You can assign IP information to your switch by using these methods:

The Express Setup program, as described in the switch getting started guide.

The CLI-based setup program, as described in the switch hardware installation guide.

The DHCP-based autoconfiguration, as described in the switch software configuration guide.

Manually assigning an IP address, as described in the switch software configuration guide.

If you are upgrading a Catalyst 3750 or a 2950 switch running Cisco IOS Release 12.1(11)AX, which 
uses the IEEE 802.1x feature, you must re-enable IEEE 802.1x after upgrading the software. For more

When upgrading or downgrading from Cisco IOS Release 12.2(18)SE, you might need to reconfigure 
the switch with the same password that you were using when running Cisco IOS Release 12.2(18)SE. 
This problem only occurs when changing from Cisco IOS Release 12.2(18)SE to any other release.
