QVb3Ox,H3C S10506X两台做DRNI

问题描述：

H3C S10506X两台做DRNI，上联至锐捷设备，其中并采用lacp的方式进行链路聚合。但是上联口T1/0/1出现了附件中的log,并出现网路中断

1、请问SW1出现XGE1/0/1口反复出现down的原因？

2、我做了DRNI，SW2上并没有出现相关down的告警，为什么网络业务会中断？我理解是SW1口down了流量会走SW2对应的口

SW1：

%Mar 12 13:51:18:731

sw2：

%Mar 12 13:35:36:018

组网及组网描述：

您好，参考

# 查看Device A上分布式聚合的Keepalive报文信息。

[DeviceA] display drni keepalive

Neighbor keepalive link status: Up

Neighbor is alive for: 104 s, 16 ms

Last keepalive packet sending status: Successful

Last keepalive packet sending time:

Last keepalive packet receiving status: Successful

Last keepalive packet receiving time:

Distributed relay keepalive parameters:

Destination IP address: 1.1.1.1

Source IP address: 1.1.1.2

Keepalive UDP port : 6400

Keepalive VPN name : N/A

Keepalive interval : 1000 ms

Keepalive timeout  : 5 sec

Keepalive hold time: 3 sec

以上信息表明Device A和Device B设备间无故障。

  GE1/0/4             32768    32772    40004    0x7b  , 0001-0001-0001 {ACDEF}

以上信息表明，Device C的端口GigabitEthernet1/0/1～GigabitEthernet1/0/4均处于选中状态，此时Device C将DeviceA和DeviceB认为是一台设备，从而实现了跨设备的聚合。

请问这个参考是用来确认什么的呢？
