VOIP QoS Setup
VOIP QoS Setup
this is a long winded thread but please keep with me
we are currently replacing all our random switches with FS728TP so we have a standard model on site (around 30 switches, 200 users, large open site conencted via fibre optic)
we are looking at a VOIP system at the beginning of next year
i need to make sure i make the most out of the switches regarding traffic management
i did not want to set a VLAN up as alot of the phone can connect via the computers which would need to be on the existing subnet
so i am looking at the QoS - on these switches i can only see CoS or DSCP can someone give me a run down of how i can use this with VOIP to manage traffic....i am reading and reading but not enough is sinking in - diagrams would of been easier but can see any that help
i have two options Cos or DSCP:
my view of CoS so far is that you can set levels on interfaces on how to want to prioritise that port from lowest to highest but this does not help me if the phone and computer are sharing the same interface
i am making sure all the switches are connected to each other via the trunk ports incase we ever wanted to use the VLAN capibility but i am trying to keep away - as our network has been surveyed and we are using 5% maximum bandwidth at any one time
DSCP i do not quite understand yet - this i something like queueing of traffic and and given priority to certain packet headers? which i guess could be helpful but i am unsure if i am looking at this is the correct way?
also we have three areas on site which i was thinking of placing 3x GSM7312 in out areas with multiple in/out fibre optics around our site and i am hoping i can set all the ports as trunk ports they are really just trunk port switches to feed out to the other FS728TP's
GSM7312: from what i have read on these i can set VOIP via the diffserv wizard to do my initial setup.......
then i was wondering if i set the QoS to DSCP Enabled on the FS728TP's would these learn and use the DSCP settings set on the GSM7312???? if so my solution is found but i need a confirmation that my mind is in the correct place
also....one last question - all the priorities are done on lowest to highest - if it was set to low..is there a bandwidth limit compared to highest?
sorry for the long story - i can create diagrams or make phone calls if anyone would like to leave something in my inbox directly - if not i will contact netgear technical support to see if they could help me but i dont want to get someone that will just agree with every word i say with it should do
