网络工程 - 解决 Native Vlan Mismatch 错误 - 吾爱随笔录

我是 VLAN 的新手，我目前正在尝试完成此拓扑，但是我可以在所有三个交换机上看到以下错误：EX：

%CDP-4-NATIVE_VLAN_MISMATCH: Native VLAN mismatch discovered on FastEthernet0/2 (1), with S3 FastEthernet0/2 (99).

%CDP-4-NATIVE_VLAN_MISMATCH: Native VLAN mismatch discovered on FastEthernet0/1 (1), with S2 FastEthernet0/1 (99).

使用的配置是：S2：

int fa0/1
switchport mode trunk
switchport trunk native vlan 99
 int range fa0/1-5
switchport mode access
switchport access vlan 99
no shutdown
exit
int range fa0/6-10
switchport mode access
switchport access vlan 30
no shutdown
exit
int range fa0/11-17
switchport mode access
switchport access vlan 10
no shutdown
exit
int range fa0/18-24
switchport mode access
switchport access vlan 20
no shutdown
exit

S1：

int range fa0/1-2
switchport mode trunk
switchport trunk native vlan 99

S3：

int fa0/2
switchport mode trunk
switchport trunk native vlan 99
int range fa0/1-5
switchport mode access
switchport access vlan 99
no shutdown
exit
int range fa0/6-10
switchport mode access
switchport access vlan 30
no shutdown
exit
int range fa0/11-17
switchport mode access
switchport access vlan 10
no shutdown
exit
int range fa0/18-24
switchport mode access
switchport access vlan 20
no shutdown
exit

在所有交换机上创建的 vlan 是：

vlan 99
name management
vlan 30
name Guest(Default)
vlan 10
name Faculty/Staff
vlan 20
name Students

谁能帮我知道可能的错误是什么？
