Description The
config stp ports
command configures STP for a group of ports.
Parameters
<portlist>
−
Specifies a range of ports to be configured. The port list
is specified by listing the lowest switch number and the beginning
ort number on that switch, separated by a colon. Then the highest
r, and the highest port number of the range (also
colon) are specified. The beginning and end of the
port list range are separated by a dash. For example, 1:3 specifies
ch number 1, port 3. 2:4 specifies switch number 2, port 4. 1:3-
cifies all of the ports between switch 1, port 3 and switch 2,
