Abstract
Using a hash function, an L2/L3 switch can produce an FID for a data packet. The L2/L3 switch can select, from among potentially several stored VLAN flooding tables, a particular VLAN flooding table that is associated with a particular VLAN on which the data packet is to be carried. The rows of the particular VLAN flooding table can specify different combinations of the particular VLAN's egress ports. The L2/L3 switch can locate, in the particular VLAN flooding table, a particular row that specifies the FID. The L2/L3 switch can read, from the particular row, a specified subset of the egress ports that are associated with the particular VLAN. The L2/L3 switch can transmit copies of the data packet out each of the egress ports specified in the subset, toward analytic servers connected to those egress ports.
