This question has probably been asked a million times but I cannot find a solid answer. We had our routers setup by an external company and I'm not sure if they completely finished the Qos settings on the routers. How do I check?
I am new to QoS so bear with me.
Our setup can be seen in the diagram attached.
The user switches are running AutoQos on each port
description ### CISCO VOICE & DATA PORT ###
switchport access vlan 5
switchport mode access
switchport voice vlan 10
srr-queue bandwidth share 10 10 60 20
queue-set 2 <-- Not sure why this is set on some switches and not on others
mls qos trust device cisco-phone
mls qos trust cos
auto qos voip cisco-phone
service-policy input AutoQoS-Police-CiscoPhone
There is a global QoS config set automatically by AutoQos template.
The Etherchannel-Trunk ports from the user switches to the Core switches and vice versa have the following commands set
mls qos trust dscp
Q1: What Qos settings need to be added to the core switch? I have no phones are attached to it.
Currently we have the following global Qos values set
mls qos map cos-dscp 0 8 16 24 32 46 48 56
Q2: What Qos settings need to be added to the router subinterface ports and global configs.
mls qos is not set globally but there are a bunch of policy-maps and class-maps?

I'm not able to access my old voice mail messages all of a sudden. The recording says something like 'the message is currently not available'. This has never happened before in all the years I have been using this system. I have t...
If you have 2 ISR routers, one acting as Failover, do we need to have both the same number of SRST licenses on the 2 routers?
No. You will only need the SRST licenses on the primary router. Because this feature...
