supporting 8X link aggregation. NOTE: The option portName is case sensitive. To
force links to only operate at 8X, use the '8X only' option.
Calling this command without the enable8xBit option will display the current values
of the port(s).
Calling this function with the [-bounce] option disruptively brings active links down
and back up so the links use the new setting immediately. Otherwise the new setting
will be used the next time links retrain.
ismChassisSet12x
Allows the user to view, set and unset the chassis link width (including external ports).
Syntax:
ismChassisSet12x [enable8xBit] [-bounce]
Options:
enable8xBit
2=enable(8X only) 1=enable(AUTO 1X/4X/8X), 0=disable.
-bounce
Brings the active links down and back up if a new value is set.
Sample Output:
-> ismChassisSet12x
L01P01 8x mode is DISABLED
L01P02 8x mode is DISABLED
L01P03 8x mode is DISABLED
L01P04 8x mode is DISABLED
L01P05 8x mode is DISABLED
...
NOTES: This command included for backwards compatibility. The
ismChassisSetWidth command is prefered.
This command ONLY works on switches supporting 8X link aggregation. This
command will enable 8X link aggregation so that Internal AND External switching
will be at 8x. Each 8X port is 2 aggregated 4x ports (i.e., a DUO), where one will
be reported as an 8x port, and the other port is reported as disabled. Each of the
two aggregated 4x ports must be connected to another enabled 8X Duo to establish
a 8X link. To force links to only operate at 8X, use the '8X only' option. Calling this
command without the enable8xBit will display the ports' current values.
Calling this function with the [-bounce] option disruptively brings active links down
and back up so the links use the new setting immediately. Otherwise the new setting
will be used the next time links retrain.
