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)
