It depends on what you mean by managing them. If you want to see port status for these L3 devices, then PSM in ITSA v1.3 can be configured to do so. If you want see them connected in Layer 2 views, then they will only be attached to L2 devices (switches). L3 devices will only be shown as devices connected to L2 devices, not as the switch device with devices connected to it. For instance, in the Layer 2 Report, you will not see the L3 device in the left hand side of the output with other devices connected to it.
What are you suggesting then? How do i make those switches manageable through Switch Analyzer?
The Layer-2 Status of all devices should be set to "unset" initially (blue). They will not have a value other than unset until a Vendor (V) event has been issued for each device.
You stated that the whole topology is disturbed when you set the L3 devices as BH, but in what way? If an L3 device is set as BH in the oid_to_type, but it is actually a router, then it will be a router. (Where a router is a device with IP forwarding set to TRUE and / or has multiple IP interfaces.)

We are using NetView 7.1.4 FP3 on windows with Switch analyzer. We have three Enterasys Layer-3 switches. Two of them are running in router mode and one is working on Layer2 only but has Layer-3 IOS installed. In the initial discovery of the network the devices were not discovered properly (they were in BadOID smartset) i manually edited the oid_to_type and oid_to_sym files to fix the problem.
Now the problem is the Layer-2 Status of these devices is set to "unset" when i run ovtopodump-X command, and in the IP MAP the Layer-2 status is "Unset or unknown" (Blued). What should i do to make them managable with Switch Analyzer? When i forcefully set the object type to switch (BH). Then the whole topology is disturbed. Any suggestions on how to FIX this?
Thanks in advance!
