The four individual transactions supported by the IIH utility can act upon a single 
DHCT or upon a group of DHCTs. When processing a group of DHCTs, system 
operators will find it advantageous to input to the IIH utility a list of DHCT MAC 
addresses as contained in a text file. The information in this section provides 
guidelines and instructions for preparing the text file of MAC addresses. 

 

Use the following guidelines when preparing the input text file: 

 

Prepare the file using a standard text editor, such as vi. 

 

Prepare the file with one MAC address per line. 
Important: MAC addresses must be in hexadecimal format, and any letter 
characters must be uppercase. 
Example:  00:02:DE:4A:11:92 
 

00:02:DE:4A:11:94 

 

Each MAC address or serial number must be left-justified on each line of text. 
Note: A MAC address contains 17 characters. The IIH utility reads only the first 
17 characters of each line. Any additional characters per line are ignored and are 
treated as comments. 

 

Save the file using a name that is relevant to the contents of the file. Append the 
current date to the end of the file name. 
Example: iih-in_11.13.02 for a file that was created on November 13, 2002. 

 

Our engineers recommend that you save the file to the /tmp directory on the 
DNCS. However, files in the /tmp directory are lost whenever the DNCS 
reboots. Store the file here only for one-time use.
