Chapter 3 Assigning the Switch IP Address and Default Gateway

Assigning Switch Information

You can assign IP information through the switch setup program, through a DHCP server, or manually.
Use the switch setup program if you want to be prompted for specific IP information. With this program,
you can also configure a hostname and an enable secret password. It gives you the option of assigning a
Telnet password (to provide security during remote management) and configuring your switch as a
command or member switch of a cluster or as a standalone switch. For more information about the setup
program, see the hardware installation guide.
The switch stack is managed through a single IP address. The IP address is a system-level setting and is
not specific to the stack master or to any other stack member. You can still manage the stack through the
same IP address even if you remove the stack master or any other stack member from the stack, provided
there is IP connectivity.
Stack members retain their IP address when you remove them from a switch stack. To avoid a conflict
Note
by having two devices with the same IP address in your network, change the IP address of the switch
that you removed from the switch stack
Use a DHCP server for centralized control and automatic assignment of IP information after the server
is configured.
Note If you are using DHCP, do not respond to any of the questions in the setup program until the switch
receives the dynamically assigned IP address and reads the configuration file.
If you are an experienced user familiar with the switch configuration steps, manually configure the
switch. Otherwise, use the setup program described previously.
