IP Preserve: Retaining VLAN-1 IP Addressing Across Configuration File Downloads
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.
