huawei和cisco交换机汇聚端口互联

手工模式

Cisco2950配置：

interface Port-channel1

interface FastEthernet0/1

channel-group 1 mode on

interface FastEthernet0/2

channel-group 1 mode on

Huawei S3352配置：

int eth-trunk 1

int ether 0/0/47

undo port default vlan

undo port link

bpdu disable

undo ndp enable

undo ntdp enable

eth-trunk 1

int ether 0/0/48

undo port default vlan

undo port link

bpdu disable

undo ndp enable

undo ntdp enable

eth-trunk 1

注意：在先配置cisco交换机，再配置huawei交换机时，华为交换机的e0/0/47口上会有突发流量，出入方向差不多。reset counter 之后应该会恢复正常。

采用LACP互联

cisco2950上的配置：

int port-channel 1

interface FastEthernet0/1

channel-group 1 mode active //passive模式下也可以

channel-protocol lacp

interface FastEthernet0/2

channel-group 1 mode active //passive模式下也可以

channel-protocol lacp

华为S3352上的配置：

[Quidway]lacp priority 100 //不配置保持默认也可以

interface Eth-Trunk0

mode lacp-static

bpdu enable //LACP通过BPDU来通信，所以一定要开启BPDU

int ether 0/0/47

eth-trunk 0

int ether 0/0/48

eth-trunk 0
