Configuring Multiple Interfaces Simultaneously Securing Telnet Access to the Switch
IOS Concessions to Set-Based Commands The 3550 Metaphor for Interfaces L2 Functionality with Pure Switches
802.1x -- Port Based Authentication
Spanning Tree Protocol (STP): IEEE 802.1D RSTP Uplink Fast/Backbone Fast Configuration PortFast
VLAN Configuration Standard-Range VLAN Configuration Configuring Extended VLANs Verifying VLAN Configuration VLAN Trunk Protocol (VTP) Configuration PVST MSTP
Fast EtherChannel L3 Functionality Possible with Two or More Routers with VLAN Capability
Layer 3 -- Routing
Hot-Standby Router Protocol (HSRP) Service Provider-Oriented Functions
NBMA VLANs
802.1Q (VLAN) Tunneling Clustering Switch Optimization

VLAN-Maps
When to Use Access-Lists and VLAN-Maps Between the Layers -- Fallback Bridging
Case 1: Routed Interfaces
Case 2: Interfaces in Different VLANs Quality of Service (QoS)
Enabling QoS on the 3550
Using Class-Maps Example 1: Classify, Police, and Mark Using Policy Maps. Example 2: Classify, Police, and Mark Traffic Using Aggregate Policers
