This article describes the traffic flow of SNMP Queries traffic being sent only via the internal/management port under the following condition.
Problem or Goal
PCS device is not responding to SNMP Queries via internal port when management port is enabled (or) internal/management/external port is selected under System > Configuration > Advanced Networking > SNMP Traps
SNMP Queries & SNMP Traps are two different entities and Advance Networking Configuration option is only provisioned for SNMP Trap not for SNMP Query
SNMPD Process listens on SNMP Queries as below:
If the management port is enabled, then it listens on management port. If the management port is disabled, then it listens on internal port.
