Configuring 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.
• Identify sFlow collectors to which sFlow datagrams are forwarded.
CONFIGURATION mode
sflow collector ip-address agent-addr ip-address [number [max-datagram-size
number] ] | [max-datagram-size number ]
The default UDP port is 6343.
The default max-datagram-size is 1400.
Changing the 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 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.
To configure the polling intervals globally (in CONFIGURATION mode) or by interface (in INTERFACE
mode), use the following command.
