Which statement about electronic programmable logic device image upgrades is true?

  • A. EPLD and ISSU image upgrades are nondisruptive.
  • B. An EPLD upgrade must be performed during an ISSU system or kickstart upgrade.
  • C. Whether the module being upgraded is online or offline, only the EPLD images that have different current and new versions are upgraded.
  • D. You can execute an upgrade or downgrade only from the active supervisor module.


Answer : D

Explanation:
You can upgrade (or downgrade) EPLDs using CLI commands on the Nexus 7000 Series device. Follow these guidelines when you upgrade or downgrade EPLDs:



You can execute an upgrade from the active supervisor module only. All the modules, including the active supervisor module, can be updated individually.


You can individually update each module whether it is online or offline as follows:


If you upgrade EPLD images on an online module, only the EPLD images with version numbers that differ from the new EPLD images are upgraded.

If you upgrade EPLD images on an offline module, all of the EPLD images are upgraded.


On a system that has two supervisor modules, upgrade the EPLDs for the standby supervisor and then switch the active supervisor to standby mode to upgrade its EPLDs.
On a system that has only one supervisor module, you can upgrade the active supervisor, but this will disrupt its operations during the upgrade.


If you interrupt an upgrade, you must upgrade the module that is being upgraded again.


The upgrade process disrupts traffic on the targeted module.

Do not insert or remove any modules while an EPLD upgrade is in progress.
