Use this command to configure the IPv4 NAT maximum number of translation entries.
| number | Specifies the maximum number of translation entries allowed for this router. Default value of 0 (no-limit). Valid values: 1 - 65535. |
The maximum number of translation entries defaults to 0 (no-limit).
Configuration command, Global configuration.
65535 entries is currently the maximum value allowed for this command. Certain applications such as NAT, LSNAT, TWCB share the same hardware resource pool of 65535 bindings on a first come first serve basis. Lowering this value assures resources will be available for other applications.
The “no” form of the command resets the number of maximum entries to the default value of 0 (no-limit).
This example sets the maximum number of NAT translation entries to 20000:
System(rw-config)->ip nat translation max-entries 20000
