DLSW: what does max-lf mean output by sh dlsw reach

Hi everyone,

Customer asked me what does "max-lf" mean displayed by "show dlsw reachability" command.

Following is the result of "show dlsw reachability" command.

xxxx.yyyy.zzzz FOUND REMOTE xxx.xxx.xxx.xxx(2065) max-lf(4472)

yyy.yyy.yyy.yyy(2065) max-lf(4472)

I understand max-lf means the max largest frame size (in bytes).

And this remote peer (in this case, xxx.xxx.xxx.xxx and yyy.yyy.yyy.yyy) can use frame size

on a circuit up to max-lf without segmenting/fragmenting the frame

So in this case, "4472" means the max largest frame size for those remote peers.

Is my understanding true ?

And what does "2065" means ?

Are those values (4472 and 2065) configured automatically unless customer does not

configured "dlsw remote-peer" with "lf" size option.

Would you please let me know about my question.

Your information would be appreciated.

Best regards,

max-lf describes the largest frame and I believe that the 4472 is a default value.

2065 is the TCP port number used to carry DLSW. It is not related to largest frame in any way.
