Diagnosing Switch Problems; In This Chapter - Alcatel OmniSwitch 6624 Network Configuration Manual

Several tools are available for diagnosing problems that may occur with the switch. These tools include
Port Mirroring
•
Remote Monitoring (RMON) probes
•
Switch Health Monitoring
•
Port mirroring copies all incoming and outgoing traffic from a single mirrored Ethernet port to a second
mirroring Ethernet port, where it can be monitored with a Remote Network Monitoring (RMON) probe or
network analysis device without disrupting traffic flow on the mirrored port. Switch Health monitoring
software checks previously-configured threshold levels for the switch's consumable resources, and noti-
fies the Network Monitoring Station (NMS) if those limits are violated.

In This Chapter

This chapter describes the port mirroring, remote monitoring (RMON) probes, and switch health features
and how to configure them through the Command Line Interface (CLI).
Configuration procedures described in this chapter include:
