AS400 systems listen for SNMP get requests on port 161 but they respond to the requestor on a random ephemeral port above 5000. This is true for all versions up to i6.1 at least.
Can SNMP listen for an SNMP response on a different port from the one it used to issue the SNMP get request? If so, how is this adjusted inside the product?
Thanks for your attention to this question.
