链路聚合互联不通

两台交换机一台S5130S，另一台S6520X，两台都配置了二层动态链路聚合作互联，配置如下：

 S5130S

 interface Bridge-Aggregation1 

 port link-type trunk 

 port trunk permit vlan all

 link-aggregation mode dynamic

 # interface GigabitEthernet1/0/51

 port link-type trunk 

 port trunk permit vlan all 

 port link-aggregation group 1 

# interface GigabitEthernet1/0/52 

 port link-type trunk 

 port trunk permit vlan all 

 port link-aggregation group 1 

# 

 S6520X

 interface Bridge-Aggregation44

 port link-type trunk

 port trunk permit vlan all 

 link-aggregation mode dynamic

 #

 interface Ten-GigabitEthernet1/0/44

 port link-mode bridge

 port link-type trunk

 port trunk permit vlan all

 port link-aggregation group 44 

#

 interface Ten-GigabitEthernet2/0/44

 port link-mode bridge 

 port link-type trunk

 port trunk permit vlan all

 port link-aggregation group 44

一台是千M网卡一台是万M网卡，都用了万M光模块 光纤互联起来之后没有UP，指示灯不亮，请问这是配置问题还是物理上的问题呢？
