upstream <port number> ranging 611
upstream <port number> ranging
Configures ranging on the specified upstream port. This allows you to tune how cable modems
adjust power levels during the ranging process.
Mode
interface:cable:csi(<c/s/i>)
Syntax
upstream <port number> ranging {init-range-timeout <number> |
max-power-adjust <number> | power-offset-threshold <number> |
zero-frequency-adjust {disable|enable} | zero-power-adjust
{disable|enable}| zero-timing-adjust {disable|enable}}
Arguments
<port number> Number of the upstream port for which you want to configure
ranging parameters.
init-range-timeout
<number>
This is the minimum time allowed for a cable modem following
receipt of a RNG-RSP, before it is expected to reply to an
invitation to range request in milliseconds. By default, the cm
range invite timeout is set at 400 milliseconds.
max-power-adjust
<number>
The maximum adjustment permitted on a single Range Response
message. By default, maximum power adjustment is set at 6 dB.
power-offset-threshold
<number>
If power level offset reported by MAC chip is less than or equal to
this threshold value, then power level adjustment may be
stopped. By default, power offset threshold is set at 8. Values
range from 0 to 4294967295.
zero-frequency-adjust
{disable | enable}
If enabled, the frequency adjustment item in range response
message is unconditionally set to 0. Useful for debugging. By
default, zero frequency adjustment is disabled.
zero-power-adjust
{disable | enable}
If enabled, the power adjustment field in the range response
message is unconditionally set to 0. Useful for debugging. By
default, zero power adjustment is disabled.
zero-timing-adjust
{disable | enable}
If enabled, the timing adjustment item in range response
message is unconditionally set to 0. Useful for debugging. By
default, timing adjustment is disabled.
