The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. Learn more about how Cisco is using Inclusive Language.
This document describes the RPD operations and debugging of an RPD.
Note | The hardware components introduced in a given Cisco Remote PHY Device Software Release are supported in all subsequent releases unless otherwise specified. |
Note | The -PKEY suffix in the PID indicates units that enable the SCTE-55-2 Out-of-Band protocol support. |
The operators might need secure remote access to the RPD for activities such as setting up the RPD before the installation, maintenance, or troubleshooting. The RPD supports Secure Shell (SSH) server that allows secure access to the RPD.
The following prerequisites are applicable for debugging or checking RPD operations:
RPD has established GCP connection with the CCAP-core, and RPD IP address is retrievable from CCAP-core.
RPD is assigned an IP address through the DHCP process, and the IP address is retrievable from the DHCP server.
Note | To know more about the commands referenced in this module, see the Cisco IOS Master Command List. |
SECURITY WARNING: ssh password login is accessible! Please use pubkey login and set password login off!The following procedure shows how to use SSH to access RPD without password from NMS.
Check whether NMS already has an SSH key. If yes, do not generate a new key.
cat ~/.ssh/id_rsa.pub ssh-keygen -t rsa
ssh pubkey add ? LINE NMS's pubkey
ssh -l admin <RPD ip>
R-PHY#conf t R-PHY(config)#ssh password ? off disable ssh password login on enable ssh password login R-PHY(config)#ssh password off R-PHY(config)#end
Use the following procedure to debug RPD:
Disable RPD auto reboot by setting the reboot hold.
R-PHY# set reboot hold
Secure copy the logs of RPD to the server using the following command.
logging provision-archive scp server_ip user_id dst_location
Collect the show CLI output.
For RPD online issues, check which status is failed. You can check the following outputs:
show provision all
show provision history
show dot1x detail
show dhcp
show tod
show ptp clock 0 config
show ptp clock 0 state
For modem online issue, check ds/us config and l2tp session.
You can collect the following outputs:
show downstream channel configuration
show downstream channel counter dps (show multiple times)
show downstream depi configuration
show upstream channel configuration <port number> <channel number>
show upstream iuc counter <port number> <channel number> (show multiple times)
show upstream map counter <port number> <channel number> (show multiple times)
show upstream uepi configuration
show l2tp tunnel
show l2tp session
R-PHY#clear reboot hold
R-PHY#show ssh session connected session: 1 ssh password auth: off ssh NMS pubkey num: 1 R-PHY#
This section provides example for the fault management configuration on R-PHY.
