PKT-INT (Packet Interface)
Issue 1 June 2005 1821
Private Loop-around Tests (#885)
This test requests the Packet Interface to execute its two private loop-around tests: Level-2
Loop Around, and Broadcast Path Loop Around. These tests verify the health of the circuit
pack’s packet-bus interface, as well as the translation RAM, inward and outward bound data
paths, parity indications and CRC calculations.
● Level-2 (LAPD) Link Loop Around
LAPD is a link-level protocol that is used for all system links. This test verifies the health of
the processing of these links.
2 FAIL The Flash memory checksum test failed. The circuit pack may still be
operational, but will fail if a reset is executed.
1. This may be the result of old firmware not supporting new software
operation. Verify the IPSI circuit pack’s firmware vintage and download
the new firmware if appropriate.
2. The firmware image on the IPSI circuit pack may have been corrupted.
Download the firmware image.
3. Retry the command.
4. If the same error occurs:
a. If this is a standard- or duplex-reliability system, replace the circuit
pack at a time that would cause the least disruption of service. The
circuit pack is still functional but should be replaced since it may not
operate after a system reboot and it will enter a fatal fault state if it is
reset for other reasons.
b. If the Packet Interface module is on the standby IPSI (
S8700 MC: and
this is a high- or critical-reliability system), replace that circuit pack.
c. If the Packet Interface module is on the active IPSI (
S8700 MC: and
this is a high- or critical-reliability system), use set
ipserver-interface to perform a planned IPSI interchange.
3 FAIL The Boot PROM memory Checksum test and the Flash memory checksum
test have both failed. Follow the steps listed for FAIL Error Codes 1 and 2.
PASS The circuit pack’s firmware is in a proper state. If problems are still reported
on the circuit pack, check for errors on the Private Loop-around test (#885)
and Maintenance Loop-Around test (#886).
