Red Hat Bugzilla – Bug 1011022
Auto delay mechanism doesn't work with P2P
Last modified: 2015-07-19 20:55:15 EDT
Description of problem:
When ptp4l is configured to use the Auto delay mechanism and it receives a P2P request when the E2E delay timer is not running, it will switch to P2P, but not make any P2P requests itself.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. run ptp4l master with P2P
2. run ptp4l slave with Auto
3. monitor slave log
ptp4l not making any clock updates
ptp4l reporting master offsets and making clock updates
This is fixed by upstream commit b366b79306f0d5d8c7da0ae10acdca2b01cb54fe.
