Header Compression Statistics
Column
Description
Index
These statistics are shown on a per-QoS rule basis. This index number
will match with the Index number of the QoS table as seen per the
Configuration | WAN | QoS page for all data being routed. In this way you
can see how each type of defined traffic is compressing on a per-rule
basis.
Pre-Comp. Bytes
Total byte count of all packets since last clear that meet this QoS rule Index before
header compression.
Post-Comp. Bytes
Total byte count of all packets since last clear that meet this QoS rule Index after header
compression.
% Savings
Calculated as: (Pre-Comp Bytes – Post-Comp Bytes) / Pre-Comp Bytes
Total Packets
The total number of packets since last clear that meet this QoS rule Index and were sent
to the header compression engine.
Full Header Packets
The number of packets since last clear in this QoS rule Index that could not be
compressed. Compare this to the Total Packets for the same QoS index to see what % of
packets of this type are compressible.
Error Packets
The number of packets since last clear in this QoS rule Index that compressed with an
error.
