Cisco与H3C链路聚合对接
Cisco 的channel-group mode有两大类：
1、channel-group mode on
强制开启链路聚合
2、channel-group mode active
启用LACP协议
故与H3C做对接时，有以下两种情况：
一、静态（不启用LACP协议）
Cisco:
#
interface Port-channel1
switchport trunk encapsulation dot1q
switchport mode trunk
#
interface FastEthernet0/21
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode on
#
interface FastEthernet0/22
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode on
#
------------------------------------------------------
H3C:
#
interface Bridge-Aggregation 1
port link-type trunk
port trunk permit vlan all
#
interface GigabitEthernet1/0/21
port link-type trunk
port trunk permit vlan all
port link-aggregation group 1
#
interface GigabitEthernet1/0/22
port link-type trunk
port trunk permit vlan all
port link-aggregation group 1
#
二、动态（启用LACP协议）
Cisco:
#
interface Port-channel1
switchport trunk encapsulation dot1q
switchport mode trunk
#
interface FastEthernet0/21
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode active
#
interface FastEthernet0/22
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode active
#
------------------------------------------------------
H3C:
#
interface Bridge-Aggregation1
port link-type trunk
port trunk permit vlan all
link-aggregation mode dynamic
#
interface Ethernet1/0/8
port link-aggregation group 1
#
interface Ethernet1/0/9
port link-aggregation group 1
