Avaya M770 Management Architecture
The back of the Avaya M770 hub has two slots which house the main and backup
Avaya M770 Supervisor modules, called M-SPV/M-SPX. The Supervisor module,
together with the CajunView network management system, provides a zoom view
of the Avaya M770 hub and all resident modules, regardless of technology. A
graphical display shows the position of each module in the hub and its status in
real-time. The Supervisor module also handles basic configuration functions such as
enabling and disabling settings. To perform more advanced configuration and
monitoring functions, the Avaya M770 Supervisor launches distributed
management sub-agents, located on the modules themselves. The distributed
management architecture allows no single point of failure for hub management; it is
implemented as follows:
• DomainX Avaya M770 modules are managed by an on-board CPU, which is
responsible for module management. The frame switch modules are managed
as SNMP sub-agents, with the main M-SPV serving as their SNMP agent.
• Avaya M770 ATM modules are managed as sub-agents by a single ATM
module which is designated as the SNMP agent for all other ATM modules in
the hub. Each Avaya M770 ATM module has an on-board agent CPU.
• Modules based on any future technology will also be managed independently,
by a member of that technology family (as with the ATM modules).
• All Avaya M440 modules are managed by NMA-RS or NMA-RE agents.
Note: For proper management of Avaya M440 modules in the Avaya M770 hub, the
NMA-RS/NMA-RE modules should be upgraded to S/W version 8.1.6.
