Assign an IP Address to a VLAN
Assign an IP address to a VLAN so that it supports routing operations.
Before you begin
-
You must create the VLAN.
-
Activate IP forwarding globally.
-
If you use this procedure to create a Secondary IP Interface, you must first create the primary IP address.
About this task
If an IP interface is configured without specifying the VRF instance, it maps to VRF 0 by default.
Procedure
Example
Add a primary IP address to the VLAN and configure it as the DvR-One-IP interface. Give the address a name.
Switch:1>enable Switch:1#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Switch:1(config)#interface vlan 2 Switch:1(config-if)#ip address 192.0.2.5 255.255.255.0 dvr-one-ip name Boston
Variable Definitions
The following table defines parameters for the ip address command.
Variable |
Value |
---|---|
<A.B.C.D/X>|<A.B.C.D> <A.B.C.D> |
Specifies the IP address and subnet mask in the format A.B.C.D/X or A.B.C.D A.B.C.D. |
dvr-one-ip |
Specifies that the IP address will be used as the DvR gateway IP address and will be used by all other DvR Controllers for the DvR VLAN subnet. |
name WORD <0-64> |
Specifies the name associated with the IP address on a VLAN. |
secondary |
Identifies the IP address as a Secondary IP Interface. |
state-disabled |
Creates the IP interface in an administratively disabled state. This parameter is useful if you want to preconfigure an IP interface, including the routing protocol configuration for that interface, and enable it later during a maintenance window. This parameter applies only to the primary IP address. By default, the switch enables an IP interface after you configure the primary IP address. Note: This parameter
is not saved in the configuration file.
