The stack names are not predefined, you should be able to create a stack using any name. 

However, the type attribute, both for the transport add operation 
{noformat}
/subsystem=jgroups/stack=fred/transport=TRANSPORT:add(type=udp)
{noformat}

and for the protocol add opertation

{noformat}
/subsystem=jgroups/stack=fred:add-protocol(type=MPING)
{noformat}

are predefined, up to a point. The values for the transport are from a set {udp, tcp, tunnel} and the values for the latter are a larger set {mping, ping, frag, ...} which are the set of allowable JGroups protocol layers (version dependent). The problem with setting up validators for these attributes is that they rule out users supplying their own custom protocol layers, so we decided against validating them.

The problem of creating stacks is described in the linked issue.
