l. Error Type 2305-2306: Error in received frame from packet bus.
Error Type:
2305
2306
Most likely cause—packet bus problem.
Other cause—circuit pack fault.
Invalid LAPD frame errors occur when the frame

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.
n. Error Type 2817-2819: Congestion Query Test (#600) failed.

2561 - 2668 is a range of reserved numbers for future applications.
2570 currently represents an SNMP socket failure.
