思科交换机和华为交换机VLAN1通信异常，相信很多朋友都遇到过，毕竟在项目中遇到混搭的设备还是很多的，当遇到如下的问题的时候，如何合理的解决，
思朋CCIE给您提供一个合理的解决方案，还不赶快收藏！
问题：
有一台5300，用一个光口与思科的6509一个光口做trunk，两个光口都打成了trunk
5300的vlan 1作为管理地址。但是就是ping不通6509上的vlan 1的地址。
Cisco 交换机配置
show run int g1/0/12
Building configuration...
Current configuration : 134 bytes
!
interface GigabitEthernet1/0/12
switchport trunk encapsulation dot1q
switchport mode trunk
no ip address
speed nonegotiate
end
问题在华为交换机配置上
1华为交换机初始配置
[Quidway-GigabitEthernet0/1/1]dis this # interface GigabitEthernet0/1/1 port default vlan 1 bpdu enable ntdp enable ndp enable # return -- ------------------------------------------------------------------- [Quidway-GigabitEthernet0/1/1]port link-type trunk Error: Link-type trunk conflicts with default VLAN attribute on a port.
2建立trunk必须删除原来默认VLAN 1
[Quidway-GigabitEthernet0/1/1]undo port default vlan Oct 1 2008 01:26:42 Quidway %%01IFNET/4/IF_STATE(l): Interface Vlanif1 has turn ed into DOWN state. [Quidway-GigabitEthernet0/1/1] Oct 1 2008 01:26:42 Quidway %%01IFNET/4/LINK_STATE(l): Line protocol on interfa ce Vlanif1 has turned into DOWN state.
---------------------------------------------------- Quidway-GigabitEthernet0/1/1]dis this # interface GigabitEthernet0/1/1 bpdu enable ntdp enable ndp enable ----------------------------------------------------------
3 建立trunk
return [Quidway-GigabitEthernet0/1/1] Quidway-GigabitEthernet0/1/1]port link-type trunk Quidway-GigabitEthernet0/1/1]port trunk allow-pass vlan all --------------------- [Quidway-GigabitEthernet0/1/1]dis this # interface GigabitEthernet0/1/1 port link-type trunk port trunk allow-pass vlan 1 to 4094 bpdu enable ntdp enable ndp enable # return -------------------------------- ping 对端思科vlan 1 地址不通
[Quidway-GigabitEthernet0/1/1]ping 192.168.0.52 PING 192.168.0.52: 56 data bytes, press CTRL_C to break Request time out Request time out Request time out Request time out Request time out --- 192.168.0.52 ping statistics --- 5 packet(s) transmitted 0 packet(s) received 100.00% packet loss
-----------------------------------------
4 必须删除原来接口trunk，否则无法设置默认vlan 即思科所谓native vlan
[Quidway-GigabitEthernet0/1/1]undo port link-type
---------------------------------------------
5 把刚才删除默认VLAN1 恢复
[Quidway-GigabitEthernet0/1/1]port default vlan 1
[Quidway-GigabitEthernet0/1/1]dis this
#
interface GigabitEthernet0/1/1
port default vlan 1
port trunk allow-pass vlan 1 to 4094
bpdu enable
ntdp enable
ndp enable
#
Return
Return
ping 对端思科vlan 1 地址 OK
