Hi - I'm demo the NCM and trying to add devices using the Detect Network Devices feature to add many devices. It says success, but it marks the devices as Non Active Nodes and they don't show up anywhere in NCM (that I can see).
When I use the add New Device wizard to add a single device, it works fine though. Anyone have an suggestions to get the Detect Network Devices working? I'll be back in the office at 8am pacific time if you have any suggestions. Thanks,
You can set the different encyrption (priv) levels for SNMPv3 when editing a device. If you look down in the Connection Settings you'll see this
Your problem is that you need the Encryption models to show up in the Device Password Rules, which Detect Network Devices would use. It's not there. You can do SNMPv3, but only DES encryption at that point...
So I see a couple options. First we need to realize that SNMP is only used in NCM for initial device discovery to get sysObjectID. The rest of the usage is mostly CLI (SSH/telnet) based commands like 'copy running-config tftp', etc. You COULD fall all the way back down to SNMP-initiated TFTP, but that's a last chance option.
So options are:
1) Enable SNMPv1/2c READ-ONLY on the device for discovery. You could put an ACL on the SNMP community and/or an SNMP view to restrict access to MIB-2 only objects.
2) Enable SNMPv3 with DES for a single user - that would be a 'discovery user'.
3) Forgo discovery and use Device Import. Maybe you have a gold list of devices from another product and you can get by running discovery.
