Abstract

A system and method for switch management includes a switch including a plurality of switch modules, and a status display panel. The plurality of switch modules includes one or more power supply modules for providing power to the switch, one or more cooling modules for cooling the switch, and one or more switching modules. The switch is configured to detect the plurality of switch modules, interrogate the detected switch modules, hierarchically organize status information based on information associated with the interrogated switch modules, and display the organized status information on the status display panel. The status information is displayed on the status display panel using an interactive status display system. In some examples, the switch further includes a plurality of status indicators, and the switch is further configured to temporarily activate the status indicators in response to active use of the status display system.

Claims

1. A method for managing a switch, the method comprising:

exchanging, by a first module of the switch, one or more messages with one or more detected modules of the switch to determine status information associated with each of the one or more detected modules, and a type of each of the one or more detected modules, wherein the first module is selected from a group of modules consisting of a switching module, a route processing module (RPM), and a cooling module;

determining a hierarchy among the one or more detected modules of the switch based on the determined type of each of the modules of the switch;

organizing the status information associated with each of the one or more detected modules of the switch consistent with the determined hierarchy;

displaying the organized status information on a status display panel mounted on the first module of the switch on a plurality of status display screens, each of the status display screens displaying information at a corresponding level of the hierarchy and having one or more user interface elements for navigating between a current status display screen at a first level of the hierarchy to one or more of the status display screens at other levels of the hierarchy; and

managing, by an operator, the switch using the organized status information displayed on the status display panel.

2. The method of claim 1, further comprising detecting a fault in one of the one or more detected modules of the switch, the fault selected from a group consisting of insufficient cooling, insufficient power, loss of communication, and switch failure.

3. The method of claim 2, further comprising detecting insufficient cooling in response to installation of a new module in the switch.

4. The method of claim 1, further comprising:

detecting addition or removal of a second module of the switch during operation of the switch; and

updating the status information based on information associated with the added or removed second module.

5. The method of claim 1, further comprising temporarily activating status indicators in response to active use of the status display panel, active use including navigation up or down the determined hierarchy using one or more navigation buttons.

6. The method of claim 5, wherein active use corresponds to one or more of the group consisting of activation of a line card user interface element, activation of a RPM user interface element, and activation of a switching fabric module (SFM) user interface element.

7. The method of claim 1, wherein the status information further includes power requirements, temperature limits, and cooling requirements.

8. The method of claim 1, further comprising applying a security policy to prevent undesirable configuration of the switch.

9. A non-transitory machine-readable medium comprising a plurality of machine-readable instructions which, when executed by one or more processors associated with a first module of a switch, are adapted to cause the one or more processors to perform a method comprising:

exchanging one or more messages with one or more detected modules of the switch to determine status information associated with each of the one or more detected modules, and a type of each of the one or more detected modules, wherein the first module is selected from a group of modules consisting of a switching module, a route processing module (RPM), and a cooling module, wherein the first module is interchangeably installable in one or more slots of the switch;

determining a hierarchy among the one or more detected modules of the switch based on the determined type of each of the modules of the switch;

organizing the status information associated with each of the one or more detected modules of the switch consistent with the determined hierarchy;

displaying the organized status information on a status display panel mounted on the first module of the switch on a plurality of status display screens, each of the status display screens displaying information at a corresponding level of the hierarchy and having one or more user interface elements for navigating between a current status display screen at a first level of the hierarchy to one or more of the status display screens at other levels of the hierarchy; and

managing, by an operator, the switch using the organized status information displayed on the status display panel.

10. The non-transitory machine-readable medium of claim 9, the method further comprising detecting a fault in one of the one or more detected modules of the switch, the fault selected from a group consisting of insufficient cooling, insufficient power, loss of communication, and switch failure.

11. The non-transitory machine-readable medium of claim 10, the method further comprising detecting insufficient cooling in response to installation of a new module in the switch.

12. The non-transitory machine-readable medium of claim 9, wherein the status information further includes power requirements, temperature limits, and cooling requirements.

13. A switching device, comprising:

a first module, wherein the first module is selected from a group of modules consisting of a switching module, a route processing module (RPM), and a cooling module; and

one or more second modules;

wherein the first module is configured to;

detect whether each of the one or more second modules are installed;

exchange one or more messages with the one or more second modules to determine status information associated with the one or more second modules, and a type of each of the one or more detected modules;

determine a hierarchy among the one or more second modules of the switching device based on the determined type of each of the modules of the switching device;

organize the status information associated with each of the one or more second modules of the switching device consistent with the determined hierarchy; and

display the organized status information on a status display panel mounted on the first module of the switching device on a plurality of status display screens, each of the status display screens displaying information at a corresponding level of the hierarchy and having one or more user interface elements for navigating between a current status display screen at a first level of the hierarchy to one or more of the status display screens at other levels of the hierarchy; and

wherein the organized status information displayed on the status display panel is usable by an operator to manage the switching device.

14. The switching device of claim 13, wherein the first module is further configured to detect a fault in one of the one or more second modules of the switching device, the fault selected from a group consisting of insufficient cooling, insufficient power, loss of communication, and switch failure.

15. The switching device of claim 14, wherein insufficient cooling is detected in response to installation of a new module in the switching device.
