Enterasys X-Pedition 8000/8600 Getting Started Guide 3
Specifications
This guide and other X-Pedition documentation refers to the X-Pedition’s Layer-2 (L2), Layer-3
(L3), and Layer-4 (L4) switching and routing. These layers are based on the International Standards
Organization (ISO) 7-layer reference model. Here is an example of that model. The X-Pedition
operates within the layers that are not shaded. Notice that Layer 2 is divided into an LLC layer and
a MAC layer. The X-Pedition operates at the MAC layer but not the LLC layer.
Port mirroring • Traffic to the control module
• Traffic from specific ports
• Traffic to specific chassis slots (line cards)
Hot swapping • Line cards
• Control module (when redundant control module is installed and online)
• Switching Fabric Modules (X-Pedition 8600 only—when redundant switch
fabric is installed and online)
• Power Supply (when redundant supply is installed and online)
Load balancing/
sharing • Enterasys SmartTRUNK support
