SW#1 컨피그
1. 2개의 VLAN 생성 (생략가능)
SW1(config)#vlan 100
SW1(config-vlan)#name COMPUTER
SW1(config-vlan)#exit
SW1(config)#vlan 101
SW1(config-vlan)#name VOIP
SW1(config-vlan)#exit
2. 인터페이스 구성
SW1(config)#interface GigabitEthernet 0/1
SW1(config-if)#switchport mode access
SW1(config-if)#switchport access vlan 100
SW1(config-if)#switchport voice vlan 101
SW1(config-if)# spanning-tree portfast
SW1(config-if)#exit
3. 확인
