How to check CIFS mount options on Linux

On a Linux server, I see a CIFS filesystem mounted. It was mounted through command-line so it doesn't have entry in /etc/fstab and I dont have access to NAS server which shares the filesystem through CIFS. How can I check with what options that CIFS filesystem are mounted ?
Is that possible ?  Please let me know.

"mount" seems to be showing the options. It is showing it as (rw, mand), any idea what is this "mand" denotes ?


[root@ftpllm01 testimsftp]# mount
/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/xvda1 on /boot type ext3 (rw)
tmpfs on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
//nasllm01-ims/ims_websites on /nasftp type cifs (rw,mand)
//nasllmha-ims/ims_websites on /NASfrom3par_CIFS type cifs (rw,mand)

That's "mandatory locking" (= kernel enforced file locking), which is standard  with CIFS as opposed to "advisory locking" (= cooperative file locking)  which is the NFS standard.
