Syntax sflow-create

name name-string	Specify a name for the sFlow collector.
type ingress\|egress	Specify the type of packet for the sflow agent. Specify ingress to capture incoming packets and egress for outgoing packets.

ports port-list	Specify the list of ports to capture packets.
sample-rate sample-rate-number	Specify the rate of packet sampling by the sflow agent.
sample-interval sample-inverval- number	Specify the interval between packet captures.
trunc-length trunc-length-number	Specify the truncated length of the captured packet.
vnet vnet-name	Specify the VNET for sFlow.
vlan vlan-id	Specify the VLAN to apply to the sFlow agent. The value can be from 0 to 4095.
agent-id ip-address	Specify the IP address of the sFlow agent.

Defaults None.

sflow-collector-create

sFlow is an industry standard technology that monitors high speed switched networks. An sFlow collector gathers information from sFlow agents on the network. An sFlow collector can have a scope of local or fabric.

collector-port collector-port-number	Specify the port number for the sFlow collector.
name name-string	Specify a name for the sFlow collector.
scope [local\|fabric]	Specify a scope, either fabric or local.

Defaults None.

Access CLI

History Command introduced in nvOS Version 1.2.1

Usage This command is used to create an sFlow collector to gather information from the sFlow agents on the network.

Examples To create the sFlow collector, sFlow-local, with the IP address of 192.168.18.37 on port 44, and the scope local, use the following syntax:

CLI network-admin@switch > sflow-collector-create collector-ip 192.168.18.37 collector-port 37 name sflow-local scope local
