speed {10 | 100 | 1000 } 
  Bold indicates an unalterable keyword. For example: show logging 
  Normal Font indicates a constant (several options are enumerated  and only one can be 
selected). For example: mode {dynamic | static | permanent} 
  Italic Font indicates a variable (an actual value must be assigned). For example: bridge 
aging-time

1.4.2  Special Characters 
You should pay attentions to the description below if the variable is a character string: 
  These six characters ” < > , \ & can not be input. 
  If a blank is contained in a character string, single or double quotation marks should be 
used, for example ’hello world’, ”hello world”, and the words in the quotation marks will be 
identified as a string. Otherwise, the words will be identified as several strings.

choosing port 1/0/1,1/0/3,1/0/4,1/0/5,1/0/7.
