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.

In Remote PHY (R-PHY) configuration, RPDs connect to both active linecard and standby linecard, and have active connections to active linecard, standby connections to standby linecard. From RPD side, it connects to active core and standby core independently.
Each RPD has one principal core, and may have several auxiliary cores. LCHA needs to support multiple cores. These cores are on the same linecard or different linecards. The port on the standby linecard can protect all the same ports on the active linecards.
In the figure above, the RPD has multiple cores connected to the same active linecard. In order to support LCHA, RPD needs to connect to the same port on the standby linecard. In this way, RPD has several standby cores to protect the active cores. The standby core have the same resource as the active core.
When multiple cores connect to different active linecards, if they connect to different ports of the linecard, there will have different standby cores. If active core connects to the same port on different linecard, they share one standby core.
In the figure above, RPD have two standby cores. One standby core connects to port 6 of the standby linecard, it can protect the active core which connects to port 6 of the active linecard 2. The other standby core connects to port 0 of the standby linecard, it can protect the active cores connect to port 0 of linecard 0 and linecard 1. So for the standby core 0, it contains the resource for both active core 0 and active core 1.
When active linecard 0 fails over to standby linecard, the standby core 1 will be deleted, the standby core 0 will bring the resource of active core 0 to active. When linecard 2 fails over to standby linecard, the standby core 0 will be deleted, and standby core 1 will become active for active core 3.

Compared to the SUP high availability recover process in iCMTS configuration, the Remote PHY SUP high availability recover process has RPD status change as shown in the example below:

The status of the RPD changes from recovering to online, indicating that the SUP redundancy is working in the Remote PHY configuration.

This section describes how to configure Remote PHY (R-PHY) Line Card Redundancy on Cisco cBR-8.
The following example shows how to configure DPIC port to support Remote PHY Line Card Redundancy:
Router# configure terminal Router(config)# interface TenGigabitEthernet8/1/0 Router(config-if)# vrf forwarding te80 Router(config-if)# ip address 80.6.16.166 255.255.255.0 Router(config-if)# ip mtu 1500 Router(config-if)# exit Router(config)# interface TenGigabitEthernet8/1/1 Router(config-if)# vrf forwarding te81 Router(config-if)# ip address 80.6.16.167 255.255.255.0 Router(config-if)# ip mtu 1500 Router(config-if)# exit Router(config)# interface TenGigabitEthernet6/1/0 Router(config-if)# vrf forwarding te60 Router(config-if)# ip address 80.6.16.186 255.255.255.0 Router(config-if)# ip mtu 1500 Router(config-if)# exit Router(config)# interface TenGigabitEthernet6/1/1 Router(config-if)# vrf forwarding te61 Router(config-if)# ip address 80.6.16.187 255.255.255.0 Router(config-if)# ip mtu 1500
The following example shows how to configure RPD to support Remote PHY Line Card Redundancy:
Router# configure terminal Router(config)# cable rpd node1 Router(config-rpd)# identifier 0004.9f03.0055 Router(config-rpd)# core-interface te8/1/0 Router(config-rpd-core)# principal Router(config-rpd-core)# rpd-ds 0 downstream-cable 8/1/0 profile 0 Router(config-rpd-core)# rpd-us 0 upstream-cable 8/1/0 profile 0 Router(config-rpd-core)# exit Router(config-rpd)# core-interface te8/1/1 Router(config-rpd-core)# rpd-ds 0 downstream-cable 8/1/1 profile 0 Router(config-rpd-core)# rpd-us 0 upstream-cable 8/1/1 profile 0 Router(config-rpd-core)# exit Router(config-rpd)# exit Router(config)# cable rpd node2 Router(config-rpd)# identifier 0004.9f03.0163 Router(config-rpd)# core-interface te8/1/2 Router(config-rpd-core)# principal Router(config-rpd-core)# rpd-ds 0 downstream-cable 8/0/1 profile 1 Router(config-rpd-core)# rpd-us 0 upstream-cable 8/0/2 profile 2
The following example shows how to configure Remote PHY Line Card Redundancy:
Router# configure terminal Router(config)# redundancy Router(config-red)# mode sso Router(config-red)# linecard-group 0 internal-switch Router(config-red-lc)# class 1:N Router(config-red-lc)# member slot 8 primary Router(config-red-lc)# member slot 6 secondary Router(config-red-lc)# no revertive
To verify the Remote PHY line card redundancy configuration, use the example below:
Router# show redundancy linecard all LC My Peer Peer Peer Slot Subslot Group State State Slot Subslot Role Mode --------------------------------------------------------------------------------- 8 - 0 Active Stdby Warm 6 - Active Primary 6 - 0 - - Multiple None Standby Secondary Router# show cable rpd lcha-cores MAC Address IP Address I/F State Core Role HA Role 0004.9f03.0055 80.6.16.15 Te6/1/0 online Principal Standby 0004.9f03.0055 80.6.16.15 Te8/1/0 online Principal Active 0004.9f03.0163 80.6.16.16 Te6/1/1 online Principal Standby 0004.9f03.0163 80.6.16.16 Te8/1/1 online Principal Active Router# show cable rpd MAC Address IP Address I/F State Core Role HA Role 0004.9f03.0055 80.6.16.15 Te6/1/0 online Principal Active 0004.9f03.0163 80.6.16.16 Te6/1/1 online Principal Active
