I got a mail off list which pretty much explains it :) fpd version 1.17 seems to affect tengig 0/0/2/2 and 0/0/2/3 (Which are the ports i moved the link between). The IOS XR 5.3.1 contains 1.18 BUT - somebody updated this machine without reading the multi-page-update-description which mentions "fpd auto-upgrade". So nobody updated the fpd to match the current IOS XR - so - although 5.3.1 is unaffected by the bug - this machine still is due to incomplete upgrade. Fix for ASR9001 port flap issue CSCug60558 Description Symptom: ASR9001 seeing front panel ports 2 and 3 going down without any trigger. Ports remains down with Tx disable until they are shut/no shut. Affected: Ten 0/0/2/2 Ten 0/0/2/3 Unaffected: Ten 0/0/2/0 Ten 0/0/2/1 -- Florian Lohoff f...@zz.de UTF-8 Test: The 🐈 ran after a 🐁, but the 🐁 ran away
