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.
Your software release may not support all the features documented in this module. For the latest feature information and caveats, see the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the Feature Information Table at the end of this document.
Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to http://tools.cisco.com/ITDIT/CFN/. An account on http://www.cisco.com/ is not required.
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. |
Remote PHY device bring up process is prerequisite to the operation of the remote PHY system, just like the cable modem bring up in a DOCSIS system.
This section describes how to bring up RPD on Cisco cBR-8.
To configure DHCP server, follow the steps below:
To configure PTP, use the following example as reference:
On cBR-8 router:
interface Loopback1588 ip address 159.159.159.4 255.255.255.255 interface TenGigabitEthernet5/1/3 /* connect to ASR903 */ ip address 192.104.10.4 255.255.255.0 ip route 10.90.3.93 255.255.255.255 192.104.10.93 /* route to ASR903 loopback ip */ ptp clock ordinary domain 0 servo tracking-type R-DTI clock-port slave-from-903 slave delay-req interval -4 sync interval -5 sync one-step transport ipv4 unicast interface Lo1588 negotiation clock source 10.90.3.93 /* ASR903 loopback ip */ ptp r-dti 1 ptp-domain 0 /* same domain number with ptp server */ clock-port 1 ethernet 1 /* default value is same index with clock-port index, for RPD, ethernet 1=vbh0, ethernet 2=vbh1 */ clock-source 10.90.3.93 gateway 93.3.10.2 /* clock-source is ASR093 loopback ip, gateway is ASR903 BDI ID for node */
On ASR903 router as PTP master:

To configure the cBR-8 to bring up the RPD, use the following example as reference:
