Can VLAN use DHCP?
DHCP VLAN Relay can be applied in such scenario: a DHCP server is deployed to offer IP addresses to clients in multiple VLANs. These VLANs do not have VLAN interfaces. All the DHCP packets can be forwarded through this interface so that the clients can get IP addresses from the DHCP server.
How do I DHCP into a VLAN?
Packet tracer lab setup
- Create three VLANs and add 2 PCs to each VLAN.
- Configure the DHCP server on the switch and create three DHCP pools.
- Assign a DHCP pool to each VLAN.
- Configure all PCs as DHCP clients.
- Verify that all PCs receive their IP configuration from the DHCP server.
- Test connectivity between all PCs.
Do I need a DHCP server for each VLAN?
Each VLAN is a broadcast domain, so essentially you have to put a DHCP server on each VLAN.
How does DHCP superscope work?
Superscope allows a DHCP server to provide leases from more than one scope to clients on a single physical network. With this feature, a DHCP server can do the following: Support DHCP clients on a single physical network segment (such as a single Ethernet LAN segment) where multiple logical IP networks are used.
Does each VLAN need a DHCP server?
How do I program a VLAN on a Cisco switch?

How do I set up voice VLAN?
1. How to Configure Voice VLAN?
- Create a VLAN on the switch and add interfaces to the VLAN to implement Layer 2 interworking.
- Configure the OUI to match the source MAC address of the received packet.
- Configure the voice VLAN function on the interface.
What is Auto Voice VLAN?
Auto Voice VLAN is responsible to maintain the voice VLAN, but depends on Auto Smartport to maintain the voice VLAN port memberships. Auto Voice VLAN performs the following functions when it is in operation: • It discovers voice VLAN information in CDP advertisements from directly connected neighbor devices.
How to configure Voice VLAN in Cisco sg300?
In regular Cisco IOS switches, this task is configured as follows: Trying to achieve this scenario with a Cisco SG300 switch is turning into a nightmare. You have to deal with a Dynamic Voice VLAN set to the Auto Voice VLAN mode. Then, you have to have a trigger configured and Auto Smartport enabled.
How many VLANs does the Asus sg300-20 have?
The intent is to have two VLAN’s: VLAN 1: all devices, servers, etc. The SG300-20 is connected to an Asus RT-AC66U router on the 192.168.1.x subnet and provides internal network access and WiFi access (router IP address is 192.168.1.1 and is default gateway). All that works with no issues.
What is the IP address of the sg300-20 router?
The SG300-20 is connected to an Asus RT-AC66U router on the 192.168.1.x subnet and provides internal network access and WiFi access (router IP address is 192.168.1.1 and is default gateway). All that works with no issues. So my task is simply to create VLAN 2 on 192.168.2.x subnet and use DHCP to allocate addresses.
Is there a GUI administration guide for sg300?
The SG300 GUI Administration Guide is a disaster – it was written by someone who does not know proper English grammar, and it is impossible to understand. The CLI Administration Guide seems to be written better, but it does not have enough information on configuring voice VLANs.
