Ethernet port allocation
Port allocation rules
Decide how the three ODU Ethernet ports will be allocated to customer Data Service, Second
Data Service, Management Service and Local Management Service based on the following
rules:
• Map the
Data Service
to one of the three wired Ethernet ports.
• If required, map the optional
Second Data Service
to one of the remaining wired Ethernet
ports. If the Second Data Service is not required, select
None
. The Second Data Service is
available only in ODUs with a Full capacity license.
• If required, map the
Management Service
to one of the Ethernet ports, otherwise select
None
. The Management Service will be In-Band if it shares a port with the Data Service or
Second Data Service, otherwise it will be Out-of-Band. Out-of-Band Management is not
available when the Second Data Service is enabled.
• If required, enable the
Local Management Service
on one or more of the remaining unused
Ethernet ports.
The LAN Configuration page ensures that the Management Agent can always be reached using
either the
Management Service
or the
Local Management Service
.
Mapping of ports and services
The rules described above allow for the following twelve distinct combinations of services:
