Configuring EEM on n5k and n7k

[Nell_Ko]

Gretings community!

My client has two different nexus

  Nexus 5548 / 7.0(8)N1(1)

  Nexus 7710 / 6.2(16)

I was configuring EEM and faced a problem.

Before I open a case, I would like to make sure 

there is a solution to it.

configurations were

  event manager applet Link_Down_01

  event syslog pattern Interface Ethernet1/2 down

  action 1 syslog msg LINK_DOWN

it was working fine until I faced the following msg.

It says "Max Limit for syslog EEM events reached !!"

Does it mean that I can configure only few EEMs?

As for n5k, I was able to configure 10 EEM patterns

and as for n7k, I was able to configure 30 EEM patterns

I remember that I read a refrence which stated that nexus supports 500 EEM, but it seems that I can't.

Does that mean I can create 500 EEM but only few patterns?

-------------------------------------------------

Another problem is that EEM isn't working properly.

I'm not sure whether I missed something.

configurations were

  event manager applet Link_Down_01

  event syslog pattern Interface Ethernet1/2 down

  action 1 syslog msg LINK_DOWN

According to the configuration above,

when the Eth1/2 is down,

I'm suposed to receive a syslog "LINK_DOWN"

but I was only getting "Configured from vty by admin on vsh.#####"

If I change "action 1 syslog msg LINK_DOWN" to "action 1 syslog priority informational msg LINK_DOWN"

and when Eth1/2 is down,

I do get receive "LINK_DOWN" but also the "Configured from vty by admin on vsh.####"

Is this normal or an OS bug?

Hi
EEM syslog is limited to 10 in nx-os from memory
This action 1 syslog msg LINK_DOWN should be action 1 syslog msg "LINK_DOWN" if thats what your capturing in logs

Yes it could be a bug , this is from a 6k nx-os but same bugs can generally appear in each model as its can be unified software same style , you could confirm with TAC or check the release notes for that version see of the caveat is listed

Thanks!

It was an OS bug. I was had bit more of research just to make sure

and it is was a bug.

n5k and n7k has EEM limitation of 20~30.

I am not sure about the exact number but it was around 20~30.
