Hi I'm testing mpss 3.4. 

I'm flowing the manual, System Administration for the Intel® Xeon Phi™ Coprocessor . 

https://software.intel.com/sites/default/files/managed/bd/53/
System_Administration_Guide_Intel(R)XeonPhi(TM)Coprocessor.pdf

I installed mpss with rpm. and set the network as below. 

# micctrl --addbridge=br0 --type=External --ip=192.168.10.32 --netbits=24 mic0
# micctrl  --network=static --bridge=br0 --ip=192.168.10.132 --netbits=24 mic0

and I found the setting is at the last line of the /etc/sysconfig/mic/default.conf

Bridge br0 External 192.168.10.32 24 1500

and, in the /opt/intel/mic/filesystem/mic0/etc/sysconfig/network/ifcfg-mic0  .

IPADDR=192.168.10.132
GATEWAY=192.168.10.32
PREFIX=24
MTU=1500

however, after "  micctrl --initdefaults  " and " /etc/init.d/mpss start " , the mic cannot be connected by ssh. I've been just seeing the message "ssh: connect to host node0xx-mic0 port 22: No route to host" . 

Sorry for poor English. It would be good if I get the answer in short time. 

Thank you for reading.

It is solved. But I don't know the reason. 

I just uninstall hole mpss rpms following the "System Administration for the Intel® Xeon Phi™ Coprocessor".

I am glad you solved your problem. In thinking about what might have gone wrong - it looks like you might not have run 'micctrl --initdefaults' before you ran 'micctrl --addbridge'. In MPSS 3.4, the file default.conf lives in /etc/mpss rather than /etc/sysconfig/mic. So, what I think happened is that some of the information was in the right location and some was in the wrong location, causing the network not to be set up correctly. Once you had run initdefaults, reinstalling the MPSS set things right.

For installing the MPSS, it is generally best to follow the readme file that comes with the MPSS for the basic install and then refer to the MPSS User's Guide (or the system admin guide - although I expect it to go away at some point, in favor of the User's Guide.)
