SNMP Trap if a FEX goes down

[mariohecker]

hello,

need some assistance or help. I have a Nexus 7009 with  a FEX N2K-C2248PQ connected. If the N2K goes down (e.g. power down) a syslog event is generated but no snmp-trap from the N7K to the snmp server. Interface up/downs or power supply failures are traped. This is the syslog event:

 2014 Feb 13 10:47:47.594 n7009 %FEX-2-NOHMS_ENV_FEX_OFFLINE: FEX-113 Off-line (Serial Number xxxxxxxxx)

is  there anybody with an idea?

We've found no solution out-of-the-box, even after some intense research.

But we implemented a simple workaround:  Embedded Event Manager Applet. (EEM)

event manager applet EM-CHECK-FEX
  description "Checks FEX for availability because no trap would be send"
  event syslog occurs 1 pattern "FEX-2-NOHMS_ENV_FEX_OFFLINE"
  action 100 snmp-trap strdata "FEX changed to OFFLINE"
  action 101 syslog priority notifications msg TRAP_SEND: FEX changed to OFFLINE

The EEM tracks the occurence of the specific syslog-pattern.

If the syslog-pattern in question appears, a snmp-trap will be send.
