Some math is involved, but what I did is set it to the maximum permitted, however your environments may vary. As you can imagine, this could result in useless netflow statistics. So, if our sampler was configured for 1 out of 1000, the actual sampling rate would be 1 out of 100,000. This says that whatever sampling rate you have configured, we will only sample 1 of those packets out of every 100. The bottom part is important to understand. Recommended sampler is 1 out-of 4956 to avoid rate limiting.Р”Р„n additional 1:100 sampler, over the configured sampler is applicable for F2/F2e ports N7K1(config-if)# ip flow monitor netflow-monitor-1 input sampler netflow-sampler N7K1(config-flow-sampler)# mode 1 out-of 1000 So, letРІР‚в„ўs configure a sampler to sample 1 out of every 1000 packets: N7K1(config)# sampler netflow-sampler N7K1(config-if)# ip flow monitor netflow-monitor-1 inputР”В®RROR: A sampler must be configured for an interface on an F2 card or F2e mixed vdc An error will prompt when trying to configure this in a mixed environment: N7K1(config)# interface vlan 10 The CPU will automatically rate limit netflow traffic to 1 out of a 1000 packets to protect the control plane. Due to the РµвЂ¦С“ proxy routing required for F2(e), netflow traffic is CPU processed. Netflow samplers become important when youРІР‚в„ўre running mixed M1/F2(e) VDCs. The CPU features 8 cores, running at 1.7Ghz with 16MB of cache. The X86 processor in the Nexus 3550-T platform is an Intel Atom C3708 SoC, built into a third-party System on Module (SoM). Apply the Netflow Monitor to the your РµвЂ¦С“ interfaces interface eth3/10 The FPGA in the Cisco Nexus 3550-T is a Xilinx Virtex UltraScale+ HBM xcvu35p-fsvh2892-3-e. You can also apply multiple exporters to the same monitor: flow monitor netflow-monitor-3Р”Тђ. Or you can use the built-in Netflow Flow Record: flow monitor netflow-monitor-2 NX-OS interface supported exclusively on Nexus brand switches. IOS interface that is nearly identical to the Cisco router IOS, except for switching-specific commands.

This port-channel will be using the source and destination mac addresses for. Catalyst OS (CatOS) - interface based on set commands, that is almost entirely deprecated. The above command creates a port-channel with id 1. To create a port-channel, use the following command: admin NX - 3550 - T configure interface port-channel1 load-balance src-dst-mac. flow exporter exporter-1Р”Р‡low Monitors bind the Flow Record to the Flow Exporter flow monitor netflow-monitor-1 The Nexus 3550-T enables users to create port-channels by using the CLI.

Unlike IOS, there are few steps involved to get Netflow functioning, here is a quick run down:Р”Тђ. For CCIE:DC purposes, an understanding of how NetFlow is configured in NXOS cannot hurt, especially since it is mentioned in the blueprint (1.5.b РІР‚вЂњ Implement Netflow). This post is a part of my CCIE:DC studies, but will be useful for anyone needing to quickly configure NetFlow in NXOS.
