5.9.14 link-signal-tune
Function
This command performs the settings for the internal parameter used for Rx signal optimization and for the timing at which
optimization will be performed.
Use the no form to return to the default setup.
When connecting with an IEEE802.3ak compliant device it is not necessary to change settings using this
command.
Prompt
xg(config)#
Command syntax
link-signal-tune [adjustment { auto | short | long }] [mode { auto | hold }] port <1-12>
[<1-12> ]no link-signal-tune port <1-12> [<1-12> ]
Parameter
[adjustment { auto | short | long }
Specifies the internal parameter used for Rx signal optimization.
−
auto
Selects the internal parameter based on the Rx signal from the partner device.
−
short
Selects the appropriate internal parameter for the comparatively strong Rx signal when the 10GBASE-CX4
connection cable is short etc.
−
long
Selects the appropriate internal parameter for the comparatively weak Rx signal when the 10GBASE-CX4
connection cable is long etc.
When this parameter is omitted, "auto" is specified.
[mode { auto | hold }
Sets the timing at which Rx signal optimization is performed.
−
auto
Automatically optimizes the Rx signal every time a new signal is detected from the partner device.
−
hold
Retains the optimized state of a Rx signal that was firstly optimized when detected. After the first optimization,
optimization is not performed again.
When this parameter is omitted, "auto" is specified.
port <1-12> [<1-12> ]
Specifies the switch port number to change its setting. When specifying multiple port numbers, list them separated with
" " (space).
Command type
Configuration command
Default
adjustment: auto
mode : auto
Notes
When the "bridge jumbo-frame" command is executed, even if the mode is "hold", optimization is performed again.
About 15 seconds is required for optimization. After optimization link up is performed.
Example
In the following example, for port number 1, the internal parameter is automatically selected based on the Rx signal and it is set
to the mode that performs optimization for the Rx signal automatically.
xg(config)# link-signal-tune adjustment auto mode auto port 1
