Question

A storage administrator completes a nondisruptive ISSU on a Nexus 9000 switch to upgrade the NX-OS software. After the upgrade, a new NX-OS feature that depends on updated hardware programmable logic still fails to function correctly. The 'show install all impact epld' output indicates certain EPLD images differ from those currently running on the line cards. What is the correct conclusion the administrator should draw?

Accepted Answer

EPLD upgrades are a separate process from the NX-OS ISSU and may be required to enable new hardware-dependent functionality

Answer

EPLD images are bundled automatically with every ISSU, so the failure must be a software bug unrelated to hardware logic

Answer

The switch must be downgraded because EPLD mismatches always prevent NX-OS from booting the new image

Answer

EPLD images can only be updated by physically replacing the affected line cards
