S12508G-AF对出口聚合口进行镜像后，监管端口也为聚合口，聚合口端口会UP/DOWN告警

核心交换机S12508G-AF，对出接口进行镜像后，Bridge-Aggregation13做为监控端口，做完配置后后设备产生告警如下：

%Jun  4 09:40:13:990 2024 csw001&***.***-changsha-2 IFNET/5/LINK_UPDOWN: Line protocol state on the interface Bridge-Aggregation13 changed to down.

聚合口出接口101、102都为 Dynamic

镜像接口配置如下：

interface Ten-GigabitEthernet1/3/0/47

 port link-mode route

 description To-[HNCS-HXSNL4F-S12508-IDC-01]-XGE3/0/1

 mirroring-group 1 mirroring-port both

 lacp period short

 port link-aggregation group 101

#

interface Ten-GigabitEthernet1/3/0/44

 port link-mode route

 description To-[HNCS-HXSNL4F-S12508-IDC-01]-XGE3/0/2

 mirroring-group 1 mirroring-port both

 lacp period short

 port link-aggregation group 101

#

interface Bridge-Aggregation13

 description To-[samasw003&***.***-changsha-2]-mirroring-port

 undo stp enable

link-aggregation mode dynamic

 mirroring-group 1 monitor-port

#

问题：为什么聚合13会产生上面的告警，如何解决？
