Description: The software rev number (major.minor).
What is cardSwRev?
This reports the running firmware or software revision loaded on this specific card, in major.minor form. Because different cards in the same chassis can end up on different firmware revisions after a rolling or partial upgrade, an admin checks this per-card rather than assuming chassis-wide consistency, especially before troubleshooting a bug that's version-specific. For example, discovering cardSwRev reads 4.2 on one IOP card while its redundant partner shows 4.3 explains a subtle behavioral mismatch between the two after an incomplete upgrade.
Examples
