Yealink T27G - Cisco 3650 QoS Question

[amir_]

We are migrating from Cisco phones to Yealink phones. This Yealink model supports CDP and I can see the phone via show cdp neighbor interface command on my Cisco switch.

We are running the usual auto qos commands:

interface GigabitEthernet1/0/24
description
switchport access vlan 110
switchport mode access
switchport voice vlan 114
trust device cisco-phone
auto qos voip cisco-phone
spanning-tree portfast
service-policy input AutoQos-4.0-CiscoPhone-Input-Policy
service-policy output AutoQos-4.0-Output-Policy

My question is - has anyone confirmed that Cisco switches with the "trust device cisco-phone" statement will recognize these Yealinks via CDP and trust the EF 46 markings from the phone?

Thanks,

Amir

Seems like this should probably be in either the Cisco or Yealink forums as it is not 3CX specfic. Much more likely to find someone who's been through that scenario. Or a quick plug-in phone and capture. That being said I can't remember the last time I had a LAN congestion issue that required QoS. VLAN usually does the trick.
