Static Virtual LANs (VLANs)

Special VLAN Types

4.If Red_VLAN is configured as the Management VLAN and the client is on Red_VLAN, but the DHCP server is on Blue_VLAN, the client will not receive an IP address. See figure 2-35.

Red_VLAN

Blue_VLAN

Red_VLAN is the Management VLAN and the client is on Red_VLAN. The DHCP server is on Blue_VLAN.

The client does not receive an IP address.
