Priority for management traffic
Choose the Ethernet priority for management traffic generated within the CMU
management agent. The priority should be selected so as to be consistent with
existing policy on priority of management traffic in the network. Use of a high
priority is strongly recommended for applications based on the in-band
management mode to ensure that management traffic is not discarded if the link is
overloaded.
IP interface
Choose an IP address for the IP interface of the CMU management agent. The IP
address must be unique and valid for the connected network segment and VLAN.
Find out the correct subnet mask and gateway IP address for this network segment
and VLAN.
Ensure that the design of the data network permits bi-direction routing of IP
datagrams between network management systems and the CMUs. For example,
ensure that the gateway IP address identifies a router or other gateway that
provides access to the rest of the data network.

Quality of service for bridged Ethernet traffic
Choose an appropriate assignment between the priority code point in bridged
Ethernet frames and PTP 800 traffic classes. This assignment should be consistent
with quality of service policy in the rest of the customer data network.
The user interface provides a convenient shortcut to select the assignment
recommended in IEEE 802.1Q-2005.

bridged Ethernet traffic.
NOTE
When the wireless link is configured for out-of-band management, select an
appropriate setting for the Management CIR attribute. A high CIR will provide
greater capacity for management traffic, at the cost of allowing bursty management
traffic to have a greater impact on capacity remaining for customer traffic. A low
CIR may result in extended response times for network management traffic.

Ethernet priority information is coded in the Ethernet VLAN tag and
differentiated quality of service is therefore not available in a network
based on untagged Ethernet frames.
