Cisco QoS config w/ ASA 5510, Catalyst 3560, and 2960G
Posted on 2011-03-03
Hi Cisco Gurus,
Here's my current network config:
10x10MB internet connection <==> ASA 5510 <==> Catalyst 3560 48-Port Switch (LAN) <==> Catalyst 2960G (Servers)
I'm doing extensive research on implementing QoS to maximize my network bandwidth efficiency since I have many remote users doing file share, VPN, and VOIP while my LAN users require heavy internet and media streaming.
As I'm doing my research, I'm a bit confused on the following:
1) Do I need to set QoS Policies only on the ASA or on the ASA and switch(es) -- what's the best practice?
2) I'm unsure on how to calculate the following to configure:
a) For Priority Queing: tx-ring limit size & priority queue size - provide example for voip requiring 1000K worth of bandwidth
b) For Policing: Maximum Rate limit & Maximum burst size - provide example of restricting http/https traffic to max 50% of bandwidth
Please elaborate on how to calculate, cli command, and the rhyme and reason to it...thanks!
