Modifying the Subscriber Configuration

To locate the CMTS device associated with a subscriber, the JPS maps the subscriber IP address in a message to the CMTS IP address to which the message must be delivered. This mapping specifies the subscriber IP pools associated with CMTS devices.

Use the following configuration statements to configure a CMTS device to which the JPS can connect and the pools of subscriber IP addresses that are managed by the CMTS device:

slot number jps cmts-registry cmts cmts-ip ... 

slot number jps cmts-registry cmts cmts-ip range-pool pool-index { 
    low low; 
    high high; 
} 

slot number jps cmts-registry cmts cmts-ip subnet-pool subnet { 
    exclude [exclude]; 
} 

Configuring Subscriber IP Pools as IP Address Ranges

To configure subscriber IP pools that are managed by the CMTS device as IP address ranges:

  1. From configuration mode, access the configuration statement that configures the CMTS device to which the JPS can connect.
  2. user@host# edit slot 0 jps cmts-registry cmts cmts-ip range-pool pool-index 
    
    
    

Specify the IP address of the CMTS device and the address range pool index.

  1. Specify the first IP address in the IP range for the pool of subscriber IP addresses that are managed by the CMTS device.
  2. [edit slot 0 jps cmts-registry cmts cmts-ip range-pool pool-index] 
    
    user@host# set low low 
    
    
    
  3. Specify the last IP address in the IP range for the pool of subscriber IP addresses that are managed by the CMTS device.
  4. [edit slot 0 jps cmts-registry cmts cmts-ip range-pool pool-index] 
    
    user@host# set high high 
    
    
    
  5. (Optional) Verify your configuration.
  6. [edit slot 0 jps cmts-registry] 
    
    user@host# show 
    

Configuring Subscriber IP Pools as IP Subnets

To configure subscriber IP pools that are managed by the CMTS device as IP subnets:

  1. From configuration mode, access the configuration statement that configures the CMTS device to which the JPS can connect.
  2. user@host# edit slot 0 jps cmts-registry cmts cmts-ip subnet-pool subnet 
    
    
    

Specify the IP address of the CMTS device and the IP address and mask of the subnet for the pool of subscriber IP addresses.

  1. (Optional) Specify the IP addresses of the subnet that are excluded from the subscriber IP pool managed by the CMTS device.
  2. [edit slot 0 jps cmts-registry cmts cmts-ip subnet-pool subnet] 
    
    user@host# set exclude [exclude...] 
    
    
    
  3. (Optional) Verify your configuration.
  4. [edit slot 0 jps cmts-registry] 
    
    user@host# show
