LACP ports listed under the “show lacp issu-impact” as not ISSU ready
Applies to
- Cisco Nexus modular switches with dual supervisors (e.g. Nexus 7000)
- Switch upgrade with In-service software updates (ISSU)
- NetApp Element software
- NetApp SF-Series
- NetApp H-Series
Issue
- On Cisco modular switches with dual supervisors in-service software updates (ISSU) are supported. LACP ports listed under the command
show lacp issu-impact
report asnot ISSU ready
- The Nexus upgrade process will therefore force the chassis itself to upgrade disruptively if LACP fast is used. A “disruptive” upgrade means the chassis itself will fully reload which in essence would impact all ports on the switch and not just the “LACP fast” ones.
- Recommendation from Cisco is not to change to LACP fast on Nexus modular switches
