I have loaded an IOS update to a Cisco 3560 switch.  After loading and cleanup I have a directory left over from the old IOS that causes me problems, but I can't delete it or the sub directory or file in it.   Any suggestions would be appreciated.  Shown below is from the CLI.  c3560-ipservicesk9-mz.122-58.SE2.bin is the current IOS.  Ignore the file dates.  I had to do a password restore and load system defaults because the previous SA left a mess behind when he left.

I have been told that some manufacturers install a callback feature in their devices to track potential malfunctioning or mis-configured devices.  Is this feature installed in any Cisco Router, Switch and Firewall hardware or the IOS/firewall software?  If so, which hardware, software versions, and how does one find it? ...

Looking for ways to harden my edge, I found Document ID: 44541, Transit Access Control Lists: Filtering at Your Edge,  http://www.cisco.com/en/US/tech/tk648/tk361/technologies_white_paper09186a00801afc76.shtml. It was helpful, but a number of the ACL entries contained the operator/value "gt 1023,"  i.e. access-list 110 permit udp any gt 1023 host <primary DNS server&gt; eq 53, access-list 110 permit tcp host bgp_peer gt 1023 host router_ip eq bgp, and access-list 110 permit tcp host bgp_peer eq bgp host router_ip gt 1023. Since I also have a requirement to block ports, many of which are gt;1023,  I was wondering "what exactly does it do," "when do I need to use it," "why do I need it," and "how does it work?" I know that it does work, I just need some information on the what, when, why and how.  I looked on the support community site, but found no real answer.  Can anyone shine some light on this for me?
