一台华三交换机分别连接三台交换机,它们之间连接均采用链路聚合方式,请问怎样为交换机分别设置链路聚合?

最佳答案
· Device A与Device B通过各自的二层以太网接口GigabitEthernet1/0/1~GigabitEthernet1/0/3相互连接。
· 在Device A和Device B上分别配置二层静态链路聚合组,并实现设备间VLAN 10和VLAN 20分别互通。
图1-7 二层静态聚合配置组网图
(1) 配置Device A
# 创建VLAN 10,并将端口GigabitEthernet1/0/4加入到该VLAN中。
<DeviceA> system-view
[DeviceA] vlan 10
[DeviceA-vlan10] port gigabitethernet 1/0/4
[DeviceA-vlan10] quit
# 创建VLAN 20,并将端口GigabitEthernet1/0/5加入到该VLAN中。
[DeviceA] vlan 20
[DeviceA-vlan20] port gigabitethernet 1/0/5
[DeviceA-vlan20] quit
# 创建二层聚合接口1。
[DeviceA] interface bridge-aggregation 1
[DeviceA-Bridge-Aggregation1] quit
# 分别将端口GigabitEthernet1/0/1至GigabitEthernet1/0/3加入到聚合组1中。
[DeviceA] interface gigabitethernet 1/0/1
[DeviceA-GigabitEthernet1/0/1] port link-aggregation group 1
[DeviceA-GigabitEthernet1/0/1] quit
[DeviceA] interface gigabitethernet 1/0/2
[DeviceA-GigabitEthernet1/0/2] port link-aggregation group 1
[DeviceA-GigabitEthernet1/0/2] quit
[DeviceA] interface gigabitethernet 1/0/3
[DeviceA-GigabitEthernet1/0/3] port link-aggregation group 1
[DeviceA-GigabitEthernet1/0/3] quit
# 配置二层聚合接口1为Trunk端口,并允许VLAN 10和20的报文通过。
[DeviceA] interface bridge-aggregation 1
[DeviceA-Bridge-Aggregation1] port link-type trunk
[DeviceA-Bridge-Aggregation1] port trunk permit vlan 10 20
[DeviceA-Bridge-Aggregation1] quit
(2) 配置Device B
Device B的配置与Device A相似,配置过程略。
# 查看Device A上所有聚合组的详细信息。
[DeviceA] display link-aggregation verbose
Loadsharing Type: Shar -- Loadsharing, NonS -- Non-Loadsharing
Port Status: S -- Selected, U -- Unselected, I -- Individual
Port: A -- Auto port, M -- Management port, R -- Reference port
Flags: A -- LACP_Activity, B -- LACP_Timeout, C -- Aggregation,
D -- Synchronization, E -- Collecting, F -- Distributing,
G -- Defaulted, H -- Expired
Aggregate Interface: Bridge-Aggregation1
Aggregation Mode: Static
Loadsharing Type: Shar
Management VLANs: None
Port Status Priority Oper-Key
GE1/0/1(R) S 32768 1
GE1/0/2 S 32768 1
GE1/0/3 S 32768 1
以上信息表明,聚合组1为负载分担类型的二层静态聚合组,包含有三个选中端口。

步骤如下:
1、创建聚合接口
[H3C]interface bridge-aggregation 1
如果是动态聚合方式还需添加命令
[H3C-Bridge-Aggregation1] link-aggregation mode dynamic
2、接口加入聚合组
[H3C]interface gigabitethernet 1/0/3
[H3C-GigabitEthernet1/0/3] port link-aggregation group 1
注意:
1、需要聚合在一起的端口加入一个聚合组
2、聚合之前接口下为空配置(否则可能导致聚合不成功),加入聚合组后,属性在聚合接口下配置,配置会同步到所有绑定的物理口
3、动态聚合方式需要对端也配成动态聚合,否则聚合不成功

主交换机需配置三个链路聚合,以上讲的太简了,请详细讲一个步骤可以吗?
您好,请知:
以下是链路聚合的配置要点,请参考:
<H3C>sys
[H3C]sysname SW1
[SW1]vlan 10
[SW1-vlan10]quit
[SW1]int gi 1/0/3
[SW1-GigabitEthernet1/0/3]port link-type access
[SW1-GigabitEthernet1/0/3]port access vlan 10
[SW1-GigabitEthernet1/0/3]description <connect to PC>
[SW1-GigabitEthernet1/0/3]quit
[SW1]int Bridge-Aggregation 1 //创建链路聚合组1
[SW1-Bridge-Aggregation1]quit
[SW1]int range gi 1/0/1 to gi 1/0/2
[SW1-if-range]port link-aggregation group 1 //将链路聚合组应用到接口
[SW1-if-range]quit
[SW1]int Bridge-Aggregation 1 //继续配置链路聚合组1
[SW1-Bridge-Aggregation1]port link-type trunk
Configuring GigabitEthernet1/0/1 done.
Configuring GigabitEthernet1/0/2 done.
[SW1-Bridge-Aggregation1]undo port trunk permit vlan 1
Configuring GigabitEthernet1/0/1 done.
Configuring GigabitEthernet1/0/2 done.
[SW1-Bridge-Aggregation1]port trunk permit vlan 10
Configuring GigabitEthernet1/0/1 done.
Configuring GigabitEthernet1/0/2 done.
[SW1-Bridge-Aggregation1]quit
