19.1.1
Adaptive Bandwidth Notification Overview (CLI)
Adaptive Bandwidth Notification (ABN), also known as Ethernet Operation and
Maintenance (EOAM), enables third party applications to learn about bandwidth
changes in a radio link when ACM is active. Once ABN is enabled, the radio unit
reports bandwidth information to upstream third-party switches.
The ABN entity creates a logical relationship between a radio interface or a logical
group of radio interfaces, called the Monitored Interface, and an Ethernet
interface or a logical group of Ethernet interfaces, called the Control Interface.
When bandwidth degrades from the nominal value in the monitored interface,
messages relaying the actual bandwidth values are periodically sent over the
Control Interface. A termination message is sent once the bandwidth returns to its
nominal level.
19.1.2
Configuring an ABN Entity (CLI)
You must first create an ABN entity consisting of the Monitored Interface on the
one hand, and the Control Interface on the other. You must then use separate
commands to enable or disable bandwidth monitoring of the monitored interface
and transmission of messages. You can also set various parameters relating to the
bandwidth sampling and the transmitted bandwidth messages.
To create an ABN entity consisting of a physical radio interface as the monitored
interface and a physical Ethernet interface as the control interface, enter the
following command in root view:
root> ethernet abn abn-entity-create abn-name <ab-name>
monitored-interface <monitored-interface> monitored-slot
<monitored-slot> monitored-port <monitored-port> control-
interface <control-interface> control-slot <control-slot>
control-port <control-port> vlan <vlan>
To create an ABN entity consisting of a physical radio interface as the monitored
interface and an interface group as the control interface, enter the following
command in root view:
