4.13 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.

4.13.1 sflow receiver

Use this command to configure the sFlow collector parameters (owner string, receiver timeout, max datagram size,

IP address, and port).

Format cablestatus <slot/port>

Mode Privileged EXEC

Field Description

Cable Status One of the following statuses is returned:

•Normal: The cable is working correctly.

•Open: The cable is disconnected or there is a faulty connector.

•Short: There is an electrical short in the cable.

• Cable Test Failed: The cable status could not be determined. The cable may in fact be

working.

Cable Length If this feature is supported by the PHY for the current link speed, the cable length is displayed

as a range between the shortest estimated length and the longest estimated length. Note that

if the link is down and a cable is attached to a 10/100 Ethernet adapter, then the cable status

may display as Open or Short because some Ethernet adapters leave unused wire pairs

unterminated or grounded. Unknown is displayed if the cable length could not be determined.

Format sflow receiver <rcvr_idx> owner <owner-string> timeout <rcvr_timeout>

max datagram <size> ip/ipv6 <ip> port <port>

Mode Global Config

Field Description

Receiver Owner The identity string for the receiver, the entity making use of this sFlowRcvrTable entry. The

range is 127 characters. The default is a null string. The empty string indicates that the entry

is currently unclaimed and the receiver configuration is reset to the default values. An entity

wishing to claim an sFlowRcvrTable entry must ensure that the entry is unclaimed before

trying to claim it. The entry is claimed by setting the owner string to a non-null value. The entry

must be claimed before assigning a receiver to a sampler or poller.

Receiver Timeout The time, in seconds, remaining before the sampler or poller is released and stops sending

samples to receiver. A management entity wanting to maintain control of the sampler is

responsible for setting a new value before the old one expires. The allowed range is 0-

4294967295 seconds. The default is zero (0).

Receiver Max

Datagram 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. The

allowed range is 200 to 9116). The default is 1400.

Receiver IP The sFlow receiver IP address. If set to 0.0.0.0, no sFlow datagrams will be sent. The default

is 0.0.0.0.

Receiver Port The destination Layer4 UDP port for sFlow datagrams. The range is 1-65535. The default is

6343.
