参加链路聚合的两条链路在什么情况下会宕掉其中一条

今天发现一个情况：汇聚端G0/0/23连接核心的G2/0/0/4，汇聚G0/0/24连接核心的G1/0/0/4
汇聚端口配置如下：
interface GigabitEthernet0/0/23
port link-mode bridge
description To_HGPU_SW
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 2 12 to 14 18 33 to 36 129 240 1000 3052 to 3053 3055 3063
port trunk permit vlan 3152 to 3153 3155 3162 to 3163 3201 to 3208 3250 to 3252 3309 3313 3355 to 3358 3360 to 3361 3399
port trunk permit vlan 3404 to 3405 3429 3432 to 3435 3501 to 3504

port trunk permit vlan 3404 to 3405 3429 3432 to 3435 3501 to 3504
port link-aggregation group 1
核心上聚合和端口配置如下：
interface Bridge-Aggregation6

查看端口状态，汇聚端：
Interface            Link Speed   Duplex Type PVID Description
GE0/0/23             UP   1G(a)   F(a)   T    1    To_HGPU_SW
GE0/0/24             UP   1G(a)   F(a)   T    1    TO_HGPU_SW


核心端G0/0/4不能转发数据：
GigabitEthernet1/0/0/4
Current state: UP
Line protocol state: DOWN(LAGG)

请教大神，这是什么原因导致？

你这个不是华为的设备吧

华三交换机做链路聚合时，需要先创建聚合接口，然后在将端口加入到聚合组中
