Hi all,

In 
draft-ietf-ipcdn-device-mibv2-01.txt              

I think the definition for docsDevFilterIpSourcePort and equivalent MIBs should be clarified that
in the case that docsDevFilterIpProtocol is set to "all", the port numbers need to be checked for 
matching if the traffic is udp or tcp as udp and tcp are included in "all", this is not clear from the current definitions. Cable operators typically want to block all TCP/UDP ports below a certain port-number, they will use any protocol, and put one port-range in. 

docsDevFilterIpSourcePortLow OBJECT-TYPE
           SYNTAX      Integer32 (0..65535)
           MAX-ACCESS  read-create
           STATUS      current
           DESCRIPTION
               "If docsDevFilterIpProtocol is udp or tcp, this is the
                inclusive lower bound of the transport-layer source port
                range that is to be matched, otherwise it is ignored
                during matching."
           DEFVAL { 0 }
           ::= { docsDevFilterIpEntry 12 }

Any comments ?

Thanks,
  Best regards,
