Do a config block. Make the start of the config block be:
^interface FastEthernet .*\r\n description Managed by HP SA. Installation=.*
and the end of the config block be
^\!
Then, check for your "switchport access vlan 99" in the contents of the block.
Should work, if not, post a screenshot of what you're doing and I'll look at it. Oh, you might change the space before the " description" to "\s+description", although I think the first should work ok...
