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. See figure 2-32.
