IPv4 Filter Expansion

This Software Version increases the amount of IP filters you can create, and
allows you to assign a filter type to any IP filter.
You can now create up to 1000 IP filters by using the add ip filter command.
Previously, you could create a maximum of 400 IP filters. The number range
you can now specify in the add ip filter command is 0 to 999. The type of filter
created is no longer associated with the IP filter number, so you can allocate
any filter type to any filter number.
Use the type parameter in the add ip filter command to define the filter type.
Previously, the filter type was determined by the range of numbers you set the
filter number in.
The type parameter lets you assign IP filters as traffic, policy, priority or
routing filters, regardless of the filter number. This allows you to create as
many IP filters of a specific type as you may need. Use the type parameter:
add ip filter=0..999 source=ipadd
{action={include|exclude}|policy=0..15|priority=p0..p7}
[type={traffic|policy|priority|routing}]
The type parameter is optional, to ensure that this Software Version is
backwards compatible with configuration scripts written using an earlier
Software Version. When type is not specified, the router or switch determines
the filter type based on the value of the 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 the action parameter specified 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 using the type parameter to define the filter type. This
is particularly important when you are creating traffic filters with a filter
number between 100..999, as these can default to routing filters if type has no
value set. Routing filters are only used in conjunction with Border Gateway
Protocol (BGP). However, even if BGP is not available on your router or switch
you can still create a routing filter.
As with previous Software Versions, you cannot change the type of filter, or the
number assigned to the filter with the set ip filter command.
