Cisco 3850 Stackwise virtual issu

[adnanbiek]

I have two cisco 3850 mode ws-c3850-12XS-E with to 4 10G network module.

I have setup cisco stackwise virtual on those swithes via to 10G link as SVL link and one 10G as dual active detection and two switches have been stacked. I connect two 1G link from cisco 2960 switch to those cisco 3850 stacked switches,but when I setup LACP between those link the below error was appear:

l3dontbndl2: te1/1/4 suspended: lacp currently not enabled on the remote port

but now I do not know what is problem. everything for config is ok.

another thing when I unplug one link from SVL that problem will be solved.

please help me

How is this possible?   

According to Cisco documentation (02 July 2017) it states:  

Cisco StackWise Virtual is supported only on the WS-C3850-48XS-S, WS-C3850-48XS-E, WS-C3850-48XS-F-S, WS-C3850-48XS-F-E models of the Cisco Catalyst 3850 Series Switches.

Yes is supported only on the WS-C3850-48XS-S, WS-C3850-48XS-E, WS-C3850-48XS-F-S, WS-C3850-48XS-F-E models of the Cisco Catalyst 3850 Series Switches. but now it is working on WS-C3850-12S-E. swithes were stacked. all feature for stack is working but only LACP problem.

Are you sure your two switches are successfully stacked?  If they were, I'd expect a single stack configuration rather than two separate switch configurations.

The command reference states that the link value of "stackwise-virtual link <link value>" should match the stackwise virtual domain. Yours shows a mismatch. That's something to fix if you're still wrestling with the problem.

Hi  cweinhold

 Thanks so much for your comment.

 could you please me what exact my problem?(syntax).

now i see i should put each link of stackwise virtual link in different value?

is that correct?
