Hi All,
I have attached a current setup for my new site. im pretty new in QoS settings, so need some advise of the config to be set.
Basically, i have enable "Auto QoS" on the access switchports connecting to CISCO IP phones. But i need advise on what are the QoS settings to be configure for the following interfaces.
1) I'm running port channel between Access 1 n 2, same for Core 1 n Access 1, vice versa. I cant configure auto qos on etherchannel port, therefore what will be the preferred setup?
Based on what i have read, i will only need this 2 config.. Am i right?
A) mls QOS
B) on the etherchannel interface "mls qos trust cos" or "mls qos trust dscp"
2) Between the Core switches and the firewall will be layer 3, therefore i am assuming these 2 config settings will be needed on core switches. Am i right?
A) mls QoS
B) since it's layer 3, "mls qos trust dscp"
3) There are some questions i would like to ask..
A) Auto-Qos will mark the packets as DSCP or COS? from the generated config, i see only "mls qos trust cos"
B) Since there will be layer 3 involve when accessing to MPLS cloud, should i just stick with "mls qos trust dscp" be it layer 2 or layer 3 interfaces? (including port-channel - Qustion 1B)
4) Im using checkpoint firewall, for now, there isnt any QOS settings. so im just preparing the interface connecting between Core - Firewall by enabling "mls qos trust dscp".. Will the MPLS routers receive the packets with the correct marking? will it be reset by the firewall?
Thanks in advance for my long-winded thread
