Frame transmission equipment and the normality check method

Title:

Frame transmission equipment and the normality check method

Document Type and Number:

Japanese Patent JP6166960

Kind Code:

B2

Abstract:

A frame transmission apparatus includes multiple ports provided in a line unit, and a setting control unit. The setting control unit checks the normality of the frame transfer state within the apparatus by transferring a maintenance management frame from a first port to a second port within the apparatus. When the first port is a logical port configured by link aggregation of multiple physical ports, the setting control unit selects each of the multiple physical ports as a transmission source port and transfers multiple maintenance management frames from the multiple physical ports to the second port.
