Description
Use the dhcp relay server-detect command to enable unauthorized DHCP server detection.
Use the undo dhcp relay server-detect command to disable unauthorized DHCP server detection.
By default, unauthorized DHCP server detection is disabled.
With this function enabled, upon receiving a DHCP request, the DHCP relay agent will record from the
request the IP addresses of all DHCP servers that ever offered IP addresses to the DHCP client and the
receiving interface. Each server detected is recorded only once. The administrator can get this information
from logs to check out unauthorized DHCP servers.
After the information of recorded DHCP servers is cleared, the relay agent will re-record server
information following this mechanism.
