tnPortExcessiveCollisionMode
Module: TN-PORT-MIB
OID (symbolic): TN-PORT-MIB::tnPortExcessiveCollisionMode
OID (numeric): 1.3.6.1.4.1.868.2.5.141.1.1.1.6
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Configure port transmit collision behavior. Discard: Discard frame after 16 collisions (default). Restart: Restart backoff algorithm after 16 collisions.
What is tnPortExcessiveCollisionMode?
This read-write INTEGER, discard(1) or restart(2) and defaulting to discard, configures how the port's transmit logic behaves after hitting 16 collisions on a half-duplex link: either discard the frame or restart the backoff algorithm and keep trying. An admin changes this from the default discard(1) to restart(2) on a legacy half-duplex segment where dropping frames after repeated collisions is less acceptable than retrying. Setting tnPortExcessiveCollisionMode to restart(2) on a noisy half-duplex hub connection keeps the port retrying frames instead of giving up after 16 collisions.
