I'd like to mark some traffic so any other traffic has priority, except that my marked-down traffic has a guaranteed minimum rate. When there's no other traffic, my marked traffic can use the full TLS Ethernet bandwidth.
Possible? If so, can someone point me in the right direction? Router/L2/L3 switch are all available. Thanks!
What you're asking seems to be no problem at all.
Let me get this straight, you would like to mark some traffic (lets call it traffic type A) so that all Other traffic has a higher priority?
Do you already have a QoS policy set up for your network? ie, marking voice with ef, or DSCP 46 or IPP 5, video with 34 or AF41 or IPP4 etc?
I assume the TLS link is entirely yours? ie, no shared bandwidth through a carrier etc?
If you own the link completely, then you can set your own QoS policy however you want it.
To do what you're asking you will need to set ALL traffic to a higher priority than your selected traffic.
ip access-list extended ALL_TRAFFIC
permit ip any any
ip access-list extended SELECTED_TRAFFIC
permit ip X.X.X.X 0.0.0.XX Y.Y.Y.Y 0.0.0.YY
deny ip any any
class-map match-any ALL-TRAFFIC
match ip ALL_TRAFFIC
class-map match-any SELECTED-TRAFFIC
match ip SELECTED_TRAFFIC
bandwidth percent <75%-min bwidth>
set dscp cs2
set dscp cs1
Assign the policy map to your outgoing interface in an the outgoing direction and it should work.
I hope :)
Hope that answers your question!
