The present disclosure relates to a network switch, more particularly, the disclosure relates to systems and methods for communicating with a network switch.
A network switch is a data link layer networking device that, for example, connects multiple network segments in a majority of Ethernet local area networks or LANS. Typically, when a new switch is added into such a network, a network administrator configures the network switch on a work bench before electrically connecting the switch to the network. The network switch is typically placed on a switch rack along with other network switches. If the switch has technical problems, the network administrator has to physically find the problematic network switch, connect the problematic network switch to a network administrator computing device via a wire, and fix the problematic switch using the network administrator computing device.
Systems and methods for communicating with a network device are provided. In this regard, a representative system, among others, includes a network switch associated with a telecommunications device; and a wireless interface device that wirelessly communicates with the network switch, the wireless interface device being configured to obtain information associated with the network switch and display at least a portion of the information obtained on a display device.
A representative method, among others, for communicating with a network switch includes establishing a wireless link between the network switch and a wireless interface device; obtaining information associated with the network switch by the wireless interface device via the wireless link; and displaying at least a portion of the information obtained on a display device of the wireless interface device.
Many aspects of the disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Exemplary systems are first discussed with reference to the figures. Although these systems are described in detail, they are provided for purposes of illustration only and various modifications are feasible. After the exemplary systems are described, examples of flow diagrams of the systems are provided to explain the manner in which a wireless interface device communicates with a network switch.
Alternatively or additionally, the switch racks 135, 145, 155 include radio frequency identification (RFID) readers/writers 137, 147, 157, respectively, which are configured to program location information associated with the physical location of the network switches on the switch racks 135, 145, 155. The location information includes the information associated with a specific row and column that the network switch is placed on the switch rack, the location of the switch racks 135, 145, 155 in switch rooms 130, 133, the location of the switch rooms 130, 133 in a building (not shown), and the location of the building, among others.
Alternatively or additionally, the network switch 140, 150, 160 can include flash memory that contains the location information associated with the network switch 140, 150, 160. Other information can be stored in the flash memory such as the type of network switch and information associated with the type of service provided by the network switch 140, 150, 160. Any information stored in the flash memory can be transmitted to the wireless interface device 105.
The one or more I/O devices 206 comprise components used to facilitate connection of the network switch 140, 150, 160 to other devices and therefore, for instance, comprise one or more serial, parallel, small system interface (SCSI), universal serial bus (USB), or IEEE 1394 (e.g., Firewire™) connection elements. The networking devices 208 comprise the various components used to transmit and/or receive data over a telecommunication network (not shown), where provided. By way of example, the networking devices 208 include a device that can communicate both inputs and outputs, for instance, a modulator/demodulator (e.g., modem), a radio frequency (RF) device 228 or infrared (IR) transceiver, etc. The RF device 228 includes, but is not limited to, a transceiver, Bluetooth™ and 802.11 a/b/n devices, among others.
The memory 202 can include any one or a combination of volatile memory elements (e.g., random access memory (RAM, such as DRAM, SRAM, etc.)) and nonvolatile memory elements (e.g., ROM, hard drive, tape, CDROM, etc.). The memory 202 normally comprises various programs (in software and/or firmware) including an operating system (O/S) 212, network switching logic 223, and location data 224, among others. The O/S 212 controls the execution of programs, including the network switching logic 223, and provides scheduling, input-output control, file and data management, memory management, and communication control and related services. The network switching logic 223 facilitates connecting multiple network segments in the telecommunication network.
The architecture for the wireless interface device 105 is similar to the architecture of the network switch 140, 150, 160 described above and therefore includes a processing device 229, memory 231, one or more I/O devices 241, and one or more networking devices 242, each of which is connected to a local interface 237. The networking devices 242 include, but are not limited to, a RF device 243 that facilitates communicating wirelessly with the network switch 140, 150, 160. The RF device 243 includes, but is not limited to, a transceiver, Bluetooth™ and 802.11 a/b/n devices, among others.
The wireless interface device 105 further includes, however, one or more user interface devices 239, which comprise those components with which the user (e.g., network administrator) can interact with the wireless interface device 105. Where the network switch 140, 150, 160 comprises a laptop computer, portable computer or similar devices, these components can comprise those typically used in conjunction with a computer such as a display device, keyboard and mouse.
The memory 231 of the wireless interface device 105, however, includes security access logic 232, locate logic 234, configure logic 235 and trouble shoot logic 236 that facilitates accessing, physically locating, configuring, and trouble shooting the network switch 140, 150, 160, respectively. Operation of the security access logic 232, locate logic 234, configure logic 235 and trouble shoot logic 236 are described in relation to
The wireless interface device 105 begins a process of handshaking with the network switch 140, 150, 160. The “handshaking” is generally referred to as an automated process of negotiation that dynamically sets the parameters of a communications channel established between the network switch 140, 150, 160 and the wireless interface device 105 before normal communication over the channel begins. The handshaking process facilitates establishing a wireless link between the network switch 140, 150, 160 and the wireless interface device 105.
In step 310, a security access logic 232 (
The MAC filtering is generally referred to as a security access control methodology whereby an address is assigned to each network switch 140, 150, 160 to determine access to the network switch. The MAC address is uniquely assigned to each network switch 140, 150, 160, and MAC filtering controls network access to specific network switches through the use of blacklists and whitelists.
If the authentication process is successful, step 320 accesses the network switch 140, 150, 160 to obtain information associated with the network switch and the wireless interface device 105 can, for example, locate, trouble shoot and configure the network switch 140, 150, 160. If the authentication process is unsuccessful at step 310, step 315 denies access to the network switch 140, 150, 160 and begins the authentication process with a second network switch 140, 150, 160 at step 325, which is similar to step 310. It should be noted that after the step 320 is completed, the wireless interface device 105 can begin the authentication process at step 325 with the second network switch 140, 150, 160. If the authentication process is unsuccessful at step 325, step 330 denies access to the second network switch 140, 150, 160 and begins the authentication process with a third network switch 140, 150, 160 (not shown).
Alternatively or additionally, the wireless interface device 105 can display a list of network switches 140, 150, 160 that are detected by the wireless interface device 105 during the handshaking process. A user can select at least one network switch from the list and then authenticate, access, trouble shoot, and configure the selected network switch.
Step 410 determines whether the wireless interface device 105 has security access to the network switch 140, 150, 160 by using an authentication process. In one embodiment, the authentication process includes, but is not limited to, at least one of a wireless encryption protocol (WEP), wi-fi protected access (WPA) and a medium access control (MAC) address filtering. At step 415, if the security access is denied, a security access logic 232 denies the wireless interface device 105 from accessing the network switch 140, 150, 160. At step 420, if the security access is successful, the wireless interface device 105 generally obtains information associated with the network switch 140, 150, 160.
In one embodiment, the wireless interface device 105 receives the location information associated with the network switch. Alternatively or additionally, the wireless interface device 105 can further receive fault-related information that describes the faulty condition of the network switch. The wireless interface device 105 displays the location information and/or fault-related information via a display device 239 of the wireless interface device 105. Alternatively or additionally, as shown in step 430, the wireless interface device 105 configures and troubleshoots the network switch 140, 150, 160 using the wireless interface device 105, which includes a network management software that facilitates the wireless interface device 105 to configure and troubleshoot the network switch 140, 150, 160.
