SNMP Issue

[gnoc]

I am facing issues with SNMP, NMS server is unable to add the switches while check the switch logs i am getting below errors.

May  1 15:47:35  UKPKRPRDASW02 snmpd[1386]: SNMPD_AUTH_FAILURE: agent_io_reader: failed input interface authorization from 10.132.17.18 to 10.193.42.195 (3)

Where as other devices are working fine with the same configuration.

Hi gnoc,

Try to remove and to reapply the firewall filter at the interface where your SNMP request has being directed.

hi gnoc,

please look if you have snmp requests restricted to interface list. If the requests come from non-listed interface you will get the error log:

admin@EX2# show snmp 
interface ge-0/0/0.0;    <<<<<<<
community XXXXX {
    authorization read-only;
    clients {
        10.1.2.3/32;
    }
}

Jul  4 10:30:07  EX2 snmpd[987]: SNMPD_AUTH_FAILURE: agent_io_reader: failed input interface authorization from 10.y.y.y to 10.x.x.x (67)

 Remove/change the interface list under snmp.
