Hi guys.
I want to obtain the ACE command equivalent to CSM variable TCP_WND_SIZE_OPTION command.

Thanks in advance!

Hi David,
So by default in ACE, TCP options are stripped before they are forwarded to server. To allow them you need to specify connection pmap.
tcp-options {range number1 number2 {allow | drop}} | {selective-ack | timestamp | window-scale} {allow | clear | drop}
So for allowing window scaling you need to do:
tcp-options window-scale allow
And for setting the scaling factor you need to use:
set tcp window-scale number
Pasting the document link for your reference:

Let me know if you have any questions.
Regards,
Kanwal
