Avaya P460 Supervisor Module Features
Introduction
The Avaya P460 Supervisor module provides the following functionality:
• Chassis-wide control
• I/O module initialization
• Fabric initialization
• Switching that also uses also the fabric of the second SPV
• Layer 3 functionality including routing
• SNMP Management agent
• PSU & Fans monitoring
• Power Budgeting & Management
• User interface
• Management interface
At least one SPV is essential for the switch operation. When two SPVs are installed,
one serves as the active, while the other one is a stand-by.
The switching fabric of a standby Supervisor module actively participates in packet
switching/routing even when its CPU is inactive.
M460ML-SPV Supervisor Module Modes:
• Active – The Supervisor Module is operating
• Standby – This Supervisor Module is fully synchronized with the Active one and
can replace it in the case of failure.
• Halted – This Supervisor Module is not synchronized with the Active one and
cannot act as a standby module.
You can verify the Supervisor Module mode by:
• The ACT and OPR LED status (refer to Table 3.1),
• The show SPV CLI using the command, or
• The P460 Manager
