Table 11.2: CLI Display of NAT Statistics

 

 

 

This Field...

 

Displays...

 

 

 

Total translations

 

The number of translations that are currently active. This number

 

 

changes when translations are added or age out. To display the

 

 

currently active translations, enter the show ip nat translation

 

 

command.

 

 

 

Hits

 

The number of times NAT searched the translation table for a NAT

 

 

entry and found the needed entry. (To optimize performance, NAT

 

 

looks in the NAT table for an existing entry for a given translation

 

 

before creating an entry for that translation.)

 

 

 

Misses

 

The number of times NAT did not find a needed entry in the translation

 

 

table. When this occurs, NAT creates the needed entry and places it

 

 

in the table.

 

 

 

Expired translations

 

The total number of dynamic translations that have aged of the

 

 

translation table since the HP device was booted.

 

 

 

Dynamic mappings

 

Lists the dynamic translation parameters configured for the device.

 

 

The following information is displayed:

 

 

• pool – The name of the pool from which the address used for the

 

 

translation was drawn.

 

 

• mask – The sub-net mask or prefix used for addressed in the

 

 

pool.

 

 

• start – The beginning (lowest) IP address in the pool.

 

 

• end – The ending (highest) IP address in the pool.

 

 

• total addresses – The total number of active address translations

 

 

that are based on addresses in this pool.

 

 

In addition, if the pool uses the Port Address Translation feature,

 

 

the word “overloaded” appears at the end of this row.

 

 

 

IP Fragments

 

Lists statistics for fragmented packets:

 

 

• saved – The number of out-of-sequence IP fragments saved.

 

 

• restored – The number of saved out-of-sequence IP fragments

 

 

that were successfully forwarded.

 

 

• timed out – The number of saved out-of-sequence IP fragments

 

 

that were dropped because the first IP fragment was never

 

 

received.
