Example 3-25 ioport Command Output for a C-Brick
001c07-L1>ioport
Junkbus I/O port speed: 600 MHz - current, attached I/O is detected
400 MHz - default, when no attached I/O
detected
Example 3-26 ioport Command Output for an X-Brick
001i21-L1>ioport
XBridge port A speed: 400 MHz - current, no attached C detected
XBridge port B speed: 600 MHz - current, from attached C
400 MHz - default, when no attached C detected
XBridge UST clock source: port A
Use ioport 400|600 to set the speed of the I/O ports. You can set the I-, P-, PE-, X-, or
V-bricks to 400 or 600 (400 MHz or 600 MHz). Example 3-27 shows sample output from
the ioport 600 command.
Example 3-27 ioport 600 Command Output
001x004-L1>ioport 600
nvram parameter changed, reset required to affect change.
Use the other commands in this set as follows:
• Use ioport a 400|600 to set the I/O port A to either 400 MHz or 600 MHz.
• Use ioport b 400|600 to set the I/O port B to either 400 MHz or 600 MHz.
• Use ioport clksrc a|b to set the universal system time (UST) clock source in
the I-, P-, PE-, X-, or V-brick to port A or port B. The options are A or B.
Example 3-28 shows sample output from the ioport clksrc a command. These
commands are valid only for the I-, P-, PE-, X-, and V-bricks.
Example 3-28 ioport clksrc a Command Output
001x004-L1>ioport clksrc a
nvram parameter changed, reset required to affect change.
Used only on C-, I-, P-, PE-, X-, and V-bricks.
