Catalyst 9500-40X - Stackwise Virtual soon?

[campbech1]

I'm looking to implement a couple 9500-40Xs with Network Advantage as core switches at two smaller locations. Any dates on when the 40Xs will support stackwise-virtual? I see, at least based on the release notes, that only the 24 port 40G model supports it currently.

Yes supposed to be March

I am wondering if its the fact its Easter delaying it of if they had a problem with the release. Its now 2nd April and not there. I have been waiting on its release all month.

I've had a pair of C9500-40X switches in a stackwise-virtual configuration for a few weeks now.  We're running 16.6.2b code.

Does it working properly?

[campbech1]

We are also running 16.6.2 with Stackwide-virtual on a pair of 9500-40Xs but the upgrade to 16.6.3 does NOT have stackwise-virtual commands available, at least not for the 9500-40Xs. 

[roland.sonder]

Stackwise virtual support for 9500-40X requires at least 16.8.1a which was just recently released.

Currently it is not possible to using a 40Gbps Interfaces as SVL link.  

[gnijs]

Any idea why it isn't supported on the 40G links yet ?
Could it be that both 40G interfaces are terminated on the same ASIC, and therefore not really redundant ?

[roland.sonder]

Just tried to configure it but failed. Activating VSL on a 40G interface triggers an error message saying that this interface is not supported

Hi David,

I too, have same model Cisco 9500-40X series with IOS Image 16.6.2b whereas i am unable to do stackwise virtual configuration. can you please help me with guide.

Thanks

[campbech1]

Upgrade to 16.8. Stackwise-virtual is working on that code release without any issues for us so far.

[Julio E. Moisa]

Hi

As I remember Virtual Stackwise is supported on C9500-24Q only. 

[roland.sonder · Accepted solution]

Starting with release 16.8.1a which has been released April 6th 2018, the feature is now also supported on the following models of the Cisco Catalyst 9500 Series Switches:
C9500-24Q, C9500-12Q, C9500-40X, C9500-16X
Please consider that you can use the 40Gbps interfaces as SVL links yet.
