Good day everyone - i'm working on deploying QoS across our corporation and have a few questions - i'll keep it simple as for layout of network.
WAN(MPLS) -----(CERouter)----(OurRouter (2901)----(Switch(2960x)----devices (ip phone, desktop,etc..)
CE predefined QoS as follow marking so this is what they are expecting to receive as markings from me, which is fine.
how do i go about this?
1 - create ACL for all the traffic i want to mark and use policy-map
- if i use ACL wont the deny all at the end of ACL dropped the rest of the traffic?
2 - where do i apply ACL to SVI?phusical?
I been reading tones of info online but i can grasp around how it functions...
i'm a little confused how this comes together.
Hopefully i make sense...any help is appreciated. tks.
I think you can only understand QoS properly from the experts, not from the web - as I learnt myself.
I highly recommend this book by Odom Wendell on Cisco QoS, cheap second-hand too!
the ACL just needs to match what you want to prioritize (typically voice and video traffic), anything else goes in the default class.
Since you say your CE has QoS configured, can you find out what exactly is configured ?
Hi Georg - here are the markings; this is what they are expecting on their end from me - i guess my confusion is how do mark all this traffic coming in from LAN so that when it goes out WAN port its defined according? I gathered that each int would have an ACL filtering the traffic and classes marking traffic according to policy-map? thanks.
