TRACK-6-STATE: 1 ip sla 1 state Down random flood

[Kgrevemberg]

Hi,

I have a cisco 4900 in our network that will periodically flood this altert:

TRACK-6-STATE: 1 ip sla 1 state Up -> Down

TRACK-6-STATE: 1 ip sla 1 state Down -> Up

I have no context for why it does this and have no idea what it could be talking about.

Can anyone guide me to what I should be looking for for this?

Any help is greatly appreciated.

The device  might have configured to monitor with IP Sla tracking.

show us the more running configuration so we can guide you best.

By default the settings are different - based on your configuration we can tweak with more delay.

So I'm unable to post full configs but I can say that it has this:

ip sla 1

  icmp-echo x.x.219.10 source-ip x.x.218.1

  frequency 10

ip sla schedule 1 life forever start-time now

ip sla 2

  icmp-echo x.x.218.10 source-ip x.x.129.1

  frequency 10 

ip sla schedule 2 life forever start-time now

So is it that just periodically it can not ping the context for "ip sla 1"?

It shows up then down about 15-20 times real quick.

Hello

Basically the tracking isnt detecting icmp-echo response from x.x.219.10. via ip sla 1
You need to find out what that destination ip is and what that track is being applied to, it maybe that this is ghost config you don't need but you need to determine that.

show ip sla statistics
show track

Thanks for your help!

I've tracked it down to the port and what device it is. Waiting for that SA to come in to check it with him just ot be sure. I have a feeling this is an old config and not necessary to be monitored like this anymore due to changes.

I will use your commands though to check further into it for my own knowledge though. Thanks

So I can't really pin down why the SLA is triggering like this. The link to the device, which is 10 ft from the router, seems to be fine. 

#Show Track

ip sla 1 state up

state is up

Hello

By the looks of it that track isn’t applied to anything as you would see whats it’s tracking in the output of show track

Quite positive you be able to remove track 1 and ip sla 1 configuration

So is it that just periodically it can not ping the context for "ip sla 1"? >  Yes, sometimes you are losting conectivity with address, but if dont use it, you wont have problem.

You can disable it, if isn't necessary for you, you can use command below:

no ip sla 1

It shows up then down about 15-20 times real quick.
