sFlow record formats

sFlow Datagram Header (SAP and port)

Datagram version

5

Agent Address

Active CPM IPv4 address (from BoF)

Sub-agent ID

0

Sequence number

CPM inserted sFlow datagram sequence number

SysUptime

SysUptime when the counters for records included in the datagram were collected by the line card

NumSamples

Number of counter records in the datagram

Counter header (SAP and Port)

Enterprise

0 (standard sFlow)

sFlow Sample Type

4 (Expanded counter sample)

Sample Length

sFlow packet size excluding header

Sequence number

Line card-inserted sequence number

Source ID Type

0

Source ID Index

tmnxPortId of the physical port (sFlow data source)

Counter records

Count of counter records in the datagram

Ethernet Interface Counters (EIC) – port (Ethernet Layer)

Enterprise

Statistics returned are based on dot3StatsEntry in EtherLike-MIB.mib. Statistics support may depend on hardware type.

Format

Flow data length

Alignment Errors

FCS Errors

Single Collision Frames

Multiple Collision Frames

SQE Test Errors

Deferred Transmissions

Late Collisions

Generic Interface Counters (GIC) – port/SAP

Enterprise

0 (standard sFlow)

Format

1 (GIC)

Flow data length

88

ifIndex

Port: ifIndex (tmnxPortId) of phys port

SAP: SapEncapValue - part of SAP SNMP key

ifType

Port: 6 (EthernetCsmacd)

SAP: 1 (Other)

ifSpeed

Port: Port speed value

SAP:

• top 32 bits: svcId for SAP (TIMETRA-SAP.mib)

• lower 32 bits: sapPortId (TIMETRA-SAP.mib)

The values plus ifIndex in the record are SAP SNMP key.

SapPortId is LAG’s tmnxPortId for SAPs on a LAG and port’s tmnxPortId for SAPs on physical port

ifDirection

Derived from MAU MIB (0 = unknown, 1 = full duplex, 2 = half duplex, 3 = in, 4 = out)

ifAdminStatus

0 (down) 1 (up)

ifOperStatus

0 (down) 1 (up)

Input Octets

Statistics return for port are based on ifEntry or ifXEntry in IF-MIB.mib as applicable.

Statistics returned for SAPs are sum of counters based on the sFlow ingress/egress counter map configured.

Input Packets

Input Multicast packets

Input Broadcast packets

Input Discarded packets

Input Errors

Statistics return for port are based on ifEntry or ifXEntry in IF-MIB.mib as applicable.

Statistics returned for SAPs are sum of counters based on the sFlow ingress/egress counter map configured.
