354.0. "Can IRIS do Wildcard MAC Octet Matching?" by DAVIDF::FOX (David B. Fox -- DTN 285-2091) Thu Apr 03 1997 15:32

    Was wondering if IRIS could do the following:
    
    The new VNswitch units come preset with a "group" MAC address.  For
    example, 00-00-F8-64-B8-00.  Depending on how you have the switch
    configured, the last 00 octet is changed to be something unique.
    
    Is there any way to have IRIS address filter with a wildcard last
    octet?  If not, could we add it to the wish list?
    
    	Thanks!

    You bet!  That feature was put in quite some time ago, but it's 
    probably not documented well.
    
    Put X's in for the digits you don't care about:
    
    
    	0000F864B8XX will match any last digit.

    wildcard other and or more digits too.
