为什么我的ae接口链路类型关闭但物理接口打开？
在我的汇聚层 Switch 中，我使用两台 Juniper EX4300 设备实现 Stack：
所以有xe-0/0/x和xe-1/0/x接口。
我创建了ae65接口，在interface中添加了xe-0/0/65.0和xe-1/0/65.0两个接口ae65。
可以看到两个物理端口的Link Type都是up，但是聚合接口ae65 Link Type是down。为什么？
以下是配置：

ether-options {
802.3ad ae65;
}

另一端是具有两个接口的 Juniper EX3300 交换机：

感谢“Phil-Work”，ae65 链接类型变为 Up。我跟着他lacp在EX3300里加了，就可以了。
在我的瞻博网络 EX4300 中，它有一个管理 IP 10.10.10.254/24：
admin@C1-HXJH-A# run show configuration | display set | match "irb unit 2 "
set interfaces irb unit 2 family inet address 10.10.10.254/24
{master:1}[edit]

set vlans vlan2 vlan-id 2
set vlans vlan2 l3-interface irb.2

在 EX3300 中，我还有一个管理 IP 10.10.10.8/24：
...
set interfaces xe-0/1/0 ether-options 802.3ad ae65
set interfaces xe-0/1/1 ether-options 802.3ad ae65

set vlans vlan2 vlan-id 2

...
但他们没有相互交流。不能互相ping通。为什么？
我测试了将ae65.0IP 从更改192.168.65.2/24为10.10.10.65/24，但仍然无法正常工作。10.10.10.65不能10.10.10.8互相ping通。
EDIT-04
我查看EX3300中的MAC地址，显示：
root@LA-C08-A# run show ethernet-switching table brief
Ethernet-switching table: 2 entries, 0 learned, 0 persistent entries
VLAN MAC address Type Age Interfaces
vlan2 * Flood - All-members
vlan2 80:ac:ac:f0:b5:81 Static - Router
在 EX4300 中，没有来自ae65.0.
EDIT-05
我使用monitor traffic捕获 EX4300 ae65 和 EX3300 ae65 所有日志中的包：

这是问题的原因吗？
