To enable port fast on a CEE interface, perform the following steps:
Specifying the port priority
From the CEE interface, use this command to specify the port priority.
To specify the port priority on a CEE interface, perform the following steps:
Step Task Command
1. Enter global configuration mode. switch>#config t
Enter configuration commands, one
per line. End with CNTL/Z.
switch(config)#
2. Specify the CEE interface (interface 0/1 is used in
this example).
switch(config)#interface
tengigabitethernet 0/1
switch(conf-if-te-0/1)#
3. Enable the CEE interface. switch(conf-if-te-0/1)#no shutdown
switch(conf-if-te-0/1)#
4. Enable port fast on a CEE interface. Port fast is
disabled by default. Syntax is as follows:
• bpdu-filter—Sets the port-fast BPDU filter for
the port. BPDU filtering allows you to avoid
transmitting BPDUs on PortFast-enabled ports.
• bpdu-guard—Guards the port against the
reception of BPDUs. The BPDU guard prevents
loops by moving a nontrunking port into an
errdisable state when a BPDU is received on
that port.
switch(conf-if-te-0/1)#spanning-tree
portfast {bpdu-filter | bpdu-guard}
5. Display the spanning-tree configuration. switch(conf-stp)#do show
spanning-tree
Step Task Command
1. Enter global configuration mode. switch>#config t
Enter configuration commands, one
per line. End with CNTL/Z.
switch(config)#
2. Specify the CEE interface (interface 0/1 is used in
this example).
switch(config)#interface
tengigabitethernet 0/1
switch(conf-if-te-0/1)#
3. Enable the CEE interface. switch(conf-if-te-0/1)#no shutdown
switch(conf-if-te-0/1)#
4. Specify the port priority on a CEE interface. The
range is 0 through 240 in increments of 16. The
default is 128.
switch(conf-if-te-0/1)#spanning-tree
priority priority
5. Display the spanning-tree configuration. switch(conf-stp)#do show
spanning-tree
