Description

(PTX devices with PTX10K-LC1301-36DD Line Card Only) Chassis PFE interoperability configuration. PTX10008 supports line cards based on express4 ASIC (LC1201, LC1202) and express5 ASIC (LC1301). By default, all line cards on the PTX device are active and interoperate. Certain features can be enabled in the system only if all active line cards are express5 ASIC-based. This command brings up the PTX10K-LC1301-36DD line cards to support the express5 ASIC capabilities only on a supported PTX device. All other line cards remain offline in this mode due to incompatibility. You can verify the current interoperability mode on your device using the show chassis interoperability command.

Note:

Due to its system wide implications, any change in the interoperability configuration requires a reboot of the system including all REs, FPCs, and SIBs using the request system reboot command. Until the system is rebooted, you must ensure that:

  • The individual REs are not rebooted. Rebooting individual REs alone is not sufficient for proper system operation.

  • In case of any uncontrolled event resulting in an RE reboot, the full system must be restarted immediately to prevent inconsistent system state.

With the interoperability configuration present and after system reboot, at any point in system operation, if a new RE is plugged into the backup RE slot and brought online, the backup RE may need an additional reboot to ensure it comes up in a consistent state. Please note that by default GRES is enabled in a dual RE system.
Note:

Line cards with express4 ASICs, such as LC1201 and LC1202, do not come online in express5-enhanced mode. The message, FPC incompatible with interop config, indicates this when you run the show chassis fpc command. Even a CLI request command cannot bring these cards online. Use the show chassis interoperability command to view the current interoperability mode.
