How to copy a value of interface counter to a variable

[danilo.padula]

Hi Folks,

I'm new in EEM and I'm trying to read a interface counter and save the value in a new variable. I will use the new variable to manipulate the value.

Should I use SNMP (event snmp oid ...) to get the value?

It depends on the counter and how you want your policy to run.  What is the ultimate goal?

Hi Joseph,

I need to read the output packet counter.

We have a problem, that two routers 3845 stop forwarding without any reason.

We investigated with Cisco and didn´t find any BUG that explain the problem. So, I´m trying to make a applet in EEM to colect some commands to start the investigation.

So it's fair to say that if the output packet counter doesn't increase in a given time window you want to raise and event?  What should trigger this policy?

[danilo.padula]

Nothing it will trigger the event. We have to check the counter periodically. For example, one time per hour.

You can use something like this:

event manager applet periodic-cmds   

event timer watchdog time 60

action 1.0 cli command "enable"

action 2.0 cli command "show interface gi0/1 | append flash:/output.txt"

action 3.0 ...

Just keep adding the commands you want to run.
