Description
This command lets you view the Cluster Correction Statistics on each Cluster Member.
From R80.20, ClusterXL adds a new mechanism to deal with asymmetric connections - Cluster Correction Layer (CCL).
The CCL provides connections stickiness by "correcting" the packets to the correct Cluster Member:
In some cases, ClusterXL needs to send some data along with the corrected packet (currently, only in VPN). For such packets, the output shows "with metadata".
Note - For more information about CoreXL, see the R80.20 Performance Tuning Administration Guide.
