Global filters

Global filters may specify a source IP address and mask, a destination IP address and mask, both of these, or neither of these. Global filters have the following characteristics:

• No minimum or maximum mask length exists.
• Only one unique global filter of each source/address pair can be defined.
• Up to eight global filters can be applied on any given set of ARU ports. A set includes four ports, except for Gigabit ports, each of which can accommodate eight global filters.
• A global filter can cause the same actions as described above for source/destination filters.
