does rebooting a vcenter or if a vcenter is down affect existing port channels created with the web client? what happens to the port channel when vcenter i ddown?

DV switch control plane is with vCenter server, which allows me to create, configure and manage DV Switch. But when hosts gets attached with it, Data Plane is alway with hosts, so if you have created LAG etc... during unavailability of vCenter server (like while rebooting or such other short term down time) functionality will continue to work.

it's just that if you want to modify something in your existing DV Switch configuration, then you will be troubled.

Distributed Switch has this name because the switch is in vCenter but a "copy" of switch runs in each host, so, a boot on vcenter does not affect esxi. See that you can migrate your vcenter to another host without downtime in your environment.

Hi,

no this doesn't affect the port channels. The port channels are configured on the physical switch, so there is no dependancy with the vCenter. Standard switches are configured on the ESXi host. A distributed Switch is configured and the config is stored on the vCenter, but there is a copy of the dvSwitch config on the ESXi host.

You can safely reboot your vCenter VM.
