Network Setup 4-163
AdminPort PortFast
Bpdu Guard
Displays the whether BPDU Guard is currently enabled for this port.
When set for a bridge, all PortFast-enabled ports having the
bpdu-guard set to default shut down the port on receiving the BPDU. When this
occurs, the BPDU is not processed.
OperPort PortFast
Bpdu Guard
Displays the whether BPDU Guard is currently enabled for this port.
When the OperPort PortFast BPDU Guard feature is set for a bridge, all PortFast-
enabled ports that have the bpdu-guard set to default shut down the port on
receiving a BPDU. When this occurs, the BPDU is not processed.
Port Version Displays the port version associated with this instance. It can be either of the
following:
•STP
• RSTP
• MSTP
Port State Port State displays the MSTP state for this port. A port must be enabled to be able
to forward.
Port Enable Displays the enable/disable MSTP designation of each port. A green check mark
indicates the Oper MAC Enable status is active/enabled.
Port Path Cost Port Path Cost displays the path cost for the specified port index. The default path
cost depends on the speed of the interface.
Speed Default path cost
<=100000 bits/sec 200000000
<=1000000 bits/sec 20000000
<=10000000 bits/sec 2000000
<=100000000 bits/sec 200000
<=1000000000 bits/sec 20000
<=10000000000 bits/sec 2000
<=100000000000 bits/sec 200
<=1000000000000 bits/sec 20
>1000000000000 bits/sec 2
Port Designated Cost Displays the port cost for each port on the switch. The cost helps determine the role
of the port in the MSTP network. The designated cost is the cost for a packet to
travel from this port to the root in the MSTP configuration. The slower the media,
the higher the cost.
Designated Port Defines the port connection used to send and receive packets. By having only one
designated port per segment, all looping issues should be resolved. Once the
designated port has been selected, any other ports that connect to that segment
become non-designated ports and block traffic from taking the defined path.
Forward Transitions Forward Transitions displays the number of MSTP state transitions to the
forwarding state that have occurred on this port.
Protocol Migration The switch can interoperate with legacy 802.1d bridges running STP / RSTP. If the
port receives a legacy 802.1D configuration BPDU, it only sends 802.1D BPDUs over
its port from that point on. Enable this option to restart detection of whether the
port is connected to an MSTP capable bridge or a legacy 802.1 bridge.
Admin Edge Port A green checkmark defines the listed index enabled as an Admin Edge Port, and a
red “X” defines the listed index as not being an Admin Edge Port. Enable it only on
ports that connect to a single location.
