SNMP Traps for hardware errors

[Ricky S]

Hi folks, was wandering if anyone can lend a quick hand with this one. We have a router that's been registering the following events in its local log:

Sep 30 09:32:27.212 EDT: %ENVMON-3-FAN_FAILED: Fan 1 not rotating

I have configured SNMP traps for link up/down on this router however nothing for a hardware error such as above. What SNMP trap can I enable that will allow my NMS to start receiving notification of all similar issues and events?

Thanks

Hi Ricky,

you can use this

snmp-server enable traps envmon fan shutdown supply temperature status

thanks

Hi Amrinder, this is what I have

ip access-list standard snmp_hosts

permit 172.18.120.241

deny   any

!

snmp-server community xxxx RO snmp_hosts

snmp-server community xxxx RW snmp_hosts

snmp-server trap-source GigabitEthernet0/1

snmp-server enable traps envmon fan statuschange

snmp-server host 172.18.120.241 version 2c xxxx envmon

snmp-server manager

!

I have checked the community strings and they match.

Interface GigabitEthernet0/1 can communicate with 172.18.120.241

However my end stations is still not seeing any traps coming from this router.

hello Ricky,

is there any access list blocking ip address for GigabitEthernet0/1 ?

try Show snmp and see if actually that’s running.

Add this to your snmp config

snmp-server enable traps 

(this ine enables the router to send Entity MIB notifications in addition 
 to any traps or informs previously enabled)

snmp-server host 172.18.120.241 public snmp envmon 

(replace public with you community string)

see if this make any difference .

thanks

After I punched in snmp-server enable traps, it enabled a lot of them

Thats when I also captured 2 traps at my NMS but not the ones I'm looking for i.e. Fan.

Please advise

Your show snmp information is not showing if these traps are enabled or not.

Check this example

Network#sh snmp

Chassis: XXXXXX

Contact: XXXXXX

Location: XXXXXX

   Logging to XXXXXXXXXXX, 0/10, 141134 sent, 76 dropped.

But other than that everything looks fine .

Please try this command again.
