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).
Hello
The hello value derived from the Root port. It is the number of
seconds between two Hello packets.
Port IEEE 802.1W 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” on page 7-19 for definitions
of the roles.
