Note: For the pimm command set, you can use the mnemonics int and ext instead of
the words internal and external.
Use pimm to determine the PIMM clock source (internal or external) and the clock mode
(synchronous or asynchronous). Example 3-53 shows sample output.
Example 3-53 pimm Command Output
001c07-L1>pimm
PIMM clock source is external
PIMM mode is asynchronous
Use pimm clksrc <external|internal> to set the PIMM clock source to external
or internal. Example 3-54 shows sample output.
Example 3-54 pimm clksrc internal Command Output
001c07-L1>pimm clksrc internal
nvram parameter changed, reset required to affect change.
Use pimm clkmode <async|sync> to set the PIMM clock mode to asynchronous (async)
or synchronous (sync). Example 3-55 shows sample output.
Example 3-55 pimm clkmode sync Command Output
001c07-L1>pimm clkmode sync
nvram parameter changed, reset required to affect change.
Used on C-bricks.
port
Use the port command to view the value of the status register for each port on a brick.
As shown in Example 3-56 and Example 3-57, the output of the port command contains
six columns, as follows:
• The Port column lists the name of each port.
• The Stat column lists the hexadecimal value of the status register for each port.
• The Remote Pwr column lists the value, “okay” or “none,” of the remote power OK
bit (bit 0) for each port.
