Cisco MGX 8800 Series Switches

CSCdk72991

Symptom:

FRSM-VHS takes several minutes to go active when inserted the first time or after clrallcnf.

Condition:

The delay is due to the creation time of the FRSM-VHS database on the disk. This delay is only introduced the first time the card is inserted or after clrallcnf.

Work around:

Wait for card to go active. The Hot Standby Feature has been introduced for VHS to mitigate this problem. With a hot standby the switchover happens in less than one second.

CSCdm89192

Symptom:

Oscillation of APS lines on switchcc.

CSCdm35462

Symptom:

Symptom:

CSCdm49706

Symptom:

CSCdp16642

Symptom:

dspln -ds3 command does not work for SRMs in 1.1.11Jd

Conditions:

When the PXM firmware is of a version later than 1.1.11Ja and the PXM back card is not a T3 back card.

Workaround:

Issue the command dsplns -ds3 <slotno> to get the required information.

Further Problem Description:

The problem occurs because of an invalid conditional checking during the display.

CSCdm45533

Symptom:

Round trip delay test results do not change on changing CDVT for CE-CE connection

Conditions:

1 While adding a connection, the aal1driver added the connection with default CDVT of 1000us. After adding the connection, the CDVT was configured. This effect of CDVT change was felt only after a channel failure

2 When modifying CDVT with cnfcon too, the same problem was found, because of the CBR traffic, the buffer size cannot be changed dynamically without dropping data, hence it was not possible to see the effect of change in CDVT immediately.

Workaround:

1 The first problem can be overcome by using CWM or the xcnfchan command to add a connection with value of CDVT different from the default

2 For dynamic changes in round trip as a result of CDVT changes, a shellConn command is introduced to synchronize the SAR queues. This command would, however, cause a momentary traffic disruption for CDVT to take effect

CSCdm33419

The Connection GUI misreports connection modification in the following scenario: 1. Add a 3-segment connection with PXM UNI endpoints. 2. Modify the SCR on the PXM UNI side to a big number, big enough to exceed the available bandwidth on the feeder trunk side. Also turn on CAC override. 3. Execute the modification. CWM will display a successful result, even though the modification is actually rejected because oversubscription is not allowed on the feeder trunk side.

CSCdm36595

However, in this release, this is now changed to physical slot numbering, rather than logical slots.
