摘要： A method for assigning identifiers to switches in a stack includes detecting, by a switch, a terminal identifier stored in an optical module that is connected to a stack port of the switch, where the optical module is at one end of an optical cable; and if a condition is met, assigning, by the switch, identifiers to N stackable switches along a direction starting from the switch to another switch connected to the stack port, where the condition includes: a value of the terminal identifier is a specified value, and N is greater than or equal to 2. According to this application, an efficiency of assigning the identifiers to the switches in a stack can be improved.
