Switching

I must be missing the command, but I've searched and cannot find anything related.

We have a EX9214 with a EX9200-6QS line card (combo 24x10 and 6x40) card.

The 10Gb pics (0 and 1) are online but the 40 Gb pics(2 and 3) are not . This is based on the output of the "show chassis pic" command. 

Thanks!

This card is either 24 x 10 or 6 x 40, not both.  I believe you can also a combination of 3 x 40 and 12 x 10.  240G max.  The 6 x 40 are Pic 2 and Pic 3, or 2/0-2/2 and 3/0-3/2.  Disable the 0/0-0/11 and 1/0-1/11 and then enable 2 and 3 and your 40G ports should then come alive.  See bottom of this URL:

I found the solution/information with JTAC's help:

From the ticket...

Due to the HW limitations (thermal and cooling constraints), it can support only a maximum of 2 PICs at a time.  Hence, a CLI knob was designed to offline the PICs which will help the users to select the PICs needed.  Since this is a fixed port MPCs, at least one PIC wasexpected to be online for this MPC.  Otherwise, there is no WAN interfaces for this MPC.  Hence, the CLI knob was intentionally designed to have at least one PIC to be online.  If all the PICs are offline in the CLI, it will be treated as an invalid configuration.

The PICs 0 and 2 belong to PFE-0 and the PICs 1 and 3 belong to PFE-1.  In other words, the even numbered PICs belong to the even number PFE (i.e. PFE-0) and the odd numbered PICs belong to the odd number PFE (i.e. PFE-1).

If there is a CLI configuration with an invalid PIC combination, the default PICs (PIC-0 and PIC-1) will be powered ON.  Also, a syslog message will be displayed to indicate the invalid PIC combination selected.

There won't be any CLI commit failures when an invalid PIC combination is selected.  In other words, the commit will succeed even for the invalid PIC combination.

Here is the table which summarizes the various possible combinations and the expected behavior.

CLI Configuration

PIC Selection

Default (i.e. no CLI configuration)

Online: PIC-0, PIC-1

Offline: PIC-2, PIC-3

PIC-1, PIC-2 and  PIC-3 powered OFF

Online: PIC-0

Offline: PIC-1, PIC-2, PIC-3

PIC-0, PIC-2 and PIC-3 powered OFF

Online: PIC-1

Offline: PIC-0, PIC-2, PIC-3

PIC-0, PIC-1 and PIC-3 powered OFF

Online: PIC-2

Offline: PIC-0, PIC-1, PIC-3

PIC-0, PIC-1 and PIC-2 powered OFF

Online: PIC-3

Offline: PIC-0, PIC-1, PIC-2

PIC-2 and PIC-3 powered OFF

Online: PIC-0, PIC-1

Offline: PIC-2, PIC-3

PIC-1 and PIC-2 powered OFF

Online: PIC-0, PIC-3

Offline: PIC-1, PIC-2

PIC-0 and PIC-3 powered OFF

Online: PIC-2, PIC-1

Offline: PIC-0, PIC-3

PIC-0 and PIC-1 powered OFF

Online: PIC-2, PIC-3

Offline: PIC-0, PIC-1

The commands to disable pic's are (replace X with your desired values):

 set chassis fpc X pic X power off

 set chassis fpc X pic X power off

You can confirm status of the PIC before and after using this command (where X is your fpc):

show chassis fpc pic-status X

Example output:

before...

admin@9214> show chassis fpc pic-status 7

Slot 7 Online EX9200 24x10GE+6x40GE
PIC 0 Online 12X10GE SFPP
PIC 1 Online 12X10GE SFPP
PIC 2 Offline 3X40GE QSFPP
PIC 3 Offline 3X40GE QSFPP

after...

admin@9214> show chassis fpc pic-status 7
Slot 7 Online EX9200 24x10GE+6x40GE
PIC 0 Online 12X10GE SFPP
PIC 1 Offline 12X10GE SFPP
PIC 2 Offline 3X40GE QSFPP
PIC 3 Online 3X40GE QSFPP

The error message I was getting in log messages while trying to bring 2 pic's from the same PFE online:

Apr 27 10:15:03 9214-re0 chassisd[2023]: fpc_pic_process_pic_power_off_config :Invalid pic combination configured on FPC 7 Using default Pics 0 and 1

This card is similar to the MX linecard MPC5E-40G10G and I found these articles of use:

Hopefully this saves someone else a support call/ticket...
