of network number bits the smaller the number of remaining host id bits 163
- 2 or 254 possible hosts 164
- Appendix c ip addresses and subnetting 164
- Figure 87 subnetting example before subnetting 164
- In this example the company network address is 192 68 the first three octets of the address 192 68 are the network number and the remaining octet is the host id allowing a maximum of 164
- Last octet binary 164
- Last octet decimal 164
- Nwa1000 series user s guide 164
- Subnet mask alternative notation 164
- Subnetting 164
- Table 42 alternative subnet mask notation 164
- The borrowed host id bit can have a value of either 0 or 1 allowing two subnets 192 68 25 and 192 68 28 25 164
- The following figure shows the company network before subnetting 164
- The following table shows some possible subnet masks using both notations 164
- You can borrow one of the host id bits to divide the network 192 68 into two separate sub networks the subnet mask is now 25 bits 255 55 55 28 or 25 164
- You can use subnetting to divide one network into multiple sub networks in the following example a network administrator creates two sub networks to isolate a group of servers from the rest of the company network for security reasons 164
- Example four subnets 165
- Appendix c ip addresses and subnetting 166
- Example eight subnets 166
- Ip subnet mask network number last octet bit value 166
- Nwa1000 series user s guide 166
- Similarly use a 27 bit mask to create eight subnets 000 001 010 011 100 101 110 and 111 166

- Encryption 186
- For added security certificate based authentications eap tls eap ttls and peap use dynamic keys for data encryption they are often deployed in corporate environments but for public deployment a simple user name and password pair is more practical the following table is a comparison of the features of authentication types 186
- If both an ap and the wireless clients support wpa2 and you have an external radius server use wpa2 for stronger data encryption if you don t have an external radius server you should use wpa2 psk wpa2 pre shared key that only requires a single identical password entered into each access point wireless gateway and wireless client as long as the passwords match a wireless client will be granted access to a wlan 186
- Key differences between wpa2 and wep are improved data encryption and user authentication 186
- Nwa1000 series user s guide 186
- Select wep only when the ap and or wireless clients do not support wpa2 wep is less secure than wpa2 186
- Table 57 comparison of eap authentication types 186
- The radius server distributes a pairwise master key pmk key to the ap that then sets up a key hierarchy and management system using the pmk to dynamically generate unique data encryption keys to encrypt every data packet that is wirelessly communicated between the ap and the wireless clients this all happens in the background automatically 186
- Tkip uses 128 bit keys that are dynamically generated and distributed by the authentication server aes advanced encryption standard is a block cipher that uses a 256 bit mathematical algorithm called rijndael they both include a per packet key mixing function a message integrity check mic named michael an extended initialization vector iv with sequencing rules and a re keying mechanism 186
- Wpa2 ieee 802 1i is a wireless security standard that defines stronger encryption authentication and key management 186
- Wpa2 regularly change and rotate the encryption keys so that the same encryption key is never used twice 186
- Wpa2 uses tkip when required for compatibility reasons but offers stronger encryption than tkip with advanced encryption standard aes in the counter mode with cipher block chaining message authentication code protocol ccmp 186

- 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 189

- Table 58 wireless security relational matrix 189
- 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 189
