Viewing Cluster Correction Statistics
In the R81.10.X releases, this command is available starting from the R81.10.15 version.
Description
This command shows the Cluster Correction Statistics on each Cluster Member.
The Cluster Correction Layer (CCL) is a mechanism that deals with asymmetric connections.
The CCL provides connections stickiness by "correcting" the packets to the correct Cluster Member:
-
In most cases, the CCL makes the correction from the CoreXL SND.
-
In some cases (like Dynamic Routing, or VPN), the CCL makes the correction from the Firewall or SecureXL.
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".
