VIP intermittent connectivity

k_sinjish — Thu, 17 Nov 2011 12:16:14 GMT

Hi All ,

We have faced a VIP outage in the load balancer.

When we are giving a continuous ping towards the VIP from outside it is facing the intermitted connectivity .

Some time can ping but other time we could not ping .It is not only for ICMP , for all traffic it is getting effected . For Eg SMTP , HTTPS .

We checked the configuration but could not see any failure…. All probs ,Rservers are up , and VIP is in INSERVICE .

But the resource usage shows as below

sh resource usage resource all

Attached with this .

Is there any chance the Denied traffic disturbed the traffic ? Or if any other trouble shooting step is there please suggest it .

Hi ,

Thanks for the update .

There were dropped connections . But i did not see whether it was increasing or not .

The real case was no outage of the VIP as well PROBE.

My question is will there be any resource related issue or anything elso which disturbes the communication .

So please suggest me if any other method of trouble shooting is there .

loadbalance:
        L7 loadbalance policy: XXX_XXXX_XXXX

        VIP Route Advertise : DISABLED
