3 To verify the IP address, type show ip interface at the system prompt, as
shown in the following example.
When configuring/receiving IP addresses through DHCP and BOOTP (an
older version of DHCP), the configuration received from these servers
includes the IP address and may include the subnet mask and default
gateway.
NOTE: It is not necessary to delete the device configuration to retrieve an IP
address from the DHCP server.
NOTE: When copying configuration files, avoid using a configuration file that
contains an instruction to enable DHCP on an interface that connects to the same
DHCP server, or to one with an identical configuration. In this instance, the device
retrieves the new configuration file and boots from it. The device then enables
DHCP, as instructed in the new configuration file, and the DHCP instructs it to reload
the same file.
NOTE: If you configure a DHCP IP address, this address is dynamically retrieved,
and the ip address dhcp command is saved in the configuration file. In the event of
master failure, the backup will again attempt to retrieve a DHCP address. This could
result in one of the following:
• The same IP address may be assigned.
• A different IP address may be assigned, which could result in loss of
connectivity to the management station.
• The DHCP server may be down, which would result in IP address retrieval
failure, and possible loss of connectivity to the management station.
Receiving an IP Address From a BOOTP Server
The standard BOOTP protocol is supported and enables the device to
automatically download its IP host configuration from any standard BOOTP
server in the network. In this case, the device acts as a BOOTP client.
