flood (VLANs)


Hierarchy Level


Apply a flood filter to traffic ingressing a VLAN. Flood filters are triggered only for broadcast, unknown unicast, and multicast (BUM) traffic.

Flood filters and firewall filters can coexist on the same VLAN. If the actions in the filters are conflicting, then the firewall filter takes priority over the flood filter.


All incoming traffic is accepted unmodified to a VLAN, and all outgoing traffic is sent unmodified from a VLAN.
