Transparent tab

The Transparent tab contains information about a specific unicast MAC address,
which has some forwarding information for the bridge.

Description
Value (in hundredths of a second) that controls how fast a
port changes its spanning state when moving towards the
Forwarding state. The value determines how long the port
stays in each of the Listening and Learning states, that
precede the Forwarding state. The value is also used
when a topology change has been detected and is
underway. This ages all dynamic entries in the
Forwarding Database.
Note: This value is the one that this bridge is currently
using, in contrast to dot1dStpBridge ForwardDelay which
is the value that this bridge and all others would start
using if/when this bridge were to become the root.]
Value that all bridges use for the maximum age of a
bridge when it is acting as the root.
Note: 802.1D-1990 specifies that the range is related to
the value of BridgeHelloTime. The granularity of this timer
is specified by 802.1D-1990 to be 1 second. A badValue
error may be returned if the value set is not a whole
number.
Value that the bridge uses for HelloTime when the bridge
is acting as the root. The granularity of this timer is
specified by 802.1D- 1990 to be one second. An agent
may return a badValue error if a set is attempted to a
value that is not a whole number of seconds.
Value that all bridges use for ForwardDelay when this
bridge is acting as the root.
Note: 802.1D-1990 specifies that the range for this
parameter is related to the value of
dot1dStpBridgeMaxAge. The granularity of this timer is
specified by 802.1D-1990 to be one second. An agent
may return a badValue error if a set is attempted to a
value that is not a whole number of seconds.
