Does the Cluster IP need a separate network port?
When the Vendor Engineerset this up, he configured the Cluster IP on a separate Gig-E port (e0L).
But due to limited # of network ports on the switches, I've configured the Cluster IP on the same LACP aggregated 10GbE ports used by the vserver data LIF. Also the Cluster IP is on the same subnet as the Da
Here's my net int show.

A cluster LIF should not be on the same subnet as a management LIF or a data LIF.
The LIF that is used for intracluster traffic. Cluster LIFs can be configured only on cluster ports. Cluster LIFs must always be created on 10-GbE network ports. Note: Cluster LIFs need not be created on 10-GbE network ports in FAS2040 and FAS2220 platforms.

Your question unfortunately sounds very confusing. "Cluster LIF" has very special meaning in cDOT - as already explained it refers to backend interconnect between cluster nodes and it must be on dedicated physical ports that cannot be shared with any other traffic type. But what you actually mean is likely "cluster management LIF". This can share port with any other data and management LIF of any other SVM.
By default cluster management LIF is named cluster_mgmt. Plain "cluster" is rather poor choice as it is highly ambiguous, especially when used as adjective ("cluster IP", "cluster LIF"). On your place I would consider renaming it, e.g. to default cluster_mgmt that makes it obvious what you are speaking about.
And find some time to make yourself familiar with cDOT network organization and terminology
