In order to correct some issues associated with the Pass-Through process on the 
DNCS, some sites have been regularly bouncing this process through scripts that 
reside in the crontab file. This software corrects issues associated with the Pass-
Through process. Therefore, after the upgrade, you should remove any entries in the 
crontab file that reference scripts that bounce the Pass-Through process. The 
instructions in this section guide you through the process of removing these 
references. 

Notes: 

 

Bouncing a process refers to stopping and then restarting that process. 

 

The scripts that Cisco wrote to bounce the Pass-Through process are called 
elop.sh and bouncePassThru. 

 

Follow these instructions to remove entries from the crontab file that reference 
scripts that bounce the Pass-Through process. 
1  If necessary, open an xterm window on the DNCS. 
2  Follow these instructions to check on the presence of scripts in the crontab file 

that bounce the Pass-Through process. 
a  Type crontab  -l  |  grep  -i  elop.sh and then press Enter. The system lists the 

line(s) within the crontab file that contain elop.ksh. 

b  Type crontab  -l  |  grep  -i  bouncePassThru and then press Enter. The 

system lists the line(s) within the crontab file that contain bouncePassThru. 

3  Did the output of step 2 contain any references to the elop.sh or the 

bouncePassThru scripts? 

 

If yes, go to step 4 to remove those references. 

 

If no, then go to Reboot the DNCS (on page 56). 
Note:  You do not have to remove any references to the scripts from the 
crontab file.
