configure flowstats filter ports
ExtremeWare 7.7 Command Reference Guide 677
configure flowstats filter ports
configure flowstats filter <filter#> {aggregation} {export <group#>} ports
<portlist> [ingress | egress] <filterspec>
Description
Configures a flow record filter for the specified ports.
NOTE
This command is available only on the “i” series switches.
Syntax Description
Default
N/A
Usage Guidelines
Configuring a filter specification enables that filter for the specified ports. To specify all ports, you can
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 up to eight filters for ingress flows.
filter# The
filter#
parameter is an integer in the range from 1 to 8 that identifies the filter being
defined.
<group#> Specifies the group number that identifies the set of flow collector devices to which records for
flows matching the filter are to be exported. If Group is not specified, then group # 1 will be used
as default export group.
aggregation To reduce the volume of exported data, use this optional keyword to maintain a single set of
statistics for all the flows that match the specified filter.
filterspec Specifies a set of five parameters (four are value/mask pairs) that define the criteria by which a
flow is evaluated to determine if it should be exported. The parameters are:
[{dest-ip <ipaddress_value/mask ipaddress_filtermask>} {source-ip
<ipaddress_value/mask ipaddress_filtermask>} {dest-port
<port_value/port_filtermask>} {source-port <port_value/port_filtermask>}
{protocol <tcp/udp/ip/protocol_value/protocol_filtermask>} |
match-all-flows |match-no-flows]
All five specifications must be included in the order specified.
The range for port/port_mask is calculated using the following formula:
minport = port, maxport = 2^(32-port_mask)-1).
match-all-flows
specifies that the filter should match any flow.
match-no-flows
specifies that the filter should discard all flow. This option is not valid for
Ethernet modules.
egress Specifies that the filter should capture only egress traffic. This option is not valid for Ethernet
modules.
ingress Specifies that the filter should capture only ingress traffic.
