- 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 62

- On the switch an ip address is not bound to any physical ports since each ip address on the switch must be in a separate subnet the configured ip address is also known as ip interface or routing domain in addition this allows routing between subnets based on the ip address without additional routers 67
- The switch needs an ip address for it to be managed over the network the factory default ip address is 192 68 the subnet mask specifies the network number portion of an ip address the factory default subnet mask is 255 55 55 67

- Enable vlan trunking on a port to allow frames belonging to unknown vlan groups to pass through that port this is useful if you want to set up vlan groups on end devices without having to configure the same vlan groups on intermediary devices 88
- Figure 60 port vlan trunking 88
- 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 88
- Please refer to the following table for common ieee 802 q vlan terminology 88
- Port vlan trunking 88
- Refer to the following figure suppose you want to create vlan groups 1 and 2 v1 and v2 on devices a and b without vlan trunking you must configure vlan groups 1 and 2 on all intermediary switches c d and e otherwise they will drop frames with unknown vlan group tags however with vlan trunking enabled on a port s in each intermediary switch you only need to create vlan groups in the end devices a and b c d and e automatically allow frames with vlan group tags 1 and 2 vlan groups that are unknown to those switches to pass through their vlan trunking port s 88

- 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 96
- Label description 96
- Subnet based vlans 96
- 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 96
- Vlan port setup 96
- Xs1920 series user s guide 96
- 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 96

- Voice vlan ensures that the sound quality of an ip phone is preserved from deteriorating when the data traffic on the switch ports is high it groups the voice traffic with defined priority into an assigned vlan which enables the separation of voice and data traffic coming onto the switch port 100

- Port based vlan setup 103
- Port based vlans are specific only to the switch on which they were created 103
- Port based vlans are vlans where the packet forwarding decision is based on the destination mac address and its associated port 103
- Port based vlans require allowed outgoing ports to be defined for each port therefore if you wish to allow two subscriber ports to talk to each other for example between conference rooms in a hotel you must define the egress an egress port is an outgoing port that is a port through which a data packet leaves for both ports 103

- Every port is either a trusted port or an untrusted port for the pppoe intermediate agent this setting is independent of the trusted untrusted setting for dhcp snooping or arp inspection you can also specify the agent sub options circuit id and remote id that the switch adds to padi and padr packets from pppoe clients 245
- If a padi or padr packet is sent from a pppoe client but received on a trusted port the switch forwards it to other trusted port s 245
- If a padi padr or padt packet is sent from a pppoe client and received on an untrusted port the switch adds a vendor specific tag to the packet and then forwards it to the trusted port s 245
- If a pado pppoe active discovery offer pads pppoe active discovery session confirmation or padt pppoe active discovery terminate packet is sent from a pppoe server and received on a trusted port the switch forwards it to all other ports 245
- Intermediate agent screen the switch automatically generates a circuit id string according to the default circuit id syntax which is defined in the dsl forum working text wt 101 the default access node identifier is the host name of the pppoe intermediate agent and the eth indicates ethernet 245
- Note the switch will drop all pppoe discovery packets if you enable the pppoe intermediate agent and there are no trusted ports 245
