snmp-agent trap enable

 

check the configuration from U2000

we found the authentication procotol is HMACSHA and the Encryption protocol is AES256


Root Cause

wrong configuration with SNMPV3 and encryption protocol


Solution

change the snmp configuration and the encryption protocol as bellow:

snmp-agent

snmp-agent local-engineid 800007DB0368CC6EADF190

snmp-agent sys-info version all

snmp-agent group v3 test privacy read-view iso-view write-view iso-view notify-view iso-view

snmp-agent target-host trap address udp-domain 1.1.1.1 source Vlanif2 params securitynameadmin v3 privacy

snmp-agent mib-view included iso-view iso (mib include the iso-view that we add in the read and write view)

snmp-agent usm-user v3 admin

snmp-agent usm-user v3 admin test (user need add to the group)

snmp-agent usm-user v3 admin authentication-mode sha cipher %^%#0a>h,T#5;+j`xAIXiZ!KUQvd.!1m^3e`--)K<.0~%^%#

snmp-agent usm-user v3admin privacy-mode aes256 cipher %^%#G}Ls53tWn7m[D/&_mD#@lrIl4Ff>B)6yu7-nU`_B%^%#

snmp-agent trap source Vlanif2

snmp-agent trap enable


Suggestions

when configuration the snmp with NMS servers need notice the snmp confiration especially the authentication procotol and the Encryption protocol.
