I posted this once already, but thought I might have more success here.

I have Redundant WAN's, I want track the availability of both from the Core Nexus 7K, if either WAN is Lost, I want to apply a Service Policy that will remark Video Traffic to DSCP 10. I have the following.

track 120 ip route 10.223.0.120/30 reachability  {the CE to PE link on Wan1}

track 124 ip route 10.223.0.124/30 reachability  {the CE to PE link on Wan2}

track 401 list boolean and

  object 120

  object 124

class-map type qos match-all VIDEO

  match dscp 34

policy-map type qos VIDEO_STOP

  class VIDEO

    set dscp 10

event manager applet VIDEO_STOP

  event track 401 state down

  action 1.0 cli command "enable"

  action 2.0 cli command "config t"

  action 3.0 cli command "int e8/23"

  action 4.0 cli command "service-policy output VIDEO_STOP"

  action 5.0 cli command "int e8/24"

  action 6.0 cli command "service-policy output VIDEO_STOP"

  action 7.0 cli command "end"

labCDCNX1-CS1# sh event manager policy internal VIDEO_STOP

                          Name : VIDEO_STOP   

                   Policy Type : applet

           Event Specification : event track 401 state down

                        Action : 1.0,vsh,sup:command "enable";2.0,vsh,sup:comman

d "config t";3.0,vsh,sup:command "int e8/23";4.0,vsh,sup:command "service-policy

output VIDEO_STOP";5.0,vsh,sup:command "int e8/24";6.0,vsh,sup:command "service

-policy output VIDEO_STOP";7.0,vsh,sup:command "end"

Event Specification active on : Standby, Active

labCDCNX1-CS1#

But when I meet the tracking criteria, the policy-map is not appied, I plan to do the reverse when the Track 401 state returns to UP

Thanks

[Joe Clarke]

Do you see the tracked object 401 going down?  The way it's written, it will go down if either the route 120 or the route 124 goes down.

NX-OS EEM is a different beast that IOS EEM.  I do not think you need "enable" with NX-OS applets.

[mcarlton62]

Yes the tracking function is working correctly,

labCDCNX1-CS1# sh track
Track 120
  IP Route 10.223.0.120/30 Reachability
  Reachability is DOWN
  12 changes, last change 00:01:30
  Tracked by:
    Track List  401

Track 124
  IP Route 10.223.0.124/30 Reachability
  Reachability is DOWN
  12 changes, last change 00:01:30
  Tracked by:
    Track List  401

Track 401
  List  Boolean and
  Boolean and is DOWN
  12 changes, last change 00:01:30
  Track List Members:
  object 124 DOWN
  object 120 DOWN

I remove the enable command but it still does't run properly, the debug isn't much help,

What is "No validation for vsh commands "?

[mcarlton62]

I was able to fix this the IOS Syntax is different than NXOS syntax

I have

event manager applet VIDEO_STOP
  event track 401 state down
  action 1.0 cli config t
  action 2.0 cli int e8/23
  action 3.0 cli service-policy output VIDEO_STOP
  action 4.0 cli int e8/24
  action 5.0 cli service-policy output VIDEO_STOP
  action 6.0 cli end

and it now works

[Joe Clarke]

Heh.  I'm so used to the IOS syntax, I missed the errant "command" keyword.  Thanks for the follow-up.  Glad it's working for you.
