configure flowstats filter ports
Usage Guidelines
Configuring a filter specification enables that filter for the specified ports. To specify all ports, you can
use specify them as the range of all ports (such as 1-32 or 7:1-7:4) or in the form <slot>:* on a modular
switch.
Each Ethernet port supports eight filters for ingress flows.
Conceptually, the filters work by ANDing the contents of each of the five components of a forwarded
flow with the associated masks from the first defined filter (filter #1). Statistics are maintained if the
results of the AND operations match the configured filter values for all fields of the sequence. 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 or all of the sequence components
can be configured with a single command.
Example
The following command example configures filter 2 to collect aggregate statistics for all traffic flowing
through ports 1-8 from the 192.170.0.0/16 subnet to the 192.171.132.0/24 subnet:
configure flowstats filter 2 aggregation export 1 ports 1-8 ingress dest-ip
192.171.132.0/24 source-ip 192.170.0.0/16 dest-port 0/0 source-port 0/0 protocol ip
The following command configures filter 3 to collect statistics on any flows for ports 4-32 that did not
match the filters defined in filters 1 and 2:
configure flowstats filter 3 aggregation export 1 ports 4-32 ingress match-all-flows
