Environment and system tools
xra31-admin: It is not possible to follow the system/service logs
Analysis
- Captured packets are not ordered by timestamp
Changelog 1.1.2-417 (2018-06-05)
Improvements
-
System and services
- The user can now obtain the customer information either via command-line (
xra31-admin customer-info) or via the WebAdmin System page.
- Fixed some typo's in error messages.
-
WebAdmin (GUI)
- Added feedback bar after creating support archive.
- Status is refreshed more frequently.
- Some minor graphical changes (more compact tables, position of icons).
- Added more tooltips.
-
Wireshark
- Update to Wireshark 2.4.6
- Added UCD reassembly
Bugfixes
-
System and services
- Fixed selection of OFDMA channels when more than one is available.
- Bugfix in reporting of input level when channel power is too low.
- No longer invalidating the lock status for all OFDM profiles when one profile loses MAC lock.
- Fixed possible erroneous packets due to race conditions in buffering.
-
WebAdmin (GUI)
- Fixed issue where edited parameters were displayed in the status bar before apply.
- Fixed incorrect MER shown in status bar when the OFDM channel had PLC-only lock.
- Fixed stability issue (status no longer fetched when something went wrong).
Known Issues
-
System and services
- Upstream synchronization may fail in certain downstream channel bonding configurations.
-
WebAdmin (GUI)
- Upload progress bar not does correctly display full upload process progress
- In some rare occasions, selecting a different OFDMA channel fails (workaround = select and apply again)
Changelog 1.1-285 (2018-04-11)
Changes
-
General
- Re-defined the lock state of the downstream channels
- No lock
- PLC-only lock
- Full lock
- Capturing is now allowed even when the downstream channel has no lock or PLC-only lock.
- The PLC MER is now available.
-
FPGA
- Reinitialize OFDM channel after self-test
- Added extra OFDM channel status flags
- Fixed amplifier communication lockup
-
Wireshark
- Update to Wireshark 2.4.5
- Added expert info in case XRA payload is non-existent
- Made sure UCD embedded in REGRSPMP does not overwrite REGRSPMP info
- Fixed profile mapping
-
WebAdmin (GUI)
- System page has been finalized
- Fixed download button of support archive
- Added sorting on columns
- Analyze page
- Fixed download of capture via download button
- Added sorting on columns
- Capture page
- Automatically adding .pcap extension to capture file
- Selection dialogs have been moved for better visibility
- Overall small bug fixes and look and feel.
-
System
- The xra31 user can now reset the state of the firmware self-test.
- In case of firmware update failure the state can be reset so that a firmware update will be retried on next reboot.
- The FPGA firmware is now forced to reboot when the system reboots.
Known Issues
-
WebAdmin (GUI)
- Sometimes the status shows a warning about the input level while the input level is OK.
- Delete confirm dialog disappears after two seconds.
- When editing PLC frequency value this appears in the status bar.
- There's no confirmation when creating support archive.
- Tooltip texts are not available everywhere yet.
- The GUI rarely gets in a state showing "object not found" and "no more channel receivers available" errors
-
Daemon
- The lock status for all OFDM profiles is invalidated when one profile loses MAC lock
