CLAN-BD (Control LAN Circuit Pack)
Issue 4 May 2002
10-397 555-233-123
l. Error Type 2305-2306: Error in received frame from packet bus.
Most likely cause—packet bus problem.
Other cause—circuit pack fault.
Invalid LAPD frame errors occur when the frame
■ contains a bad Cyclic Redundancy Check (CRC),
■ is greater than the maximum length,
■ violates the link level protocol.
1. Retry the command (test board UUCSS) and see if the condition
clears.
2. If condition persists, execute PPE/LANBIC Receive Parity Error
Counter Test (# 597) and determine if the condition clears.
3. If condition persists, execute Packet Interface Test (# 598) to verify
circuit pack integrity.
4. If Packet Interface Test (# 598) fails, consult repair procedure for the
packet bus.
m. Error Type 2561-2668: System software received an indication that the
socket was closed due to an error. Errors are reported as log only. Errors
logged here are for the sockets that had no processor channels associated
with them, for example, sockets to read SNMP data. The counter base is
offset by the application type of the application associated with this socket
that is down. The Aux Data field of the log entry contains this application’s
number, for example, a SNMP application would have its application
number in the Aux Data field.
NOTE:
2561 - 2668 is a range of reserved numbers for future applications.
2570 currently represents an SNMP socket failure.
n. Error Type 2817-2819: Congestion Query Test (#600) failed.
The Error Types correspond to the descriptions:
1. Refer to Congestion Query Test (# 600) for Abort and Fail 3601s.
Error Type: Description
2305 Received invalid LAPD frame.
2306 Detected parity error on received frame.
2817 All buffers exhausted.
2819 Utilized buffers exceed threshold.
If: Then:
Active buffers exceed threshold, CLAN enters congested state.
