# Ethernet Collisions

From this dialog box, you can monitor the Ethernet collisions that have taken place on an interface.

## Navigation

Right-click the port and then select Monitor > Ethernet Collisions.

### Single Collision Frames (dot3StatsSingleCollisionFrames)

Pattern of occurrences and number of successfully transmitted frames for which there was exactly one collision.

### Multiple Collision Frames (dot3StatsMultipleCollisionFrames)

Pattern of occurrences and number of successfully transmitted frames for which there were multiple collisions.

### Late Collisions (dot3StatsLateCollisions)

Number of times that a collision was detected later than 64 octets into the transmission. (The total number of late collisions is added into the collision count.) Late collisions indicate either that the network has too large a propagation delay between the reporting station and some other stations, or that some other station is not detecting/responding to collisions correctly.

### Excessive Collisions (dot3StatsExcessiveCollisions)

Pattern of occurrences and latest number of frames for which transmission failed because of excessive collisions.
