Referencing a port adapte what?

goasakawa

Im very confused w/ port references like 0/1, 0/2 or 0/1/1. I kind of understand , I think, but i have no cisco lab and am having a hard time Visualizing it.....

...is this even going to be on the test?

It's an ID mechanisim basically designed to uniquely identify every interface on a router. the slot/port number style is found in modular routers while fixed config only have an increment going on for each type of interface.

the 0/1.1 is called a subinterface. you'll use subinterfaces when you starting doing things like inter-vlan routing, frame-relay, etc.

It's all a numbering system after all.

Take this link and look at the bottom picture. There are the two ethernet ports to the right in which is labeled 0/0 and 0/1. and then there is a slot on the left. What if you put a two ethernet port module in that slot... how would you be able to determin the difference?

The integrated ethernet ports would be labeled 0/0 and 0/1 while the module ethernet ports would be 1/0 and 1/1. As in slot 1 / port 0 and slot 1 / port 1.

Does that help?
