We have a Cisco Switched network with thee VLANS (1, 20 ,30), The core switch has Layer 3 capabilities but nis function is not utilised as no communications betwwen VLANS is required.
The traffic on VALN 20 is delay sensitive and we need to look at giving it priority accross the VLAN trunks that interconnect the switches. I am having a hard time working our how to apply DSCP values and prioritise all traffic on VLAN 20.
I have been trawling documents on Ciso's website but most of these resources are for Layer 3 QOS, I simply need to give VLAN 20 traffic Priority at Layer 2 to ensure that is gets the fastest service from the switches on the network.
Any Ideas on how this can be achieived?
