Absence of Stackwise-Virtual link 1 in Switch 1

[ferdievicmudo]

Switch 1 - Stackwise-virtual link1  was removed automatically the port te1/0/23 and 24 have a stackwise config but after the data loop issue the config was removed

Switch 2  - Stackwise-virtual link1was still present and up

The issue is the stackwise configuration of the switch 1 and switch is to is not working therefore all of the Portchannel encounters data flapping and the switches disabled one of the redundant link via LACP to avoid data loop.

Someone help me how to configure the stackwise-virtual in link 1 because when I'm trying this config

Switch1#(config) int range te1/0/23-24

Switch1#(config) stackwise-virtual link 1 

theres an error that I cannot provision the stackwise to a remote switch

Thanks in advance

What is the role of the  each device after they broken from SVL ?

Right now I haven't reconfigured it yet. There's a multiple port channels for the uplink for each access switches in various department.

The port was disabled by the LACP in all access switches. Some vlans are affected by this issue, because of the absence of the stackwise-virtual link configuration theres a multiple data loop in our switches. I've heard that it is a bug from cisco ios that there's  an issue that the stackwise-virtual link config suddenly removed automatically.
