We have Netscout VSS Devices - SystemObject ID 220.127.116.11.4.1.21671
Spectrum is not able to Discover the Connections automatically
From the sniffer trace, we could see that Spectrum sends a get next request for iftype.1, ifspeed.1 ifphysaddress.1, ifdescr.1, ifalias.1 ifconnectorpresent.1 but the agent responds with iftype.1001, ifspeed.1001 ifphysaddress.1001, ifdescr.1001, ifalias.5 ifconnectorpresent.5 It should respond with the next entry in the table.
Release : 10.4
Component : Spectrum Core / SpectroSERVER
This is a confirmed Netscout Vendor issue - the devices run into an issue from running SNMPGetNext or SNMPBulkGet to query more than one MIB table.
Please reach out to Netscout to inquire when this issue may be resolved on the vendor side: https://my.netscout.com/Pages/overview.aspx
