Operation
Enter system view
Enable DHCP
Note:
To improve security and avoid malicious attack to the unused SOCKETs, S3600
Ethernet switches provide the following functions:
UDP 67 and UDP 68 ports used by DHCP are enabled only when DHCP is enabled.
UDP 67 and UDP 68 ports are disabled when DHCP is disabled.
The corresponding implementation is as follows:
After DHCP is enabled by executing the dhcp enable command, if the DHCP server
and DHCP relay functions are not configured, UDP 67 and UDP 68 ports are kept
disabled; if the DHCP server / DHCP relay function is configured, UDP 67 and UDP
68 ports are enabled.
After DHCP is disabled by executing the undo dhcp enable command, even if the
DHCP server and DHCP relay functions are configured, UDP 67 and UDP 68 ports
will be disabled.

2.2.3 Configuring Global Address Pool Mode on Interface(s)

You can configure the global address pool mode on the specified or all interfaces of a
DHCP server. After that, when the DHCP server receives DHCP packets from DHCP
clients through these interfaces, it assigns IP addresses in the global address pool to
the DHCP clients.
