OpenManage Enterprise - Automation - Add VLAN to Uplink without network disruption
Having an issue with adding a VLAN to a chassis group Smart Fabric uplinks. Using the following OpenManage Enterprise API:
/api/NetworkService/Fabrics(Id)/Uplinks(Id)
PUT method for Uplinks(Id)
Documentation Link
If we use the above API to add one new VLAN to the uplink (that already has 550 existing VLANS enabled on it), the API will disable all 550 VLANs attached to that uplink and just adds/enables the one new VLAN.
If we send the above API call passing all 550 VLANs that are on the uplink plus the new VLAN, it will re-add all of them, but it will blip the existing VLANs for a moment on the ESXi (VMware) host...which is not good since it causes a network disruption by hiccuping.
We have dug into the OpenManage Enterprise APIs to see how we can add/enable just the one new VLAN without experiencing one of the issues above. Is there an API we are unaware of that will allow us to add one VLAN to the chassis group Smart Fabric Uplinks without causing a network hiccup?
Thank you!
