Can DHCP assign VLAN ID?
VLAN ID has nothing to do with how DHCP determines which subnet to assign addresses from. DHCP uses the ip address of the BOOTP/DHCP relay agent to determine which subnet to assign ip addresses from.
How does DHCP know which VLAN?
The DHCP server will use the source IP address on the request to determine the appropriate scope to use for assigning the address. VLAN is the answer here. The easiest thing to do would be to have individual NICs for each VLAN subnet and bind the DHCP server IP ranges to their respective NIC.
How do I assign a DHCP to 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.
What is DHCP VLAN?
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. …
What is apipa in Packet Tracer?

Does VLAN have IP address?
VLANs do not really have IP addresses assigned to them. They have a network assigned to them, or a subnet, or a network range, however you want to refer to it. The address the OP supplied us is an assignable address within the range of 192.168.
Where does the DHCP server see the vlan ip?
Broadcasts don’t cross VLANs. The relay agent receives it and unicasts it to the DHCP server you defined. The DHCP server sees the request coming in from the VLAN IP for VLAN 30, 192.168.30.1 in your case which is stored in the GIADDR field.
What is DHCP vendor specific option 43 for Phine?

What is DHCP assignment mode in virtual controller?
Based on the IP address range and client count configuration, the DHCP server in the Virtual Controller controls a scope that is a subset of the complete IP Address range for the subnet distributed across all the branches. This DHCP Assignment mode is used with the L2 forwarding mode.
How is the VLAN ID defined in 802.1Q?
802.1Q VLAN tags have a three bit field defined in IEEE 802.1p, the VoIP equipment can use to indicate the priority of sent frames. See Quality of Service. However, the same can be accomplished when using 802.1Q VLAN tags with VLAN ID = 0, which is mapped to the port VLAN ID at the next-hop adjacent Layer 2 switch.
