Enter system view
Enable DHCP
Note:
To improve security and avoid malicious attacks to unused sockets, S5600 Ethernet
switches provide the following functions:
UDP port 67 and UDP port 68 ports used by DHCP are enabled only when DHCP is
enabled.
UDP port 67 and UDP port 68 ports are disabled when DHCP is disabled.
The corresponding implementation is as follows:
After DHCP is enabled with the dhcp enable command, if the DHCP server and
DHCP relay agent functions are not configured, UDP port 67 and UDP port 68 ports
are kept disabled; if the DHCP server or DHCP relay agent function is configured,
UDP port 67 and UDP port 68 ports are enabled.
After DHCP is disabled with the undo dhcp enable command, even if the DHCP
server or DHCP relay function is configured, UDP port 67 and UDP port 68 ports will
be disabled.
