CSX Bridge View
Blocking This port is not forwarding or receiving trafÞc (and
therefore no physical address information is added to the
Filtering Database) nor is it sending or receiving BPDUs.
A port will enter the blocking state for two reasons: if it
receives information that another bridge is the
designated bridge to the network segment to which this
port is attached, or immediately after it has been enabled
by management.
Listening This state is entered from the blocking state when the
STA determines that this port should participate in frame
relay. The port is processing BPDUs, but is not yet
forwarding or receiving trafÞc or adding information to
the Filtering Database.
Learning The port is processing BPDUs, but is not yet relaying
packets. The port is adding address information to the
Filtering Database.
Forwarding A port enters this state from the Learning state. The port
is relaying frames and processing BPDUs. A port in this
state can enter the Disabled state by management.
Broken If the port is malfunctioning, this value will display in
the State Þeld.
This two-state button is active when you have bridge statistics displayed in the
Bridge Port entries (i.e., when Frames is selected); otherwise, it is grayed. When
you click on Delta, the Forward field in the Bridge Port entries displays the total
number of frames forwarded by this bridge port to another port on the bridge
during the last polling interval. When you click on Percentage, the Forward field
in the Bridge Port entries displays the percentage of all frames received by the
port from its network segment that were also forwarded to another port on the
bridge during the last polling interval.
The Detail View button lets you take a closer look at trafÞc between two, three, or
four selected bridge ports. The Detail View button is grayed unless you have at
least two bridge ports selected. For complete instructions on how to use the Detail
View, see the next section.
