timeout value will become 400 automatically.

of the flow samplers and counter pollers associated with this analyzer server will be
deleted. “Infinite” indicates that the analyzer server will nev er time out. If not specified, the
default value is 400.
Collector Address The IP address of the analyzer server. If not specified, the address will be 0.0.0. 0 which
means that the entry will be inactive.
Collector Port (1-65535) The destination UDP port for sending the sFlow datagrams. If not s pecified, the default
value is 6364.

Parameter Description
From Port / To Port Specifies the port or list of ports to be configured.
Analyzer Server ID (1-
4) The analyzer server id specifies the ID of a server analyzer where the packet will be
forwarded.
Rate (0-65535) The sampling rate for packet sampling. The actual rate is the configured ra te value
multiplied by 256. For example, if the rate is 20, the actual rate 5120. One packet will be
sampled from about 5120 packets. If set to 0, the sampler is disabled. If the rate is not
specified, its default value is 0.
MAX Header Size (18-
