Known Affected Releases

4.3.0.BASE

Description (partial)

Symptom:
When the line protocol is down on the serial HDLC or PPP link the CPP continues to forward
traffic and accept packets.

while this is generally not an issue, the problem is that Y cable redundancy sees packet duplication.

Conditions:
serial PPP/HDLC links on the SIP700 with a lineprotocol down

ASR9000/XR - Disk Mirroring causing RSP crash / corruption
We are in the process of troubleshooting disk mirroring on our RSP440-TR's.  Every time we enable, the RSP crashes.   Detailed information on the three (3) scenarios and log results are listed below.   I'm curious if disk mirroring is necessary on our ASR9k's.  I've read various posts that reference that there's no purpose to disk mirroring at all along with the following bug CSCus34978 where it references the RSP going corrupt after enabling disk mirroring.   https://tools.cisco.com/bugsearch/bug/CSCus34978  ...
