Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Set the maximum rate at
which an interface can
receive DHCPv6
packets.
ipv6 dhcp snooping
rate-limit rate
By default, incoming DHCPv6 packets on an
interface are not rate limited.
You can configure this command only on Layer
2 Ethernet interfaces and Layer 2 aggregate
interfaces.
If you set the maximum rate on a Layer 2
Ethernet interface that is a member port of a
Layer 2 aggregate interface, the Layer 2
Ethernet interface uses the DHCP packet
maximum rate set on the Layer 2 aggregate
interface. If the Layer 2 Ethernet interface
leaves the aggregation group, it uses its own
DHCP packet maximum rate.
Displaying and maintaining DHCPv6 snooping
Execute display commands in any view, and reset commands in user view.

DHCPv6 snooping configuration example
Network requirements
As shown in Figure 81 , configure GigabitEthernet 1/0/1 connecting to the DHCPv6 server as a trusted
port. Enable DHCPv6 snooping to record client information in DHCPv6 snooping entries.
