wfIpv6IfStatsInTooBigErrors

Module: Wellfleet-IPV6-MIB

OID (symbolic): Wellfleet-IPV6-MIB::wfIpv6IfStatsInTooBigErrors

OID (numeric): 1.3.6.1.4.1.18.3.5.3.16.1.1.5.1.4

Node type: OBJECT-TYPE

Type: Counter

Access: read-only

Description: The number of input datagrams that could not be forwarded because their size exceeded the link MTU of outgoing interface.

What is wfIpv6IfStatsInTooBigErrors?

Count of inbound datagrams that couldn't be forwarded because their size exceeded the outgoing interface's link MTU. Persistent growth here suggests a Path MTU mismatch somewhere upstream that's triggering fragmentation problems (since IPv6 routers don't fragment in-flight).

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.16.1.1.5.1.4
snmpwalk -v2c -c public <target> Wellfleet-IPV6-MIB::wfIpv6IfStatsInTooBigErrors

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.16.1.1.5.1.4.1
snmpget -v2c -c public <target> Wellfleet-IPV6-MIB::wfIpv6IfStatsInTooBigErrors.1
