Adding Subnet Option Sets

You can use the Add Subnet Option Set page (see Figure 9-4) to define a new subnet option set.

Figure 9-4: Add Subnet Option Set Page

To add a subnet option set, do the following:

Step 1 Log in to Modem Registrar.

Step 2 On the Main Menu page, click Option Sets.

Step 3 On the Configure Option Sets page, click Subnet.

Step 4 On the Subnet Option Set List page, click Add Option Set.

Step 5 On the Add Subnet Option Set page, enter the name of the new subnet option set in the Subnet Option Set Name field. This name must be unique.

For example: 161.44.133.0/24

where 161.44.133.0 is the IP address and 24 is the subnet mask .

The subnet option set name must be composed of an IP address , a forward slash, and a subnet mask number. For example:

where:

<ipaddress> has the format aaa.bbb.ccc.ddd, where aaa, bbb, ccc, and ddd are all integers:

: 0 is less than aaa and aaa is less than 224
: 0 is less than or equal to bbb and bbb is less than or equal to 255
: 0 is less than or equal to ccc and ccc is less than or equal to 255
: 0 is less than or equal to ddd and ddd is less than or equal to 255

<mask> is an integer.

Step 6 Select the CMTS that will service this subnet from the Servicing CMTS pull-down list.

Note

Step 7 Enter a description of the new subnet option set in the Description field to further identify it. This field is optional. You can choose to leave this field blank.

Step 8 Click OK to add the new option set.

If the new subnet option set name you entered and all of the other information you entered are valid, the new option set is added and the Subnet Option Set List page appears.

If any of the information is invalid, a message appears asking you to correct the invalid information.

Note Modem Registrar does type and value checking to validate
