Filter characteristics

IP filters apply to all routed IP packets to be forwarded through a switch on specified ingress ports. The filters are applied to the switch ingress ports with a default action to forward or drop. All packets not matching any filter are forwarded or dropped, depending on the port's default action.

Two types of filters that can be applied are described in the following sections:

• Global filters
• Traffic filters (source and destination)



Note: Filters are applied to a port using filter sets, and actions are assigned when applying a filter set to a port. The actions of individual filters can override the default actions of the port.

Filters on an Passport 8000 switch have the following characteristics and requirements:

• Global filter set lists must have an ID of 1 through 100 (100 total).
• Source and destination filter set lists must have an ID of 300 to 1000 (700 total).
  
  

  Note: You can have only a combined total of 128 global filter sets and source/destination filter sets.

  
  
• Source, destination, and global filter names do not have to be unique.
• A set of source/destination filters is defined in a list, and the list is applied to a port or set of ports. Multiple lists can be assigned to any given port.
• A set of global filters is defined in a list (not exceeding eight per list), and the list is applied to a port or set of ports. Multiple lists may be applied to a given port or set of ports, but the maximum number of global filters that can be enabled on a given port set is eight.
