Good Day all
This is a bit (actually a lot) of an engineering question. I have two 3548P's with a VLAN for VOIP and A VLAN for Management and nothing but Polycom phones plugged into it, , They are stacked (I guess) together By Ethernet connections between the two. I recently changed my network from where these switches had a single trunk to a pair of stacked 6224's to 2 Port channesl on each switch with a link to a pair of NEW S25N's using VRRP for Virtual redundancy. After this new config I am getting complaints of Static, Noise some choppiness and some drops. So the 3548's look like a basic setup for VOIP with
QOS BASIC
QOS TRUST COS
SO I am trying to figure out how to configure QoS on either the 3548's or the S25N's for optimal traffic flow for my VOIP TRAFFIC. There is NO QoS on the S25N's configured as of yet I am not sure if I need it if it is on the 3548's. I am certain I need to in order to tell the switch that the VOIP Traffic has priority. But Not sure how.
Can Anyone assist?
