- A vlan virtual local area network allows a physical network to be partitioned into multiple logical networks devices on a logical network belong to one group a device can belong to more than one group with vlan a device cannot directly talk to or hear from devices that are not in the same group s the traffic must first go through a router 77
- Click basic setting and then switch setup in the navigation panel to display the screen as shown the vlan setup screens change depending on whether you choose 802 q or port based in the vlan type field in this screen refer to the chapter on vlan 77
- In mtu multi tenant unit applications vlan is vital in providing isolation and security among the subscribers when properly configured vlan prevents one subscriber from accessing the network resources of another on the same lan thus a user will not see the printers and hard disks of another user in the same building 77

- Garp and gvrp are the protocols used to automatically register vlan membership across switches 86
- Garp generic attribute registration protocol allows network switches to register and de register attribute values with other garp participants within a bridged lan garp is a protocol that provides a generic mechanism for protocols that serve a more specific application for example gvrp 86
- Garp timers 86
- Gvrp garp vlan registration protocol is a registration protocol that defines a way for switches to register necessary vlan members on ports across the network enable this function to permit vlan groups beyond the local switch 86
- Please refer to the following table for common ieee 802 q vlan terminology 86
- Switches join vlans by making a declaration a declaration is made by issuing a join message using garp declarations are withdrawn by issuing a leave message a leave all message terminates all registrations garp timers set declaration timeout values 86

- For example an isp internet services provider may divide different types of services it provides to customers into different ip subnets traffic for voice services is designated for ip subnet 172 6 24 video for 192 68 24 and data for 10 24 the switch can then be configured to group incoming traffic based on the source ip subnet of incoming frames 92
- Internet 92
- Subnet based vlans 92
- Subnet based vlans allow you to group traffic into logical vlans based on the source ip subnet you specify when a frame is received on a port the switch checks if a tag is added already and the ip subnet it came from the untagged packets from the same ip subnet are then placed in the same subnet based vlan one advantage of using subnet based vlans is that priority can be assigned to traffic from the same ip subnet 92
- Vlan port setting continued 92
- You configure a subnet based vlan with priority 6 and vid of 100 for traffic received from ip subnet 172 6 24 voice services you also have a subnet based vlan with priority 5 and vid of 200 for traffic received from ip subnet 192 68 24 video services lastly you configure vlan with priority 3 and vid of 300 for traffic received from ip subnet 10 24 data services all untagged incoming frames will be classified based on their source ip subnet and prioritized accordingly that is video services receive the highest priority and data the lowest 92

- Spanning tree protocol 107
- Stp rstp overview 107
- Stp terminology 107
- 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 108
- Chapter 11 spanning tree protocol 108
- Es 3148 user s guide 108
- For each lan segment a designated bridge is selected this bridge has the lowest cost to the root among the bridges connected to the lan 108
- How stp works 108
- On each bridge the root port is the port through which this bridge communicates with the root it is the port on this switch with the lowest path cost to the root the root path cost if there is no root port then this switch has been accepted as the root bridge of the spanning tree network 108
- Once a stable network topology has been established all bridges listen for hello bpdus bridge protocol data units transmitted from the root bridge if a bridge does not get a hello bpdu after a predefined interval max age the bridge assumes that the link to the root bridge is down this bridge then initiates negotiations with other bridges to reconfigure the network to re establish a valid network topology 108
- Path cost is the cost of transmitting a frame onto a lan through that port the recommended cost is assigned according to the speed of the link to which a port is attached the slower the media the higher the cost 108
- Stp aware switches exchange bridge protocol data units bpdus periodically when the bridged lan topology changes a new spanning tree is constructed 108

- Igmp filtering profile 177
- In mvr a source port is a port on the switch that can send and receive multicast traffic in a multicast vlan while a receiver port can only receive multicast traffic once configured the switch maintains a forwarding table that matches the multicast stream to the associated multicast group 177
- Multicast vlan registration mvr is designed for applications such as media on demand mod that use multicast traffic across an ethernet ring based service provider network 177
- Mvr allows one single multicast vlan to be shared among different subscriber vlans on the network while isolated in different subscriber vlans connected devices can subscribe to and unsubscribe from the multicast stream in the multicast vlan this improves bandwidth utilization with reduced multicast traffic in the subscriber vlans and simplifies multicast group management 177
- Mvr only responds to igmp join and leave control messages from multicast groups that are configured under mvr join and leave reports from other multicast groups are managed by igmp snooping 177

- Green low loss priority level packets are forwarded 227
- In color aware mode the evaluation of the packets uses the existing packet loss priority trtcm can increase a packet loss priority of a packet but it cannot decrease it packets that have been previously marked red or yellow can only be marked with an equal or higher packet loss priority 227
- Packets marked red high packet loss priority continue to be red without evaluation against the pir or cir packets marked yellow can only be marked red or remain yellow so they are only evaluated against the pir only the packets marked green are first evaluated against the pir and then if they don t exceed the pir level are they evaluated against the cir 227

- Trtcm color blind mode 227
- Trtcm operates in one of two modes color blind or color aware in color blind mode packets are marked based on evaluating against the pir and cir regardless of if they have previously been marked or not in the color aware mode packets are marked based on both existing color and evaluation against the pir and cir if the packets do not match any of colors then the packets proceed unchanged 227

- Ip addresses and subnetting 325
- Ppendix 325
- Structure 325
- A subnet mask has 32 bits if a bit in the subnet mask is a 1 then the corresponding bit in the ip address is part of the network number if a bit in the subnet mask is 0 then the corresponding bit in the ip address is part of the host id 326
- A subnet mask is used to determine which bits are part of the network number and which bits are part of the host id using a logical and operation the term subnet is short for sub network 326
- Appendix c ip addresses and subnetting 326
- 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 326
- Es 3148 user s guide 326
- Figure 207 network number and host id 326
- How much of the ip address is the network number and how much is the host id varies according to the subnet mask 326
- Subnet masks 326
- 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 326
- Table 124 ip address network number and host id example 326
- The following example shows a subnet mask identifying the network number in bold text and host id of an ip address 192 68 in decimal 326
- 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 327
- Appendix c ip addresses and subnetting 327
- As these two ip addresses cannot be used for individual hosts calculate the maximum number of possible hosts in a network as follows 327
- Es 3148 user s guide 327
- For example 192 25 is equivalent to saying 192 with subnet mask 255 55 55 28 327
- Network size 327
- Notation 327
- 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 327
- 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 327
- Table 125 subnet masks 327
- Table 126 maximum host numbers 327
- Table 127 alternative subnet mask notation 327
- The following table shows some possible subnet masks using both notations 327
- 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 327
- 2 or 254 possible hosts 328
- Appendix c ip addresses and subnetting 328
- Es 3148 user s guide 328
- Figure 208 subnetting example before subnetting 328
- 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 328
- Subnetting 328
- Table 127 alternative subnet mask notation continued 328
- The borrowed host id bit can have a value of either 0 or 1 allowing two subnets 192 68 25 and 192 68 28 25 328
- The following figure shows the company network after subnetting there are now two sub networks a and b 328
- The following figure shows the company network before subnetting 328
- 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 25 328
- 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 328
- Example four subnets 329
- Appendix c ip addresses and subnetting 330
- Es 3148 user s guide 330
- Example eight subnets 330
- Similarly use a 27 bit mask to create eight subnets 000 001 010 011 100 101 110 and 111 330
