Nexus 5000 SNMP traps for failed FEX PSU's

ametcalf · ‎08-02-2013

If entity traps are enabled, will the failure of a PSU in a FEX (with 2 PSU's) result in a trap being sent or are the entity traps only for the 5000 rather than the 2000.

Reason for asking:I have a number of failed PSU's in FEX's which might have been a failed since power on and therefore have never transitioned from working to failing to send a trap. The FEX itself is constantly complaining of voltage issues

Hello Andy,

Do you receive SNMP traps for other events ? any special config like SNMPv3 / authentication etc ?

I have not tested in lab. Is it possible for you to check " cefcFRUPowerStatusEntry " / 1.3.6.1.4.1.9.9.117.1.1.2.1.2.471 OID ?

or do snmp walk for 1.3.6.1.4.1.9.9.117.1.1.2.1 ?

Padma,

Thanks for your response, we do get snmp traps from these switches, I tested that with a "test pfm snmp test-trap powersupply" and the trap was received, There is no special snmp configuration. The OID you are requesting returns a different value for each of our two 5010 switches

switch A= SNMPv2-SMI::enterprises.9.9.117.1.1.2.1.3.471 = INTEGER: 1087

switch B= SNMPv2-SMI::enterprises.9.9.117.1.1.2.1.3.471 = INTEGER: 1018

In both switches entity traps are enabled

entity : entity_mib_change Yes

entity : entity_module_status_change Yes

entity : entity_power_status_change Yes

entity : entity_module_inserted Yes

entity : entity_module_removed Yes

entity : entity_unrecognised_module Yes

entity : entity_fan_status_change Yes

entity : entity_power_out_change Yes

I notice your OID references "FRU" and I see a hidden extension to the snmp-server enable trap command

hidden-nameB(config)# snmp-server enable trap entity ?

entity_fan_status_change Entity Fan Status Change

entity_mib_change Entity MIB change

entity_module_inserted Entity Module Inserted

entity_module_removed Entity Module Removed

entity_module_status_change Entity Module Status Change

entity_power_out_change Entity Power Out Change

entity_power_status_change Entity Power Status Change

entity_unrecognised_module Entity Unrecognised Module

hidden-nameB(config)# snmp-server enable trap entity fru

hidden-nameB(config)#

I would be interested to see if this FRU was required yet hidden.

SW version system: version 5.0(3)N2(2)

5.1(3) does not have the fru command option. The command is snmp_server enable traps entity entity_power_status_change.

I don't believe this is turned on by default, but I cannot find any documentation that says this command is not enabled by default with the snmp-server enable traps command.

I also do not see any documentation that states this command will notify us of a Nexus 2000 power supply failure. Please advise.
