Cisco router interface threshold

Hello,

 

I have a question about getting threshold information out of a specific interface. I have a customer with DSL on a cisco 887 router.

This customer has 2 different pvc's on the ATM0 interface, 2 dialer's (1 for voice, one for data) 2 vlan's (1 for voice, one for data).

 

What I would like is that the cisco router wil send me a message that only the voice dialer or voice vlan has exceeded it's threshold limit.

I can configure this with the "rmon alarm" command, but then it isn't specific for the voice dialer, it gives me info on both the dialers.

I also tried it with SNMP traps, but this isn't "real-time"

 

Does anyone know if there is a different solution to solve this?

Your applet doesn't have any

Your applet doesn't have any actions.  Add something like:

 

action 1.0 syslog msg "Threshold exceeded!"

 

So you can at least see if it's working.

You could use the interface

You could use the interface event detector to look at a specific interface.  Take a look at the help for "event interface" when configuring an "event manager applet".

Thank you Joseph, I found

Thank you Joseph, I found this page:

https://supportforums.cisco.com/document/117596/cisco-eem-basic-overview-and-sample-configurations

the problem is that i can't find the object id for certain interfaces. For example when I have an interface Dialer1 and Dialer2 or Vlan1 and Vlan2. What is the object ID of Dialer2 and Vlan2?

Can't seem to find any info about that.

You don't need object IDs for

You don't need object IDs for the interface event detector.  Look at http://www.cisco.com/c/en/us/td/docs/ios/netmgmt/configuration/guide/12_2sx/nm_12_2sx_book/nm_eem_policy_cli.html then search on page for "Interface Counter Event Detector".  You can match on the interface name and a slew of parameters, include load and bps.

Thanks Joseph, I configured

Thanks Joseph, I configured the applet like this:

event manager applet int-rate-test
event interface name Dialer2 entry-op gt entry-val 110 entry-type rate exit-op lt exit-val 50 exit-type rate average-factor 1 poll-interval 1 parameter receive_rate_bps

this way it should send an snmp trap when it reaches above 110kb and reaches below 50kb right?

I'm not receiving any SNMP messages regarding above config though. But I'm getting SNMP traps every 5min.

Do you know what i'm doing wrong?

Cisco Employee

The parameter you specified

The parameter you specified is bps, not kbps.  Multiply by 1000.

Sorry, small mistake :-)

Sorry, small mistake :-)

 

Heres my configuration:

event manager applet int-rate-test
 event interface name Dialer1 parameter receive_rate_bps entry-op gt entry-val 110000 entry-type rate exit-op lt exit-val 50000 exit-type rate average-factor 1 poll-interval 1

When I download something from the internet it only shows the interface bandwidth usage stats every 5min. I'm not getting any event messages to my Zenoss server that a threshold has been reached or anything like that.

I have attached a file with the results.

Try configuring: load

Try configuring:

 

load-interval 30

 

Under your interface.  This will get you down to 30 seconds of refresh.

Hi Joseph, Still no luck...

Hi Joseph,

 

Still no luck... still getting the same results.

What exactly do you have

What exactly do you have configured now, and what does show interface show when you think the applet should trigger?  Essentially, the applet will look at the same values as show interface.

Here's the total

Here's the total configuration of the cisco router. I added the show interface while it was doing nothing and while I was downloading.
