New Feature Manual - DHCP
Quidway S3900 Series Ethernet Switches-Release 1510
Note:
To prevent malicious attacks to unused sockets and enhance security, S3900 series
Ethernet switches provide the following functions:
When DHCP is enabled, sockets UDP 67 and UDP 68 used by DHCP are enabled.
When DHCP is disabled, sockets UDP 67 and UDP 68 are shut down at the same
time.
The preceding functions are implemented as follows:
After you create a DHCP address pool by using the dhcp server ip-pool command,
sockets UDP 67 and UDP 68 will be enabled.
After you delete the DHCP address pool by using the undo dhcp server ip-pool
command and disable all the DHCP functions, sockets UDP 67 and UDP 68 will be
disabled.
Example
# Enter system view.
<Quidway> system-view
System View: return to User View with Ctrl+Z.
# Create DHCP address pool 0.
[Quidway] dhcp server ip-pool 0
[Quidway-dhcp-pool-0]
