Specify Collectors
The sflow collector command allows identification of sFlow collectors to which sFlow datagrams are
forwarded. You can specify up to two sFlow collectors. If you specify two collectors, the samples are sent
to both.
To identify sFlow collectors, use the following command:
Polling Intervals
The sflow polling-interval command configures the polling interval for an interface in the maximum number
of seconds between successive samples of counters to be sent to the collector. This command changes the
global default counter polling (20 seconds) interval. You can configure an interface to use a different
polling interval.
You can configure the polling interval globally (in CONFIGURATION mode) or by interface (in
INTERFACE mode) by executing the following
interval command:
