NAT Configuration Commands
1-13
Caution:
z With the nat blacklist limit amount source user-ip command, you can set different
specific thresholds to limit the NAT connection quantities of different specified users.
While, with the nat blacklist limit rate source ip command, the specific thresholds
you set to limit connection setup rate are for all specific users (users specified by the
nat blacklist limit rate source user-ip command), and you cannot set different
thresholds for different specific users.
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.
Examples
# Set the specific CIR, CBS and EBS control thresholds to 100, 500 and 40
respectively.
