docsIetfQosUpstreamFragments
Module: DOCS-IETF-QOS-MIB
OID (symbolic): DOCS-IETF-QOS-MIB::docsIetfQosUpstreamFragments
OID (numeric): 1.3.6.1.2.1.127.1.5.1.2
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of fragmentation headers received on an upstream service flow, regardless of whether the fragment was correctly reassembled into a valid packet.
This counter's last discontinuity is the ifCounterDiscontinuityTime for the same ifIndex that indexes this object.
What is docsIetfQosUpstreamFragments?
Counts fragmentation headers received on this upstream flow's interface, regardless of whether the fragment was ever successfully reassembled. A high count relative to total packets suggests the modem is fragmenting frequently, often because upstream bursts are larger than the channel's grant sizes.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.127.1.5.1.2 snmpwalk -v2c -c public <target> DOCS-IETF-QOS-MIB::docsIetfQosUpstreamFragments
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.127.1.5.1.2.1 snmpget -v2c -c public <target> DOCS-IETF-QOS-MIB::docsIetfQosUpstreamFragments.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> docsIetfQosUpstreamFragments.1
