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 trac between the ports in dierent VLANs route using the IP address. Congure the L3 VLAN interface to remain administratively UP
or DOWN using the shutdown and no shutdown commands. This provisioning only aects the L3 trac across the members of a
VLAN and does not aect the L2 trac.
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 trac.
1 Create a VLAN in CONFIGURATION mode (1 to 4094).
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 (up to eight secondary IP addresses).
Assign IP address to VLAN
OS10(config)# interface vlan 200
OS10(conf-if-vl-200)# ip address 10.1.15.1/8
