    Not seeing any discovery traffic hit my switch

    I am trying to get auto discover for SNMP working. I configured a single switch with SNMP to make sure it worked then deleted its profile so it can get discovered and added automatically. My discovery sim I haveply checks for the 1.3.6.1.2.1.1.1 response. My action links the SNMP v2 template and adds the host to a group. I have debugging running on the switch so I can see when SNMP traffic hits it but none does. The discovery job has a 1m timer so it should go off frequently.

    Running this snmp walk from the Zabbix 5.2 host works as expected so it's not firewalls or connectivity problems.

    snmpwalk -v2c -c acme.lan.switch 10.1.1.250 1.3.6.1.2.1.1.1
    SNMPv2-MIB::sysDescr.0 = STRING: Cisco IOS Software, C3750 Software (C3750-IPSERVICES-M), Version 12.2(25)SEB4, RELEASE SOFTWARE (fc1)
