Default
The default is Disabled.
Command Mode
Interface Config
8-153 ipv6 dhcp snooping limit
Controls the rate at which the DHCP Snooping messages arrive at a specific interface or a range of
interfaces. Rate limiting is disabled by default. When rate limiting is enabled, the allowable rate can range
from 0 to as high as 300 packets per second. The allowed range for the burst level is 1 to 15 seconds.
The configuration of rate limiting occurs on a physical port, and it may be applied to both trusted and
untrusted ports.
The
no
command resets the rate at which the DHCP Snooping messages arrive, as well as the burst
level, to the default values.
ipv6 dhcp snooping limit {rate 0-300 [burst interval seconds]}
no ipv6 dhcp snooping limit
Parameters
rate
Configure rate limit in pps (0-300).
burst interval seconds
(Optional) Indicates the burst interval in seconds.
Default
The default is Disabled (no limit).
Command Mode
Interface Config
8-154 ipv6 verify source
Configures the lPv6SG source ID attribute so that it filters the data traffic in the hardware. The source ID
consists of a combination of the IP address and MAC address. Normal command makes data traffic
filtration based on the IP address possible. With the “port-security” option, meanwhile, the filtering of data
traffic is conducted based on the IP and MAC addresses.
Please note that this command can be used to configure either a specific interface or a range of
interfaces.
The
no
command disables the IPv6SG configuration in the hardware. The port-security cannot be
disabled alone if it is configured.
