We detected on a customer that Cisco IP Phones are requesting DHCP in the data VLAN (as well as requesting DHCP in the voice VLAN).
We see the logs on the DHCP server of those requests on the data VLAN (which get replied and an IP address and lease is assigned to the IP Phone).
However, we are not able to ping the IP Phone on the data VLAN and the IP Phone is correctly registering on the CallManager with the IP address of the voice VLAN (which it is also getting from the DHCP server).
We are using CallManager 6.1.
The configuration of the switches ports is as follows:
switchport access vlan 10
switchport mode access
switchport voice vlan 20
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
mls qos trust device cisco-phone
mls qos trust cos
no snmp trap link-status
auto qos voip cisco-phone
Has anyone faced this issue?
