ed by listing the lowest switch number and the beginning port
number on that switch, separated by a colon. Then the highest
mber, and the highest port number of the range (also
a colon) are specified. The beginning and end of the
port list range are separated by a dash. For example, 1:3 specifies
switch number 1, port 3. 2:4 specifies switch number 2, port 4. 1:3-
2:4 specifies all of the ports between switch 1, port 3 and switch 2,
