I am having a problem similar to:
I have Engineer's Toolset version 9.2.0.47. We have several Cisco 6513s as our core switches in different locations. Of the nine switches, I do not get the Device MACs/IP/DNS Name information on 5 of them - only 4 display the information in switchport mapper.
These switches share the same IOS, configs are the same, etc. They are all layer 3 devices.
I've searched this forum extensively, but don't see where there has been a definative fix.
Any ideas???
