Cannot find flex link feature on C9500-48Y4C
Cisco IOS XE Software, Version 16.09.03
According to command reference, it has to be there
But in CLI there is no such option. What am I doing wrong?
Solved! Go to Solution.

Hello

Vladimir,
Flexlink+ is an Access Layer feature delivered in 16.12.1 that will not be on the core / aggregation platforms of 9500 High Performance and 9600. I have sent the documentation example to the product management team to get it updated as there is no Flexlink in any release prior to 16.12 .

So 16.12.1 + flexlink will be available correct?

Paul,
IOS XE 16.12.1 shipped last week, so Flexlink+ is here for Access Layer platforms. Please check the release notes for the platform in which you are interested, and note that there is no plan for Flexlink+ for 9500 High Performance and 9600.

Will FlexLinks be available on c9200 switches?
We need FlexLinks so we can redundantly connect our management switches behind FEX modules (without using spanning-tree).

UPDATE - We were able to successfully implement FlexLinks+ functionality on our c9200's with these instructions that use REP.
