Hardware Compatibility Matrix for Cisco Remote PHY Device
![]() Note | The hardware components introduced in a given Cisco Remote PHY Device Software Release are supported in all subsequent releases unless otherwise specified. |
Information about RPD Bring Up
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.
How to Bring Up RPD
This section describes how to bring up RPD on Cisco cBR-8.
Configuring DHCP Server
To configure DHCP server, follow the steps below:
Configuring PTP
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:
ptp clock ordinary domain 0 clock-port Master-to-all-cBR8 master sync interval -5 sync one-step transport ipv4 unicast interface Lo1588 negotiation interface Loopback1588 ip address 10.90.3.93 255.255.255.255 interface GigabitEthernet0/3/5 no ip address negotiation auto cdp enable service instance 31 ethernet /* 31 is vlan id */ encapsulation dot1q 31 rewrite ingress tag pop 1 symmetric bridge-domain 31 service instance 32 ethernet encapsulation dot1q 32 rewrite ingress tag pop 1 symmetric bridge-domain 32 interface BDI31 /* for cBR, SUP PIC */ ip address 192.104.10.93 255.255.255.0 no shut interface BDI32 /* For RPD */ ip address 93.3.10.2 255.255.255.0 no shut ip route 159.159.159.4 255.255.255.255 192.104.10.48 /* route to cbr-8 loopback ip */
Configuring cBR-8
To configure the cBR-8 to bring up the RPD, use the following example as reference:
/* D-PIC TenGiga interface config */
interface TenGigabitEthernet0/1/0
ip address 93.3.10.1 255.255.255.0
ip helper-address 20.1.0.33
