Chapter 3 Configuring the Switch IP Address and Default Gateway
Using BOOTP, DHCP, or RARP to Obtain an IP Address
This example shows how to configure SLIP on the console port and verify the configuration:

Using BOOTP, DHCP, or RARP to Obtain an IP Address
Note
For complete information on how the switch uses BOOTP, DHCP, or RARP to obtain its IP
configuration, see the
“Understanding How Automatic IP Configuration Works” section on page 3-2
.
To use BOOTP, DHCP, or RARP to obtain an IP address for the switch, perform this task:
Task
Command
Step 1
Make sure that there is a DHCP, BOOTP, or
RARP server on the network.
–
Step 2
Obtain the last address in the MAC address range
for module 1 (the supervisor engine). This address
is displayed under the MAC-Address(es) heading.
(With DHCP, this step is necessary only if using
the manual allocation method.)
show module
Step 3
Add an entry for each switch in the DHCP,
BOOTP, or RARP server configuration, mapping
the MAC address of the switch to the IP
configuration information for the switch. (With
DHCP, this step is necessary only if using the
manual or automatic allocation methods.)
–
Step 4
Set the sc0 interface IP address to 0.0.0.0.
set interface sc0 0.0.0.0
