We are currently running L2 svs mode in the lab and I would like to change to L3 mode with the specific configuration additons below. (not worried about a dedicated control vlan at the moment since this is functional testing).
My question is, will there be any impact to moving to L3 svs mode? I am expecting this change to only impact control traffic between the VSM and VEM. We currently have mutliple networks/vlans trunked in on the uplink and I don't want to impact the switching behavior there.
Yes you are right. Its only for how the VSM and VEM will communicate.
Addition to svs mode, the control vlan and packet vlan config in svs-domain should be removed using the commands "no control vlan" and "no packet vlan".
no control vlan
no packet vlan
svs mode L3 interface mgmt0
Before making the svs-domain config change you will need to disconnect the svs connection to vCenter, make the changes and then re-connect it. A detailed migration guide is availalble in the below link.
