– MA Concept and Functions
The MA™ (Micro Agent) is an on-chip management system providing the monitoring
and management of remote access devices without the need of an expensive
SNMP agent module. The MA™ does not require an IP address
The chip is embedded in both the remote units, mostly referred to as a CPE, and in
the access concentrator device deployed in the access node. A unique secured in-
band management protocol allows the two devices communicating between
themselves over the fiber link bi-directionally, therefore both monitoring and
management commands can be remotely performed on the CPE. Control frames
are not forwarded to data ports
Micro Agent Basic System Block Diagram
When
MA™
enabled devices are deployed at both ends of the fiber link, they
automatically learn about each other’s presence and begin providing full remote
management functions within 20 to 30m.seconds from the moment the link has
been established. However, if an
MA™
enabled devices cannot complete such
handshake within that time, it concludes that the opposite end device is not
MA™
enabled, subsequently it bypasses its special functions and operates like a
standard, straight forward access device. Therefore there are no interoperability
issues between network devices which have
MA™
chips embedded in them and
those that have not.
The following management functions are available for the MCM1000S/L
module through an MA™ enabled and SNMP managed MetroStar:
Module status: display the MCM1000S/L ports basic status and configuration
settings Link status (SX and LX), Signal Detect status (SX and LX)
, Channel’s enable
(LX), LST modes, Loop-back (SX and LX), SLE modes, Remote MA device type and
Power status)
Module Control
: provides the user with options to set the channel’s description,
LB/LST control, enable/disable channel,
and to restore the module’s defaults setting.
Link management: related to the complete MA link including both ends,
the module channel on the local side and the remote CPE MA device:
Link Status, Set link bandwidth, Enable/Disable Up/Downstream SLE, invoke MA
remote device menu, Restore link default parameters.
Note: for a detailed description, please refer to the MMM-01 Management
Manual (version 1.6.2 and up).
