| 20080310432 | AUTONEGOTIATION OVER AN INTERFACE FOR WHICH NO AUTONEGOTIATION STANDARD EXISTS - A method for enabling autonegotiation over an interface for which no autonegotiation standard exists comprises establishing network communication between a first network device and a second network device over a communication link. The first network device includes a first media access controller (MAC) associated with a communication port coupled to the communication link and a second MAC positioned between the first MAC and the communication port, and the second MAC operates as a proxy MAC for the first MAC. The first MAC outputs an outbound data communication to the communication port at a first communication rate. The proxy MAC intercepts the outbound data communication. The proxy MAC then outputs the outbound data communication to the communication port at a second communication rate different from the first communication rate. | 12-18-2008 |
| 20100278076 | AUTOMATIC CONFIGURATION OF VIRTUAL NETWORK SWITCHES - In general, techniques are described in which a plurality of network switches automatically configure themselves to operate as a single virtual network switch. A virtual switch is a collection of individual switch devices that operate like as single network switch. As described herein, network switches in a network that are capable of participating in a virtual switch may automatically discover one another. The participating network switches may then elect one of the participating switches as a master switch. The master switch may generate forwarding information and store the forwarding information in the participating switches, including the master switch. The forwarding information causes the participating switches to act like a single network switch. | 11-04-2010 |
| 20110118889 | INCREASING MEAN TIME BETWEEN FAILURES FOR POWER SUPPLIES - A redundant power supply may obtain a rule for increasing mean time between failures (MTBF) for a first internal power supply and a second internal power supply connected to an electronic device, apply the rule to the first and second power supplies, activate the second internal power supply based on the rule to permit the second internal power supply to provide power to the electronic device, and deactivate the first internal power supply based on the rule. | 05-19-2011 |
| 20110149743 | Network distribution prevention when virtual chassis system undergoes splits and merges - A method performed by network devices that includes operating in a normal mode, where the network devices form a virtual chassis that corresponds to a single logical network device; detecting when a failure within the virtual chassis occurs; executing a splitting process to form one or more new virtual chassis in correspondence to the failure; determining whether one of the one or more new virtual chassis operates as a functioning virtual chassis based on whether at least one of a set of criteria is satisfied, where the functioning virtual chassis operates according to resources configured for the virtual chassis; and operating as a nonfunctioning virtual chassis when it is determined that the one of the one or more virtual chassis does not satisfy the at least one of the set of criteria, where the nonfunctioning virtual chassis operates in a pass-through mode. | 06-23-2011 |
| 20110161489 | AUTOMATIC AGGREGATION OF INTER-DEVICE PORTS/LINKS IN A VIRTUAL DEVICE - A virtual device includes multiple devices connected to operate as a single device. A first one of the devices is configured to determine that the first device connects to a second one of the devices via a first link; identify a second link; determine that the second link connects the first device to the second device; and automatically aggregate the first link and the second link to form a link aggregation with the second device based on determining that the first device connects to the second device via both the first and second links. The first device is further configured to transmit packets to the second device via the first and second links of the link aggregation. | 06-30-2011 |
