Dell EMC SmartFabric OS10 User Guide Release 10.5.0

Collector configuration 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] [max-datagram-size datagram-size-number] 

The no form of the command disables sFlow collectors in CONFIGURATION mode.

Collector configuration for nondefault VRF

If you configure a collector for a nondefault VRF, create the VRF first. If you do not specify the VRF instance, the system configures the collector for the default VRF instance.

The following are the steps to configure 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
