This attribute is only relevant for HW Compression VCs
configured for CPC, 8K history. It indicates the Search
Depth configured for this circuit. Increasing this attribute
may allow the user to achieve better Compression ratios.
This however could occur at the expense of throughput
(i.e. you may get better compression ratios, but lower
throughput). Note that this value may be set to 0, if the
user wishes to run this circuit in High Speed mode.
Note that the default value of 256 is actually used to
indicate that that this attribute should be inherited from
wfWcpLineEntry MIB & is not a valid search depth value.
Valid Search Depth values lie within the 1..255 range.
