Port 161 is used by network management stations to issue queries to devices, while port 162 is used by devices to send unsolicited updates to the management stations.
This explanation is correct because SNMP operation involves a managing station sending requests via port 161 to gather information from network devices. The devices then respond with the requested data using the same port. Additionally, when devices need to send trap messages, which are essentially notifications for certain events or changes, they use port 162 to transmit these unsolicited updates back to the management station.
