SSL Profile Error

I am trying to create a ssl profile using the below command and F5 is throwing an error. Please help me in finding out where the error is. We are on 11.5.3.

create ltm profile client-ssl test-dev-isne-ssl-profile { app-service none cert test-dev.abc.com.crt cert-key-chain { test-dev.abc.com_test-dev.abc.com { cert test-dev.abc.com.crt key test-dev.abc.com.key } } chain none defaults-from clientssl inherit-certkeychain false key test-dev.abc.com.key options { dont-insert-empty-fragments no-sslv2 no-sslv3 } passphrase "****" } Syntax Error: "cert-key-chain" unexpected argument "{" one of the following must be specified: add, delete, modify, replace-all-with
