[USRP-users] USRP source channel bandwidth setting with GRC

I am using the GRC USRP source, wonder how could I set the RF front end bandwidth on the USRP device. I have been trying ajusting the bandwidth parameter but it did not seem to have any effect. The  device I have X310 WBX-120. 

The following is from GRC documentation but it is not very clear to me. 

To use the default bandwidth filter setting, this should be zero. Only certain subdevices have configurable bandwidth filters. See the daughterboard application notes for possible configurations.
