Management network
IP interface
The PTP 250 ODU contains an embedded management agent with a single IP interface.
Network management communication is exclusively based on IP and associated higher
layer transport and application protocols. The factory default IP address of the
management agent is 169.254.1.1. The products do not require use of supplementary
serial interfaces.
MAC address
The MAC address is not configurable by the user.
VLAN membership
The management agent can be configured to transmit and receive either untagged or
C-tagged (IEEE 802.1Q) frames. The VLAN ID can be 0 (priority tagged) or in the range 1
to 4094.
In-band management
In-band management is the only management mode offered (there is no out of band
management).
In the in-band management mode, the management agent can be reached from the
Ethernet port at the local ODU, and (assuming that the wireless link is established) the
Ethernet port at the remote ODU.
Wireless link down alert
PTP 250 offers a configurable email alert which can be set to send the user an email
message in the event of the wireless link going down.
Back-to-back links
PTP 250 will not operate correctly if a direct cabled connection is made between two PoE
power supply units. Where two or more links are deployed in a chain, always use an
Ethernet switch or router to interconnect the links at the relay points.
