Folks, I am having a hard time trying to figure out why the G0/2 interface on CD1 switch becomes a blocking port, and the F0/21 becomes the DP. Thus making the F0/21the the blocking port on Acc4 switch. In this example, Acc3 is the root bridge, so al...
Folks, After configuring four routers with loopback0 192.168.0.6 - 192.168.0.9 respectively, Router 9 (loopback0 interface as 192.168.0.9 - highest loopback0 IP) is not becoming the DR. The priorities were not set, and was left as default 1. Also, co...
Folks, I am trying to understand when to use the command "area 0 range 10.0.0.0 0.0.255.255" instead of just the "network 10.0.0.0 0.0.255.255 area 0" with the topology shown below. The full commands are shown below, and I am trying to contrast both....
Hello folks, I have an issue with a Cisco 2960 port-security settings. I have enable port-security on the interface f0/3 with shut-down mode, and with a maximum of two MAC addresses. However, when I reach the maximum MAC limit, port-security does not...
Hello, I am trying to check the MAC address for the PO1 and validate that is using the MAC address of the first interface of the port-channel by using Georg Pauwen commands shown above. However, the MAC address of the PO1Switching, Catalyst 2000, LAN...
I thought it was an aggregated answer instead of a serial answer. Below are my answers. Good exercise. Root is switch A, all ports are FEsA: Thenall ports on Switch A are DPsB>A = RPC>A = RPB>C = Since the link have the same cost to the root, then it...
Didn't put this topology on PT, so I don't have the answer to your question before I've figured out. The answer is shown below. Color Coded: Green = Root PortRed = DPPink = Blocking Port
I got it now Joseph, and thank you again for the effort in trying to explain in order to make it clearer. Below is an edition of the main example provided in this thread, and I decided to change the G0/1 to F0/2, so all the links have the same cost t...
I think I finally got it, and you don't have to read all that is written below. This is just for resolution in case someone else gets the same question. However, my resolution was only possible thanks to all your explanations. So, thank you again for...
