Configure An Edgeport - Dell Force10 MXL Blade Configuration Manual

Table 19-2. MSTP Default Port Cost Values
Port Cost
Port Channel with two 10-Gigabit Ethernet interfaces
Port Channel with two 40-Gigabit Ethernet interfaces
To change the port cost or priority of an interface, use the following commands:
Task
Change the port cost of an interface.
Range: 0 to 2000000
Default: refer to Table 19-2.
Change the port priority of an interface.
Range: 0 to 240, in increments of 16
Default: 128
To view the current values for these interface parameters, use the
mode (Figure 19-9).

Configure an EdgePort

The EdgePort feature enables interfaces to begin forwarding traffic approximately 30 seconds sooner. In
this mode, an interface forwards frames by default until it receives a BPDU that indicates that it should
behave otherwise; it does not go through the Learning and Listening states. The
shutdown-on-violation
you only implement
the BPDU, the physical interface remains up and spanning-tree drops packets in the hardware after a
BPDU violation. BPDUs are dropped in the software after receiving the BPDU violation. This feature is
the same as PortFast mode in Spanning Tree.
Caution:
Configure EdgePort only on links connecting to an end station. EdgePort can cause loops if you enable it
on an interface connected to a network.
The enabling of BPDU Filtering stops sending and receiving of BPDUs on the port fast enabled ports.
When both BPDU guard and BPDU filter are enabled on the port, BPDU filter takes the higher precedence.
By default, BPDU filtering on an interface is disabled.
To enable EdgePort on an interface, use the following command:
Task
Enable EdgePort on an interface.
