Abstract
An apparatus includes a network port and a switch management processor. The network port receives packets over a network, where the packets include a management packet and a trigger packet. The switch management processor executes a command in selected management packets received over the network when a trigger pattern generated based on the trigger packet matches a bit pattern stored in memory. The bit pattern is stored in the memory during a predetermined period after the management packet is received. The predetermined period is selected based on a desired security level.
Claims20
A network switch configured to communicate with network devices on a network, the network switch comprising:
- a central processing unit (CPU) port configured to communicate with a CPU associated with the network switch;
- a plurality of network ports configured to communicate with the network devices on the network, wherein at least one of the network devices comprises a network management unit for managing one or more of the network devices on the network;
- and
- a switch management processor configured to process, without burdening the CPU, selected instructions in management packets received from the network management unit via the network ports when a trigger pattern in a trigger packet corresponds to a bit pattern stored in memory during a predetermined period after one of the management packets is received, the predetermined period being selected based on a desired security level.

A network switch comprising:
- a plurality of ports configured to communicate with network devices on a network, wherein at least one of the network devices comprises a network management unit for managing one or more of the network devices on the network;
- and
- a switch management processor configured to
- receive a management packet from the network management unit via one of the ports, and
- process a selected instruction in the management packet in response to a trigger pattern in a trigger packet matching a bit pattern stored in memory during a predetermined period after the management packet is received, the predetermined period being selected based on a desired security level.
