Fault Recovery
RMON provides the following fault recovery functions:
Interface Down—When an RMON-enabled interface goes down, monitoring continues. However, all data
values are registered as 0xFFFFFFFF (32 bits) or ixFFFFFFFFFFFFFFFF (64 bits). When the interface
comes back up, RMON monitoring processes resumes.
Stack Unit Down—When a stack unit goes down, all sampled data is lost. But the RMON configurations
are saved in the configuration file, and the sampling process continues after the stack unit returns to
operation.
Platform Adaptation—RMON supports all Dell Networking chassis and all Dell Networking
Ethernet.interfaces.
Note: A Network Management System (NMS) should be ready to interpret a down interface
and plot the interface performance graph accordingly.
