Assign IP address

You can assign an IP address to each VLAN to make it a L3 VLAN — the ports in that VLAN belong to that particular IP subnet.

The traffic between the ports in different VLANs route using the IP address. Configure the L3 VLAN interface to remain administratively UP or DOWN using the shutdown and no shutdown commands. This provisioning only affects the L3 traffic across the members of a VLAN and does not affect the L2 traffic.

You cannot assign an IP address to the default VLAN (VLAN 1). You can place VLANs and other logical interfaces in L3 mode to receive and send routed traffic.

  1. Create a VLAN in CONFIGURATION mode (1 to 4093).
    interface vlan 
                                           vlan-id
                                        
  2. Assign an IP address and mask to the VLAN in INTERFACE-VLAN mode.
    ip address 
                                           ip-address/prefix-length [secondary]
                                        
    • ip-address/prefix—length — Enter the IP address in dotted-decimal format (A.B.C.D/x).
    • secondary — Enter the interface backup IP address.

Assign IP address to VLAN

OS10(config)# interface vlan 200
                                 OS10(conf-if-vl-200)# ip address 10.1.15.1/8
