This window appears when you choose Administration > IP Addresses on the menu bar. You can also click here to launch it. Use it to assign network addresses to VLANs and, for Catalyst 3550 switches, to create SVIs (switched virtual interfaces) and routed ports.
Begin by selecting the device from the Host Name list. Then use these tabs:
When you are done, click OK.
In the Interface Name column, you see the names of the VLANs and, for Catalyst 3550 switches, the names of ports. To assign an IP address and subnet mask to a VLAN or to a port or to modify an address and mask:
If a non-3550 switch has more than one VLAN with an IP address, only one at a time can be active. Use the Management VLAN window to specify the active VLAN.
To create an SVI on a Catalyst 3550 switch:
To create a routed port on a Catalyst 3550 switch:
Creating an SVI or a routed port does not enable routing on the device. To do that you must choose Device > IP Routing > Protocols and use the IP Routing Protocols window. This window is available only if you have a Catalyst 3550 switch in the cluster.
