Network advisor 12.1.3 SNMP communication failed

  • 1.  Network advisor 12.1.3 SNMP communication failed

    Posted 07-18-2014 05:57 AM

    Hi,

    I have Network advisor 12.1.3 installed and discovered multiple 6520 Switches .

     

    There is but one 6520 switch which throws an error Discovered: SNMP communication failed. SNMP credentials may be invalid.

    SNMP configuration is similar among all switches. Strange that Only one switch reports an error. Any help or experiences is appreciated.

     

    Switch where error is reported :

     

    PRIV0:FID10:adm_user1> snmpconfig --show snmpv3
    SNMP Informs = 0 (OFF)
    SNMPv3 USM configuration:
    User 1 (rw): snmpadmin1
    Auth Protocol: noAuth
    Priv Protocol: noPriv
    User 2 (rw): snmpadmin2
    Auth Protocol: noAuth
    Priv Protocol: noPriv
    User 3 (rw): snmpadmin3
    Auth Protocol: noAuth
    Priv Protocol: noPriv
    User 4 (ro): snmpuser1
    Auth Protocol: noAuth
    Priv Protocol: noPriv
    User 5 (ro): snmpuser2
    Auth Protocol: noAuth
    Priv Protocol: noPriv
    User 6 (ro): admin
    Auth Protocol: noAuth
    Priv Protocol: noPriv
    SNMPv3 Trap configuration:
    Trap Entry 1: No trap recipient configured yet
    Trap Entry 2: No trap recipient configured yet
    Trap Entry 3: No trap recipient configured yet
    Trap Entry 4: No trap recipient configured yet
    Trap Entry 5: No trap recipient configured yet
    Trap Entry 6: 10.251.0.24
    Trap Port: 162
    Trap User: admin
    Trap recipient Severity level: 4

     

    Other switch where it works :


    PRIV1:FID11:adm_user1> snmpconfig --show snmpv3
    SNMP Informs = 0 (OFF)
    SNMPv3 USM configuration:
    User 1 (rw): snmpadmin1
    Auth Protocol: noAuth
    Priv Protocol: noPriv
    User 2 (rw): snmpadmin2
    Auth Protocol: noAuth
    Priv Protocol: noPriv
    User 3 (rw): snmpadmin3
    Auth Protocol: noAuth
    Priv Protocol: noPriv
    User 4 (ro): snmpuser1
    Auth Protocol: noAuth
    Priv Protocol: noPriv
    User 5 (ro): snmpuser2
    Auth Protocol: noAuth
    Priv Protocol: noPriv
    User 6 (ro): admin
    Auth Protocol: noAuth
    Priv Protocol: noPriv
    SNMPv3 Trap configuration:
    Trap Entry 1: No trap recipient configured yet
    Trap Entry 2: No trap recipient configured yet
    Trap Entry 3: No trap recipient configured yet
    Trap Entry 4: No trap recipient configured yet
    Trap Entry 5: No trap recipient configured yet
    Trap Entry 6: 10.251.0.24
    Trap Port: 162
    Trap User: admin
    Trap recipient Severity level: 4


    Cheers,

    hi,

     

    what credentials did you use to discover that switch?

     

    rgds

    Hi,

     

    I used adm_user1 to discover the switch.

    hi,

     

    you also have to specify an SNMPv3 user during discovery. which one did you use there?

     

    On the other hand, if you discovered it in AUTO, try change it to manual and use one of the predefined users in the discovery process.

    Try to add the Network advisor server ip address in the access control list for SNMP on each switch.

    I added with read only permission and all the errors gone away after few minutes
