I have an issue with the QoS on my router 1803, it runs with the IOS version 12.4(15). There are 9 fast Ethernet, 8 of wich are switch ports. On the other side I have a 2950 switch with my hosts on it. The Internet access goes through the Fa0 of my router.
On my network there's a device that is delay sensitive and needs to take precedence over the other traffic on my network (represent by a computer on my diagram). Since I can't set the DSCP field to the value I want to mark my traffic with my switch I use the cos et set it to 5 with the command "mls qos cos 5". Since the cos is only see when 802.1Q is in place I couldn't set the port connecting to my router in access mode, so set up a trunk between the two devices. I have a class map that recognizes the the dscp field I want and a policy map that prioritize it, all the other traffic uses WFQ.
WIth my topology it doesn't work obviously since the DSCP field doesn't get marked at any point. I'm not sure what I should do to mark my DSCP field, I don't want to implement a policy map that marks my inbound traffic based on access list or anything else for that matter, but I can't come up with another solution. Ideally I'd like to find a way to mark my dscp field on the switch, but it doesn't support class maps. Has anyone any idea?
Here we will go over the configuration needed for MACsec Switch to Switch using a Pre-Shared Key. Topics that will be covered include, command usage, key derivation and key server election. Please see the MACsec History and Terminology for ...
