How to generate alerts if OSPF/EIGRP/BGP neighbor goes down?

Hi,

 

The major challenge we're facing as of now is that we're not able to monitor different routing protocols neighbour status. How to generate alert if my BGP status is showing down or my OSPF neighbor is showing dead?

Hi,

 

All these protocols can be monitored by enabling related traps routers. Also enable the specific trap parameter from NNMi incident configuration list.

Hi,

 

Below are the sample parameter through which you can monitor BGP/OSPF/HSRP state.

 

BGPBackward-> Transition Generated when the BGP Finite State Machine moves from a higher numbered state to a lower numbered state.
BGPEstablished-> Generated when the BGP Finite State Machine enters the ESTABLISHED state.

HSRPStateChange> Sent when an HSRP interface transitions to or from an Active or Standby state in a particular HSRP Group.

OSPFIfStateChange-> Signifies that there has been a change in the state of a nonvirtual OSPF interface.

Re: How to generate alerts if OSPF/EIGRP/BGP neighbor goes down?

here are the TRAPs for EIGRP ..

 

 

# cEigrpAuthFailureEvent NOTIFICATION-TYPE "This notification is sent when EIGRP MD5 authentication is enabled on any interface and peer adjacencies are formed, and any adjacencies go down as a result of an authentication failure."
   

    cEigrpRouteStuckInActive "This notification is sent when a route in the topology table is stuck in an active state.  During the query phase for a new route to a destination network, a route is described as being in the active state if when an           alternate path is actively being sought, no replies are received to normal queries or stuck-in-active queries."
 
All the best .

Re: How to generate alerts if OSPF/EIGRP/BGP neighbor goes down?

[ Edited ]

Can't we poll this?

 

Trap rate on NNM has increased a defined limit of 150 traps/sec which results in blocking of SNMP traps. Not recieving all SNMP traps on my NNM console.

 

Below is the error -

[Major]  Incoming trap rate is 496.9 traps/sec since 7/22/13 9:27 AM. All traps are blocked since 7/22/13 8:44 AM and will remain so until rate goes below 150 traps/sec.

 

How to increase this limit to 500 traps/sec?

Hi,

 

Incoming traps rate parameter is configurable, you can use nnmtrapsconfig.ovpl script to change the threshold.

 

For better performance, try to reduce the incoming trap rate.

Re: How to generate alerts if OSPF/EIGRP/BGP neighbor goes down?

it's recommended to increase the TRAP limit , as it will need so much processing and analysis ,

 

what is recommended to find out what are the noisy traps and try to avoid them .. u can follow the attached document that will explain TRAP MGMT in NNM and how NNM handle the TRAP ..

 

Let me know if it worked with you or not !

 

All the best .

Hi Mostafa,

 

I've increased the trap limit to 500 traps/sec but still traps are not visible.

Re: How to generate alerts if OSPF/EIGRP/BGP neighbor goes down?

are  you sure the Related SNMP TRAPs are enabled to be shown on the console ?!

 

for test use the trapdump command for the output .. from the Following Command ..

 

nnmtrapdump.ovpl -t > D:/trapdump.txt

 

see all the traps OID and check if they are enabled on NNM incident Configuration or not ?!

 

let me know the result ..

All the best .
