Ive been using LMS 2.6. I believe the following LMS 2.6 issues are resolved from what I can see....
DFM -no SNMP v3 encryption. (I believe this is now supported)
CAMpus map no HSRP support ( I believe this is now supported)
CAmpus map CDP (security issues). ( I believe 3.2 has OSPF for Layer 2 ?)
I noticed when you deployed configs on LMS 2.6 it would do a 'diff' first and this created problems in complext network -not sure if this is resolved yet?
Any other improvements new features? What are you guys finding the best features of the product?
DFM 3.2 does support SNMPv3 polling (but not traps). Campus doesn't support HSRP in the mapping sense. Campus is focused on layer 2 mapping. Campus still requires CDP, but Discovery (which is now part of Common Services) supports other protocols such as ping sweeps, ARP table lookups, routing table lookups, etc. to find new devices in the network.
Beyond that, LMS 3.2 includes a number of changes and improvements. The most noticeable is the Portal UI. The CiscoWorks Portal allows you to build dashboards to show off both dynamic and static data. These dashboards replace the static CiscoWorks Homepage.
There were also many improvements made in terms of baseline compliance support, the ability to track users in near real-time in User Tracking, support for VRF-lite networks, EnergyWise devices, more inventory custom report attributes, less client-sided Java in Campus Manager, and more. The individual product release notes will tell the whole tale.
If you have a spare machine, you can also install a 90-day eval of LMS 3.2, and see these features for yourself. The eval can be downloaded from http://www.cisco.com/go/lms .
