Abstract

An apparatus to manage a set of switches in a computer network is described. In particular, a computer-readable medium to direct a computer network to function in a specified manner is provided. The computer-readable medium comprises instructions to configure a first switch of a set of switches as a first master switch and instructions to identify a first plurality of switches of the set of switches that are connected to the first master switch. The first plurality of switches includes a second switch and a third switch, and the second switch can be configured as a second master switch. The computer-readable medium also comprises instructions to modify an operational parameter associated with the third switch using the first master switch.

Claims

1. A non-transitory computer-readable storage medium storing computer instructions to function in a specified manner, said computer instructions comprising:

instructions to configure a first switch of a set of switches as a first master switch;

wherein said instructions to configure said first switch include;

instructions to display an user-interface indicating a plurality of switch states associated with said first switch, said plurality of switch states including a master switch state associated with said first switch and a slave state associated with said first switch; and

instructions to receive, via said user-interface, a user-specified selection of said master switch state associated with said first switch to configure said first switch as said first master switch;

instructions to identify a first plurality of switches of said set of switches that are connected to said first master switch, said first plurality of switches including a second switch and a third switch,

instructions to modify a first operational parameter associated with said third switch using said first master switch, such that said third switch performs switching operations in accordance with said modified first operational parameter;

instructions to configure, using said first master switch, said second switch being configured as a second master switch while said first switch remains configured as said first master switch, wherein said instructions to configure said second switch include;

instructions to identify said second switch as being in a slave switch state associated with said second switch; and

instructions to configure, using said first master switch, said slave switch state associated with said second switch to a master switch state associated with said second switch;

instructions to identify a second plurality of switches of said set of switches that are connected to said second master switch, said second plurality of switches including said first switch and said third switch; and

instructions to modify a second operational parameter associated with said third switch using said second master switch, such that the third switch performs switching operations in accordance with said modified second operational parameter.

2. The non-transitory computer-readable storage medium of claim 1, wherein said instructions to identify said first plurality of switches of said set of switches that are connected to said first master switch include:

instructions to identify at least 16 switches of said set of switches that are connected to said first master switch.

3. The non-transitory computer-readable storage medium of claim 1, further comprising:

instructions to modify a third operational parameter associated with said second master switch using said first master switch.

4. The non-transitory computer-readable storage medium of claim 1, wherein said instructions to identify said first plurality of switches that are connected to said first master switch include:

instructions to direct said first master switch to transmit a polling signal to said third switch and to receive an acknowledgment signal, transmitted in response to said polling signal, from said third switch.

5. The non-transitory computer-readable storage medium of claim 4, wherein at least one of said polling signal and said acknowledgement signal is incorporated in an Ethernet frame.

6. The non-transitory computer-readable storage medium of claim 1, wherein said instructions to modify said first operational parameter associated with said third switch include:

instructions to direct said first master switch to transmit, in response to an user-specified selection of said third switch, an access request signal to said third switch and to receive an access response signal, transmitted in response to said access request signal, from said third switch.

7. The non-transitory computer-readable storage medium of claim 6, wherein at least one of said access request signal and said access response signal is incorporated in an Ethernet frame.

8. The non-transitory computer-readable storage medium of claim 1, wherein said instructions to modify said first operational parameter associated with said third switch include:

instructions to direct said first master switch to transmit data associated with said first operational parameter to said third switch.

9. The non-transitory computer-readable storage medium of claim 8, wherein said data is incorporated in an Ethernet frame.

10. A method of managing a computer network, comprising:

providing a stack of Ethernet switches;

configuring a first Ethernet switch of said stack of Ethernet switches as a first master switch;

configuring, using said first master switch, a second Ethernet switch of said stack of Ethernet switches as a second master switch while said first Ethernet switch remains configured as said first master switch, wherein said configuring said second Ethernet switch includes;

displaying, in a user-interface screen associated with said first master switch, a switch state of said second Ethernet switch as corresponding to a slave switch state;

displaying, in said user-interface screen, an option corresponding to a master switch state; and

receiving user input to select said option to modify said switch state of said second Ethernet switch from said slave switch state to said master switch state;

receiving an user-specified selection of one of said first master switch and said second master switch; and

modifying an operational parameter associated with a third Ethernet switch of said stack of Ethernet switches using said selected one of said first master switch and said second master switch, wherein said operational parameter is associated with one or more switching operations performed by said third Ethernet switch.

11. The method of claim 10, further comprising:

identifying a plurality of Ethernet switches of said stack of Ethernet switches that are connected to said selected one of said first master switch and said second master switch, said plurality of Ethernet switches including said third Ethernet switch.

12. The method of claim 10, wherein modifying said operational parameter associated with said third Ethernet switch includes:

transmitting data associated with said operational parameter between said third Ethernet switch and said selected one of said first master switch and said second master switch, said data being incorporated in an Ethernet frame.

13. The method of claim 10, further comprising:

configuring said third Ethernet switch as a slave switch.

14. The method of claim 10, further comprising:

connecting said first Ethernet switch, said second Ethernet switch, and said third Ethernet switch using a cascade topology.

15. The method of claim 10, wherein said operational parameter corresponds to one of an operating speed of a port included in said third Ethernet switch, a duplex mode of said port, an auto-negotiation status setting of said port, a flow control setting of said port, and a security setting of said port.

16. The method of claim 10, wherein said operational parameter corresponds to a Virtual Local Area Network configuration parameter.

17. The method of claim 10, wherein said operational parameter corresponds to a Spanning Tree Protocol configuration parameter.

18. The method of claim 10, wherein said operational parameter corresponds to an Internet Protocol configuration parameter.
