The common causes of this type of faults are as follows:


The configuration is incorrect.

Stp block

isolation entries are not deleted.


Troubleshooting method:

1. Run the display dfs-group 1 command to check whether the pairing is normal.

2. Run the display dfs-group 1 node x m-lag command to check whether the M-LAG status is normal.

3. Use common fault locating commands, such as display interface brief/display stp brief/display vlan x, to check the traffic discarding node, STP status, and port PV relationship.

4. Run the diplay system tcam service brief command to check whether the number of isolated ACLs is correct.
