command
Parameter
Description
Switch(config)# interface [port_list]
[port_list]
Enter several discontinuous port
numbers separated by commas or a
range of ports with a hyphen. For
example:1,3 or 2-4
Switch(config-if-PORT-PORT)#
spanning-tree
Enable spanning-tree protocol on
the selected interfaces.
Switch(config-if-PORT-PORT)#
spanning-tree cost [0-200000000]
[0-
200000000]
Specify the path cost value on the
selected interfaces.
Switch(config-if-PORT-PORT)#
spanning-tree priority [0-15]
[0-15]
Specify priority value on the
selected interfaces.
0=0, 1=16, 2=32, 3=48, 4=64
5=80, 6=96, 7=112, 8=128
9=144, 10=160, 11=176,12=192
13=208, 14=224, 15=240
Switch(config-if-PORT-PORT)#
spanning-tree edge
Set the selected interfaces to edge
ports.
Switch(config-if-PORT-PORT)#
spanning-tree p2p [forced_true|
forced_fasle | auto]
[forced_true |
forced_fasle |
auto]
Set the selected interfaces to non-
point to point ports (forced_false) or
