[SW2]int g0/0/2
[SW2-GigabitEthernet0/0/2]port link-type access 
[SW2-GigabitEthernet0/0/2]port default vlan 10
[SW2-GigabitEthernet0/0/2]int g0/0/3	
[SW2-GigabitEthernet0/0/3]port link-type access 
[SW2-GigabitEthernet0/0/3]port default vlan 20
[SW2-GigabitEthernet0/0/3]int g0/0/1	
[SW2-GigabitEthernet0/0/1]port link-type trunk 	
[SW2-GigabitEthernet0/0/1]port trunk allow-pass vlan all

  • SW3

    [SW3]vlan batch 30 40
