Trying to add MAC Address to Network Printer Discovery

[Russ Hancock]

Hello,

I am trying to use Discovery (Helsinki) to discover Network Printers (using SNMP), but am not currently able to update the mac_address field on the cmdb.ci table.   I have added the following SNMP field to the "SNMP - Printing" probe and sensor, and the MAC Address is now being retrieved, but is still not being updated in the CMDB!   Can someone help?

Thanks

Hi Russell,

Not knowing your level of experience with Discovery or SN...We highly suggest that you do not modify OOB probes/sensors directly as this will impact future upgrades.   That said you could create a new exploration probe, add the SNMP Field that you have highlighted above and then create the appropriate sensor to parse the payload and set the mac_address attribute.

Or

Most likely the network adapter related list is being populated with IP/Mac already - you could create a Business Rule to copy the MAC from the cmdb_ci_network_adapter table to the main printer form.

Thanks Ryan!   Since I am successfully using a Discovery Identifier based on the MAC Address, I believe you are correct that the MAC Address must already be getting populated in the network adapter related list.   I like your idea of simply creating a business rule...   I will try that and post back!

FYI, since the OOB "SNMP - Classify" sensor is already returning the Network Printer MAC Address that I added above to "SNMP Printing", I went ahead and removed that change.   I have also already defined a business rule for the cmdb_ci table, which is where our "mac_address" field is stored (as opposed to the cmdb_ci_network_adapter table).   Our cmdb_ci_printer table is inheriting this attribute from cmdb_ci.   In my business rule script on the CMDB_CI table, I see that all the rest of the attributes I need are available, except for "current.mac_address".   When I look at the XML returned from the Discovery "SNMP - Classify" sensor, I see the MAC address I need, but for some reason it isn't getting updated on the CMDB_CI table!  

Any ideas?

Thanks!
