问题描述：
配置如下：
vlan 62 (远程镜像vlan62，目的端口为g1/0/1 g1/0/2 这个vlan只给远程镜像用)
mirroring-group 1 remote-source
mirroring-group 1 remote-probe vlan 62
interface GigabitEthernet1/0/1
port access vlan 62
#
interface GigabitEthernet1/0/2
port access vlan 62
interface GigabitEthernet1/0/7
port access vlan 330
mirroring-group 1 mirroring-port both
#
interface GigabitEthernet1/0/8
port access vlan 330
mirroring-group 1 mirroring-port both
#
interface GigabitEthernet1/0/9
port access vlan 330
mirroring-group 1 mirroring-port both
#
interface GigabitEthernet1/0/10
port access vlan 330
mirroring-group 1 mirroring-port both
#
interface GigabitEthernet1/0/11
port access vlan 330
mirroring-group 1 mirroring-port both
#
interface GigabitEthernet1/0/12
port access vlan 330
mirroring-group 1 mirroring-port both
interface GigabitEthernet1/0/30
mirroring-group 1 reflector-port
状态：
dis mirroring-group 1
Mirroring group 1:
Type: Remote source
Status: Active
Mirroring port:
GigabitEthernet1/0/7 Both
GigabitEthernet1/0/8 Both
GigabitEthernet1/0/9 Both
GigabitEthernet1/0/10 Both
GigabitEthernet1/0/11 Both
GigabitEthernet1/0/12 Both
Reflector port: GigabitEthernet1/0/30
Remote probe VLAN: 62
组网及组网描述：
请问这个配置有问题吗？现在电话录音的反应他们收不到镜像口的部分流量

是MSTP吗？看一下镜像源端口都在同一颗树里吗？之前见过同芯片的端口不在一棵树里，有的端口被阻塞了，其他端口的流量不能镜像的
是默认的STP 没起mstp
