Hello,
I am hoping that someone can help me. I am pretty good with Cisco but not so great with QOS, let me explain my situation.
Our current location has 2 different l2 switches that are not doing any routing at all. Those are the 2948 and 2960. I have phones connected to the 2960, on the ports i have put
switchport access vlan 55 switchport mode access switchport voice vlan 20 srr-queue bandwidth share 1 30 35 5 priority-queue out mls qos trust dscp auto qos trust spanning-tree portfast spanning-tree bpduguard enable service-policy input Voice_POLICY
and on the trunk port for the 2960 i have:
description UPLINK to CORE switchport mode trunk srr-queue bandwidth share 1 30 35 5 priority-queue out mls qos trust cos auto qos trust spanning-tree portfast disable
I just started working here and we have roughly 20 - 30 phone agents on the phones all the time and we are getting static and voice loss when talking. I looked and there does not appear to be any QOS enabled anywhere except what i have done above. I am wanting to enable QOS on the 2948 (That is how the 2960 connects back to our main router and also enable QOS on the 2821. I am at a loss when it comes to setting up QOS on the 2948 and for the 28281 i have:
class-map match-any VOIP match ip dscp ef match protocol rtp match ip precedence 6 match ip precedence 5 class-map match-any VOICE match access-group 130 class-map match-any MATCH-EF match ip dscp ef ! ! policy-map VOICE-MATCH class MATCH-EF class VOICE set ip precedence 5 policy-map VOIP-QOS class VOIP priority 960 class class-default fair-queue random-detect ! ! access-list 130 permit ip any 10.10x.x.xxx 0.0.0.255 interface GigabitEthernet0/0 service-policy output VOIP-QOS interface GigabitEthernet0/1.4 service-policy output VOICE-MATCH
My questions are:
1) Is there anything else i need to do on the 2960?
2) For the 2948 how do i enable QOS so my voice packets still take priority?
3) The 2821 config i believe is correct but want to make sure i am heading the correct direction.
*Also we have 2 differnet types of phones, altigen 720's and Polycoms.
Please help

I thought that the 2821 could handle gig speeds?
