The multicast IP address is calculated based on the base radio and comparator pairing number and
the formula as follows:
For Conventional Systems:
224.10.100.nnn, where nnn is: (2 * channel number) - 1 for channel number between [1, 127]
224.10.101.nnn, where nnn is: (2 * (channel number – 127) - 1) for a channel number between [128,
200]
For Trunked Multi-Site Systems:
224.100.102.nnn, where nnn is: 100 + (2 * channel number) - 1
NOTICE: The BR/CM Pairing Number
is not used for circuit (V.24 or 4-wire/V.24 hybrid link)
configurations.
See Setting the Device IP Address and Pairing Number in CSS
on page 138 to set the pairing number.
The pairing number can also be set using an Ethernet connection. See Setting the BR/CM Pairing
Number in CSS on page 143.
4.4.3.3
Serial Security Services in CSS
The Serial Security Services in Configuration/Service Software (CSS) enables the secure services and
changes the device password.
NOTICE: The Serial Security Services must be set before changing the SNMPv3 configuration
and user credentials on a selected device in the site.
Before enabling this parameter, any login and password may be used on the File Transfer Access
Services login window to access a device. After Authentication Services are enabled, the login and
password provided is checked against the following authentication sources:
Stored password
RF site devices support a configurable password for the Local Service and Elevated Privileges
accounts. The password is verified against the stored password for these accounts.
Built-in logins and passwords
RF site devices support built-in login/password combinations for a login by services such as the
software downloads. Only certain software download login names are authenticated in this way.
Centralized Authentication
For authentication through centralized accounts instead of Local Service, Elevated Privileges, and
built-in user accounts, use the Configure the Centralized Authentication parameter in CSS for
the Challenge Handshake Authentication Protocol (CHAP). See “Enabling/Disabling Centralized
Authentication with CSS” in the Authentication Services manual. This procedure requires an
Ethernet connection to the device being configured.
4.4.3.3.1
Setting the Serial Security Services in CSS
Prerequisites: Obtain the required credentials information (local service account password and
elevated privileges password) to configure the site devices before proceeding. The user credentials
information includes both the current and new credentials. Without the current credentials, you cannot
access the device and cannot change the user credentials. See Local Password and SNMPv3
Passphrase Troubleshooting
on page 219. Changing to the incorrect user credentials may lead to not
being able to access the device through Configuration/Service Software (CSS) or Secure Shell (SSH).
