Hi,I'm wondering how bandwidth can be "reserved" in a LLQ. For example, say I build the following policy map that puts voice traffic in a LLQ and also reserves 20% of a circuit's bandwidth:policy-map QUEUE_SERVICE_EGRESS class VOICE_EF priority perc...
Hi,In QoS, voice traffic is usually marked EF and placed in a priority queue. But interactive video traffic, like VTC, should also receive priority treatment. Can I put both classes in their own priority queues in the same policy map? I thought there...
Hi,When using the priority percent and bandwidth percent commands in a QoS policy-map, the priority percent option reserves a certain percentage of an interface's bandwidth, but also limits it to that bandwidth. Any of that priority traffic that exce...
Hi,I'm designing a QoS implementation and I'm going to use class-maps and policy-maps and service-policy commands. Now, obviously you use these commands to classify different kinds of traffic and define how you want it handled. But I'm confused about...
Hello,We recently purchased a Cisco ASR1002 router with four on-board Gigabit SFP-style Ethernet ports. However, when I do a "show ip interface brief", I see that there's an extra Gigabit Ethernet port. See the last interface in the following output:...
I already got an answer to this question: The priority percent syntax is misleading, because it's similar to the bandwidth percent syntax. But with the priority queue, traffic is not reserved, but rather capped at that percentage. That's because prio...
I see! That makes sense.So, as a follow-up, how would we "prioritize" amongst other classes of traffic? This occurred to me when I was reading about the Mission-Critical and Best Effort classes (as defined by Cisco's QoS baseline). Presumably you wou...
I was speaking with a fellow engineer and he was telling me that it was basically because you couldn't have a priority queue coupled with an unbounded access to bandwidth, otherwise traffic in that class could potentially starve the other traffic. I ...
