Shelf Controller Firmware Requirements

Version 4.1.11 requires one or two (for redundant operation) ASCs or ASC2s. If two Shelf Controllers are in place, they must both be at Version 4.1.11 (The active shelf controller will overwrite the firmware on the standby controller).

Shelf Controller Backup Boot Firmware Requirements

Both ASC and ASC2 Controller models should use ASC_BT_1.0.03 as their backup boot image for proper operation.

Upgrade Procedure

Upgrades are supported from Version 2.X, Version 3.X, Version 4.0.x and Version 4.1.x. For upgrade procedures, reference the Version 4.1.X upgrade procedures document.

For manual upgrades using the revup command from the CLI prompt, it should be taken care that the revision name is not longer than 20 characters otherwise it will fail to rename the file. This issue is encountered only with the dated revision names, and not necessarily with the standard ones.

Additional Commands/Features

FRSM:

Additional Deliverables

There are no additional deliverables required for Release 4.1.11.

Features Not Supported

There are known issues with AUSM ILMI, in version 4.x. For ILMI support it is advised to upgrade the firmware to 5.0.16 and later versions.

Notes & Cautions

CESM-8T1 supports two kinds of models:

Model A: Supports Basic, SF and ESF connections on a structured port and basic connection on an unstructured port.

Model B: Supports Basic, SF, SF-MF, ESF and ESF-MF on a structured port and basic connection on an unstructured port.

How to Distinguish a Model B Card from a Model A Card

Use dspcd command, "Fab number" field contains the necessary information for Model B card.

Procedure for Graceful Replacement of a Model B Card with a Model A Card:


Step 1   Change all SF-MF connections on the line to SF connections using xcnfchan command.

Step 2   Change all ESF-MF connections on the line to ESF connections using xcnfchan command.

Step 3   Replace Model B card with Model A card.


Effect of Ungraceful Replacement of a Model B Card with a Model A Card

The Model A card does not support SF-MF and ESF-MF types of connections. All SF-MF and ESF-MF connections will automatically be changed to SF and ESF connections respectively. Though it does it automatically, it's "NOT advisable" to do so.

Procedure for Replacing a Model A Card with a Model B Card


Step 1   Replace Model A card with Model B card.

Step 2   Now on Model B card, if you want to change SF / ESF connections to SF-MF / ESF-MF connections on a particular line, use the xcnfchan command.

Such change will take effect for all the other channels on that particular line, so that there's no conflict of CAS type of different connections on same line.



Note   When CESM-8T1 Model B card is reset, when the card is in "BOOT" state, dspcds shows the card type as "?". This is a cosmetic problem as the card comes up fine and when it does, the display is correct.


Caution   ASC service modules with flash disk have a high probability of disk failure if a write to the disk is interrupted. Writes can be interrupted while resetting the card, removing the card and for other reasons. Therefore, it is absolutely necessary that the disk should be quiesced or downed before doing any operation that could interrupt a disk write. The 4.1.05 ASC and subsequent firmwares do an automatic quiesce or downdisk for most of the cases in which a write to the disk can be interrupted. There are some scenarios where the downdisk has to be manually executed and there are some cases where it is not possible to do downdisk. The following table lists the various possible scenarios when a disk write can be interrupted.


Table 3: Disk Write Interruption Scenarios
Scenarios Downdisk Operation Comment

Power Outage

Cannot be done

Flash disk is exposed to corruption if a write was being done at the time of power outage. Verify disk health after occurrence.

Manual Power Shutdown

Manual

Flash disk can be protected by doing a downdisk from CLI on Active and Standby ASC before power shutdown. Use option 1 in downdisk CLI.

ASC Removal

Manual

Flash disk can be protected by performing a downdisk on the ASC to be pulled out.

Watchdog timer reset

Cannot be done

Flash disk is exposed to corruption if a write was being done at the time of ASC reset. Verify disk health after occurrence.

ASC reset from CLI resetcd

Automatic

The firmware automatically shuts the disk before resetting the ASC.

Shelf reset from CLI resetsys

Automatic

The firmware automatically shuts the disk on both Active and Standby before resetsys.

clrallcnf CLI

Automatic

The firmware automatically shuts the disk on both Active and Standby after clearing the configuration and before resetting.

Shelf reset by task failure

Automatic

The firmware automatically shuts the disk before resetting the ASC.

ASC reset due to GRAM exception

Automatic

The firmware automatically shuts the disk before resetting the ASC.

ASC reset due to SAR exception

Automatic

The firmware automatically shuts the disk before resetting the ASC.

ASC reset because unknown reason

Cannot be done

The flash disk is exposed to corruption if a write was being done at the time of ASC reset. Verify disk health after occurrence.

For information on downdisk CLI to perform manual quiescence of the hard disk refer to the section on Additional Commands/Features.


Note   These procedures when applied to all types of hard disks in the ASC increases their reliability and hence it is highly recommended to follow these procedures for all the hard disks.

ASC/B cards with Calluna Hard disk are exposed to failures due to EMI when all of the following conditions are present:

The workaround for this problem is:

    1. not to have a service module in slot 5 or

    2. to use backcards for all the service modules on the shelf

This is problem is more frequent if the service module used in slot 5 is CESM8. The problem is also seen with FRSM4 in slot 5 but the frequency is considerably less. This problem is present in all previous AXIS firmware releases.

Limitations

The tstcon command cannot be used between IGX/BPX/MGX. This is because whenever a tstcon is used the SWSW tells the remote end to be in remote loopback. In the scenario SWSW in BPX cannot directly communicate to any service card in AXIS hence the loopback command is not sent to FRSM. Because of this limitation the tstcon payload will be processed as a normal data payload and hence will not loopback.

AUSM ILMI should not be turned on in version 4.x. There are known issues in this version.

clralm -sonet will not clear 15min alarms on the ASC.

CSCdt94979

BNM-155

Line Statistical Alarm on BNM-155 can not be cleared in clralmcnt.

Symptom:

Line Statistical Alarm which occurs on BNM-155 tried clralmcnt but can not clear alarm.

Conditions:

Line Statistical Alarm recorded on BNM

Workaround:

Go to shellConn. Issue IntegrateCardAlarm(0,2097,12)

Execute the switchcc command

Further Problem Description:

Line statistical alarm was not getting cleared because the 15min stats alarms remained. Clearing 15min alarms is a design change and would require a PER for the change to come to effect. CSCdu05641 carries the justification for the same.

A SONET equipment provides performance monitoring registers for the current 15-minute and one-day periods. Once a time period lapses, register counts are stored and a new register starts for the next time period. For historical purposes, the current 15-minute and day registers, as well as the last 32 15-minute registers and the last day register, are stored.

Each SONET network element provides a sliding window of performance history for each of its facilities. For long-term data storage and historical trend analysis, performance monitoring information can be reported to an operations support (OS) system or network manager. That's why the Current15min alarms are not cleared.

If clralm is issued 15 minutes after the line goes in statistical alarm, i.e. after the Current15min alarms have spilled over 15min bucket into the 24hr one, the alarms will be cleared and card will behave as expected.

Fix Description:

Since 15min alarms could not be cleared a patch is put in place which would clear the alarm state of the BNM-155 card. Nevertheless, because the 15min alarms are on, dspalm output would show them. Also, the MINOR LED on the card will glow as the aumUpdateAsmAlarms function will update the LED's. The fix is available in the 5.0.17 version as part of 5.0.17 bundle of images.

CSCdj68472

BNM-155

Problem of Alarm status of AXIS connected between BNM-155 and BXM-155

Symptom:

Difference of Alarm status between LED and CLI.

Workaround:

None. Fixed in 4.1.11

CSCds34620

CESM-8T1E1

CESM ports are not seen in connection manager intermittently

Symptom:

Sometimes, while adding a new connection, ports are not showing up in the selection window properly in spite of their being present in the database. For example if the database has 4 ports for a card and shelf, it shows up only two of them or it does not show any.

Conditions:

It is intermittent and highly random.

Workaround:

Hit Cancel button so that the new connection window disappears. And restart the configure new connection window from connection manager GUI.

Further Problem Description:

On the MGX side the problem is not seen if a physical (metallic) loopback is added instead of the soft loopback (through addlnloop).

CSCdu87342

CESM-8T1E1

Secondary card doesn't take over in 1:N redundancy when Primary is pulled out

Symptom:

The secondary card in 1:N redundancy doesn't cover the primary card if the primary card is physically removed.

Conditions:

Occurs when removing the primary card slowly

Workaround:

Use the softswitch command.

CSCdu88880

CESM-8T1E1

Violation of R2.3.1.1 in CES-IS 2.0

Symptom:

Analog modem calls which are transported over the Structured T1 CAS CESM connections may experience more bit corruptions than on a normal TDM link. This may even exceed the tolerable Signal to Noise Ratio(SNR) for some modems and might result in modem calls getting dropped.

Conditions:

The problem could be observed on Structured T1 CAS connections.

Workaround:

Use unstructured CESM connections if analog modems drop calls due to excessive bit corruption.

CSCdv20088

CESM-8T1E1

display of dspcd should distinguish between model A and model B cards

Symptom:

The display generated by running the dspcd command does not distinguish between model A and model B cards

Condition:

Always

Workaround:

None. Fixed in 4.1.11

CSCdv53811

CESM-8T1E1

Unable to snmpset cesmChanConditionedSigCode to a value other than 0

Symptom:

Using SNMP to set the "Conditional Signalling" field to any value other than 0 reports a SNMP general failure on a CESM PVC.

Also trying to use xcnfchan command fails to modify condsig value on an MGX8220 yet it works OK on an MGX 8250.

Conditions:

A CE-CE PVC is built using CWM. As CWM does not have a field to enter a Conditional Signalling value it gets set to 0.

Trying to use SNMP to set this to say 5 reports a general error:

aptcwm01% snmpset -c AXIS_SM_5 axis4-lan stratacom.110.5.3.2.1.1.1.26.32 INTEGER 5 snmpset: Agent reported an error. snmpset: SNMP: A general failure occured on the agent. aptcwm01% snmpset -c AXIS_SM_5 axis4-lan stratacom.110.5.3.2.1.1.1.2.32 INTEGER 3 stratacom.110.5.3.2.1.1.1.26.32 INTEGER 5 snmpset: Agent reported an error. snmpset: SNMP: A general failure occured on the agent. aptcwm01%

Workaround:

Delete and rebuild PVC via CLI and enter value manually.

Further Problem Description:

When using CAS signalling on a E1 line and you have a PVC added via CWM the Conditional Signalling code gets set to 0 automatically. This means that if there is an underrun the channel will send 0000 which causes the CPE equipment to drop the whole 2Meg line as it gets confused thinking there is a 2Meg line failure when it sees all zero's.

This problem of trying to use SNMPSET is only a problem on MGX8220 shelves. IT DOES NOT EXIST ON MGX8250 SHELVES. MGX8250 Allows SNMPSET successfully.

FRSM-8T1E1

FRSM-8 lines go into alarm if runslftstno 7 is used under bulk distribution

Symptom:

FRSM-8 card, running 5.0.12: Under Bulk distribution. When the "runslftstno 7" command is run, all lines go into alarm.

Conditions:

FRSM-8 card, running 5.0.12: Under Bulk distribution.

Workaround:

Check to see if card is under bulk distribution: Use the command "dspslotlink <slot>" on the active ASC. If under BULK distribution, then DO NOT use the "runslftstno 7" command on the FRSM-8 card.

If the problem has already occurred, a softswitch to the redundant FRSM-8 card resolves the problem.

FRSM-8T1E1

Statistics collection on FRSM card showing disabled

Symptoms:

Enabling statistics collection on FRSM connections fails if 6 different connection stats are already enabled.

Conditions:

Statistics Collection Flag is disabled if there are more than 6 parameters for which Statistics are being collected despite the fact that it is specifically being enabled through the enable file from CWM.

This has been seen on MGX 8220s running 5.0.12, 5.0.10, 4.x.x software.

Workaround:

The workaround is to reset the FRSM card which then allows as many different types of connection statistics to be enabled as required.

SRM-T1E1

Local Loopback didn't work on BERT test with E1 line configured as clear

Symptom:

While running a BERT test with a local loopback on a E1 line configured as Clear, the BERT test came back and gave some bits error count.

Conditions:

Workaround:

The workaround for this problem is to use a physical loopback plug and configure the BERT test as no local loopback. The test pattern will be sent out to the line and the pattern will come back as you have the loopback plug on. All test should pass with this test setup.
