The meaning of a flag display of sho ip nat translations verbose command.

Hi all.

I would like to know about the meaning of a flag display of sho ip nat

translations verbose command. It is flag part of the following description.

# sho ip nat trans verbose

Pro Inside global Inside local Outside local Outside global

tcp 172.17.102.180:21 10.1.1.1:21 172.17.102.110:3125

172.17.102.110:3125

create 00:00:27, use 00:00:26, left 23:59:33, flags: extended, use_count: 0

--- 172.17.102.180 10.1.1.1 --- ---

create 00:00:27, use 00:00:20, left 23:59:39, flags: outside, use_count: 1

A kind of Flag is extend,static,destination and outside,timeout.

In Document, the meaning of each flag is explained as follows.

Indication of the type of translation. Possible flags are:

Extended-Extended translation

Static-Static translation

Destination-Rotary translation

Outside-Outside translation

Timing out-Translation will no longer be used, due to a TCP finish (FIN) or reset (RST) flag.

I want to know which state that is Extended translation and Outside translation indicates on traffic flow.

Please, teach me that.

Thanks,best regards.

Extended is Overloaded or PAT translations. One to many.

Statics is one-to-one mapping of translation.

Destination is round robin translation for load sharing

Outside is translating something outside to another address inside.

Timing out is when a socket is terminated gracefully or abruptly.

Hope this helps.
