Static Virtual LANs (VLANs)
Special VLAN Types
Using DHCP to Obtain an IP Address
You can use DHCP to obtain an IPv4 address for your Management VLAN or a client on that VLAN. The following examples illustrate when an IP address will be received from the DHCP server.
1.If Blue_VLAN is configured as the Management VLAN and the DHCP server is also on Blue_VLAN, Blue_VLAN receives an IP address. Because DHCP Relay does not forward onto or off of the Management VLAN, devices on Red_VLAN cannot get an IP address from the DHCP server on Blue_VLAN (Management VLAN) and Red_VLAN does not receive an IP address.
