华三交换机与华为交换机链路聚合对接失败

不涉及

华三交换机和华为交换机之间起链路聚合，聚合端口无法选中，配置如下：

华为配置：

#

interface Eth-Trunk0

ip address 1.1.1.1 255.255.255.0

mode lacp-static

alias RAGG1

#

华三配置：

# 

interface Route-Aggregation1000

 link-aggregation mode dynamic 

#

配置完成后发现本端display link-aggregation verbose查看聚合组1000状态，两个端口均为不选中状态

Aggregate Interface: Route-Aggregation1000

Creation Mode: Manual

Aggregation Mode: Dynamic

Loadsharing Type: Shar 

Management VLANs: None 

System ID: 0x8000, 9023-b4cf-6d52 

Local: 

 Port Status Priority Index Oper-Key Flag 

 GE1/0/13 U 32768 5 3 {ACD} 

 GE1/0/14 U 32768 6 3 {ACD} 

Remote: 

 Actor Priority Index Oper-Key SystemID Flag

 GE1/0/13 32768 1 49 0x8000, ccd7-3c3c-b3c4 {ACG} 

 GE1/0/14 32768 2 49 0x8000, ccd7-3c3c-b3c4 {ACG}

怀疑LACP报文交互有问题，于是在两端分别开启debug如下：

华为侧debug显示丢弃LACP报文的原因在于报文长度错误为114，正确的报文长度应为110.但是通过华三debug可以看出，我们发出的LACP报文长度为110

查看配置发现客户有配置link-aggregation lacp traffic-redirect-notification enable，这条命令配置后可能会影响与其他厂商设备的聚合配置。

删除该命令后可以正常对接。
