snmpv3 failure

[mulhollandm57]

folks

i've moved from snmpv2 to snmpv3 and i'm no longer seeing any events on my snmp server

when i run a packet capture i can see my router sends a get-request to the snmp server

the snmp server, spectrum, then replies with a 'report' but i suspect with the wrong engineid - the router engine id ends in '4748'

can someone confirm if i'm correct or is there something else i'm missing

i've attached some wireshark screenshots

thanks to anyone taking the time to look at or respond to this - greatly appreciated

many thanks for your reply, it's greatly appreciated - I've pasted the sanitised config below

the nsm, 10.63.132.100, can poll the router using snmpv3, but if i change from v2 to v3 all traps stop working immediately

thanks for your help

for testing i use simple below:

snmp-server user balaji network-admin v3 auth sha Mysha priv aes-128 Privaes

check snmp user priv :

#show snmp user

Hello,

stupid question maybe, but have you set up an SNMPv3 user and trap receiver on the Spectrum ?
