collisionBackoff - configure the collision backoff parameters for 10/100 ports
SYNOPSIS
collisionBackoff sub-command options
DESCRIPTION
The collisionBackoff command is used to configure the parameters for collision backoff operations for 10/100 ports.
STANDARD OPTIONS
collisionConstant
Each successive retry operates by selecting a time slot over a range that doubles with each retry (2, 4, 8, ... 1024). This value controls the maximum number of time slots used. The values are powers of 2 from 0 through 1024. (default = 10)
continuousRetransmit true / false
If set, when a collision occurs, continuously retransmit the packet until the maxRetryCount is exhausted. (default = false)
maxRetryCount
The maximum number of retries for each packet. (default = 16)
random true / false
If set, when a collision occurs, wait a random amount of time before retrying the transmission. The maxRetryCount and collisionConstant values govern how often and long retries is attempted. (default = true)
