Because switch 4 (figure 8-7) received
its most recent IP addressing from a
DHCP/Bootp server, the switch
ignores the
ip preserve command and
implements the IP addressing
included in this file.
Figure 8-9. Configuration File in TFTP Server, with Dedicated IP Addressing Instead of DHCP/Bootp
To summarize the IP Preserve effect on IP addressing:
■
If the switch received its most recent VLAN 1 IP addressing from a DHCP/
Bootp server, it ignores the IP Preserve command when it downloads the
configuration file, and implements whatever IP addressing instructions
are in the configuration file.
■ If the switch did not receive its most recent VLAN 1 IP addressing from a
DHCP/Bootp server, it retains its current IP addressing when it downloads
the configuration file.
■ The content of the downloaded configuration file determines the IP
addresses and subnet masks for other VLANs.
