Collector conguration
Congure the IPv4 or IPv6 address for the sFlow collector. When you congure the collector, enter a valid and reachable IPv4 or IPv6
address. You can congure a maximum of two sFlow collectors. If you specify two collectors, samples are sent to both. The agent IP
address must be the same for both the collectors.
Collector conguration for default VRF
• Enter an IPv4 or IPv6 address for the sFlow collector, IPv4 or IPv6 address for the agent, UDP collector port number, and maximum
datagram size in CONFIGURATION mode.
sflow collector {ip-address | ipv6-address} agent-addr {ip-address | ipv6-address} [collector-
port-number
]
The no form of the command disables sFlow collectors in CONFIGURATION mode.
Collector conguration for nondefault VRF
If you congure a collector for a nondefault VRF, create the VRF rst. If you do not specify the VRF instance, the system congures the
collector for the default VRF instance.
The following are the steps to congure sFlow collector with a nondefault VRF:
1 Create a nondefault VRF instance.
OS10(config)# ip vrf RED
2 Enable the sFlow feature.
OS10(config)# sflow enable
3 Assign an IP address to an interface which you can use as the sFlow agent and add it to the VRF instance.
OS10(conf-if-eth1/1/1)# sflow enable
OS10(conf-if-eth1/1/1)# ip vrf forwarding RED
OS10(conf-if-eth1/1/1)# ip address 1.1.1.1/24
OS10(conf-if-eth1/1/1)# no shutdown
4 Assign an IP address to an interface through which the sFlow collector is reachable and add it to the VRF instance.
OS10(conf-if-eth1/1/1)# interface ethernet 1/1/2
OS10(conf-if-eth1/1/2)# sflow enable
OS10(conf-if-eth1/1/2)# ip vrf forwarding RED
OS10(conf-if-eth1/1/2)# ip address 4.4.4.4/24
OS10(conf-if-eth1/1/2)# no shutdown
5 Enter the IP addresses of the sFlow collector and the agent and assign them to the VRF instance.
OS10(config)# sflow collector 4.4.4.1 agent-addr 1.1.1.1 vrf RED
