•
To use dual port phone functionality when using VMPS then CDPv2 with the auxiliary VLAN
set must be used.
•
Location Change information can be collected by the IP phones using CDP. If this function-
ality is required using CDP then CDP must be enabled on the IP phone ports.
STP
•
Redundant connections from the 3300 ICP to the network Layer2 switches are allowed
when Spanning Tree functionality is enabled on the controller.
•
Location Change information can be collected by the IP phones using Spanning Tree BP-
DUs. If this functionality is not required, then STP does not need to be enabled on the IP
phone ports.
NETWORK QOS SETTINGS IN A CISCO ENVIRONMENT
A number of higher-end Cisco switches have the capability to monitor both Layer 2 and Layer
3 QoS settings at ingress. They can also modify either of these settings based on the other
setting, as well as changing values, if necessary. Good understanding of these settings is
needed if correct operation is to result throughout the network. To simplify the installation and
use some pre-packaged commands, such as
auto-qos
, a COS value of 5 is recommended
throughout the network. Other values, such as 6, can still be used, but will require additional
tuning of the configuration at different ports.
In order to make the QoS settings work, the following points need to be considered:
•
QoS must be enabled for the entire switch.
•
The default COS and DSCP settings of the switch may not be those needed for voice.
•
Settings that are needed include:
-
Change mapping COS 5 to DSCP of 46 (Expedited Forwarding (EF) setting).
-
Ensure that COS 5 is mapped to the EF queue.
-
Enable the EF queue.
-
Trust incoming ports based on COS value for endpoints, phones, 3300 ICP and voice
servers.
-
PC phones may require DSCP remapping as well as DSCP to COS conversion.
-
Enable CDP.
•
Auto-qos trust
will change a number of these settings.
•
Some additional tuning may be needed to the settings to get full operation.
MiVoice Business can apply different LAN QoS policies to voice packets, signalling packets
and other packets. The LAN Policy (QoS) form in ESM is used for setting the LAN QoS policy
values.
