Learning : The switch enters the Learning State if no path with a
higher priority is found during the Listening State. Learned entries are
entered in the Unicast Destination Forwarding Table. Normal data
is not transmitted.
Forwarding : The switch enters the Forwarding State after having been
in the Learning State for a predefined time period. Normal data is
transmitted.
Per port control settings
PathCost : Specifies the path cost for each port. The Spanning-Tree
Protocol uses port path costs to determine which port to select as a
forwarding port. You should assign lower numbers to ports attached to
faster media (such as full duplex), and higher numbers to ports attached
to slower media. The possible range is 1 to 65535. The recommended path
cost is 1000 divided by LAN speed in megabits per second.
Priority : Specify STP port priority for each port. The port (physical or
logical) with the lowest priority value has the highest priority and for-
wards the spanning-tree frames. The possible priority range is 0 through
255 (decimal). The default is 128. If all ports have the same priority value,
the lowest port number forwards the spanning-tree frames.
1.5.8 Port Sniffer Function
Port sniffer function is a method to duplicate all traffic occurred on the
specified monitored ports to the designated sniffer port. The traffic can
be configured for incoming packets only or outgoing packets only or
both. The control settings are:
Sniffer Mode : Specify the traffic type for monitoring
Options - Disable, Rx=incoming, Tx=outgoing, Both=Rx&Tx
Sniffer Port : Specify the port where performs monitoring
Monitored Port : Select the ports whose traffic will be duplicated to the
monitoring port. Press Space key for selection from the port member list.
