| Description | This object indicates how the port is to be used.
The variable usage applications are shown above.
These applications are defined such that they
are mutually exclusive. In other words, a port
using the security(2) application cannot also
use the monitor(3) application at the same time.
The default usage is standard(1), or no special
behavior (the port behaves as normal
switched port).
The security(2) usage adds addressing security
to the port, whereby all learned addresses are
secure address.
The monitor(3) usage provides network diagnosis
by reflecting traffic on other ports to this port.
The portGrouping(4) application treats this and other ports in
the same group as one(inter-switch) connection for more
bandwidth potential. When the c2900PortUsageApplication is
portGrouping, the c2900PortGroupIndex is set to the index
value of the port group. The source address of a received frame
is used to determine on which port within the group the frame
should be transmitted.
The network(5) usage saves address table space when the port
is used as the link to a large network with many MAC addresses
by disabling address learning on the port and allowing
unknown unicasts packets received on other ports of the vlan
the port associated with to be forwarded only to the port.
The networkGroup(6) usage treates this and other
ports in the same group as a network port group. All ports in
port are network ports in the sense that address learning is
disabled on them and unknown unicast packets received on other
ports of the vlan are forwarded to the group.
The portGroupDest(7) application treats this and other ports in
the same group as one(inter-switch) connection for more
bandwidth potential. When the c2900PortUsageApplication is
portGroupDest, the c2900PortGroupIndex is set to the index
value of the port group. The destination address of a received
frame is used to determine on which port within the group the
frame should be transmitted.
The protected(8) application does not forward any traffic to other
protected ports. It does not forward all kinds of unicast, multicast
and broadcast traffic to any other protected port. The protected
ports, however, forward traffic normally to non-protected ports and
vice versa. |
