12508 can only capture unidirectional packets after local mirroring is configured in both directions

NULL

Users reported that after configuring local port mirroring on 12508, only one-way packets can be actively sent, and the device is suspected of failure .

Check the configuration and find that the port mirroring configuration is normal configuration: 

  mirroring-group 2 local

interface GigabitEthernet1/6/0/32 

 port link-mode bridge 

mirroring-group 2 monitor-port 

# interface Ten-GigabitEthernet1/4/0/18 

 port link-mode bridge

 port link-type trunk 

 undo port trunk permit vlan 1 

 port trunk permit vlan 114 4019 

 qos apply policy SW-02 inbound 

 mirroring-group 2 mirroring-port both 

However, it was found that in addition to the local mirror configuration, streaming mirroring was also configured on site, that is, both local mirroring and streaming mirroring were configured. 

 traffic classifier SW-02 operator 

and if-match acl 3334

traffic behavior SW-02 

 mirror-to vlan 500 

qos policy SW-02 

 classifier SW-02 behavior SW-02

The device has restrictions. When local port mirroring and flow mirroring are configured at the same time, only flow mirroring takes effect  

Cancel flow mirroring to make local mirroring effective  .
