This chapter describes basic interface configurations for your Layer 3 switch router. Also included are sections about configuring virtual LANs (VLANs), packet-over-SONET interfaces, ATM uplink interfaces, and port snooping.

Unless otherwise noted, the information in this chapter applies to the Catalyst 8540 CSR,

Catalyst 8510 CSR, and Catalyst 8540 MSR with Layer 3 functionality. For further information about the commands used in this chapter, refer to the command reference publications in the Cisco IOS documentation set and to Appendix A, “Command Reference.”

This chapter includes the following sections:

•Overview of Interface Configuration

•General Instructions for Configuring Interfaces

•About Layer 3 Switching Interfaces

•About Virtual LANs

•Configuring ISL VLAN Encapsulation

•Configuring 802.1Q VLAN Encapsulation

Note You are at Step 3 in the suggested process for configuring your switch router (see the “Suggested Procedure for Configuring Your Switch Router” section on page 2-1). You should have already configured the processor module (and LAN emulation on the Catalyst 8540 MSR) and now be ready to proceed with configuring interfaces.
