Packet Over SONET Module Installation and User Guide
To specify a particular export distribution group on a per-filter basis,
use the optional export keyword with a group number value to
identify the set of flow collector devices to which records for flows
matching the filter are to be exported. If you do not specify a value
for group#, the value defaults to 1.
Use this keyword to specify that the filter being defined in the
command is one of the eight filters to be applied to ingress flows.
Use this keyword to specify that the filter being defined in the
command is one of the eight filters to be applied to egress flows.
Each filter is defined using a value/filtermask pair for each of the five
components in the following sequence:
{destination IP address, source IP address,
destination port number,
source port number, protocol}
in the form:
[{dest-ip <ipaddress_value/ipaddress_filtermask>}
{source-ip <ipaddress_value/ipaddress_filtermask>}
{dest-port <port_value/port_filtermask>}
{source-port <port_value/port_filtermask>}
{protocol <protocol_value/protocol_filtermask>} |
match-all-flows | match-no-flows]
The ipaddress_filtermask, port_filtermask, and
protocol_filtermask parameters are configured using
hexadecimal notation.
You can also use either the match-all-flows keyword or the
match-no-flows keyword in place of settings for the five
components. The match-all-flows keyword adjusts the
value/filtermask settings for all the components to 0/0 such that the
filter matches any flow. The match-no-flows keyword adjusts the
value/filtermask settings for all the components such that the filter
does not match any flow.
By default, filter #1 is configured to match-all-flows, and the
remaining filters are configured to match-no-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.
