Transition Networks SISPM1040-3xxx-L Web User Guide Parameter descriptions: Agent Configuration IP Address : The IP address used as Agent IP address in sFlow datagrams. It serves as a unique key that will identify this agent over extended periods of time. Both IPv4 and IPv6 addresses are supported. Receiver Configuration Owner : Basically, sFlow can be configured in two ways: through local management using the Web or CLI interface or through SNMP. This read-only field shows the owner of the current sFlow configuration and assumes values as follows: • If sFlow is currently unconfigured/unclaimed, Owner contains . • If sFlow is currently configured through Web or CLI, Owner contains . • If sFlow is currently configured via SNMP, Owner contains a string identifying the sFlow receiver. If sFlow is configured via SNMP, all controls - except for the Release button - are disabled to avoid inadvertent reconfiguration. The Release button allows for releasing the current owner and disable sFlow sampling. The button is disabled if sFlow is currently unclaimed. If configured through SNMP, the release must be confirmed (a confirmation request will display). IP Address/Hostname : The IP address or hostname of the sFlow receiver. Both IPv4 and IPv6 addresses are supported. UDP Port : The UDP port on which the sFlow receiver listens to sFlow datagrams. If set to 0 (zero), the default port (6343) is used. Timeout : The number of seconds remaining before sampling stops and the current sFlow owner is released. While active, the current time left can be updated with a click on the Refresh button. If locally managed, the timeout can be changed on the fly without affecting any other settings. Max. Datagram Size : The maximum number of data bytes that can be sent in a single sample datagram. This should be set to a value that avoids fragmentation of the sFlow datagrams. Valid range is 200 to 1468 bytes with default being 1400 bytes. Port Configuration Port : The port number for which the configuration below applies. Flow Sampler Enabled : Enables/disables flow sampling on this port. Flow Sampler Sampling Rate : The statistical sampling rate for packet sampling. Set to N to sample on average 1/Nth of the packets transmitted/received on the port. Not all sampling rates are achievable. If an unsupported sampling rate is requested, the switch will automatically adjust it to the closest achievable. This will be reported back in this field. Valid range is 1 - 4294967295. Flow Sampler Max. Header : The maximum number of bytes that should be copied from a sampled packet to the sFlow datagram. Valid range is 14 - 200 bytes; the default is 128 bytes. If the maximum datagram size does not take into account the maximum header size, samples may be dropped. 33763 Rev.

Parameter descriptions
:
Agent Configuration
IP Address
: The IP address used as Agent IP address in sFlow datagrams. It serves as a unique key that will
identify this agent over extended periods of time. Both IPv4 and IPv6 addresses are supported.
Receiver Configuration
Owner
: Basically, sFlow can be configured in two ways: through local management using the Web or CLI
interface or through SNMP. This read-only field shows the owner of the current sFlow configuration and assumes
values as follows:
If sFlow is currently unconfigured/unclaimed, Owner contains <
none
>.
If sFlow is currently configured through Web or CLI, Owner contains <
Configured through local
management
>.
If sFlow is currently configured via SNMP, Owner contains a string identifying the sFlow receiver.
If sFlow is configured via SNMP, all controls - except for the Release button - are disabled to avoid
inadvertent reconfiguration.
The
Release
button allows for releasing the current owner and disable sFlow sampling. The button is disabled if
sFlow is currently unclaimed. If configured through SNMP, the release must be confirmed (a confirmation request
will display).
IP Address/Hostname
: The IP address or hostname of the sFlow receiver. Both IPv4 and IPv6 addresses are
supported.
UDP Port
: The UDP port on which the sFlow receiver listens to sFlow datagrams. If set to 0 (zero), the default
port (6343) is used.
Timeout
: The number of seconds remaining before sampling stops and the current sFlow owner is released.
While active, the current time left can be updated with a click on the Refresh button. If locally managed, the
timeout can be changed on the fly without affecting any other settings.
Max. Datagram Size
: The maximum number of data bytes that can be sent in a single sample datagram. This
should be set to a value that avoids fragmentation of the sFlow datagrams. Valid range is 200 to 1468 bytes with
default being 1400 bytes.
Port Configuration
Port
: The port number for which the configuration below applies.
Flow Sampler Enabled
: Enables/disables flow sampling on this port.
Flow Sampler Sampling Rate
: The statistical sampling rate for packet sampling. Set to N to sample on average
1/Nth of the packets transmitted/received on the port. Not all sampling rates are achievable. If an unsupported
sampling rate is requested, the switch will automatically adjust it to the closest achievable. This will be reported
back in this field. Valid range is 1 - 4294967295.
Flow Sampler Max. Header
: The maximum number of bytes that should be copied from a sampled packet to the
sFlow datagram. Valid range is 14 - 200 bytes; the default is 128 bytes. If the maximum datagram size does not
take into account the maximum header size, samples may be dropped.
