Router Configuration Guide 741
rate
Syntax rate sample-rate
no rate
Context config>cflowd
Description This command specifies the rate (N) at which traffic is sampled and sent for flow analysis. A packet is
sampled every N packets; for example, when sample-rate is configured as 1, then all packets are sent
to the cache. When sample-rate is configured as 100, then every 100th packet is sent to the cache.
The no form of this command resets the sample rate to the default value.
Default 1000
Parameters sample-rate — Specifies the rate at which traffic is sampled.
Values 1 to 10000
template-retransmit
Syntax template-retransmit seconds
no template-retransmit
Context config>cflowd
Description This command specifies the interval for sending template definitions.
Default 600
Parameters seconds — The value expressed in seconds before sending template definitions.
Values 10 to 600
use-vrtr-if-index
Syntax [no] use-vrtr-if-index
Context config>cflowd
Description This command is used to export flow data using interface indexes (ifIndex values), which can be used
directly as the index into the IF-MIB tables for retrieving interface statistics. Specifically, if the this
command is enabled, then the ingressInterface (ID=10) and egressInterface (ID= 14) fields in IP flow
templates used to export the flow data to Cflowd version 9 and version 10 collectors will be populated
with the IF-MIB ifIndex of that interface. In addition, for version 10 templates, two fields are available
in the IP flow templates to present the Virtual Router ID associated with the ingress and egress
interfaces.
