Information about DEPI/UEPI/L2TP integration with RPD
DEPI
Downstream External PHY Interface (DEPI) is the downstream interface between the CCAP Core and the
RPD. R-DEPI is based on DEPI. More specifically, it is an IP pseudowire between the MAC and PHY in an
MHAv2 system that contains both a data path for DOCSIS frames, video packets, and OOB packets, as well
as a control path for setting up, maintaining, and tearing down sessions.
UEPI
Upstream External PHY Interface (UEPI) is the upstream interface between the RPD and the CCAP Core.
Like DEPI, it is an IP pseudowire between the PHY and MAC in an MHAv2 system that contains both a data
path for DOCSIS frames, and a control path for setting up, maintaining, and tearing down sessions.
How to Configure DEPI/UEPI/L2TP integration with RPD
This section describes how to configure DEPI/UEPI/L2TP integration with RPD.
Configuring depi-class/l2tp-class Pair
It's not permitted to change the default l2tp-class configuration (rphy-l2tp-global-class) for R-DEPI by user,
because the parameter values are fine tuned to accommodate most common cases.
If user wants to use parameter values other than the default ones, they can use manually defined
depi-class/l2tp-class pair. To do so, follow the example below:
Router# configure terminal
Router(config)# l2tp-class l2tp_demo
Router(config-l2tp-class)#exit
Router(config)# depi-class depi_demo
Router(config-depi-class)#l2tp-class l2tp_demo
Router(config-depi-class)#exit
Router(config)#cable rpd node
Router(config-rpd)#core-interface Te1/1/7
Router(config-rpd-core)#depi depi_demo /* Be sure to configure when the RPD core is offline*/
Router(config-rpd-core)#end
Verifying depi-class/l2tp-class Pair Configuration
To verifying depi-class/l2tp-class pair configuration, use the show running-config command as shown in the
example below:
Router#
alias exec scr show cable rpd
cable rpd node
identifier 0004.9f00.0901
core-interface Te1/1/7
principal
rpd-ds 0 downstream-cable 1/0/31 profile 155
