This documentation supports the 21.3 (12.3) version of BMC Discovery.


Discovering IBMi

BMC Discovery enables SNMP discovery of IBMi (AS/400) targets. IBMi discovery consists of a UDP request from an ephemeral port on the appliance to port 161 on the target. The IBMi system responds using the same ephemeral port that initiated the request. BMC Discovery listens for a response on that port only.

IBMi discovery methods

IBMi (AS/400) discovery is undertaken using SNMP. SNMP discovery is supported for all devices with an accessible SNMP agent. Discovery supports SNMP v1, v2c, and v3. For some older platforms (Netware, for example) the use of SNMP v1 might be required. This requirement is defined on a per-credential basis. Only read (GET, GETNEXT, GETBULK) access is required.

This page shows the method used, the MIB values, and the OIDS used.
