Hi All,
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
interface GigabitEthernet6/0/46 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 priority-queue out mls qos trust device cisco-phone mls qos trust cos auto qos voip cisco-phone spanning-tree portfast 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 priority-queue out |
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 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?
Subinterface ports
interface GigabitEthernet0/0.10 description ### VOICE VLAN INTERFACE ### encapsulation dot1Q 10 ip address 192.168.10.254 255.255.255.0 ! |
Interface 0/1 to Private network (class-maps and policy maps)
class-map match-all AllTraffic
ip access-list extended voip-signal
interface GigabitEthernet0/1 description ### Private Network ### ip address 192.168.255.2 255.255.255.252 duplex full speed 100 service-policy input mark-all service-policy output shape-wan ! |
Still looking into what all these values mean.

Hello
make
show policy-map int GigabitEthernet0/1
and
show policy-map interface GigabitEthernet6/0/46
and copy-paste here
05-09-2012 10:05 PM
show policy-map interface GigabitEthernet6/0/46 (This is off the Melbourne 3750G-USER01 switch)
GigabitEthernet6/0/46 Service-policy input: AUTOQOS-SRND4-CISCOPHONE-POLICY Class-map: AUTOQOS_VOIP_DATA_CLASS (match-all) Class-map: AUTOQOS_VOIP_SIGNAL_CLASS (match-all) Class-map: AUTOQOS_DEFAULT_CLASS (match-all) Class-map: class-default (match-any) |
show policy-map int GigabitEthernet0/1 (Off the Melbourne 2800 Router )
GigabitEthernet0/1 Service-policy input: mark-all Class-map: voip-rtp (match-any) Class-map: voip-sig (match-any) Class-map: class-default (match-any) Service-policy output: shape-wan Class-map: AllTraffic (match-all) Adapt Queue Packets Bytes Packets Bytes Shaping Service-policy : llq-voip Class-map: voip-rtp (match-any) Class-map: voip-sig (match-any) Class-map: JTAPI (match-any) Class-map: class-default (match-any) dscp Transmitted Random drop Tail drop Minimum Maximum Mark

Hope this helps?
Do I need any class-maps policy-maps set on the Melbourne 3750X-CORE and 3750X switches.
* I am looking at basic Qos rules Voip packets take priority ... leave all other data packets untouched.
Thanks for having a look. Cheers

probably qos works on GigabitEthernet0/1
but not shure on another

If I have AutoQos set on the 3750-User01 with all the qos maps and thresholds do these need to be applied to all the switches in our network for qos to run properly?
