    SNMP on Netventa3448

    russiangodzilla New Member

      Hello,

       

      I am configuring SNMPv3 on the Netventa3448. For some reason I keep getting the "SNMP_SOURCE Authentication Failure". Please help and let me know what I am doing wrong.

       

      ip access-list standard snmp

        permit host 10.x.x.6

        deny   any log

      !

      snmp-server view "SolarwindRO" 0 included

      snmp-server view "SolarwindRW" 0 included

      snmp-server community SolarwindRO view SolarwindRO RO

      snmp-server community SolarwindRW view SolarwindRW RW

      snmp-server user SolAdmin SolarwindAdmin v3 auth sha "1234" priv des "1234" ip access-class snmp

      snmp-server user MinionOne SolarwindMinions v3 auth sha "1234" priv des "1234" ip access-class snmp

      snmp-server group SolarwindAdmin v3 priv write SolarwindRW

      snmp-server group SolarwindMinions v3 priv read SolarwindRO

          I have figured out the issue in terms of having a few bad sectors.

           

          My new problem currently is trying to figure out why it keeps dropping my packets. Still getting the authentication error.

           

          ip access-list standard snmp

            permit host 10.x.x.6

            deny   any log

          !

          snmp-server community SolarwindRO RO

          snmp-server community SolarwindRW RW

          snmp-server user SolAdmin SolarwindAdmin v3 auth sha "1234" priv des "1234"

          snmp-server user MinionOne SolarwindMinions v3 auth sha "1234" priv des "1234"

          snmp-server group SolarwindAdmin v3 priv read SolarwindRW write SolarwindRW

          snmp-server group SolarwindMinions v3 priv read SolarwindRO ip access-class snmp

           

          and debug snmp packets showed:
