Fwd Dly The number of seconds a non-edge Designated port waits until it can apply any
of the following transitions, if the RST BPDU it receives does not have an
agreed flag:
•
Discarding state to learning state
•
Learning state to forwarding state
When a non-edge port receives the RST BPDU it goes into forwarding state
within 4 seconds or after two hello timers expire on the port.
Fwd Dly is also the number of seconds that a Root port waits for an RST BPDU
with a proposal flag before it applies the state transitions listed above.
If the port is operating in 802.1D compatible mode, then forward delay
functionality is the same as in 802.1D (STP).
RSTP (IEEE 802.1W) Port Parameters
Port Num The port number shown in a slot#/port# format.
Pri The configured priority of the port. The default is 128 or 0x80.
Port Path Cost The configured path cost on a link connected to this port.
P2P Mac Indicates if the point-to-point-mac parameter is configured to be a
point-to-point link:
•
T – The link is configured as a point-to-point link.
•
F – The link is not configured as a point-to-point link. This is the default.
Edge port Indicates if the port is configured as an operational Edge port:
•
T – The port is configured as an Edge port.
•
F – The port is not configured as an Edge port. This is the default.
Role The current role of the port:
•
Root
•
Designated
•
Alternate
•
Backup
•
Disabled
Refer to “Bridges and bridge port roles” for definitions of the roles.
State The port’s current RSTP state. A port can have one of the following states:
•
Forwarding
•
Discarding
•
Learning
•
Disabled
Refer to “Bridge port states” and “Edge port and non-Edge port states” .
Designated Cost The best root path cost that this port received, including the best root path cost
that it can transmit.
Designated Bridge The ID of the bridge that sent the best RST BPDU that was received on this
port.
