Collector conguration
Congure the IPv4 or IPv6 address for the sFlow collector. You must enter a valid and reachable IPv4 or IPv6 address. You can congure a
maximum of two sFlow collectors. If you specify two collectors, the samples are sent to both. The agent IP address must be the same for
both the collectors.
• Enter an IPv4 or IPv6 address for the sFlow collector, IPv4 or IPv6 address for the agent, UDP collector port number, maximum
datagram size, and the VRF instance number in CONFIGURATION mode.
sflow collector {ip-address | ipv6-address} agent-addr {ip-address | ipv6-address} [collector-
port-number] [vrf default]
The no form of the command disables sFlow collectors in CONFIGURATION mode.

Polling-interval conguration
The polling interval for an interface is the number of seconds between successive samples of counters sent to the collector. You can
congure the duration for polled interface statistics. Unless there is a specic deployment need to congure a lower polling interval value,
congure the polling interval to the maximum value.
• Change the default counter polling interval in CONFIGURATION mode, from 10 to 300. The default is 20.
