Management mode
Decide how the PTP 800 will be managed.
In the default out-of-band local management mode, the management agent can be
reached only from the Management port of the CMU. This mode is appropriate
during installation when the equipment is managed using a locally connected PC at
each end of the link. It may additionally be useful where network management
communication is based on a completely independent data network (for example,
one based on a 3G cellular wireless terminal at each site).
In many network applications the wireless link will provide the only communication
path to a remote site. In such applications, CMUs and other network equipment at
the remote site will be managed over the wireless link. For applications of this type,
select either out-of-band or in-band management mode.
Use the out-of-band management mode where management traffic is segregated
using a physically separate network interface at the CMU. Use the in-band
management mode where management traffic is multiplexed with customer traffic
at a single physical interface.
Make sure that the same management mode is selected for CMUs at both ends of a
link. See
management modes.
NOTE
VLAN membership
Decide if the IP interface of the CMU management agent will be connected in a
VLAN. If so, decide if this is a standard (IEEE 802.1Q) VLAN or provider bridged
(IEEE 802.1ad) VLAN, and select the VLAN ID for this VLAN.
Use of a separate management VLAN is strongly recommended for applications
based on the in-band management mode. Use of the management VLAN helps to
ensure that the CMU management agent cannot be accessed by customers.

Management network
When using out-of-band management mode, avoid connecting
Management and Data ports in the same network. Loops in the network
can be complicated to detect and correct.
