SNMPV3 can not work on Cisco 72000

Cisco IOS Software, 7200 Software (C7200-ADVENTERPRISEK9-M), Version 15.2(4)M11, RELEASE SOFTWARE (fc2)

 

hi I'm trying to config and run SNMPv3 for first time I but it doesn't work. now I have an router on my lab and a server with multiple snmp manager apps and server can router my router directly so I wont have any security issue during this test. my configuration for snmp V3 is:

 

R1#show run | in snmp
snmp-server group v3group v3 auth read iso-view write iso-view notify iso-view
snmp-server group v3group v3 priv read iso-view write iso-view notify iso-view
snmp-server view iso-view iso included
snmp-server community rw RW
snmp-server location nanjing
snmp-server contact wangchong
snmp-server enable traps entity-sensor threshold
snmp-server host 192.168.10.254 version 3 priv cisco

 

here is the debugging:

findContextInfo: Authentication failed no local context exists for the Context Provided .
SrDoSnmp: authentication failure, Unknown Context.

 

As per above messages something missing in configuration, athhentication and Context.

Please post full configuration to look, also tell us how you doing snmpwalk command other side.
