Vol. VI-B-50 Alcatel-Lucent
• Use the Rx and Tx count registers in CT System/Controls to determine which
ports are carrying most traffic, and from this, based on the operational mode
selected in the DAC ES or DAC GE plug-ins screen, determine which channel
is primarily affected (requires additional bandwidth).
• If traffic requirements have changed since the DAC ES or DAC GE was first
configured, also review port priority selections. When frames are being
dropped, it is likely that traffic assigned on lowest priority ports will be most
affected.
Additional Information
When buffer space runs out, frames will be dropped, and a dropped-frame
counter increments to provide the ratio count of dropped frames to total frames.
DAC GE Alarms
ICPU Failure
No communications with the electrical or optical transceiver module. This is a
critical alarm.
Probable Cause
Equipment malfunction.
Recommended Actions
Withdraw the DAC GE, pause, then reinsert.
Replace the DAC GE.
ICPU Software Failure
The DAC GE processor software is unavailable or unstable. This is a major
alarm.
Probable Cause
There is a version mismatch in the CPU software.
Recommended Actions
DAC GE requires SW release 3.1 or later. SW must be upgraded to to 3.4 or later
to secure access to RWPR and to advanced link aggregation.
Replace the DAC GE.
