PoS Commands
Usage Guidelines
The command allows a port to be configured to selectively maintain statistics for only those flows that
match the specified filters. Sixteen filters are supported for each port, eight filters for ingress flows and
another eight filters for egress flows. The
keyword are specified to identify the filter that is being configured. The
in the range [1..8]. The filters are comprised of a value/filtermask pair for each component of the
{destination IP address, source IP address, destination port number, source port number, protocol}
5-tuple. Conceptually, the filters work by ANDing the contents of each 5-tuple component of a
forwarded flow with the associated masks from filter#1. Statistics are maintained if the results of the
AND operations match the configured filter values for all fields of the 5-tuple. If there is no match, then
the operation is repeated for filter#2, and so on. If there is no match for any of the filters, then statistics
are not maintained for the flow. Filters for any/all of the 5-tuple components can be configured with a
single command.
The parameter also supports the
filterspec
keyword adjusts the settings such that the filter matches any flow (that is, the
match-all-flows
value/filtermask pairs are set to 0/0 for all the 5-tuple components), while the
keyword adjusts the settings such that the filter does not match any flow.
The optional
aggregation
maintained for all the flows that match the filter, which can substantially reduce the volume of exported
data. A particular export distribution group may also be specified on a filter-basis. The
parameter identifies the set of collector devices that records for flows matching the filter are to be
exported to.
