Graphing switch port data 51Field DescriptionLateCollisions The number of times that a collision is detected ona particular interface later than 512 bit-times intothe transmission of a packet. Five hundred andtwelve bit-times corresponds to 51.2 microsecondson a 10 Mb/s system. A (late) collision included ina count represented by an instance of this objectis also considered as a (generic) collision forpurposes of other collision-related statistics.ExcessiveCollisions A count of frames for which transmission on aparticular interface fails due to excessive collisions.—End—Bridge tabThe Bridge tab displays read-only information about port frame statistics.To view the Bridge tab, follow this procedure:Step Action1 Open the Graph Port screen by selecting one or multiple ports onthe Device View and then selecting Graph > Port from the menu.The Graph Port screen will open.2 Select the Bridge tab.
