merge verify file - "ltm" unknown property

Hi,

I'm hoping there is a nice quick answer for this, I'm trying to verify configuration that has been migrated from a Cisco ACE to LTM and I get the following error when executing

load sys config merge file /var/tmp/config.file verify
Validating configuration...
  /var/tmp/config.file
Syntax Error:(/var/tmp/config.file at line: 97) "ltm" unknown property

What us puzzling me is that line 97 contains a simple SSL profile config, almost identical to the 96 lines above:

ltm profile client-ssl SSL-PROFILE-1 {
    defaults-from /Common/DEFAULT-PROFILE-1
    key KEY.key
    cert CRT.crt
    chain CHAIN.crt
}

Any ideas why TMSH doesn't like the "ltm" command!!?

Thanks MP
