Nat Blacklist Start - H3C S9500 Series Command Manual

Command Manual – NAT
H3C S9500 Series Routing Switches
Parameters
None
Description
Use the nat auto-reset-session command to enable the NAT session table auto-reset
function when a NAT enabled VLAN interface goes up or down.
Use the undo nat auto-reset-session command to disable the function.
By default, the NAT session table auto-reset function is disabled.
After you execute this command, the NAT session table is reset only when a
NAT-enabled VLAN interface goes up or down.
This function is typically used in link backup networks. When the active link is down, the
corresponding NAT session table is cleared. Then, NAT configured on the backup link
performs address translation for packets.
Because all NAT session tables are cleared when a NAT enabled VLAN interface goes
up or down, you are not recommended to enable this function in a common network.
Examples
# Enable the NAT session table auto-reset function when the VLAN interface goes up
or down.
