    摘要: 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.
