In This Chapter - Alcatel-Lucent OmniSwitch 6850-48 Network Configuration Manual

Several tools are available for diagnosing problems that may occur with the switch. These tools include:
•
Port Mirroring
•
Port Monitoring
•
sFlow
•
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. The port monitoring feature
allows you to examine packets to and from a specific Ethernet port. sFlow is used for measuring high
speed switched network traffic. It is also used for collecting, storing, and analyzing the traffic data. Switch
Health monitoring software checks previously configured threshold levels for the switch's consumable
resources, and notifies the Network Monitoring Station (NMS) if those limits are violated.

In This Chapter

This chapter describes port mirroring, port monitoring, remote monitoring (RMON) probes, sFlow, and
switch health features and explains how to configure the same through the Command Line Interface (CLI).
