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 trac between the ports in dierent VLANs route using the IP address. Congure the L3 VLAN interface to remain administratively UP
or DOWN using the shutdown and no shutdown commands. This provisioning only aects the L3 trac across the members of a
VLAN and does not aect the L2 trac.
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 trac.
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
