I have configured Cisco Catalyst 2950 L2 switches with the view oid-tree included, however, it appears that the LMS cannot read the chassis and identify as a switch and all the switch reports are invalid.
If there is another MIB view that I can use.
As I said in the other thread, SNMPv3 and 2950s don't mix. For full management capability, you need to stick with v1/v2c on these devices. Any device which can run 12.2 or higher code can make full use of SNMPv3.
