Information about RPD Reset

Starting from Cisco 1x2 / Compact Shelf RPD Software 6.1, factory reset and NVRAM reset via TLV and CLI are supported. In the factory reset, RPD restores the factory configuration and performs cold reboot. In this case, it is better for the RPD to have golden image, otherwise users need to boot the RPD manually. In the NVRAM reset, RPD clears the non-volatile configuration and performs cold reboot.

Resetting RPD

To clear the configuration, image and logs of the RPD, perform factory reset as shown in the following example:

R-PHY#reboot factory-reset
Warning: This action will restore the factory configuration. Are you sure you want to do the factory reset (yes/no)?

To clear the non-volatile configuration of the RPD, perform NVRAM reset as shown in the following example:

R-PHY#reboot nv-reset
Warning: This action will clear the non-volatile configuration. Are you sure you want to do the nvreset (yes/no)?

Soft-reset

Soft-reset is supported from Cisco 1x2 / Compact Shelf RPD Software 6.6 release. You can perform a soft-reset on the RPD using the RPD CLI or write TLV 40.1.1 (RpdResetCtrl to softReset(1)).

To perform soft-reset using RPD CLI, use the reboot soft-reset command:

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

History of RPD Reset Instances

Cisco RPD supports the ResetHistory (TLV 100.3) object, which provides a record of the occurrences of a reset of an RPD. The RPD can be reset for many reasons, such as a loss of Principal Core, loss of IP connection, power failure, hardware or software failure, or reset command from CCAP Core or CLI.

This ResetHistory object provides details of the conditions that caused the RPD to reset and to assist operators with understanding why a service interruption occured. It also provides details of how much time it took for the RPD to boot its software stack and to become operational with the principal core.


Note

  • If the rebootdisable parameter is set, the RPD does not save any record.

  • If the power cycle is triggered during a reboot, the application is not notified about it. Hence, after recovery, the recovery time and the related information are saved in the latest record. New records are not generated for the power cycle reboot.

  • Recovery time (recoveryTime—TLV 100.31.7)

    • softReset—The recovery time of the soft-reset is the RCP process up-time when the system becomes operational.

    • hardReset/nvReset/factoryReset—The recovery time is the system up-time when the system becomes operational.

  • It stores up to 100 records.

RPD TACACS

The RPD TACACS (Terminal Access Controller Access-Control System) feature is supported from Cisco 1x2 / Compact Shelf RPD Software V7.2 and later. The RPD TACACS feature disables local access if the server is available.

When the TACACS server can be reached from RPD, you can only access the RPD by TACACS account. Local access will be disabled, and you cannot access RPD by local account. But if the TACACS server cannot be reached, for example, due to a wrong server address, network issue, or so on, you can then access RPD by local account.

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. 

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
