摘要： A method for distributing addressed data packets from an input channel to a multiplicity of packet queues includes receiving said addressed data packets and, responsive to first hashed addresses, distributing the addressed data packets to said queues in accordance with said first hashed addresses. A first hash function is applied to selected address data of each of said addressed data packets to produce said first hashed addresses. At the same time a succession of different hash functions is applied to said selected address data in each of the packets to produce second hashed addresses and occurrences of each of the second hashed addresses are counted so as to obtain for each of said different hash functions a respective one of a plurality of set of counts, each such set representing the distribution of said packets that would occur in said queues if the respective one of the different hash functions had been applied to said addressed data packets. The sets of counts are analyzed to determined which one of them represents a best distribution of said packets and the hash function associated with the best distribution is applied to incoming packets in place of the said first hash function.

摘要： Port mirroring is achieved between ports on separate devices in a stack of communication devices by establishing a protocol for communications within a cascade connection forming the stack in which an indication is given of whether the communication is being sent to the mirror port in addition to its intended destination. This avoids increasing the volume of traffic in the cascade connection as would be the case if the original and mirror copy were sent separately.
摘要翻译：在通信设备的堆叠中的单独设备上的端口之间实现端口镜像，通过建立用于形成堆栈的级联连接中的通信协议，其中给出除了其预期之外是否将通信发送到镜像端口的指示目的地。这样可以避免增加级联连接中的流量，就像分开发送原始和镜像副本的情况一样。

摘要： Trunking or other relationship is defined between ports on different devices in a cascade connected stack of network devices. When network communications are passed via the cascade connection an indication is included of whether it originated from a port which is part of a trunk and thereby port-mismatch errors can be avoided.
摘要翻译：在串联连接的网络设备堆栈中的不同设备上的端口之间定义了中继或其他关系。当通过级联连接通过网络通信时，包括是否源自作为中继线一部分的端口的指示，从而可以避免端口不匹配错误。
