Frame transmission apparatus and method for checking normality

摘要

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.

1. A frame transmission apparatus, comprising:
a first port; a second port; and a controller configured to check connectivity between the first port and the second port by transferring a predetermined maintenance management frame from the first port to the second port, wherein, when the first port is a logical port configured by logically bundling a plurality of physical ports by link aggregation, the controller selects each of the plurality of physical ports as a transmission source port and transfers a plurality of maintenance management frames from the plurality of physical ports to the second port.
