Sflow Commands sFlow® is the standard for monitoring high-speed switched and routed networks. sFlow technology is built into network equipment and gives complete visibility into network activity, enabling effective management and control of network resources. The sFlow monitoring system consists of an sFlow Agent (embedded in a switch or router or in a stand-alone probe) and a central sFlow Collector. The sFlow Agent uses sampling technology to capture traffic statistics from the device it is monitoring. sFlow datagrams are used to forward the sampled traffic statistics immediately to an sFlow Collector for analysis. The traffic samples sent to the Collector contain the source ifIndex and, for switched packets, the destination ifIndex. The sFlow Agent supports two forms of sampling: statistical packet-based sampling of switched or routed Packet Flows and time-based sampling of counters. sflow destination Use the sflow destination command to configure the sFlow collector parameters (owner string, receiver timeout, maxdatagram, ip address and port). Use the "no" form of this command to set receiver parameters to the default or remove a receiver. Syntax sflow rcvr_index destination {ip-address [port] | maxdatagram size | owner "owner_string" {notimeout|timeout rcvr_timeout}} no sflow rcvr_index destination [ip-address | maxdatagram | owner] • rcvr_index-The index of this sFlow Receiver (Range: 1-8). • ip-address-The sFlow receiver IP address. If set to 0.0.0.0, no sFlow datagrams will be sent. • size-The maximum number of data bytes that can be sent in a single sample datagram. The management entity should set this value to avoid fragmentation of the sFlow datagrams. (Range: 200-9116 bytes). Switch Management Commands 2276
