I'm trying to understand IP Phones better. I'm have trouble understanding the CoS/ToS that a softphone application configures and uses. This is important to me since I want to know the QoS and How it is determined between nodes on the same switch in the same vlan. I keep getting the same response back, but first a scenario:
Cat. 6509 w/PFC2/MSFC2
Call Manager on separate Segment
Each switch has Vlans for separate Voice and Data where applicable, but this is not feasible when softphones are used as standalone devices
A supervisor receives a phone call from his employee in the same location. While the supervisor is helping his employee, another call form an internal employee comes in. At the same time or maybe before the calls started the supervisor is downloading a large file which will take an extensive amount of time. How is QoS insured in this case?
I know the IPPREC and DSCP are Lyr3 ToS and CoS is Lyr 2.
I know the IPPrec and DSCP are not supported on the 6348 blade since the blade is Lyr2.
I know the CoS is only supported for HardPhone QoS.
know the same answer I receive is not to the question I asking, It's the text book configuration for PC-Base softphone on the switch. Which will be configured for Segment to Segment and Vlan to Vlan communication.
What controls interVlan QoS for PC_Base Softphones and How if at all is it configured.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
