Cisco交换机配置
1. 创建二层聚合接口
bash
interface port-channel 100
no shutdown
2. 将物理端口加入聚合组, 使用lacp主动模式
bash
interface G1/0/47
no shutdown
channel-group 100 mode active
exit
interface G1/0/48
no shutdown
channel-group 100 mode active
exit
3.查看命令
思科的Catalyst和Nexus系列查看命令是不一样的
3.1 Catalyst
show etherchannel summary
示例
bash
Cisco-3850#show etherchannel summary
Flags: D - down P - bundled in port-channel
I - stand-alone s - suspended
H - Hot-standby (LACP only)
R - Layer3 S - Layer2
U - in use f - failed to allocate aggregator
M - not in use, minimum links not met
u - unsuitable for bundling
w - waiting to be aggregated
d - default port
Number of channel-groups in use: 11
Number of aggregators: 11

H3C 交换机配置
1. 创建二层聚合接口,并指定为动态LACP模式
bash
interface Bridge-Aggregation 1
port link-type trunk
port trunk permit vlan all
link-aggregation mode dynamic # 启用动态LACP(必须)
link-aggregation load-sharing mode destination-mac # 负载均衡策略 , 属于可选项,可以不加
quit
2. 将物理端口加入聚合组
bash
interface GigabitEthernet 1/0/1
port link-aggregation group 1
quit
interface GigabitEthernet 1/0/2
port link-aggregation group 1
quit
3. (可选)限制选中端口数量
bash
interface Bridge-Aggregation 1
link-aggregation selected-port maximum 2
link-aggregation selected-port minimum 1 # 最少存活链路
✅ 验证命令:
display link-aggregation summary ---- 查看所有聚合接口摘要信息
display link-aggregation verbose ------ 查看所有聚合接口详细信息(S=Selected,U=Unselected)
