Configuring Interfaces and Switches

---

Goals

• Deploy networking devices
• Explain network interfaces
• Deploy common Ethernet switching features
• Troubleshoot transceiver and switching issues

Network Interfaces

A network interface is the means by which a node is connected to the media and exchanges data with other network hosts.

• involves:

  • a physical connection to the network media
  • data link protocol for addressing and framing

• Network Interface Card (NIC)

• Modular Transceivers

• Transceiver Mismatch Issues

• Transceiver Signal Strength Issues

• Ethernet Frame Format

• MAC Address Format

Ethernet Switches

• Hubs
• Bridge
• Switches
• Ethernet Switch Types
• Switch Interface Configuration

Switch Port Configuration

• Link Aggregation and NIC Teaming
• Maximum Transmission Unit (MTU)
• Spanning Tree Protocol (STP)
• Spanning Tree Protocol Configuration
• Power Over Ethernet (PoE)
  • Power over Ethernet
  • reconcile these into a single page

Switch Troubleshooting

• Switch Hardware Failure Issues
• Switch Port Status Indicators
• Switch Show Commands
• Switch Interface Error Counts
• MAC Address Table
• Network Loop and Broadcast Storm Issues
