JUNOSe 10.0.3 Release Notes

Configuring the SRC Client to Retrieve DSL Information from Access Nodes
The access node passes the DSL line rate parameters, whenever they change, to the
SRC client. The SRC client appends updated parameters to the COPS messages that
it sends to the COPS server or SRC server. A COPS server processes the following
topology parameters that it receives from the SRC client in the updated COPS
messages:
junoseIpInterfaceMode
junoseIpInterfaceUpstreamRate
junoseIpInterfaceDownstreamRate
junoseIpInterfaceMinimumDataRateUpstream
junoseIpInterfaceMinimumDataRateDownstream
junoseIpInterfaceAttainableDataRateUpstream
junoseIpInterfaceAttainableDataRateDownstream
junoseIpInterfaceMaximumDataRateUpstream

junoseIpInterfaceMinimumLowPowerDataRateUpstream

junoseIpInterfaceMaximumInterleavingDelayUpstream
junoseIpInterfaceActualInterleavingDelayUpstream
junoseIpInterfaceMaximumInterleavingDelayDownstream
junoseIpInterfaceActualInterleavingDelayDownstream

A COPS server that runs an SRC software release earlier than Release 3.0.0 does
not support and process the preceding topology parameters that are appended to
the COPS messages. Such COPS servers analyze the information, other than the
parameters that describe updated DSL line rate details, that they receive in the
COPS messages for policy management. Therefore, the COPS-PR operation ensures
backward compatibility of the SRC clients with the COPS servers running SRC
software releases earlier than Release 3.0.0 by ignoring the received line rate
details.
When you configure the sscc update-policy-request enable command, a warning
message is displayed, prompting you to confirm whether you want to enable the
router that functions as the SRC client to forcibly send updated line rate
information parameters to the COPS server, which is running a release of SRC
software earlier than Release 3.0.0 that is not compatible with the line rate
message format.
