Stupid question but bugging me.
In this link, it says a 2801 can do 46mbit CEF but the router has 100mbit interfaces.

Does this mean a 2801 can never reach speeds faster than 46mbit even though...
ok, that makes sense. The device's value of COS = 6 is referring to IP Precedence of 6 (Internet). It just strikes me as odd that this voip device has Diffserv = 46 but COS = 6 when I thought it should be 5.
Thanks!
Hello, From my understanding of QoS for voice traffic, the TOS/Diffserv should be 46 and precedence 5.
My question is, I have a device that list the correct TOS/Diffserv, but then has COS value 6. Is COS the same as IP Precedence? If so, shouldn't the COS value be 5?
Here's the weird...
Thanks for the information. My serial interface queueing strategy is FIFO. Will WRED still work or does the interface need to be CB-WFQ? Lastly, if I apply WRED to the policy-map, I need to make sure the voip traffic coming from my LAN has the proper DSCP markings, right?
The voip phones on the LAN (5 total) are from a hosted provider and the codec they're using is G.729. Not sure of the sample size and all phones should be able to make calls simultaneously The router isn't running any sort of CAC, just the service-policies.
The router is a 1750 and the Ethernet side connects to a firewall then to the LAN. It just seems odd that more bandwidth isn't reserved. The Serial side is 384k and it has a similar service-policy.

I'm reviewing a service-policy setup by a consultant that has only 192kb prioritized on an ethernet interface. I don't understand why you would do this on a ethernet int when I have 100mb and no congestion.
