Introduction

1.5.3 SmartSTACK 10 ELS10-26 Port Monitoring

Port monitoring allows the SmartSTACK 10 ELS10-26 to redirect network traffic (including MAC layer errors) from one port to the port monitoring port (MONX port), in effect “mirroring” all network traffic to this port. This feature allows users who have existing investments in external analyzers, external RMON probes, or devices like Network General's Distributed Sniffer SystemTM to continue to receive expert analysis and packet decode functions in a switched environment -- simply use the port mirroring function to mirror switched traffic to the designated “diagnostic” port to which the analyzer is attached.

The SmartSTACK 10 ELS10-26 supports local port mirroring. Local port mirroring is when the diagnostic port is on the same SmartSTACK 10 ELS10-26 as the mirrored port. The mirrored port has to be local to the SmartSTACK 10 ELS10-26.

Packet Capturing and Monitoring

Only the 10BASE-T ports on the SmartSTACK 10 ELS10-26 (and not the 100BASE ports) can be mirrored. The monitoring of network traffic is performed by the SmartSTACK 10 ELS10-26 hardware.

1.5.4 SmartSTACK 10 ELS10-26 Sample Applications

Just as a six lane highway allows you to travel much faster than a single lane highway, a network backbone creates high-speed connections for your network. In general, a network backbone allows you to distribute access to important network resources such as file or print servers. Additional SmartSTACK 10 ELS10-26 features, such as trunking, Fast Ethernet, and virtual workgroups allow you to optimize bandwidth and design a more efficient flow for your network traffic.
