The new software features for Cisco 1x2 / Compact Shelf RPD Software 6.6 release are:

R-PHY# reboot soft-reset 
Warning: This action will perform a soft reset. Are you sure you want to do the soft reset (yes/no)?yes
SoftReset in 10 seconds

The new software features for Cisco 1x2 / Compact Shelf RPD Software 6.4 release are:

TACACS+ support

Terminal Access Controller Access Control System (TACACS) is a security protocol that provides centralized validation of users who are attempting to gain access to a router or NAS. TACACS+, a more recent version of the original TACACS protocol, provides separate authentication, authorization, and accounting (AAA) services.

Note

RPD can configure 8 TACACS servers at the most. All configured servers use the same secret key. If multiple TACACS servers are configured, RPD will try to connect TACACS server in the order in which the servers are configured until the connection is established successfully. RPD and TACACS server must use same address family.

To enable TACACS+, user needs to setup a TACACS server with secret key configured. Then add this TACACS server's IPv4/IPv6 address and key to RPD configuration.

R-PHY(config)#tacacs add-server 10.0.0.113 
Server '10.0.0.113' is configured on RPD successfully.

R-PHY(config)#tacacs add-key
Please add a secret key:
Please re-enter your secret key:
Add secret key successfully.

User can also delete server and change the secret key.

R-PHY(config)#tacacs delete-server 10.0.0.112
Delete server '10.0.0.112' successfully.

R-PHY(config)#tacacs change-key        
Please change secret key:
Please re-enter your secret key:
Change secret key successfully.

To display the configured TACACS server, use the show tacacs-server command as shown in the following example:

R-PHY#show tacacs-server 
TACACS server configured:
10.0.0.113

RpdInfo read count/read by key support

Starting from Cisco 1x2 / Compact Shelf RPD Software 6.4, TLV 100 RpdInfo read count and read by key is supported.

Spectrum capture support

The upstream triggered spectrum analysis measurement provides a wideband spectrum analyzer function in the CCAP which can be triggered to examine desired upstream transmissions as well as underlying noise or interference during a quiet period. WBFFT stands for Wide Band Fast Fourier Transform. This feature allows all RPD US ports to enable an upstream spectrum analyzer built into the RPD’s front end. RPD supports FreeRunning trigger mode.

Note	US FFT data is computed and sent directly from US PHY. RPD firmware does not handle these data. The firmware configures US PHY to send L2TP stream based on GCP TLV messages.

Please refer to below link for cBR8 configuration about this feature:

https://www.cisco.com/c/en/us/td/docs/cable/cbr/configuration/guide/b_cbr_docsis_full_book_xe16_10/b_cbr_docsis_full_book_xe16_10_chapter_0100110.html

Note	This feature provides a stream of raw spectrum data only. The application that interprets and presents the data in human readable format is not part of this feature.

To verify if the spectrum capture is enabled, use show bcm-register wbfft config command as shown in the following example. The WBFFT Trigger Mode should be FreeRunning if this feature is enabled.

Viavi integration

In this feature, RPD supports non-CCAP defined MAX-HOLD mode for spectrum capture that work with Viavi RCI Agent.

Note	Communications with core is implemented using SNMP. Before using this feature, the NDF/NDR feature must be configured on cBR-8. Viavi RCI Agent needs to be installed and configured on the system with Linux/Ubuntu operating system.

To verify if the spectrum capture is enabled, use show bcm-register wbfft config command as shown in the following example. The WBFFT Trigger Mode should be Other if this feature is enabled.

R-PHY#show bcm-register wbfft config

Soft Enforcement

Soft Enforcement of SEC-AUT-DEFROOT requirement is implemented by printing a warning message and posting warning event 2148075527 during user login process when the default password for admin account is in use.

Below is the warning message that shows up when the default password for admin account is used to login RPD:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Default login credentials detected in use.            
In order to enhance the security of your network,     
default login credentials must be changed on this RPD.
In a future release, this RPD will disable service    
until default credentials are changed.                
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The following table lists the warning event that is triggered when the default password for admin account is used to login RPD:

The new software features for Cisco 1x2 / Compact Shelf RPD Software 6.1 release are:

Disable LLDP by TLV

In Cisco 1x2 / Compact Shelf RPD Software 6.1, LldpEnable TLV is introduced to enable or disable the LLDP protocol. The RPD which supports this attribute MUST preserve the value of this attribute in it non-volatile configuration store.

Value is defined as the boolean value to enable/disable LLDP operation on the RPD. The values are:

• 0 – LLDP is disabled.

• 1 – LLDP is enabled.

The selection of a default value is left to vendor’s choice.

New added events

New events are supported for DHCPv6 and supported networks.

Factory reset support

Starting from Cisco 1x2 / Compact Shelf RPD Software 6.1, factory reset and NVRAM reset via TLV and CLI are supported.

• factoryReset: The device restores the factory configuration and performs a hard reset. You can perform a factoryReset by running the following:

  
  R-PHY>enable 
  R-PHY#reboot factory-reset
  

• nvReset: The device clears non-volatile configuration and performs a hard reset. You can perform a nvReset by running the following:

  
  R-PHY>enable 
  R-PHY#reboot nvreset
  

Support for Narrowband Digital Forward And Narrowband Digital Return

Narrowband Digital Forward (NDF) refers to the digitizing of an analog portion of the downstream spectrum at the headend, sending the digital samples as payload in [DEPI] packets to the RPD, and then re-creating the original analog stream at the RPD. NDF supports services such as FM Broadcast, DAB+ Broadcast, and OOB signals for Forward Sweep, DS Leakage, and Element management.

Narrowband Digital Return (NDR) refers to the digitizing of an analog portion of the upstream spectrum at the RPD, sending the digital samples as payload in [R-UEPI] packets to the CMTS, and then re-creating the original analog stream at the headend. NDR supports legacy OOB signals for Reverse Sweep, Return Path Monitoring, FSK based HMS, and other FSK based telemetry signals.

The following commands are introduced on the Cisco 1x2 / Compact Shelf RPD Software 6.1 release:

• show downstream oob configuration ndf – Provides the NDF configuration in RPD for each NDF channel configured. It displays PHY information for the NDF session.

• show upstream oob configuration ndr – Provides the NDR configuration in RPD for each of NDR channel configured. It displays PHY and L2TP information.

• show downstream oob counter ndf – Provides the NDF packet counter from BCM for each NDF channel configured. It is a clear on read counter.

• show upstream oob counter ndr – Provides the internal mapping of RPD channels and its corresponding channel configured in core.

• show oob fpga ndf-status – Provides the NDF FPGA status for each NDF channel configured.

• show oob ds-mapping – Provides the internal mapping of RPD channels and its corresponding channel configured in the core.
