Parameters
all: Configures to control both the number of NAT connections and the connection
setup rate.
amount: Configures to control the number of NAT connections.
rate: Configures to control the connection setup rate.
 Note:
The connection here refers to an address mapping established during NAT, and
connection setup rate refers to the rate at which NAT connection is established.
Description
Use the nat blacklist mode command to set the control mode of the NAT blacklist
feature, thus using the feature to control the number of NAT connections, the
connection setup rate, or both.
Use the undo nat blacklist mode command to cancel the setting of NAT blacklist
control mode.
Caution:
z Each command that is used to modify blacklist-related configuration and is not
source IP address-specific must be coupled with the reset nat session command.
z Although each blacklist-enabled LPU in the switch independently maintains its own
blacklist information, blacklist-related configuration commands executed on the
switch apply to all LPUs.
