The reason is, those are Layer2 switchports.

You need to create a Vlan and associate those ports to the Vlan, for instance:

1) Create Layer 2 Vlan

Rack1SW1#vlan database

Rack1SW1(vlan)#Vlan 100

VLAN 100 added:

Name: VLAN0100


2) Create Layer 3 Vlan

Rack1SW1(config)#inter vlan 100

Rack1SW1(config-if)#ip add

3) Assign Vlan to the Port

Rack1SW1(config)#int f1/0

Rack1SW1(config-if)#switchport access vlan 100
