ipv6 dhcp snooping rate-limit
Use ipv6 dhcp snooping rate-limit to specify the maximum rate at which an interface can receive
DHCPv6 packets.
Use undo ipv6 dhcp snooping rate-limit to remove the rate limit.
Syntax
ipv6 dhcp snooping rate-limit rate
undo ipv6 dhcp snooping rate-limit
Default
Incoming DHCPv6 packets on an interface are not rate limited.

Parameters
rate: Specifies the maximum rate for an interface to receive DHCPv6 packets, in Kbps. The value
must be an integer multiple of 8, in the range of 64 to 512.
Usage guidelines
This command takes effect only when DHCPv6 snooping is enabled.
The DHCPv6 packet rate limit feature enables the interface to discard DHCPv6 packets that exceed
the maximum rate.
If you configure this command 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 configured
on the Layer 2 aggregate interface. If the Layer 2 Ethernet interface leaves the aggregation group, it
uses its own DHCP packet maximum rate.
Examples
# Specify Ten-GigabitEthernet1/0/1 to receive DHCPv6 packets at a maximum rate of 64 Kbps.
