I know the 4100 has a diag page, it just doesn't show the upload/download speeds, i do see this a lot in the log:
Code:
061210115226 7-Information H501.6HFC: TRC SYNC Recovery OK
061210115224 3-Critical H501.4HFC: LOST TRC SYNC- trying to recover
061210115224 7-Information H501.12HFC: FEC LOCK recovery OK
061210115224 3-Critical T5.0SYNC Timing Synchronization failure - Loss of Sync
But can't see the E102.0 entry mentioned.
