72 Internet Protocol (IP) Enhancements Release Note

Description This command adds a pattern to an IP traffic filter, policy filter, routing filter, or priority filter. You now specify the type of filter by using the type parameter.

Parameter	Description
FILter	The filter number, from 0 to 999, that the pattern is added to. When
	the type parameter is not specified, the router or switch may use the
	filter number to help determine the filter type. See the description of
	the type parameter for further details.
	Default: no default
TYPE	The type of filter the router or switch creates. When type is not
	specified, the router or switch determines the filter type based on the
	IP filter number and the specified parameters:
	Filters with a specified policy parameter are policy filters.
	Filters with a specified priority parameter are priority filters.

Filters with a specified action parameter are either traffic or routing filters. If the filter number set is:

•between 0 to 99, they are traffic filters

•between 100 to 999, they are routing filters, as long as the only other parameters specified are the source, entry and smask parameters. If any other parameter is specified the filter is a traffic filter.

We recommend always defining this parameter, as a traffic filter created without specifying type=traffic, and with a filter number between 100 and 999, can default to a routing filter.

See these sections in the IP chapter of the Software Reference for more information about using traffic, policy and priority filters:

•“Traffic Filters”

•“Policy-Based Routing“

•“Priority-Based Routing“ Default: see the above description

TRAFfic	A traffic filter is created. The action parameter must
	also be specified.
POLicy	A policy filter is created. The policy parameter must
	also be specified.
PRIority	A priority filter is created. The priority parameter
	must also be specified.
ROUting	A routing filter is created. The action parameter
	must also be specified.

disable ip macdisparity

Syntax DISable IP MACdisparity

Description This new command stops ARP entries from being configured with discrepancies in their address. When disabled, the router or switch will not allow an ARP entry with a multicast MAC address to be added, and the router or switch will discard packets received with address discrepancies.

Example To ensure that entries with unicast IP addresses do not get assigned a multicast MAC address, use the command:

dis ip mac
