Resolved! CRC Errors
hi All,I am seeing a very high rate of input errors and crc errors on one of my fast interfaces used for metro e. can this cause a significant slow down in performance? i read online that this could be caused from a duplex mismatch. should I check...
Hello, everyone. I am currently studying QoS for my ENCOR exam and currently I am configuring classes and queuing. I understand that CBWFQ is a queuing algorithm where we can define our classes, create queues for them, and guarantee each one a minimu...
Hello. I've studied the multicast theory. But now I'm tasked with putting it into practice. I could guess here, but It's smartest if I humbly ask for some guidance, please... I need to architect a PIM SSM environment. QUESTION: Does it matter in what...
Resolved! Questions regarding IPP and QoS Markings
Hello, everyone. I have a few questions regarding QoS. With IPP, a lot of my resources say that values 6 and 7 are reserved. However, there doesn’t seem to be anything preventing me from using 6 and 7 in IPP to mark my traffic Why are packets like O...
Hello, everyone. I understand what WRED is and what it does. I understand that once we exceed a certain threshold, it will start randomly dropping packets. I also understand that since it's weighted RED, it can be more strict towards low-priority tra...

Hello, everyone. I've read that an LLQ can starve out other queues. So for this reason, we can set a limit on it so anything exceeding this limit can be dropped or put to the normal queues. However, I don't quite understand how limiting the LLQ can p...
Hello, everyone. I am studying QoS for my ENCOR exam and my study resources mention LLQ and policing. With LLQs, if we don’t define a policing limit, the LLQ could starve out the other queues if it’s constantly receiving a stream of VOIP packets, cor...
Hi,We have an simple tcl script as an event manager policy.A new AAA design results in not enough privaleges for running this.We can avoid this to create some new AAA authorizations lists, but I was wondering if i run this script as an system type, i...
Resolved! Bandwidth versus Speed
I am currently studying QoS and I am often confused and tend to mix the terms "Bandwidth" and "Speed". If I am not mistaken, bandwidth is the capacity of the link, correct? While the speed defines how fast the data is transmitted? If that's the case,...
Resolved! QoS behaviour during congestion
Hello, everyone. If someone configures QoS classes and prioritizes different types of traffic and let’s say that they configure CBWFQ for any non-voice data and LLQ for voice data, these shouldn’t take effect unless the traffic amount exceeds the li...
