Chapter 6 wireless lan 89
Nwa1120 series user s guide 89
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 89
Table 24 additional wireless terms 89
Term description 89
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 89
Wmm qos 89
Wmm qos prioritizes wireless traffic according to the delivery requirements of the individual and applications wmm qos is a part of the ieee 802 1e qos enhancement to certified wi fi wireless networks 89
Wmm wi fi multimedia qos quality of service ensures quality of service in wireless networks it controls wlan transmission priority on packets to be transmitted over the wireless network 89

Ip addresses and subnetting 169
Ppendi 169
Subnet masks 170
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 171
Appendix c ip addresses and subnetting 171
As these two ip addresses cannot be used for individual hosts calculate the maximum number of possible hosts in a network as follows 171
Binary 171
Decimal 1st octet 171
For example 192 25 is equivalent to saying 192 with subnet mask 255 55 55 28 171
Nd octet 171
Network size 171
Notation 171
Nwa1120 series user s guide 171
Rd octet 4th octet 171
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 171
Subnet mask host id size maximum number of hosts 171
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 171
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 171
Table 40 subnet masks 171
Table 41 maximum host numbers 171
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 171
2 or 254 possible hosts 172
Appendix c ip addresses and subnetting 172
Figure 89 subnetting example before subnetting 172
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 172
Last octet binary 172
Last octet decimal 172

Subnet mask alternative notation 172
Subnetting 172
Table 42 alternative subnet mask notation 172
The borrowed host id bit can have a value of either 0 or 1 allowing two subnets 192 68 25 and 192 68 28 25 172
The following figure shows the company network before subnetting 172
The following table shows some possible subnet masks using both notations 172
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 25 172
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 172
Example four subnets 173

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 195
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 195
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 195
If this feature is enabled it is not necessary to configure a default encryption key in the wireless security configuration screen you may still configure and store keys but they will not be used while dynamic wep is enabled 195
Key differences between wpa or wpa2 and wep are improved data encryption and user authentication 195
Leap lightweight extensible authentication protocol is a cisco implementation of ieee 802 x 195
Note eap md5 cannot be used with dynamic wep key exchange 195
Nwa1120 series user s guide 195
Select wep only when the ap and or wireless clients do not support wpa or wpa2 wep is less secure than wpa or wpa2 195
