Unable to send SNMP Inform notifications form ERS4900 series

[BrunoE]

Hi,

I've configured SNMP v3 correctly on an ERS4900 series switch, all is working fine. I'm able to send traps v3 too. But I would test to send Informs instead of Traps: so I've configured this with this command:

snmp-server host v3 inform

and nothing is sent by the switch. What I'm doing wrong ?

Thanks for any advice.

This is the script that I have always used with no issues -

no password security
snmp-server enable
snmp-server user <Username1> sha <Authentication Key> aes <Privacy Key> read-view nncli notify-view nncli
snmp-server user <Username2> sha <Authentication Key> aes <Privacy Key> read-view nncli

default snmp-server host
snmp-server host <Trap Receiver IP> v3 authPriv <Username1>

no snmp-server community

no password security isn’t required, but if you do have password security turned on then you can't script it out in one line and will have to confirm the Keys as you enter them.

@Jean-Albert Vescovo I’m having similar problems setting up our ERS4900 and ERS5900 environment.  I don’t even seem to get the switch to send traps.

I can’t see what I am missing:

! *** SNMP ***
!
snmp-server name "switch-name"
snmp-server view v3write +1.3 +1.0.8802
! snmp-server user snmpuser md5 ******** des ********
! snmp-server user comns md5 ******** read-view nncli write-view v3write
! snmp-server community *************** notify-view acli

snmp-server notify-filter trap +org
! snmp-server host <ip-address> port 162 v2c  "community-name"

@Jean-Albert Vescovo This is worthy of a ticket.  If you have support you should open a case ASAP.

Hi Sean,

Sorry for this very late response. One year after, I’m still unable to send SNMP inform notification from our ERS4900 Series switches...so we were forced to use SNMP trap and declare SNMP engineID of each our switch into our snmptrapd.conf configuration file...
