AutoQOS for Shoretel Phone System

[njfanelli]

Good Afternoon,
We are currently in the process of implementing a new Shoretel VoIP Phone system in our
network.  We have a Cisco Catalyst 6506e at the core for routing and Cisco Catalyst 2960S
switches at the edge for all client connections. We'd like to enable AutoQOS on our
switches for VOIP traffic but I’m uncertain on whether this is strictly a feature Cisco
phones (not Shoretel) and whether our 6506e switch will support it.

Here is an overview of our network
SHORETEL SERVER VLAN (Cisco 2960s)
172.16.0.0/24

DATA NETWORK
192.168.0.0/16

BO VLAN (Cisco 2960s)
VOICE -172.16.10.0/24
DATA - 192.168.10.0/24

The Shoretel phones we're using are IP230g, the clients workstation will connect directly
to the phone and then the phone connects to the 2960s switch.  The phone will acquire a
DHCP address from our DHCP on the Data Network

From what I gather here is what i would need to change at the Edge:

Existing port configuration...
interface GigabitEthernet1/0/3
switchport access vlan 10
switchport mode access
switchport port-security
switchport port-security aging time 5
switchport port-security violation restrict
switchport port-security aging type inactivity

New Port Configuration...
interface GigabitEthernet1/0/3
switchport mode trunk
switchport trunk encapsulation dot1q
switchport trunk native 10
mls qos trust dscp
auto qos voip trust
switchport nonegotiate
switchport port-security
switchport port-security aging time 5
switchport port-security violation restrict
switchport port-security aging type inactivity

Unfortunately, i'm not sure what need to change at the core level to support AutoQOS.

Thanks in advance!

Hi,

AutoQos is used for Cisco phones

cisco-phone—When you enter the auto qos voip cisco-phone interface configuration command on a port at the edge of a network that is connected to a Cisco IP Phone, the switch enables the conditional-trusted boundary feature. The switch uses the Cisco Discovery Protocol (CDP) to detect the presence or absence of a Cisco IP Phone. When a Cisco IP Phone is detected, the ingress classification on the interface is set to trust the CoS marking of the received packet. When a Cisco IP Phone is absent, the ingress classification is set to not trust the CoS (or DSCP) value of any packet.

the options are:

auto qos voip cisco-phone

auto qos voip cisco-softphone

Thanks for your reply, however, my environment contains Cisco switches at the edge & core but we are using ShoreTel IP230g phones at the desk.  From what I understand "auto qos voip cisco-phone" will not work in my scenario because I'm using ShoreTel hardware and this command is proprietary to Cisco phones, the command that I need to use is "mls qos trust dscp" with the command "auto qos voip trust" per port on the edge but do i need to set the DSCP markings?  Also, I'm not sure what needs to be changed at the core.

Thanks,

Yes you can use AutoQOS with Shoretel. You need to also use LLDP, but not CDP.

lldp run

switchport access vlan xx

switchport voice vlan xx

switchport mode access

spanning-tree portfas

srr-queue bandwidth share 10 10 60 20

priority-queue out

mls qos trust dscp

auto qos voip trust

no cdp enable
