    <description>&lt;P&gt;Hi all,&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;First, I apologize if this issue have been discussed earlier.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I have a PIX with dozens of access-list statements. I would like to simplify this list by using object-groups. F.ex:&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;In acl I have:&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;access-list acl-out permit icmp any any echo-reply&lt;/P&gt;&lt;P&gt;access-list acl-out permit icmp any any time-exceeded&lt;/P&gt;&lt;P&gt;access-list acl-out permit icmp any any unreachable&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Now when I create object-group for permitted icmp-types:&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;object-group icmp-type icmp-permitted&lt;/P&gt;&lt;P&gt;     icmp-object echo-reply&lt;/P&gt;&lt;P&gt;     icmp-object time-exceeded&lt;/P&gt;&lt;P&gt;     icmp-object unreachable&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;And then add a line to my acl:&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;access-list acl-out permit icmp any any object-group icmp-permitted&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Now this does not remove previously configured lines from my config...&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;So question is; is there some way to do this so that when I create object-group and add it to my acl all previously configured lines which are covered by this new line would be removed?&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thanks in advance,&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Saska&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;I guess, manually removing the earlier statements is the only way. I do not remember hearing of a mechanism where redundant ststements are removed automatically.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
