摘要： PROBLEM TO BE SOLVED: To provide a negotiation failure detection system for improving efficiency in network operation monitoring in consideration of the occurrence of a failure in a network apparatus and a cable or the like by automatically detecting a negotiation failure of a communication adaptor such as an Ethernet (R) and to provide a network monitoring apparatus.
SOLUTION: The negotiation failure detection system includes: a means for cyclicly (cyclically) collecting the MIB (Management Information Base) specified by the RFC 1213 in collecting interface system information by the network monitoring apparatus; a means of storing the interface system information in time series so that transition of error counts can be obtained for each Ethernet interface; and a means for informing a network administrator about negotiation conflict by monitoring Input errors and Output errors counted in time series on the basis of the statistic information (only the standard MIB) of the Ethernet (R) interfaces.

摘要： PROBLEM TO BE SOLVED: To enable a network terminal which performs communication using a tagged frame like IP-Phone to automatically set a VLAN according to a network to which the network terminal is connected. SOLUTION: A plurality of VLAN-IDs are registered in a terminal beforehand and when the terminal is connected to a network. a connection request is made to the network while tagging the registered VLAN-IDs in order. When a right connection request comes from the terminal, at a network side, the request is answered. A function for the connection request and answer utilizes a DHCP function. When a VLAN-ID set at the network side is coincident with a VLAN-ID with which the terminal establishes connection, it is notified the terminal from the network side that the terminal has been connected to the network using the right VLAN-ID. Upon receipt of the notification, the terminal determines that the VLAN-ID with which the connection has been established is right and performs VLAN setting using the VLAN-ID.

摘要： PROBLEM TO BE SOLVED: To provide a method of measuring a network response time and a network transport factor so as to locate a degradation causing spot in a network system failure analysis support method.
SOLUTION: In a network of connecting a plurality of clients and a plurality of servers, a response time and/or a transport factor in a path from a branch line to a counter branch line is measured, a spot which causes degradation in the response time/transport factor is automatically obtained by the comparison of a plurality of pieces of path information, operation information is collected from a network instrument located at the degradation causing spot, it is determined on the basis of the operation information whether degradation in the response time/transport factor is induced by a lack of the performance of the network instrument or a line bandwidth, the interface of the network instrument on a degraded path is blocked, and communication is detoured to another path where no degradation is detected.
