I am not aware of a way to use OMNM to map out individual ports or to search for a device based on it's MAC address. You can go to visualize, which will display a topology of the network. Then click on data/node finder and it will list out the devices for you. You can then click on those devices and it will show you where they are located in the topology. Here is a video that demonstrates this capability some. www.doradosoftware.com/.../Visualize.html
hi I have a number of Dell PowerConnect switches (mostly 6248), along some Cisco devices spread out over two data centres. I'm looking to create some network diagrams of two data centres and am hoping someone can recommend a good piece of network mapping software that I can use to map out switches, routers and links.Im wondering if there is a HP Openview or 3com network director equivalent for Dell that   I can use with read only SNMP strings.  Please advise....  thanks
