(c) By using a chart similar to that above, convert the “ios.cf” string letter-by-letter to
a decimal value:
i o s . c f
105 111 115 46 99 102
(d) Use the editor of your choice to populate the VSIF field of the DOCSIS
configuration file.
Note You cannot directly enter the decimal of “105.111.115.46.99.102” because this is
only the “value” part of the TLV. What you actually enter is the sub-type of “128” then,
count the length of the word you have chosen for the Cisco IOS image filename.
The “ios.cf” name is used in this example. Thus, the length is 6. Therefore, this is what
you enter in the VSIF field: 128.6.105.111.115.46.99.102.
(e) Save your changes by using the configuration file editor of your choice. Change the
“File Name” field selected in Step 5: for example, bronze.cm, silver.cm, gold.cm,
platinum.cm, to a different value such as:
/tftpboot/gold-ios-config.cm
Note Do not save this file using the same name as the default that served as your starting
point, because this will override the default selected.
(f) After you have saved the file as “gold-ios-config.cm”, then, FTP back to cs and log
in. Make sure you use the binary mode of FTP and choose the file you just created.
(g) Put the file in the /tftpboot (or equivalent) directory of the TFTP server you are using
for your Cisco uBR904 cable access router setup. Enter the following command to
ensure you can TFTP the file:
chmod 777 gold-ios-config.cm
