sFlowMaximumDatagramSize
Module: SFLOW-MIB
OID (symbolic): SFLOW-MIB::sFlowMaximumDatagramSize
OID (numeric): 1.3.6.1.4.1.4300.1.1.4.1.7
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: The maximum number of data bytes that can be sent in a single sample datagram. The manager should set this value to avoid fragmentation of the sFlow datagrams.
What is sFlowMaximumDatagramSize?
This read-write value sets the maximum number of data bytes sent in a single sFlow sample datagram, defaulting to 1400, chosen by the manager to avoid IP fragmentation of the exported sFlow packets. Admins tune it to match the network path's MTU so sFlow export traffic isn't needlessly fragmented and dropped. For example, an admin lowers sFlowMaximumDatagramSize to 1350 on a path that includes a GRE tunnel to keep sFlow datagrams from exceeding the tunnel's effective MTU.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4300.1.1.4.1.7 snmpwalk -v2c -c public <target> SFLOW-MIB::sFlowMaximumDatagramSize
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.4300.1.1.4.1.7.1 snmpget -v2c -c public <target> SFLOW-MIB::sFlowMaximumDatagramSize.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.4300.1.1.4.1.7.1 i <value>
