24-port NWay Ethernet Switch User's Guide
Some filtering is done automatically by the switch:
Dynamic filtering – automatic learning and aging of
MAC addresses and their location on the network.
Filtering occurs to keep local traffic confined to its
segment.
Filtering done by the Spanning Tree Protocol, which
can filter packets based on topology, making sure that
signal loops don' t occur.
Filtering done for VLAN integrity. Packets from a
member of a VLAN (VLAN 2, for example) destined
for a device on another VLAN (VLAN 3) will be filtered.
Some filtering
information into a filtering table:
MAC address filtering – the manual entry of specific
MAC addresses to be filtered from the network.
Packets sent from one manually entered MAC address
can be filtered from the network. The entry may be
specified as either a source, a destination, or both.
IP address filtering – the manual entry of specific IP
addresses to be filtered from the network (switch
must be in IP Routing mode). Packets sent from one
manually entered IP address to another can be filtered
from the network. The entry may specified as either a
source, a destination, or either (switch must be in IP
Routing mode).
