wfIpv6BaseMinLinkMTU
Module: Wellfleet-IPV6-MIB
OID (symbolic): Wellfleet-IPV6-MIB::wfIpv6BaseMinLinkMTU
OID (numeric): 1.3.6.1.4.1.18.3.5.3.16.1.1.1.6
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This parameter indicates the minimum link MTU that is assumed for every link in the IPv6 internet. IPv6 specification defines this value to be 576 bytes, which is the default value of this attribute. By changing this parameter to other number it is possible to control the maximum size of packets that can be generated by this router if the Path MTU discovery is disabled.
What is wfIpv6BaseMinLinkMTU?
The minimum link MTU (296-65535 bytes) this router assumes exists on every link in the IPv6 network, defaulting to 576 as required by the base IPv6 spec. An admin would only need to touch this in a network with unusually large minimum-MTU guarantees, since routers/hosts rely on this floor when they haven't yet learned a larger Path MTU.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.16.1.1.1.6 snmpwalk -v2c -c public <target> Wellfleet-IPV6-MIB::wfIpv6BaseMinLinkMTU
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.16.1.1.1.6.1 snmpget -v2c -c public <target> Wellfleet-IPV6-MIB::wfIpv6BaseMinLinkMTU.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.18.3.5.3.16.1.1.1.6.1 i <value>
