Ethernet bridging
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
VLAN tagging is not supported for the management agent.
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.
