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 can be applied:

• 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 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.
