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.
Configuring a single source IP address
Overview
This feature applies to the following software applications:
• RADIUS
• SFlow
• SNTP
• System Logging applications
• TACACS
• Telnet
• TFTP
The above IP-based software applications use a client-server communication model, that is, the
client’s source IP address is used for unique client identification. The source IP address is determined
by the system and is usually the IP address of the outgoing interface in the routing table. However,
routing switches may have multiple routing interfaces due to load balancing or routing redundancy,
