22.1 Layer 3 Management Interface
22.1.1 Introduction to Layer 3 Management Interface
Only one layer 3 management interface can be created on switch. The Layer 3 interface is not
a physical interface but a virtual interface. Layer 3 interface is built on VLANs. The Layer 3
interface can contain one or more layer 2 ports which belong to the same VLAN, or contain no
layer 2 ports. At least one of the Layer 2 ports contained in Layer 3 interface should be in UP
state for Layer 3 interface in UP state, otherwise, Layer 3 interface will be in DOWN state. The
switch can use the IP addresses set in the layer 3 management interface to communicate with
the other devices via IP.
