Viewing Cluster Correction Statistics

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 R80.30 Performance Tuning Administration Guide.
