CLAN-BD (Control LAN Circuit Pack)
Issue 1 June 2005 795
3. Reset circuit pack with the busyout board location, reset board location,
and release board location commands.
4. Clear alarms using the test board long clear command.
5. If the error returns within 15 minutes, replace the circuit pack.
k. Error Type 1797: Invalid layer 2 frame received.
l. Error Type 1798: Unable to write translation RAM.
1. Attempt to clear alarm with reset board location.
2. If alarm recurs within 15 minutes, replace the circuit pack.
m. Error Type 2049: Packet Interface test (#598) failed.
1. Attempt to clear the alarm (test board location l r 3).
2. If alarm does not clear, reset the circuit pack with reset board location.
3. If circuit pack resets, execute Packet Interface test (#598) several times.
4. If Packet Interface test (#598) continues to fail, replace the circuit pack.
n. Error Type 2305-2306: Error in received frame from packet bus.
This may be due to a packet-bus problem or 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 test board location and see if the condition clears.
2. If condition persists, execute PPE/LANBIC Receive Parity Error Counter test (#597), and
determine whether 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.
o. 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.
Error Type Description
2305 Received invalid LAPD frame.
2306 Detected parity error on received frame.
