Command Manual (For Soliton) – DHCP
H3C S3100 Series Ethernet Switches
Chapter 2 Rate Limit Configuration Commands
2-3
Description
Use the
dhcp rate-limit
command to configure the maximum rate of DHCP traffic for
the port. When the number of DHCP packets received on the port per second exceeds
the specified threshold, the switch will discard the exceeding DHCP packets.
Use the
undo dhcp rate-limit
command to restore the default.
By default, after the DHCP traffic limit is enabled, the maximum rate of DHCP traffic is
15 pps.
Note that:
You need to enable the function to limit DHCP traffic (refer to the
dhcp rate-limit
enable
command) for a port before executing either of these two commands for the
port.
Examples
# Configure the DHCP traffic threshold to 100 pps for port Ethernet 1/0/11.

Description
Use the
dhcp rate-limit enable
command to enable the function to limit DHCP traffic
for an Ethernet port. You can use this command to limit the DHCP traffic passing
through an Ethernet port. When the number of DHCP packets received on the port per
second exceeds the specified threshold (the default value is 15 pps), the switch will
discard the exceeding DHCP packets.
Use the
undo dhcp rate-limit enable
command to disable the function. You can use
this command to relieve the DHCP traffic limit configured on an Ethernet port.
