6 Click the Save link in the upper right corner of the web configurator to save your configuration
permanently.
7 The DHCP server can then assign a specific IP address based on the DHCP request.
6.3.4 Troubleshooting
Check the client A’s IP address. If it did not receive the IP address 172.16.1.18, make sure:
1 Client A is connected to the Switch’s port 2 in VLAN 102.
2 You configured the correct VLAN ID, port number and system name for DHCP relay on both the
DHCP server and the Switch.
3 You clicked the Save link on the Switch to have your settings take effect.

- 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 93

- 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 93
- Vlan port set up 93
- 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 93

- Port based vlan setup 97
- Port based vlans are specific only to the switch on which they were created 97
- Port based vlans are vlans where the packet forwarding decision is based on the destination mac address and its associated port 97
- 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 97

- 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
- You can set priority level to the voice vlan and add mac address of ip phones from specific manufacturers by using its id from the organizationally unique identifiers oui 100

- 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 233
- Gs1920 series user s guide 233
- 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 233
- 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 233
- 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 233
- 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 233
- Note the switch will drop all pppoe discovery packets if you enable the pppoe intermediate agent and there are no trusted ports 233
