The Cisco Catalyst 6500 Series with Cisco IOS Software Modularity, first released in Release
12.2(18)SXF4, boosts operational efficiency and minimizes downtime through evolutionary
software infrastructure advancements providing operational consistency, protected memory, fault
containment, process restartability, modularized processes, and Subsystem ISSU. These
enhancements are delivered in Cisco IOS Software for the Cisco Catalyst 6500 Series Supervisor
Engine 720, Cisco Catalyst 6500 Supervisor Engine 32, and Cisco Catalyst ME-6524 maintaining
the feature richness and operational environment already familiar to network operators.
By enabling modular Cisco IOS Software subsystems to run in independent processes, this
innovation:
●
Minimizes unplanned downtime through self-healing processes
●
Simplifies software changes through subsystem ISSU
●
Enables process-level, automated policy control by integrating Embedded Event Manager
(EEM)
