Configuring the Switch IP Address and Default Gateway

Using BOOTP, DHCP, or RARP to Obtain an IP Address

For complete information on how the switch uses BOOTP, DHCP, or RARP to obtain its IP
Note
configuration, see the
To use BOOTP, DHCP, or RARP to obtain an IP address for the switch, perform this task:
Task
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.)
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.
Step 5
Reset the switch. The switch broadcasts DHCP
and RARP requests only when the switch boots
up.
Step 6
When the switch reboots, confirm that the sc0
interface IP address, subnet mask, and broadcast
address are set correctly.
Step 7
For DHCP, confirm that other options (such as the
default gateway address) are set correctly.
This example shows the switch broadcasting a DHCP request, receiving a DHCP offer, and configuring
the IP address and other IP parameters according to the contents of the DHCP offer:
