configuring EEM on nexus 7K to receive alerts(Syslog msg) when packet(s) are dropped because of QoS

[kerim mohammed]

Hello,

I am trying to configure eem on nexus Cisco 7k switch which will generate syslog msg when  custom policy applied on interfaces kicks in and drops packets (one or more packets). here is the policer:

class-map type qos match-all GRID-NONLOCAL-DESTINATION
match access-group name GRID-NONLOCAL-DESTINATION
policy-map type qos GRID-NONLOCAL-DESTINATION-EGRESS-POLICE
class GRID-NONLOCAL-DESTINATION
police cir 1 gbps bc 200 ms conform set-dscp-transmit 0 violate drop

interface Ethernet3/3
service-policy type qos input GRID-NONLOCAL-DESTINATION-EGRESS-POLICE

I appreciate your quick reply.

thanks,

Kerim

[kerim mohammed]

Yes, alert email with packet drop count and associated policer.  high level is shown below (just need help with the details) or if there is a better approach.

action 1.0 syslog msg GRID policer kicked in, Y number of packets dropped on interface Ex/y

How would you determine this manually?  What version of NX-OS is this?
