ip address dhcp-alloc

Syntax
ip address dhcp-alloc
undo ip address dhcp-alloc
View
VLAN interface view
Parameters
None
Description
Use the ip address dhcp-alloc command to configure a VLAN interface to obtain an IP address
through DHCP.
Use the undo ip address dhcp-alloc command to cancel the configuration.
By default, a VLAN interface does not use DHCP to obtain an IP address.
To improve security and avoid malicious attacks to the unused sockets, S3600 Ethernet switches
provide the following functions:
UDP ports 67 and 68 used by DHCP are enabled/disabled only when DHCP is enabled/disabled.
The implementation is as follows:
After the DHCP client is enabled by executing the ip address dhcp-alloc command, UDP port 68
is enabled.
After the DHCP client is disabled by executing the undo ip address dhcp-alloc command, UDP
port 68 is disabled.
