Method and Apparatus for indicating port states at a packet switch |
摘要 |
The present invention discloses a method for indicating port states and a switch. A main panel of the switch is provided with port indicators one-to-one corresponding to physical ports and N channel indicators. The switch further includes a main chip and a control component. The control component is configured to: receive a port state indication signal from the main chip, and parse the port state indication signal to obtain usage state information of each logical port; generate N enable signals, and control at most one enable signal to be valid at any time point; and control the states of the N channel indicators by using the N enable signals sent from the enable signal controlling module, and control the state of each port indicator according to the N enable signals and the usage state information of each logical port. |
