Em đã gán Ip và subnet mask cho 4 vlan:
vlan 1 192.168.1.1 255.255.255.0
vlan 2 192.168.2.1 255.255.255.0
vlan 3 192.168.3.1 255.255.255.0
vlan 4 192.168.4.1 255.255.255.0
Sau khi gán xong đã ghi bằng lệnh write mem đã báo ok nhưng khi gõ lệnh show run thì vẫn báo là zero:
Current configuration : 1966 bytes
!
version 12.1
no service pad
service timestamps debug uptime
service timestamps log uptime
no service password-encryption
!
hostname Switch
!
!
ip subnet-zero
!
!
spanning-tree mode pvst
no spanning-tree optimize bpdu transmission
spanning-tree extend system-id
!
!
!
!
interface FastEthernet0/1
