Release Notes for Cisco MGX 8850 (PXM45), MGX 8850 (PXM1E), and MGX 8830, Software Release 3.0.10
78
Severity 2 Open Caveats for MGX 8850 3.0.10 Software (continued)
Description
Hardware: pxm45b
Symptom: All AXSMEs failed in the shelf due to Max Card Reset reached.
Conditions: Due to PXM45B resetting in slot #7 for no known reason.
Workaround: None.
Hardware: pxm1
Symptom: tstpndelay does not work
Conditions: When tstpndelay is issued for a SVC endpoint
Workaround: None.
Hardware: axsm1b_oc3
Symptom: By doing setrev/resetcd for both the cards, active card on the remote gets
reset.
Conditions: Having all the lines configured for APS. This is applicable only for OC3.
Description. This is fixed, however after doing the testing of our fix we have found
that, if all the lines are unidirectional then problem does not exist. If the lines have
bidirectional APS and in particular if the last line i.e. 2.8 is configured for APS then
the problem persists. If we have 15 APS lines irrespective of Uni/Bi then our fix
works. Only problem we have with the last line with bidirectional APS on other lines.
Workaround: Unknown.
Hardware: pxm45b
Symptom: Standby PXM went to empty state as seen in dspcds or dspcd.
Conditions: None.
Workaround: Issue resetcd on the standby PXM.
Hardware: pxm1e
Symptom: CBC clocking affected on active and standby PXM1Es does not switch
over to standby.
Conditions: Fault was inserted on standby card 8 and it is never detected by the active
card. Upon forced switch over, the standby did not take over and all the SM's were
reset and never came back up. If you insert a card with CBC clocking affected in the
standby slot, it is not detected. In this situation we may have a faulty standby card just
sitting in the node.
Workaround: Unknown.
Hardware: pxm1e
Symptom: FI: ATMizer SAR SDRAM data bus corruption & ATMizerII SAR chip
disable on active - does not switch over to standby
Conditions: FI: ATMizer SAR SDRAM data bus corruption & ATMizerII SAR chip
disable on active - does not switch over to standby. Both cards in ready state. When
fault inserted on active it does not switch over to standby. All PNNI links go down,
connections in fail state. Data traffic stops. Standby card resets after some time.
Workaround: Unknown.
