VLT interface links spanning tree
Hi,
I followed this guide to setup a standard VLT configuration between two S4112 switches.
I have 2 100g dac cables configured as the disocvery interfaces.
When I plug in the second DAC cable spanning tree seems to go crazy and after a few minutes the switches have frozen.
SAH-CORE1# show spanning-tree brief
Spanning tree enabled protocol rapid-pvst with force-version rstp
I note that when i run show spanning tree brief, the discovery interfaces are not present. Is there something specific i need to run to prevent spanning tree with the VLT interfaces?

Hi, I checked below two articles. Please be sure of these steps. VLTi interface manages VLAN tagged/untagged traffic automatically between peers1. Manually adding any VLAN configuration has been shown to disrupt traffic flow. If a VLAN configuration has been added to the VLTi, the recommended recovery procedure is as follows for both VLT members:
