Good afternoon, we have a 1Gb/s internet circuit, which, for reasons we fully understand often gets fully utilised due to business need.
All switches are 9300s' running 17.6.3
We dont currently have a QoS policy on the wired network (Wireless is another matter)
During times of peak congestion, we have MS Teams Audio/Video issues, and thus was to implement a basic policy to
A) Mark traffic at the access port, only for MS Teams
B) Prioritise traffic on DSCP value at the WAN edge.
C) All other traffic will be marked down to DSCP default inbound/outbound
We dont intend to do any priority queueing upstream from access to core as links are in 20Gb/s etherchannel and utilisation never goes above 10%, plus DSCP is honoured by default on the 9300 platform.
Core switch is connected via LAG to our edge firewalls, which terminate the 1Gb/s WAN circuit.
Would anyone be able to state whether this looks reasonable please?
