一、基础概念理解

链路聚合类型对比

二、二层链路聚合配置（Bridge-Aggregation）
方案1：静态二层聚合（手工模式，最常用）
# 1. 创建二层聚合组
system-view
interface bridge-aggregation 10
description To-Switch-Trunk
link-aggregation mode static
port link-type trunk
port trunk permit vlan all
quit

# 2. 配置物理端口（以Ten-GigabitEthernet 1/0/1-2为例）
interface range ten-gigabitethernet 1/0/1 to ten-gigabitethernet 1/0/2
port link-aggregation group 10
# 如果需要Trunk，在聚合组配置即可，这里不需要重复配置
quit

# 3. 可选：配置负载分担算法
link-aggregation load-sharing mode destination-ip source-ip destination-port source-port
方案2：动态LACP聚合（推荐，自动检测）
# 1. 创建LACP聚合组
system-view
interface bridge-aggregation 20
description LACP-to-Core
link-aggregation mode dynamic
port link-type trunk
port trunk permit vlan 10 20 30
lacp system-priority 100
quit

# 2. 配置物理端口
interface range ten-gigabitethernet 1/0/3 to ten-gigabitethernet 1/0/4
port link-aggregation group 20
lacp period short # 快速模式，默认是30秒，short是1秒
quit
三、三层链路聚合配置（Route-Aggregation）
方案1：静态三层聚合
# 1. 创建三层聚合接口
system-view
interface route-aggregation 100
description Uplink-to-Router
ip address 192.168.100.1 255.255.255.252
link-aggregation mode static
quit

# 2. 将物理端口加入聚合组
interface range ten-gigabitethernet 1/0/5 to ten-gigabitethernet 1/0/6
port link-aggregation group 100
quit
方案2：动态LACP三层聚合
# 1. 创建LACP三层聚合接口
system-view
interface route-aggregation 101
description LACP-Uplink
ip address 10.1.1.1 255.255.255.0
link-aggregation mode dynamic
quit

# 2. 配置物理端口
interface range ten-gigabitethernet 1/0/7 to ten-gigabitethernet 1/0/8
port link-aggregation group 101
lacp period short
quit
四、完整配置示例
示例1：双上行到两台核心交换机（跨设备链路聚合）
# 配置M-LAG（跨设备链路聚合），需要两台S5830
# 设备A配置
system-view
# 创建M-LAG域
m-lag
system-mac 0001-0001-0001
system-number 1
system-priority 100
quit

# 配置M-LAG Peer-Link（用于M-LAG设备间同步）
interface bridge-aggregation 1
port link-type trunk
port trunk permit vlan all
link-aggregation mode dynamic
quit
interface ten-gigabitethernet 1/0/49
port link-aggregation group 1
quit
interface ten-gigabitethernet 1/0/50
port link-aggregation group 1
quit

# 创建M-LAG聚合组
interface bridge-aggregation 10
port link-type trunk
port trunk permit vlan 10 20
m-lag group 10
quit

# 加入物理端口
interface ten-gigabitethernet 1/0/1
port link-aggregation group 10
quit
示例2：三层聚合网关配置
# 创建三层聚合作为VLAN网关
system-view
vlan 100
name Server-VLAN
quit

interface route-aggregation 1
description Server-Farm-Gateway
ip address 172.16.100.1 255.255.255.0
link-aggregation mode dynamic
quit

# 将三层聚合接口加入VLAN
vlan 100
port route-aggregation 1
quit
五、高级配置选项
1. 负载分担算法配置
# 查看当前负载分担模式
display link-aggregation load-sharing mode

# 设置基于流的负载分担
link-aggregation global load-sharing mode ?
# 可选模式：
# destination-ip 目的IP
# destination-mac 目的MAC
# destination-port 目的端口
# source-ip 源IP
# source-mac 源MAC
# source-port 源端口
# enhanced 增强模式

# 示例：基于源目的IP和端口
link-aggregation global load-sharing mode destination-ip source-ip destination-port source-port

# 针对特定聚合组设置
interface bridge-aggregation 10
link-aggregation load-sharing mode destination-ip source-ip
quit
2. 链路故障检测优化
# 配置BFD快速检测
bfd
quit

interface bridge-aggregation 10
lacp fast-timeout enable
bfd min-transmit-interval 100
bfd min-receive-interval 100
bfd detect-multiplier 3
quit
3. 链路聚合安全配置
# 开启LACP系统保护
lacp system-protection enable

# 配置LACP超时时间
interface ten-gigabitethernet 1/0/1
lacp period short # 短超时（1秒）
# lacp period long # 长超时（30秒，默认）
quit
六、配置验证与诊断
1. 查看聚合状态
# 查看所有聚合组摘要
display link-aggregation summary

# 查看特定聚合组详细信息
display link-aggregation verbose bridge-aggregation 10
display link-aggregation verbose route-aggregation 100

# 查看成员端口状态
display interface bridge-aggregation 10
display interface route-aggregation 100

# 查看LACP状态
display lacp system-id
display lacp statistics interface bridge-aggregation 10
2. 查看流量统计
# 查看聚合组流量
display counters interface bridge-aggregation 10
display counters rate interface bridge-aggregation 10

# 查看负载分担情况
display link-aggregation load-sharing interface bridge-aggregation 10
3. 调试命令
# 开启调试信息（谨慎在生产环境使用）
debugging lacp all
terminal debugging
terminal monitor

# 查看日志
display logbuffer
七、故障排查指南
常见问题1：聚合组无法UP
# 1. 检查物理链路
display interface ten-gigabitethernet 1/0/1 brief

# 2. 检查端口配置一致性
display current-configuration interface ten-gigabitethernet 1/0/1
display current-configuration interface ten-gigabitethernet 1/0/2

# 3. 检查LACP协商状态
display lacp statistics interface bridge-aggregation 10
常见问题2：流量不均衡
# 1. 检查负载分担模式
display link-aggregation load-sharing mode

# 2. 检查流量统计
display counters interface bridge-aggregation 10
reset counters interface bridge-aggregation 10
# 等待一段时间后再次查看
display counters interface bridge-aggregation 10
八、最佳实践建议
1. 端口选择原则
# 使用相同速度的端口
# 使用相邻的端口（便于管理）
# 避免跨线卡的聚合（如果支持，确保性能）

interface range ten-gigabitethernet 1/0/1 to ten-gigabitethernet 1/0/4
interface range ten-gigabitethernet 2/0/1 to ten-gigabitethernet 2/0/4
2. VLAN配置建议
# 在聚合组上配置VLAN，而不是单个端口
interface bridge-aggregation 10
port link-type trunk
port trunk permit vlan 10 20 30
port trunk pvid vlan 10
quit
3. 聚合组命名规范
# 创建描述性名称
interface bridge-aggregation 10
description TO-CORE-SW_LACP
quit

interface route-aggregation 100
description TO-FIREWALL_STATIC
quit
九、配置文件示例

sysname S5830-1
vlan 10
name Data
vlan 20
name Voice
vlan 30
name Management

interface bridge-aggregation 1

port link-aggregation group 1
mtu 9216

interface ten-gigabitethernet 1/0/48
port link-aggregation group 1

十、重要注意事项
端口一致性要求：
相同速率和双工模式
相同的VLAN配置
相同的STP设置
相同的QoS配置
最大聚合组限制：
S5830支持的最大聚合组数：128个
每个聚合组最大端口数：8个
实际限制请参考具体型号规格
LACP最佳实践：
两端都配置LACP模式
使用相同的LACP系统优先级
配置快速超时（short）以加快故障检测
故障切换时间：
静态聚合：秒级收敛
LACP长超时：30-90秒
LACP短超时：3-9秒
结合BFD：毫秒级
保存配置：
save force
