- Chapter 6 broadband 76
- Connection dsl link type mode encapsulation connection settings 76
- Encapsulation is used to include data from an upper layer protocol into a lower layer protocol to set up a wan connection to the internet you need to use the same encapsulation method used by your isp internet service provider if your isp offers a dial up internet connection using pppoe ppp over ethernet they should also provide a username and password and service name for user authentication 76
- Encapsulation method 76
- Layer 2 interface internet connection 76
- Table 6 wan setup overview 76
- The following terms and concepts may help as you read this chapter 76
- The wan ip address is an ip address for the device which makes it accessible from an outside network it is used by the device to communicate with other devices in other networks it can be static fixed or dynamically assigned by the isp each time the device tries to access the internet 76

- Note wep is extremely insecure its encryption can be broken by an attacker using widely available software it is strongly recommended that you use a more effective security mechanism use the strongest security mechanism that all the wireless devices in your network support for example use wpa psk or wpa2 psk if all your wireless devices support it or use wpa or wpa2 if your wireless devices support it and you have a radius server if your wireless devices support nothing stronger than wep use the highest encryption level available 106

- Ieee 802 p user priority ethernet priority 181
- If you enable qos on the device the device can automatically base on the ieee 802 p priority level ip precedence and or packet length to assign priority to traffic which does not match a class 181
- Ip precedence 181
- Layer 2 layer 3 181
- Priority queue 181
- Similar to ieee 802 p prioritization at layer 2 you can use ip precedence to prioritize packets in a layer 3 network ip precedence uses three bits of the eight bit tos type of service field in the ip header there are eight classes of services ranging from zero to seven in ip precedence zero is the lowest priority level and seven is the highest 181
- Table 53 internal layer2 and layer3 qos mapping 181
- The dscp value determines the forwarding behavior the phb per hop behavior that each packet gets across the diffserv network based on the marking rule different kinds of traffic can be marked for different kinds of forwarding resources can then be allocated according to the dscp values and the configured policies 181
- The following table shows you the internal layer 2 and layer 3 qos mapping on the device on the device traffic assigned to higher priority queues gets through faster while traffic in lower index queues is dropped if the network is congested 181

- Ip addresses and subnetting 339
- Ppendi 339
- Subnet masks 340
- 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 341
- Appendix c ip addresses and subnetting 341
- As these two ip addresses cannot be used for individual hosts calculate the maximum number of possible hosts in a network as follows 341
- Binary 341
- Decimal 1st octet 341
- For example 192 25 is equivalent to saying 192 with subnet mask 255 55 55 28 341
- Nd octet 341
- Network size 341
- Notation 341
- Rd octet 4th octet 341
- 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 341
- Subnet mask host id size maximum number of hosts 341
- 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 341
- 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 341
- Table 121 subnet masks 341
- Table 122 maximum host numbers 341
- 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 341
- Vmg1312 b10b vmg1312 b30b series user s guide 341
- 2 or 254 possible hosts 342
- Appendix c ip addresses and subnetting 342
- Figure 194 subnetting example before subnetting 342
- 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 342
- Last octet binary 342
- Last octet decimal 342
- Subnet mask alternative notation 342
- Subnetting 342
- Table 123 alternative subnet mask notation 342
- The borrowed host id bit can have a value of either 0 or 1 allowing two subnets 192 68 25 and 192 68 28 25 342
- The following figure shows the company network before subnetting 342
- The following table shows some possible subnet masks using both notations 342
- Vmg1312 b10b vmg1312 b30b series user s guide 342
- 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 25 342
- 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 342
- Example four subnets 343
- Appendix c ip addresses and subnetting 344
- Broadcast address 344
- Example eight subnets 344
- Ip subnet mask network number last octet bit value 344
- Similarly use a 27 bit mask to create eight subnets 000 001 010 011 100 101 110 and 111 344

- Eap ttls is an extension of the eap tls authentication that uses certificates for only the server side authentications to establish a secure connection client authentication is then done by sending username and password through the secure connection thus client identity is protected for client authentication eap ttls supports eap methods and legacy authentication methods such as pap chap ms chap and ms chap v2 364
- Eap ttls tunneled transport layer service 364
- 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 364
- 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 364
- Leap lightweight extensible authentication protocol is a cisco implementation of ieee 802 x 364
- Like eap ttls server side certificate authentication is used to establish a secure connection then use simple username and password methods through the secured connection to authenticate the clients thus hiding client identity however peap only supports eap methods such as eap md5 eap mschapv2 and eap gtc eap generic token card for client authentication eap gtc is implemented only by cisco 364
- Note eap md5 cannot be used with dynamic wep key exchange 364
- Peap protected eap 364
- Table 133 comparison of eap authentication types 364
- 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 364

- A radiation pattern is a diagram that allows you to visualize the shape of the antenna s coverage area 368
- 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 368
- An antenna in the frequency of 2 ghz ieee 802 1b and ieee 802 1g or 5ghz ieee 802 1a is needed to communicate efficiently in a wireless lan 368
- Antenna characteristics 368
- Antenna gain 368
- Antenna gain measured in db decibel is the increase in coverage within the rf beam width higher antenna gain improves the range of the signal for better communications 368
