wfOspfMtuSize
Module: Wellfleet-OSPF-MIB
OID (symbolic): Wellfleet-OSPF-MIB::wfOspfMtuSize
OID (numeric): 1.3.6.1.4.1.18.3.5.3.2.3.5.1.29
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Configure MTU size per OSPF interface This parameter has the following values/meanings:
1 - Use the MTU specified by IP 2 - Use the MTU of ethernet, regardless of what IP says > 2 - Use this value as the actual MTU. If the value is smaller than what OSPF needs as a minimum then the mtu specified by IP is used. For example, 3 would never be used as an MTU.
What is wfOspfMtuSize?
Sets the MTU value OSPF advertises for this interface: 1 uses whatever MTU IP itself reports, 2 forces the standard Ethernet MTU of 1500 regardless of IP's value, and any value above 2 is used directly as the advertised MTU (falling back to IP's MTU if it's smaller than OSPF's minimum requirement). Admins use an explicit value here to work around MTU mismatches that would otherwise block adjacency formation during database description exchange.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.2.3.5.1.29 snmpwalk -v2c -c public <target> Wellfleet-OSPF-MIB::wfOspfMtuSize
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.2.3.5.1.29.1 snmpget -v2c -c public <target> Wellfleet-OSPF-MIB::wfOspfMtuSize.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.18.3.5.3.2.3.5.1.29.1 i <value>
