Issue

• We use snmp v2 trap to monitor the linkup/down of the network devices.
• We noticed that SNMPv2-MIB::snmpTrapEnterprise.0 variable was included in each trap. And, we know if there is a way to remove the variable from a trap. The following is a part of the tcpdump

• Also, when we ran "service snmpd reload", the following net-snmp specific trap was sent. We want to know if there is a way not to send such traps, since we want to monitor the trap only about linkup/down.
