M9000-X聚合口无法选中

两台M9000设备做RBM，使用0/1/1、0/1/2、1/1/1、1/1/2接口作为keepalive口，编号agg100。

设备聚合组agg100中有四个接口，只有一个能选中：

Aggregate Interface: Route-Aggregation100

Creation Mode: Manual

Aggregation Mode: Dynamic

Loadsharing Type: Shar

System ID: 0x8000, 6ce2-d331-4a00

Local:

  Port             Status  Priority Oper-Key  Flag

--------------------------------------------------------------------------------

  HGE0/1/1         U       32768    1         {ACG}

  HGE0/1/2         U       32768    1         {ACG}

  HGE1/1/1         S       32768    1         {ACDEF}

  HGE1/1/2         U       32768    1         {ACG}

 1、查看两端接口下配置：

设备一：

#

interface HundredGigE1/1/1

port link-mode route

port link-aggregation group 100

#

interface HundredGigE1/1/2

port link-mode route

port link-aggregation group 100

#

 #

interface Route-Aggregation100

ip address 1.1.1.2 255.255.255.252

link-aggregation mode dynamic

#

 设备二：

interface HundredGigE1/1/1

port link-mode route

port link-aggregation group 100

#

interface HundredGigE1/1/2

port link-mode route

port link-aggregation group 100

#

#

interface Route-Aggregation100

ip address 1.1.1.1 255.255.255.252

link-aggregation mode dynamic

 两边一致，且能选中的端口以及未选中的端口配置一致。

2、查看dis link-aggregation memb

HundredGigE1/1/1:

Aggregate Interface: Route-Aggregation100

Local:

    Port Number: 1

    Port Priority: 32768

    Oper-Key: 1

Remote:

    Port Number: 0

    Port Priority: 32768

    Oper-Key: 0

    Flag: {DEF}

Received LACP Packets: 0 packet(s)

Illegal: 0 packet(s)

HundredGigE1/1/1:

Aggregate Interface: Route-Aggregation100

Local:

    Port Number: 1

    Port Priority: 32768

    Oper-Key: 1

    Flag: {ACG}

Remote:

    System ID: 0x8000, 0000-0000-0000

    Port Number: 0

    Port Priority: 32768

    Oper-Key: 0

    Flag: {DEF}

Received LACP Packets: 0 packet(s)

Illegal: 0 packet(s)

Sent LACP Packets: 172 packet(s)

都只发没收。

看着设备动态聚合没有什么限制。

以及没有配置最大选中数。

3、debug查看debug link-agg lacp packet all。

只有选中的接口有收发记录，未选中接口都是有发无收，两端设备debug现象一致。

观察logbuffer，发现有此记录：

查看安装手册：

对交换网板的安装有限制，现场未按照规定安装

规范安装后问题解决。
