Not sure about what you want.
Opening a port is usually more a firewall task. If you are really asking about enabling a service, use the svcadm command if managed by smf or just launch the daemon listening to that port. /etc/service setting isn't mandatory.

NAME
nfs4cbd - NFS Version 4 callback daemon SYNOPSIS
/usr/lib/nfs/nfs4cbd The nfs4cbd daemon manages communication endpoints for the NFS Version 4 protocol callback program. nfs4cbd runs on the NFS Version 4 client and creates a listener port for each transport over which callbacks can be sent. The nfs4cbd daemon is provided for the exclusive use of the NFS version 4 client. See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWnfscu | +-----------------------------+-----------------------------+ svcs(1), mount_nfs(1M), svcadm(1M), attributes(5), smf(5) The nfs4cbd service is managed by the service management facility, smf(5), under the service identifier: svc:/network/nfs/cbd Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser- vice's status can be queried using the svcs(1) command. If it is disabled, it will be enabled by mount_nfs(1M) and automountd(1M) on the first NFSv4 mount, unless its application/auto_enable property is set to false. This daemon might not exist in a future release of Solaris. 11 Apr 2005 nfs4cbd(1M)
