A communication apparatus comprises a CAM, an action determination unit, and a CAM diagnosis unit. The CAM includes, a plurality of entries each storing therein at least a portion of header information of frame, and a search circuit for each entry configured to determine whether or not a search key matches data stored at the entry. The search key is correlated with information indicating whether or not an entry matching the search key and an expected value of a search result including identification information of an entry matching the search key. The CAM diagnosis unit causes the CAM to search for an entry matching the search key. The CAM diagnosis unit diagnoses a failure occurring at the search circuit of an entry to be the test object when the result of the search does not match the expected value of a search result correlated to the search key.

Communication apparatus, and CAM failure diagnosis method

A display apparatus including: a collecting unit that collects power consumption information, wherein the power consumption information shows power consumption of a connecting device, and the connecting device interconnects a plurality of communication paths in a computer network; and a display unit that displays power consumption of the computer network, based on the power consumption information and constituent units based on a virtual network which is configured virtually on the computer network.

Assessing conditions of power consumption in computer network

A network system forms a computer network, and includes: a collecting unit; a calculating unit; and a display unit. The collecting unit collects power consumption information from a connecting device. The power consumption information shows power consumption of the connecting device. The calculating unit calculates power consumption of the computer network based on the collected power consumption information. The calculated power consumption is itemized into constituent units based on a configuration of the computer network. The display unit displays the calculated power consumption.
