Hi
I have an L2L between 2 switches (Cat 6500 with SUP-720 and Cat 6800 with Sup-2T-10G) through an L3 interface, we have already found too many total ouput drop on both sides, checking the interfaces that have the TX / RX They are not saturated.
One of the actions taken is to enable QoS on both ends, the packages are marked from the application with their respective DSCP (EF, AFXX)
Cat6500(config)#mls qos ! interface GigabitEthernetX/Y/Z no switchport ip address 172.X.X.X 255.255.255.252 mls qos trust dscp
Cat6800(Config)#mls qos
interface GigabitEthernetX/Y/Z
no switchport ip address 172.X.X.X 255.255.255.252
How I configure QoS DSCP on the interface?
I have the doubt if the configuration is correct, specially in the Cat6800 because I didn't find documentation about how to apply QoS on SUP-2T-10G.
Does anyone know If I missed something?
Thanks and regards.
Hello Heriberto,
I have found links for QoS configuration guides for Sup 2T on catalyst 6500
see
This may be what are looking for DSCP based queueing.
I also provide the link to all the configuration guides so that you can look at all the docs abour QoS
And finally this is the launch page for C6800 config guide
The pages look like to be shared by the two platforms
Hope to help
