Hello all, I am using the following basic topology to assist with the question: If I initiate a ping from the PC to 10.0.0.2 only two of the packets get returned. It looks like two are going via R1 and the other to go via R2 and get discarded. I ...

Hello all, The title explains most of it. There's two 48poe+ models of the C3850. One has 715w of power and the other 1100w. What would be the deciding factor between these? To me the 715w model would be sufficient as it provides 435w of PoE which...

Hello all, I have the following basic setup: In all of the training material that I have for my CCNA and any videos that I have watched, I have not seen anyone adding the OSPF interface subnet to their OSPF process. For some reason I can only get...

Hello all, Is anyone able to advise if there is a standard or recommended calculation for working out how much bandwidth/speed you need between two connected switches. For example a stack of 3 48 port gb switches to a another stack of 2 48 port gb ...

Hello all, I have been trying to get my head around the Cisco hierarchical model but am struggling slightly. I understand the basic concepts of the layers but not where all of your devices fit in (servers, firewalls, WAN connections etc). As an ex...

Hi Joseph, It could just be packet tracer as you say. I have had many issues with it that wouldn't happen in the real world. I haven't got a real lab to test with but am in the process of setting up GNS3 so may be able to test on there. For the te...

Hello, Thank you everyone for all of the responses. I have set this up in packet tracer to simulate. If I ping from PC1 to R3 at the top of the diagram, it follows this sequence: Packet 1: PC1 > R1 > R3 > R2, R2 drops the packet as the destinati...

Thanks again Reza, I wasn't implying that I intend to use a single power supply for the entire stack. I was talking about the very unlikely scenario that multiple power supplies fail within the stack. Regards Matt

Hi Reza, That helps. So I guess it just depends on the poe requirements. I've seen a demo of stack power where a single PSU held up the entire stack of three. This is a very unlikely scenario I guess but would a single 715w PSU be capable of this? ...

Thank you Rick, That makes complete sense and helps to clear things up. I was working on the basis that the network commands purpose was to define the network to advertise. With the combinations of your reply and cwhite's reply it now makes sense....
