CH A P T E R 3 Configuring the Switch IP Address and Default Gateway This chapter describes how to configure the IP address, subnet mask, and default gateway on the Catalyst enterprise LAN switches. Note For complete syntax and usage information for the commands used in this chapter, refer to the Command Reference-Catalyst 4000 Family, Catalyst 2948G, and Catalyst 2980G Switches. This chapter consists of these sections: • Understanding the Switch Management Interfaces, page 3-1 • Understanding Automatic IP Configuration, page 3-2 • Preparing to Configure the IP Address and Default Gateway, page 3-4 • Default IP Address and Default Gateway Configuration, page 3-5 • Setting the In-Band (sc0) Interface IP Address, page 3-5 • Setting the Management Ethernet (me1) Interface IP Address, page 3-6 • Configuring Default Gateways, page 3-7 • Configuring the SLIP (sl0) Interface on the Console Port, page 3-8 • Using DHCP or RARP to Obtain an IP Address Configuration, page 3-10 • Renewing and Releasing a DHCP-Assigned IP Address, page 3-11 Understanding the Switch Management Interfaces The Catalyst 4000 family, the Catalyst 2948G, and the Catalyst 2980G switches have three management interfaces: • In-band interface (sc0) • SLIP interface (s10) • Management Ethernet interface (me1) The in-band (sc0) management interface is connected to the switching fabric and participates in all of the functions of a normal switch port, such as spanning tree, Cisco Discovery Protocol (CDP), and VLAN membership. The out-of-band management interfaces (me1 and sl0) are not connected to the switching fabric and do not participate in any of these functions. 78-12647-02 Software Configuration Guide-Catalyst 4000 Family, Catalyst 2948G, Catalyst 2980G, Releases 6.3 and 6.4 3-1
