NAME
       udp-portlist - Configures the DoS udp portlist component within the security dos module using the syntax shown
       in the following sections. These DoS udp portlist entries are applied to all udp packets except those going
       through the management interface.

MODULE
       security dos

SYNTAX
   MODIFY
	modify udp-portlist dos-udp-portlist

	  description [string]
	  list-type [exclude-listed-ports | include-listed-ports]
	  entries [modify | replace-all-with] {
	     [entry] {
	       options:
		description [string]
		match-direction [both | dst | none | src]
		port-number [number]
	     }
	  }

   DISPLAY
	list udp-portlist

DESCRIPTION
       You can use the udp-portlist component to configure a DoS UDP portlist of upto eight entries for all UDP
       traffic except the management interface.  The HSB hardware compares all incoming UDP traffic to the udp-
       portlist entries.  There are 2 types of behavior, depending upon whether the udp port list is configured as a
       white list or as a black list. White list and black list are mutually exclusive properties of a UDP port list.

       If the udp port list is configured as a list-type of exclude-listed-ports, and if a match is found on an
       incoming packet, then we do not increment the UDP Flood DoS vector.  If a match is not found, then the UDP
       Flood DoS vector checks are done on those packets.

       If the udp port list is configured as a list-type of include-listed-ports, and if a match is found on an
       incoming packet, then we increment the UDP Flood DoS vector. If a match is not found, then the UDP Flood DoS
       vector checks are not done on the packets.

       Either destination port or source port or both can be specified in a udp-portlist entry.

EXAMPLES
       modify udp-portlist dos-udp-portlist description "bad ports" list-type include-listed-ports Modifies the udp-
       portlist dos-udp-portlist to a blacklist.

       modify udp-portlist dos-udp-portlist list-type exclude-listed-ports Modifies the udp-portlist dos-udp-portlist
       to a white-list.

       modify udp-portlist dos-udp-portlist description "bad ports" entries modify { entry1 { match-direction src
       port-number 161 } } Modifies an entry. The new entry is for source UDP port 161. It matches any UDP packet
       whose source port is 161.

       modify udp-portlist dos-udp-portlist entries modify { 161 { match-direction both } }

       Modifies the entry for destination UDP port 161 to source and destination port 161. It matches any UDP packet
       whose destination or source port is 161.

	security dos udp-portlist dos-udp-portlist {
	   entries {
	       entry1 {
		   match-direction both
		   port-number snmp
	       }
	       entry2 { }
	       entry3 { }
	       entry4 { }
	   }
	   white-list
	}

       Displays the current list of DoS UDP portlist entries.

OPTIONS
       description
	    Your description for the DoS udp-portlist.

       list-type
	    Sets the list type to be either exclude-listed-ports or include-listed-ports

	    include-listed-ports
		 Sets the property of the dos-udp-portlist list to include-listed-ports (Blacklist).

	    exclude-listed-ports
		 Sets the property of the dos-udp-portlist list to  exclude-listed-ports (Whitelist).

       entries
	    Modifies a udp-portlist entry.

	    modify
		 Modifies the existing entry that you specify next, in curly braces ({}).  After the entry name,
		 enter the new configuration (port mode and port number) settings for the entry inside a nested set
		 of curly braces.

	    replace-all-with
		 Replaces the current set of udp-portlist entries with the entry(s) that you specify next, in curly
		 braces ({}).

	    Enter the name of a entry to be  modified, then enter an open curly brace ({), one or more of the
	    following options, and a closed curly brace (}).

	    description
		 Your description for the current entry.

	    match-direction
		 Set the mode of matching (source, destination or both).

	    port-number
		 Set the port number for matching.
