Release Notes for VCLI Version 2.2.8.5
for Cisco MGX 8240

The Virtual Command Line Interface (VCLI) is a management application that runs on UNIX. It manages the MGX 8240 switches in the network. All 8240 features are supported from the VCLI. The VCLI is independent of all other management applications that Cisco provides.

VCLI Software Release 2.2.8.5 has all the functionality of the previous VCLI software releases. The last official release of the VCLI was Release 2.1.3. There is a beta release of VCLI software that was named version 2.2.8. Two major items new to this release are support for the new IMC card in the
MGX 8240 switch, and the functionality of the background polling task has been significantly enhanced. There have also been bug fixes to the previous 2.1.3 Release.

Release 2.2.8.5 fixes problems in the area of SW upgrade for the IMC cards. Those problems are described below in the list of Caveats.

Hardware Supported

All released hardware components of the MGX 8240 are supported. This release of the VCLI will manage an Cisco MGX 8240 switch with or without an IMC card. If the Cisco MGX 8240 is still connected to a CIM, the VCLI will not have a problem managing the CES cards.

Software Compatibility

There are no compatibility problems between this VCLI release and previous ones. This release should replace all earlier releases.

This version of the VCLI is also backward compatible, in that it supports all CES and IMC card software versions at or below 2.2.X. The software versions of the CES cards can be mixed in a chassis, and still be supported by the VCLI. The VCLI continues to support the In-Band or Out-Of-Band IP management route discovery for the CES cards. When the In-Band route is up and operational, In-Band management continues to be the preferred route of all management traffic between the VCLI and the CES cards.

Upgrading to a New Software Release

The VCLI software is distributed on the VCLI CD and contains three files listed below. The files that have the `.tar.Z'suffix are compressed UNIX archive files. These files are uncompressed using the UNIX "uncompress <filename>" command, and un-archived using the "tar xvf <filename>" command.

New and Changed Information

This release builds upon all other features of the VCLI. No features that existed in previous releases of the VCLI have been removed. Please consult previous release notes and user guide documentation for the list of features

The features in VCLI version 2.1.3 are described below, and the descriptions apply to the features of all releases since the last major VCLI release, which was 2.0.X.

New in version 2.1.3 of the VCLI is support for both CES card hardware types. The only two types of CES cards that this version of the VCLI will support are

1. The original CES card type that supports the original I/O card with 3 channelized DS3s, and two OC3 ports.

2. The new CES (called the CS3) card type which can support the original I/O card type, as well as the new I/O card type with 4 OC3 ports (the DS3 ports are contained within the OC3 port).

New Software Features in Release 2.2.8.5

This release includes two new developments: support for the IMC card in the Cisco MGX 8240 switch, and significant enhancement to the background polling task functionality. There have also been caveats resolved since the last release.

The IMC card is the management card in the chassis, and compared to the CES cards has very few features to be managed. The VCLI supports the IMC redundancy feature, the MIB II system group table, and software upgrade. The IMC card cannot be managed in-band in Release 2.2.X of the Cisco
MGX 8240 switch software. The IMC card replaces the CIM product that was shipped with all Cisco MGX 8240 switches.

New VCLI commands were added to support the IMC, including:

VCLI>> show imccard info

VCLI>> show imccard config

VCLI>> change imccard config

VCLI>> show imccard redundancy

VCLI>> change imccard redundancy

VCLI>> change imccard image

The background polling feature is referred to as BladeMonitor. In previous releases, background polling was done as part of the VCLI task process. Starting with this release, the VCLI will spawn a BladeMonitor sub-process. As a separate process, one BladeMonitor process will support all VCLI sessions that are started. The BladeMonitor process will continue to poll all cards and switches in the network while at least one VCLI session is active. The BladeMonitor process terminates itself after a few seconds when it detects all VCLI processes have been terminated. New features for the BladeMonitor are more efficient network polling, the ability to see how the BladeMonitor is interpreting network connectivity, and the BladeMonitor's own performance statistics.

New VCLI commands that were added to support the BladeMonitor include the following:

VCLI>> show blademon statistics

VCLI>> show blademon information

New Software Features in Release 2.1.3

The features in VCLI Release 2.1.3 described here still apply. These descriptions remain as part of the VCLI 2.2.8.5 Release Notes because they still apply to all the new features since the last major VCLI release, which was 2.0.X.

New in Release 2.1.3 of the VCLI was support for both CES card hardware types. The two types of CES cards that Release 2.1.3 of the VCLI will support are

1. The original CES card type that supports the original I/O card with 3 channelized DS3s, and two OC3 ports.

2. The new CES (called the CS3) card type which can support the original I/O card type, as well as the new I/O card type with 4 OC3 ports (the DS3 ports are contained within the OC3 port).

Compatibility

This release of the VCLI is backward compatible; it supports all CES and IMC card software releases at or below 2.2.X. The software releases of the CES cards can be mixed in a chassis, and still be supported by the VCLI. The VCLI continues to support the in-band or out-of-band IP management route discovery for the CES cards. When the in-bandroute is up and operational, in-bandmanagement continues to be the preferred route of all management traffic between the VCLI and the CES cards.

Caveats

These are known caveats for this release of the VCLI. Some of these problems are covered by DDTSs, defined in the tables below.

The VCLI allows users to change the redundancy role of primary card to a role of "none', the primary card is being forced back into service. The VCLI should not allow this change while the card is in this redundancy state. Changing the redundancy role of the primary card while in this state could cause a problem with the configuration database of the primary card. The DDTS number for this problem is CSCdm71570. There is no work-around for this problem.

The VCLI has a problem with a switched-out primary card when the primary card is not responding to SNMP PDUs. The VCLI should divert all user queries to the switched-in backup card. But instead the VCLI reports that it cannot communicate with the switched out-primary. This is most likely to occur when the primary card is pulled out of the switch. The DDTS number for this problem is CSCdp39816. The work-around for this is to explicitly specify the switched in backup card for all VCLI queries.

There is a problem for the VCLI creating Private Line circuits between two CES cards in two different switches when one card is running Release 1.1.2.10, and the other is running Release 2.X. The order of how the two endpoints are specified is important. When creating a circuit with the described scenario, the user must specify the Release 1.x version as endpoint 1. There is no problem if the two endpoints are on the same switch. DDTS CSCdp35740 identifies this problem.

To accommodate two card types in the same switch chassis, the switch software upgrade procedure was changed from previous releases of the VCLI. Previous versions of the VCLI updated the CPE card Software only. This version upgrades the Software for both IMC and CPE card types. This requires that the contents of the Tar files, which contain the Software upgrades, have a new directory format. VCLI version 2.2.8.5 cannot use a Tar file built with the old directory format. All CPE and IMC card Software upgrade Tar files, beginning with Release 2.2.0.3 (and higher) of the CPE and 2.2.0.11 (and higher) of the IMC, have this new format.

In this release of the VCLI, the background polling process is a separate task from the VCLI process. The background polling process is called the BladeMon. The BladeMon process updates a file called "blade.db." All VCLI processes read this file to get switch and blade connection information (e.g. whether to use the InBand or OutOfBand interface to a CPE card). The BladeMon process can die. It doesn't happen unless it was explicity terminated, or there was a UNIX related system problem. When BladeMon dies, the VCLI processes can't detect that it has died if the file "blade.db" remains. The VCLI processes continue to operate as before using whatever old information is in the "blade.db" file. This can remain for days, and not cause a problem. The symptom that is most common when this scenario occurs is that network additions/deletions or redundancy changes will not be reflected in the VCLI. The VCLI will continue to read the information that was present in the "blade.db" file when the BladeMon process died. This condition can be verified by using the VCLI command show blademon stat. The statistic that counts the number of polls will not increment when the BladeMon process has died. DDTS CSCdm30982 chronicles this defect.

Fixing the above problem is easy. When the problem occurs, the ".blade.pid" file must be manually removed using the UNIX command rm .blade.pid, and a VCLI restarted. When the VCLI restarts, it will restart the BladeMon process, which will read the VCLI switch database. Upon startup, the BladeMon will query all CPE and IMC cards in the network to quickly rebuild the "blade.db" file with fresh information. This should take only a few seconds. Old VCLI processes need not be terminated while this is going on. However, if they are terminated it's not a problem.

Resolved Caveats—Release 2.2.8.5

	VCLI 2.2.8.5
DDTS Number	Severity	Functional Area	Problem Description
CSCdp72170	High	SW Upgrade	The VCLI continues to proceed with a CES and IMC SW upgrade even though a crucial file "contents" is not found in the directory containing the new SW images. Now, if that file is not found, the VCLI stops the upgrade.
CSCdp72169	High	Blade Monitor	The Blade Monitor process stops polling the network. This fix was to change the UNIX function call used to pause the Blade Monitor process.

Open Caveats—Release 2.2.8.5

	VCLI 2.2.8.5
DDTS Number	Severity	Functional Area	Problem Description	Comments
CSCdp39816	High	Redundancy	Unable to communicate to switched-out primary and switched-in backup when the primary card is not responding to SNMP PDUs.
CSCdm73811	High	Connection creation	Cannot make connection between CES cards running different SW versions.	This wasn't a defect. Release 1 CPE SW can't handle EPIDs as large as Rel 2 SW.
CSCdp35740	Medium	Connection creation	VCLI cannot create a PL circuit from a CES card running Rel 2.x SW to card on a different switch running Rel 1.x SW.
CSCdm90826	High	OC3 status	The SONET path operational status of the access side as reported by the VCLI can be incorrect if the access OC3 port is APS protection switched to the protection line.	Should be fine if APS is not enabled or the working line is active.
CSCdm71570	High	Redundancy	VCLI allows configuration changes to CES cards while their redundancy state is FBP (Force Back in Progress).	See note in "Caveats," above.
CSCsn05508	Medium	APS	VCLI displays an error if def card is invalid for command change cescard aps?	Only occurs when help requested
CSCdp40572	Medium	SONET Path Thresholds	VCLI cannot change the Error thresholds values for the SONET Path level on the Channelized Access OC3 ports.
CSCdp34882	Medium	Ckt BERT	VCLI cannot set the transmit and receive bit inversion attributes for PL and SegPL type circuit BERT tests. These attributes apply only to User data pattern configured BERT tests.
CSCdp35483	Medium	IMC	The command show imc info doesn't check if backup IMC is present in the switch. Consequently, if the backup card is not present, the command takes several seconds to complete.
CSCdp35469	Medium	IMC	The VCLI doesn't report the SW version of the backup IMC card from backup IMC. It displays the SW Version of the Primary card for the backup too.
CSCsn05671	Low	Performance	Request to increase VCLI performance when creating a pl type connection	Not a bug; it's just slow.
CSCdm70079	New feature	Show connections	Add feature to show what the default physical ports are when listing the connections on a card	Feature request
CSCsn05455	Low	Show cmds	Some show commands don't recognize that the user has entered invalid options. The VCLI ignores these options because they are not needed rather than tell the user that they gave options that are illegal.
CSCsn04479	New feature	usability	Curses doesn't work—need real terminal mode for line editing. An enhancement will allow true cursor controlled line edits.
CSCsn04947	New feature	Config files	Enhancements: Add capability to backup and restore config files.
CSCsn04974	New feature	Sw upgrade	Download related code should display info about user, time downloaded, downloaded from, etc., for record keeping.
CSCsn05072	Low	Switch database	For -network 1 options it would be nice if switch names are alphabetically ordered.
CSCsn05073	New feature	Trap handling	Need to integrate VCLI's trap handling with redundancy related code. This way VCLI knows when to switch between in-band and out-of-band.
CSCsn05492	New feature	Ces card info	VCLI's "sh ces inf" should display both SW as well as FW active and inactive releases so a user knows what s/he is switching to.
CSCdm30982	Medium	Background polling	When BladeMon process dies, the redundancy status of the Cisco MGX 8240 cards in the network gets stale without the VCLI being aware of it.	The fix is to remove the file `blade.pid' and restart a VCLI.
CSCsn05494	Low	CES card addition	If two or more users make changes database changes to the VCLI database (e.g. add/delete cards, add/delete switches), then changes can be overwritten in the VCLI database.	A single user should make all changes to the database.
CSCdp28944	High	SW upgrade	VCLI download command doesn't check for file types when downloading files to Cisco MGX 8240 card. It blindly FTPs files that are found in the directories specified by the value of the `imagedir' attribute.	This problem should not occur if the upgrade procedures are followed.
CSCdp37110	Low	Connection creation	The VCLI will create a local PL type connection without having the second endpoint specified on the command line. Both endpoints should be specified on the command line for any type of PL circuit.
CSCdp08025	Medium	Redundancy	When the CES software has a I/O card incompatibility problem, the CES card reports a redundancy role value of "3." This is not a legal value according to the SNMP definition of the redundancy Role. When the CPE card returns this value, the VCLI displays a `-' for role.	When the I/O card is incompatible, this is a serious CPE problem, and the VCLI display of a `-'is minor in comparison.
CSCdp37110	Low	Connection creation	The VCLI creates a local PL type connection without having the second endpoint specified on the command line. Both endpoints should be specified on the command line for any type of PL circuit.
CSCdp40302	Low	Output display	The q to quit command to cease the output of data to the screen doesn't work the first time for the command show physical oc3 stat.
CSCdp23296	Low	Chassis cmd	When a Chassis level command is given on the VCLI, the VCLI will only go so far before prompting user Hit Return to Continue, q and return to quit. For chassis commands, the VCLI should not stop to query user.
CSCsn05714	Low	Change cmd	When a required command line argument is not given, the VCLI should display the argument that is missing, not a generic message stating such.
CSCdm88355	Medium	BERT	The VCLI doesn't display any digits after the decimal point for the attribute PercentErrorFreeSeconds when viewing BERT Status for DS1 or Circuit BERT tests.
CSCdp33107	Low	Download Help	Help for the command `download -card?' doesn't inform user that IMC is card 1, and CPE are cards 2-16.
CSCdp33137	Low	Download cmd	In the download cmd, the VCLI doesn't give an informative error message, when the cardtype argument doesn't match the slot of the card.

Resolved Caveats—Release 2.2.8.4

	VCLI 2.2.8.4
DDTS Number	Severity	Functional Area	Problem Description
CSCdp36225	High	Ascend provisioning	The stored ascend uplink string was truncated if the Cisco MGX 8240 slot was greater than 9. This caused the ascend provisioning server to fail to create the ATM connection in the ascend cloud.
CSCdp38898	High	BladeMon	Illegal characters in a switch name cause the BladeMonitor to cease working properly. The VCLI now checks for legal characters in switch name when users add new switches to the VCLI database.
CSCdp38890	Medium	BladeMon	BladeMonitor was reporting the OutOfBand link to be down when the in-bandLink was up. The OutOfBand link status should be reported regardless of the in-bandlink state.
CSCdp38871	Medium	BladeMon	The command show blademon info displayed the in-bandcommunication state to a card down twice if the OutOfBand and in-bandlink were down

Resolved Caveats—Release 2.2.8.2

	VCLI 2.2.8.2
DDTS Number	Severity	Functional Area	Problem Description
CSCdp33196	High	IMC SW upgrade	The VCLI isn't waiting long enough for the IMC redundancy situation to settle after the backup IMC has rebooted, and is ready to become primary. The VCLI is proceeding with the upgrade of the second IMC too soon.
CSCdp02650	Medium	IMC redundancy	If the IMC card with a Cisco MGX 8240 chassis is not available for IP communication, then the VCLI command `show switch redundancy' shows that it is. All other IMC commands fail.
CSCdp33191	High	IMC SW upgrade	When the VCLI initiates the upgrade on the backup IMC, if the backup IMC returns an error to the SNMP_SET request, the VCLI didn't cease the upgrade, and continued on with by attempting to upgrade the other IMC card in the chassis.

Resolved Caveats—Release 2.2.8.1

	VCLI 2.2.8.1
DDTS Number	Severity	Functional Area	Problem Description	Comment
CSCdp02650	Medium	IMC redundancy	If the IMC card with a Cisco MGX 8240 chassis is not available for IP communication, then the VCLI command show switch redundancy shows that it is. All other IMC commands fail.
CSCdp00218	Low	CES redundancy	In show switch redundancy command, VCLI does not differentiate between configured cards that cannot be communicated with and empty slots when it cannot communicate to these cards. The VCLI will show a `-' in both these cases. It should display `unknown' for configured cards.
CSCdm73051	Medium	Connection deletion	VCLI does not delete far end endpoint of a pl type connection, when only the near end endpoint of the connection is given. But the converse is not true: both endpoints will be deleted if the farend endpoint is given on the command line	Work Around was to delete farend, or to delete both endpoints separately.
CSCdp01075	Low	CES card addition	When a CES card is added to a switch, and that card already exists, the VCLI returns an uninformative error message.
CSCdm73801	High, Status is Closed	M13 IP address	Cmd `change system cescard -m13?ip 0' doesn't work.	This was never a bug. Changing IP addresses requires a few seconds for the CPE card to make the change visible to the VCLI. Setting `0.0.0.0' always works.
CSCdp00556	Low	PL ckt config	The loopback state of a PL type circuit is not shown anywhere in the VCLI. This state should be displayed in the output of the command show conn pl config.

Resolved Caveats—Release 2.2.8

	VCLI 2.2.8
DDTS Number	Severity	Functional Area	Problem Description
CSCsn05808	Medium	Show conn	VCLI used to display the incorrect circuit type on a backup CES card with the command show conn all sum when a backup was switched in for a primary.
CSCdm73146	Medium	Change BERT	User was unable to tell a circuit that was currently running a bert test to invert the transmit pattern. The command was "change connection segpl -txpattinv on -epid <endPointid>"
CSCdm77694	High	Show CES info	In Release 2.1.X of the VCLI, it didn't read the manufacturing related information attributes correctly for CES cards for the command show cescard info.
CSCdm77832	High	ATM Port stats	VCLI returned error when trying to retrieve the stats for the command show logicalport atm stat.
CSCdm77686	Medium	Show phy ds1	The row label for DS1 Frame errors didn't say that Frame Errors are measured as any second that contained a frame error. Instead it led the user to believe that the count displayed was the actual number of frame errors.
CSCsn05790	High	Redundancy	In certain situations the VCLI used to give an error when the user attempted to put a CES card in the primary role from a role of None. A second attempt seemed to work.
CSCdm75085	High	Show OC3 sum	VCLI shows the operational state of the SONET Path layer on the Access OC3 to be up when either the SONET Section, SONET Line Layers are operational down.
CSCdm82392	Medium	Change sys switch	Using the command "change system switch -sname <new_name>" didn't update the VCLI database files.
CSCsn05541	Medium	BladeMon	VCLI takes a long time to establish communication with CES card after the card reboots. Now it communicates within seconds after the CES card is available for communication.
CSCsn05684	Medium	BladeMon	Duplicate problem of CSCsn05541.
CSCsn05781	Low	BladeMon	Exit and restart of VCLI causes delay in communicating with the CES cards in the network. Now the BladeMon process keeps in contact for the VCLI.
CSCsn05736	Low	BladeMon	Need to make BladeMonitor a stand alone application.
