ISSU in Nexus 9k

[RijeeshW]

Hello,

We are planning to introduce nexus N9K-C9508-B3-E switches in our environment and we were using catalyst all these years. We used to do ISSU for software upgrade with near to zero downtime.

Would like to know in nexus 9k also we have option of ISSU without any service interruption.

Also how does it differ from GRI

Thanks

Hi there,

ISSU is certainly possible on some Nexus 9000s assuming all requirements (SW/HW) are met. Here's a good starting point:

Hope that helps!
