SNMPv3 on Cisco devices

---This is my configuration for cisco device:
snmp-server group v3group v3 noauth read V3Read write V3Write
snmp-server user v3user v3group v3 auth md5 v3pass
snmp-server view V3Read iso included
snmp-server host 192.168.249.1 version 3 auth v3user
snmp-server enable traps

----This is the command that I use for snmpwalk:"snmpwalk -v3 -u v3user -l noauth -a md5 -A v3pass 172.17.50.250"

----This is the reponse of the snmpwalk from centos console and the command snmpwalk from the web zenoss interfaz:
