Hi All
We have an issue with some phones that cannot get IP addresses on our 9200L switches.
We have done some digging and my colleague has found a potential fix, if we turn off the command "auto qos voip cisco-phone" on the interfaces, it starts to work.
The config on the port is below
interface GigabitEthernet1/0/11
description Standard User port
switchport access vlan 1951
switchport mode access
switchport voice vlan 2001
no logging event link-status
trust device cisco-phone
snmp trap mac-notification change added
snmp trap mac-notification change removed
storm-control broadcast level 1.00
storm-control multicast level 1.00
storm-control action trap
auto qos voip cisco-phone
spanning-tree portfast
spanning-tree bpduguard enable
service-policy input AutoQos-4.0-CiscoPhone-Input-Policy
service-policy output AutoQos-4.0-Output-Policy
This only seems to happen on any brand new 9200s with the 17.x.x version of software, we have older 9200L with Version 16.09.03 and it works fine on them.
Any ideas?
