Limitations and Restrictions

This section describes limitations and restrictions that are associated with the MWTM.

Provisioning Timeout

When using the MWTM provisioning feature to modify the management interface, sometimes the operation fails with this message:
No prompt response
This response can occur when changing the duplex or speed attributes for the Ethernet interface. The response can also occur for other interface attributes that affect IP connectivity between the MWTM and the device.

The default setting for a provisioning operation timeout is 50 seconds. As a workaround, the system administrator can increase the TGS_OP_TIMEOUT attribute in the System.properties file to a higher value. You must restart the MWTM server for this change to take effect.

SSH-enabled Nodes

The MWTM Node > Home Page right-click menu option does not work correctly for the following SSH-enabled IP Transfer Point (ITP) nodes:

•Cisco 2600

•Cisco 7200

•Cisco 7300

•Cisco 7500

•Cisco 7600

The browser launches, as expected, but the user is not prompted for login information.

Note This limitation exists for any ITP node running the 12.2(x) IOS with SSH enabled.

MWTM Telnet Proxy

If you enable the MWTM Telnet proxy (mwtm tnproxy enable command), you cannot use an external Telnet program to connect to a node from the MWTM client; you must use the Telnet program that comes with the MWTM.

To use an external Telnet program, you must disable the MWTM Telnet proxy (mwtm tnproxy disable command).

Open MWTM Caveats

This section describes caveats that exist in the MWTM 6.0 software:

•CSCsc88099

Symptom    If a command with INSTANCE_NUMBER is included in the UserCommands.ts file, the instance number will appear on all nodes in the GUI. If you run this command on a node that does not have multi-instance enabled, it fails.
Workaround   If you have a network with both single and multi-instance nodes, you must configure a separate set of troubleshooting commands for each node type in the UserCommands.ts file. Do this by grouping the commands for each type under a separate category.

•CSCsg83861

Symptom    The preferences dialog of the MWTM client interface allows you to customize the way that data series appear in charts. You can specify series color, line style, and symbol style. However, symbol style and line style preferences do not work when displaying real-time charts for MSU rates and for RAN backhauls and shorthauls.
Workaround   None

•CSCsh00145

Symptom    Credentials for a node are associated with a unique IP address. If a node has more than one accessible IP address, functions that require credentials might not resolve to a credential based on the selected IP address, and the requested function would fail. The MWTM functions that require credentials include:
•Discovery of ONS and RAN_SVC nodes

•Troubleshooting

•Provisioning

•Route and Global Title Translation (GTT) table deployment

Conditions   Nodes with multiple, accessible IP addresses with credentials set for a subset of those IP addresses.

Workaround   Specify credentials for all accessible IP addresses for a node.

•CSCse81393

Symptom    In various GUI and web pages, simple text fields might contain unprintable characters. An example is the Model Name PID field for a RAN service (RAN_SVC) card in an ONS chassis.
Conditions   Some RAN_SVC cards in an ONS chassis can exhibit this behavior.

Workaround   None. This is a cosmetic problem and does not affect functionality.

•CSCsh15638

Symptom    The following exception with corresponding stacktrace can occur. The MWTM captures this exception in the sgmConsoleLog.txt file:
java.net.SocketException: Broken pipe
Conditions   This exception can occur when users access the MWTM web interface and frequently abort connections while the server is under heavy load (for example, during discovery). Pressing the Stop button on the web browser or navigating to a different web page before the current page finishes loading can cause this exception to occur.

Note The root cause of this condition is an internal bug in the Tomcat web application that ships with this release of the MWTM.

Workaround   None, but you can safely avoid these log messages.

•CSCsh58070

Symptom    The following error messages may appear when performing these operations:
Operation

Error Message
Generating link report by using the sgmLinkStats.sh script
sgmgawk: cmd. line:45: (FILENAME=- FNR=???) 
fatal: division by zero
Attempting to import link and linkset report data
ERROR 38000: The exception 
'java.sql.SQLException: Invalid character 
string format for type SMALLINT.' was thrown 
while evaluating an expression.
Using the ITP route table deployment function
Invalid Linkset in Route Table: [???]
Conditions   The error messages occur when ITP linkset, AS, and ASP names contain a colon [:].

Workaround   Remove the colon [:] from ITP linkset, AS, and ASP names.

•CSCsg92892

Symptom    When provisioning ITP nodes from the Provision tab of the web interface, some provisioning operations might fail on the node with these symptoms and conditions:
Provisioning Action

Symptom

Condition
Changing the media type for FastEthernet or GigabitEthernet interface
Invalid input 
detected
FastEthernet or GigabitEthernet on the node does not support the media type configuration option, but the user specified a media type in the MWTM provisioning request.
Changing speed for FastEthernet or GigabitEthernet interface
invalid input 
detected
FastEthernet or GigabitEthernet on the node does not support the speed configuration option, but the user specified the speed in the MWTM provision request.
Configuring MTP3 User Adaptation (M3UA) or SCCP User Adaptation (SUA) offload, or Local Peer offload
Error: at least one 
address must reside 
on slot xx
The user specified an IP address that does not exist for the specified card slot
Configuring M3UA or SUA offload, or Local Peer offload
Error: XXX is 
already offloaded 
to this linecard 
slot=xx
The user specified a target card slot that is already in use by another M3UA or SUA offload, or Local Peer offload.

Note The ITP does not allow mixed types between M3UA or SUA offload, and Local Peer offload.
Configuring the line priority for the clock source line option on the Cisco 2600 T1/E1 controller
% Invalid input 
detected at '^' 
marker.
The '^' marker points to the line priority: primary or secondary.
While configuring the clock source line priority option on the T1/E1 controller, the user specified the primary or secondary option on the line, but the WAN Interface Card (WIC) card has only one port, and does not support the line priority option.
Configuring the secondary line priority for the clock source line option on the Cisco 7xxx ITP T1/E1 controller
% Invalid input 
detected at '^' 
marker.
The '^' marker points to the secondary line priority: primary or secondary.
When configuring the clock source secondary line priority option on the T1/E1 controller, the user specified a number that is greater than the supported range on the device. Although the MWTM allows values 1-72, some cards only support 1-8 or 1-16.
Workaround   None. The user must know the ITP card information and specify correct values in the provisioning request.

•CSCef67144

Symptom    Sometimes when using the client on a Solaris multi-processor computer, an exception occurs when the topology window is open and you are manipulating views.
Workaround   Close the topology window, then reopen it.

•CSCsg62928

Symptom    The RAN-O backhaul performance charts can show incorrect % Utilization (Y axis, on the right side of the chart).
Conditions   RAN-O backhaul interfaces with asymmetric link speeds or different physical interfaces for send and receive traffic. For example, you might observe this symptom if the backhaul uses Digital Subscriber Line (DSL) or cable media.

Workaround   Use the Y axis on the left side of the chart, which shows backhaul utilization in bits or bytes per second.

•CSCsh89439

Symptom    Loading the GTT table from an ITP might fail with this error message:
nameFormatErr
Conditions   The ITP network name contains a space (  ) character.

Workaround   Remove the space (  ) character from the ITP network name, or use an underscore (_) or a hyphen (-) instead of the space (  ).

•CSCsh89933

Symptom    When you select a shorthaul in the navigation tree of the MWTM web interface, and click the Errors tab, the total number of errors displayed might not equal the sum of the individual errors because of rounding errors. The total number of errors might be one or two counts more or less than the sum of the individual errors.
Conditions   You have enabled RAN-O statistics collection.

Workaround   None. These minor mismatches will cancel each other over a few adjacent report intervals. The mismatches do not accumulate over a period of time.

Open Device Caveats

This section documents caveats associated with the devices that the MWTM manages. These caveats can affect the capability of the MWTM to manage the associated features. Follow the guidelines in the workarounds for these defects.

•CSCsg76526

Symptom    When you unconfigure Preventive Cyclic Retransmission (PCR) from an MTP2 link on an ITP device, the device incorrectly retains tuning parameters, such as n1 and n2, in the running configuration.
Conditions   You configure PCR and set tuning parameters with values other than default values.

Workaround   Unconfigure the tuned parameter first. Then unconfigure PCR.

•CSCsg77134

Symptom    When you unconfigure a tuned parameter for a link that belongs to a linkset with a configured profile, the default value for the timer is incorrectly restored instead of the profile timer value.
Conditions   The cs7 profile is overriding the profile value.

Workaround   Unconfigure and reconfigure the profile for the linkset. This action should restore the profile value to all links.

•CSCsg77152

Symptom    When you configure the following parameter for an SCTP link:
 retransmit-cwnd-rate <rate> sctp-fast-retransmit
the sctp-fast-retransmit portion is not saved in the configuration, and is ignored at the next reload.

Conditions   Tune the sctp-fast-retransmit parameter for retransmit-cwnd-rate.

Workaround   Reconfigure the parameter after reloading the device.

•CSCsh71843

Symptom    The Management Information Base (MIB) ifTable does not contain T1/E1 controllers for the T1/E1 controllers on the Cisco 2600 WIC card.
Conditions   The Cisco 2600 with a T1 or E1 WIC card running IOS 12.4(11)SW.

Workaround   None. You cannot use the MWTM to:

•Show T1/E1 controllers on the Cisco 2600 running IOS 12.4(11)SW.

•Provision T1/E1 controllers or channelized serial interfaces on the Cisco 2600 running IOS 12.4(11)SW.

•CSCsh13017

Symptom    The MWTM login credentials might not work if you run the no enable secret command on the active RAN Service (RAN SVC) Module.
Conditions   During failover, the running configuration on the active RAN service card merges with the RAN protection card. As a result, any baseline configuration command that exists on the protection card but not on the active card will be applied.

Workaround   For all RAN service cards:

•Apply the enable-secret configuration option.

•Define these credentials in the MWTM.

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—An existing network is down, or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of the network is impaired, while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
