sFlow TABLE
A set of sFlow(R) targets. sFlow is a protocol for remote
monitoring of switches.
Summary:
agent optional string
header optional integer
polling optional integer
sampling optional integer
targets set of 1 or more strings
Common Columns:
external_ids map of string-string pairs
Details:
agent: optional string
Determines the agent address, that is, the IP address
reported to collectors as the source of the sFlow data. It
may be an IP address or the name of a network device. In
the latter case, the network device's IP address is used,
If not specified, the agent device is figured from the
first target address and the routing table. If the routing
table does not contain a route to the target, the IP
address defaults to the local_ip in the collector's
Controller.
If an agent IP address cannot be determined, sFlow is
disabled.
header: optional integer
Number of bytes of a sampled packet to send to the
collector. If not specified, the default is 128 bytes.
polling: optional integer
Polling rate in seconds to send port statistics to the
collector. If not specified, defaults to 30 seconds.
sampling: optional integer
Rate at which packets should be sampled and sent to the
collector. If not specified, defaults to 400, which means
one out of 400 packets, on average, will be sent to the
collector.
targets: set of 1 or more strings
sFlow targets in the form ip:port.
Common Columns:
The overall purpose of these columns is described under Common
Columns at the beginning of this document.
external_ids: map of string-string pairs
