Enabling automatic edge detection
From the CEE interface, use this command to automatically identify the edge port. The port can
become an edge port if no BPDU is received.
To enable automatic edge detection on the 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 automatic edge detection on the CEE
interface. By default, automatic edge detection is
disabled.
switch(conf-if-te-0/1)#spanning-tree
autoedge
5. Display the spanning-tree configuration. switch(conf-stp)#do show
spanning-tree
