wfIpv6IfCfgLinkMTU
Module: Wellfleet-IPV6-MIB
OID (symbolic): Wellfleet-IPV6-MIB::wfIpv6IfCfgLinkMTU
OID (numeric): 1.3.6.1.4.1.18.3.5.3.16.1.1.2.1.13
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The configured link MTU. It will be only considered if it is less than the default MTU of the underlying media. A value of zero indicates that the default MTU of the underlying media is to be used.
What is wfIpv6IfCfgLinkMTU?
The configured link MTU for this interface; it only takes effect if it's smaller than the underlying media's default MTU, and a value of 0 (the default) means 'just use the media's default'. An admin lowers this to force smaller IPv6 packets on a link with a lower real-world MTU than the interface type normally assumes, e.g. behind a tunnel with encapsulation overhead.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.16.1.1.2.1.13 snmpwalk -v2c -c public <target> Wellfleet-IPV6-MIB::wfIpv6IfCfgLinkMTU
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.16.1.1.2.1.13.1 snmpget -v2c -c public <target> Wellfleet-IPV6-MIB::wfIpv6IfCfgLinkMTU.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.18.3.5.3.16.1.1.2.1.13.1 i <value>
