I have a query from a colleague which I am unsure of the answer and I don't want to risk hardware damage by testing!
They are studying for CCNA and are wanting to do it on the cheap.
The query is, on a model that has two or more serial interfaces, are you able to plug a DTE to DCE cable between the two ports? IE on the same router plugging both serial interfaces to eachother.
Of course on one of the interfaces one would be configured with clocking etc, but would this kind of setup function for this type of learning?
Thanks heaps ! (I really don't want him to test and short circuit the router or anything :P )
