wfOspfIfRtrDeadInterval
Module: RFC7777-MIB
OID (symbolic): RFC7777-MIB::wfOspfIfRtrDeadInterval
OID (numeric): 1.3.6.1.4.1.18.3.5.3.2.3.5.1.12
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: 'The number of seconds that a router's Hello packets have not been seen before it's neighbors declare the router down. This should be some multiple of the Hello interval. This value must be the same for all routers attached to a common network.'
What is wfOspfIfRtrDeadInterval?
This read-write value is the number of seconds of silence on this interface before neighbors declare the router down, normally set to a multiple of the Hello interval and required to match across all routers on the same network. A mismatch between neighbors here is a common cause of flapping OSPF adjacencies.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.2.3.5.1.12 snmpwalk -v2c -c public <target> RFC7777-MIB::wfOspfIfRtrDeadInterval
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.2.3.5.1.12.1 snmpget -v2c -c public <target> RFC7777-MIB::wfOspfIfRtrDeadInterval.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.18.3.5.3.2.3.5.1.12.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> wfOspfIfRtrDeadInterval.1
Start monitoring legacy Wellfleet/Bay Networks routers (OSPF configuration, filename coincides with unrelated later RFC) with a free 30-day trial of IPNetwork Monitor. Create custom SNMP monitor using the RFC7777-MIB::wfOspfIfRtrDeadInterval OID value, configure state conditions and alerts, and monitor any legacy Wellfleet/Bay Networks routers (OSPF configuration, filename coincides with unrelated later RFC) from a single console.
