Many NFS servers only support UDP. udp Mount the NFS filesystem using the UDP protocol. This is the default. Expected results: Tcp should be listed as the default protocol.

Network File System (NFS) http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/sysadmin-guide/s1-nfs-mount.html 22.2.3. Using TCP The default transport protocol for NFSv4 is TCP; however, the Red Hat Enterprise Linux 4 kernel includes support for NFS over UDP. To use NFS over UDP, include the -o udp option to mount when mounting the NFS-exported file system on the client system.
