sFlowMaximumHeaderSize
Module: SFLOW-MIB
OID (symbolic): SFLOW-MIB::sFlowMaximumHeaderSize
OID (numeric): 1.3.6.1.4.1.4300.1.1.4.1.6
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: The maximum number of bytes that should be copied from a sampled packet. The agent may have an internal maximum and minimum permissible sizes. If an attempt is made to set this value outside the permissible range then the agent should adjust the value to the closest permissible value.
What is sFlowMaximumHeaderSize?
This read-write value sets the maximum number of bytes copied from each sampled packet, defaulting to 128, with the agent adjusting out-of-range requests to its nearest supported value. Admins raise or lower it to trade off between capturing enough packet header detail (e.g. VLAN tags, deeper protocol headers) and the bandwidth/storage cost of larger sFlow datagrams. For example, an admin increases sFlowMaximumHeaderSize to 256 to make sure MPLS or QinQ-tagged headers are fully captured in each sample.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4300.1.1.4.1.6 snmpwalk -v2c -c public <target> SFLOW-MIB::sFlowMaximumHeaderSize
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.4300.1.1.4.1.6.1 snmpget -v2c -c public <target> SFLOW-MIB::sFlowMaximumHeaderSize.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.4300.1.1.4.1.6.1 i <value>
