Hello Experts! Good Day, everyone. I've been trying to understand the BGP attributes but I'm having hard time understanding some areas of each attributes. Main issue is what will be the best suited attribute to use in an inbound traffic coming from ...
Hello everyone, this is my lab exercise where I have to configure the STP topologies to match the given diagram. Just wondering out of 12 topologies how many of them are possible to be done? I am only able to configure 3 of them.
Hi,I have issues with my eigrp adjacancy between two routers. When I checked the eigrp neighbors, it only showed up in one router (R3). I could see below logs in the R3 router: router3#show ip eigrp neighborsEIGRP-IPv4 Neighbors for AS(1)H Address In...
We are working on getting authenticated scans working from our Risk department to determine to gather more information to eliminate some false positives as well as PCI requirements for authenticated scans. We are working with the Vendor (Qualys) on ...
Hello ladies and gents, This might be an easy question for some of you, but I am still trying to see the benefit of dynamic Etherchannel configuration over static configuration. The amount of line commands are the same as shown in the example below, ...
Hello, I am using Packet tracer and I have a doubt, I know that a port-channel sets its mac address using the mac address of the first interface, my question is the next, How I can see the port-channel's mac-address? Is it the 1st mac address of the ...
Hello, everyone. When it comes to calculating the average queue depth for WRED, why is the formula designed this way? If I had 45 packets in the queue and now I have 50, so average = 45 + (50 - 45), which is 50. Don't I already have the average que...
Hello, everyone. I am studying WRED from NetworkLessons.com and they have this graph I understand that WRED is a mechanism that drops packets but why is the queue depth meassured in packets? Why are we monitoring the amount of packets that are in t...
Hello, everyone. I have a quick question about how WRED drops traffic. Consider this example that I found on NetworkLessons.com IPP3 has the following values configured:Minimum Threshold: 20 packetsMaximum Threshold: 45 packetsMark-Probability Denom...
Hello, everyone. I understand that we configure classes to classify our traffic. Then, inside our policy maps, we can apply certain bandwidth reservations to them. Then, during the times of congestion, they have the guaranteed minimum bandwidth (max ...
I have a serial interface that goes up and then back down about every 30 seconds. Does anyone know of any debug commands that I can put on this sub interface to determine what could be causing this. I have 14 other remote locations workling fine. I a...
Hello, everyone. I understand what QoS groups are. The idea is that you can classify something in your input policy map and then apply a qos group to that packet so that when it gets routed out of the egress interface the egress policy map applies it...
Hello, everyone. When it comes to policing, there are policers that are known as dual-rate. This means that their operation is based off and can be adjusted by two values - CIR and PIR. I understand that packets that fall under or are equal to the CI...
