fethPortFrameTooLongs
Module: MODULES-MIB
OID (symbolic): MODULES-MIB::fethPortFrameTooLongs
OID (numeric): 1.3.6.1.4.1.81.12.6.1.1.1.18
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: This counter is incremented by one for each frame received on this port whose OctetCount is greater than maxFrameSize (Ref: 4.4.2.1, IEEE 802.3 Std). If fethPortFrameTooLongs is incremented then neither the fethPortAlignmentErrors nor the fethPortFCSErrors counter shall be incremented for the frame. REFERENCE Reference IEEE Draft Std 802.3u/D4 Rptr Mgt, 30.4.3.1.8, aFramesTooLong. Reference IETF 100Base-T Repeater MIB, rptr100MonitorPortFrameTooLongs.
What is fethPortFrameTooLongs?
Counts frames received on this port that exceeded the maximum legal frame size; the standard guarantees this counter and fethPortAlignmentErrors/fethPortFCSErrors are mutually exclusive per frame, so an admin seeing this counter climb knows it reflects oversized frames specifically, not garbled ones.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.81.12.6.1.1.1.18 snmpwalk -v2c -c public <target> MODULES-MIB::fethPortFrameTooLongs
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.81.12.6.1.1.1.18.1 snmpget -v2c -c public <target> MODULES-MIB::fethPortFrameTooLongs.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> fethPortFrameTooLongs.1
