What Is New In the Multicast Smart Plug-in 2.1
********************************************************
For complete information about migration, see the Multicast Smart Plug-in Administrator's Guide, Appendix E.
Changes from NNM Multicast 2.0 to NNM Multicast 2.0 with the Consolidated Patch
NOTE: The consolidated patch number is as follows:
Cisco's new router IOS versions support the IGMP MIB in the standard MIB-II branch.
The consolidated patch allows management of routers running IOS versions 12.2(4)T and later, as well as, the already supported older versions. In the NNM MIB Browser, you will see IGMP-MIB referenced in two MIB branches. To use the NNM MIB Browser for gathering information, use:
The two menu commands under the Multicast menu, Multicast Data Collection -> Monitor Group Traffic Collection and Multicast Data Collection -> Monitor Interface Traffic Collection now use a web interface. The web interfaces provide a Pause button. To sort by a column of your choice, click on the column title.
Prior to this patch, the native NNM user interface-based table had to be running in order to be able to use the web interface. With the patch, that requirement no longer exists.
If you encounter problems getting these menu commands working on your computer, check the following configuration files:
$OV_CONF/ovweb.conf
Verify that Browser, Host, and Port are set appropriately. Also verify that the browser specified in this file works correctly. Host and Port must match what is specified in httpd.conf (explained below). See the ovweb.conf manpage for full details.
/opt/OV/httpd/conf/httpd.conf
Verify that ServerName and Port match the values specified for Host and Port in ovweb.conf (explained above).
/apps/bin/netscape
Assuming that your preferred browser (as specified in ovweb.conf) is Netscape, verify that
/apps/bin/netscape
points to the
correct version of Netscape that is operational on your computer.
$OV_LRF/httpd.lrf
, etc.
Verify that your httpd process is started by ovstart. See the $OV_LRF/httpd.lrf
file and the lrf and
ovstart manpages for more details.
Optionally, you can ignore these two menu commands and bookmark the following URLs on any computer from which you can access the computer that hosts the Multicast SPI:
http://<Host>:<Port>/OvCgi/mcastgrptable.ovpl
http://<Host>:<Port>/OvCgi/mcastiftable.ovpl
Replace <Host>
with your Hostname, and replace <Port>
with the appropriate port number.
The default port number is 3443.
A new menu command, Locate & Highlight IP Address has been added under the Multicast menu.
With this menu command, you can locate the subnet or router object in the Multicast submap that contains the specified IP address. This menu command is useful for identifying where an IP address belongs in the map (in other words, which subnet or router) and can be used as part of troubleshooting multicast traffic to or from a specific IP address.
If the specified IP address belongs to one of the routers managed by the Multicast SPI, that router symbol and the connection-line (representing the interface) is highlighted.
Otherwise, the subnet symbol where the IP address exists is highlighted.
The Multicast:Clear Highlights menu command clears the highlights created by either Highlight PIM Designated Routers or Locate & Highlight IP Address.
Clear Highlights replaces the earlier menu command Clear PIM Highlights.
The Describe Multicast Object menu command now shows an enhanced structure for better readability.
Due to some changes in the Multicast menu, the accelerator keys for the menu commands have been changed.
managed.mmon
and unmanaged.mmon
It is now possible to specify IP address ranges using wildcards in the $OV_CONF/managed.mmon
and
$OV_CONF/unmanaged.mmon
files.
By default, your customized versions of these files are retained. To take advantage of the IP address wildcards,
see the comments section of the /usr/newconfig/etc/opt/OV/share/conf/managed.mmon
file for more details.
We recommend that you replace the comments in your $OV_CONF/managed.mmon
with those from the new file,
/usr/newconfig/etc/opt/OV/share/conf/managed.mmon
, so that you have this information for future reference.
mmon.conf
A few configuration options have been added or modified in the $OV_CONF/mmon.conf
configuration file.
By default, your customized version of this configuration file is retained. Changes to the configuration
options are explained as comments in the new version of the configuration file:
/usr/newconfig/etc/opt/OV/share/conf/mmon.conf
.
DO NOT OVERWRITE YOUR CURRENT $OV_CONF/mmon.conf
FILE.
The changes to the mmon.conf
file are as follows:
Tip: We recommend that you copy the comments for NODE_STATUS, DOMAIN_SUFFIX, TRIM_FWD_TREE_STATE, and DISCOVERY_VIA_SNMP from
/usr/newconfig/etc/opt/OV/share/conf/mmon.conf
to $OV_CONF/mmon.conf
,
so that you have this information for future reference.
Changes from NNM Multicast 2.0 with the Consolidated Patch to the Multicast Smart Plug-In for Network Node Manager 2.1
NOTE: The consolidated patch number is as follows:
Previous versions of NNM Multicast failed to display the forwarding tree on the single line used on the network map to represent multiple, parallel connections between routers (known as an OpenView "metaconnection"). This problem is fixed, and the forwarding tree is also correctly shown on the metaconnection submap.
Previous versions of NNM Multicast displayed forwarding trees using only two colors (one for shared tree, one for source-specific or shortest-path tree. Now the critical-status color (red) may also be used in a forwarding tree display. This color is used when data is not flowing along a portion of the tree, as reported by the routers. A pop-up message appears when this condition is detected during the display of a forwarding tree. This serves as a visual indication of a multicast fault, and aids in diagnosis of multicast issues.
In addition, the display of a forwarding tree now correctly follows the shared path for the next hop downstream if the incoming shortest-path route is not receiving data. Prior versions of NNM Multicast did not handle this correctly.
This version of the product adds new support for routers that utilize the ipMRouteStdMIB. Now both standard and experimental versions of the ipMRoute MIB are supported:
mmon.conf
A few configuration options have been added:
By default, disabled interfaces may result in "blue subnets" appearing on the map because the disabled interface may be the only multicast-enabled interface in the subnet. With no other object to define the subnet's status, it is unknown (blue).
Setting this parameter to 1 disables the display of "blue subnets" that are caused by disabled interfaces by eliminating all disabled interfaces from subnets. This can greatly reduce the number of objects on a multicast map.
The disabled interfaces will still be seen on router submaps, and via the Describe Multicast Object menu command when one or more routers is selected.
SNMP accesses may try for 1000 or more objects using SNMP v2C get-bulk. Some routers are overwhelmed by this. This parameter determines the maximum number of objects requested with each SNMP get-bulk request. This default value works with all routers, at the cost of reduced efficiency for more capable routers.
mmon_ma.conf
Three interface types have been added to mmon_ma.conf
:
For information about using this configuration file, see the Multicast Smart Plug-in Administrator's Guide, Chapter 2 "Installation and Configuration."
For Cisco and Foundry routers, interface labels will incorporate the standard short-form of the interface description. As examples:
Interface Description | Submap label text |
---|---|
Ethernet2/0 | Et2/0 |
ATM9/0/0.1-aal5 layer | AT9/0/0.1 |
GigabitEthernet4/14 | Gi4/14 |
********************************************************
Known Issues / Resolutions
********************************************************
Possible Conflicting Threshold/Rearm Traps in NNM
The Multicast SPI uses two SNMP trap OIDs within the number range reserved for in-house customer configurations of NNM threshold and rearm events:
If you configured custom threshold/rearm traps in NNM, please verify that these OIDs are not currently in use within your NNM configuration. If they are already in use, please modify your NNM configuration so that these OIDs are available to the Multicast SPI before installing the Multicast SPI.
To verify the NNM configuration for these OIDs:
If these OIDs are not listed, continue with the Multicast SPI installation.
If these OIDs are listed, reconfigure those two traps in NNM before installing the Multicast SPI. See the "Data Collection & Thresholds" section of the NNM manual, Managing Your Network with NNM, Chapter 11 "Customizing Events" for more information.
NNM Environment Variables Required
The Multicast SPI requires that the NNM environment variables be configured properly:
See the "Establishing Universal Pathnames" section of the NNM manual, Managing Your Network with NNM, Chapter 5 "Initial Network Discovery" for more information. Also, see the ov.envvars manpage.
Multicast Group Name Versus Group Class D IP Address
Several of the Multicast SPI dialog boxes include a field requesting that you specify the desired "Group." For static groups, specify the class D IP address assigned for this group’s use, rather than the group name.
To determine the class D IP address assigned for the group, at the command prompt, type:
nslookup <group name>
Logging and Tracing Switch Limitation
If you enable the logging and tracing feature provided with the Multicast SPI using multiple switches in the process registration files, you may find that the Multicast SPI quits working and the console window displays:
Usage Error: ....
Use the following guidelines:
Suggestion: Convert to using environment variables instead of -d, -k, -n switches. Continue using the -f switch.
See the Multicast Smart Plug-in Administrator's Guide, Appendix C "Logging and Tracing for the Multicast Smart Plug-in" for more information.
DO NOT USE Reflection X for:
The HP Auto Pass License Software does not work well in the Reflection X environment.
While using the HP Auto Pass licensing dialog boxes, use an HP-UX display on the HP-UX operating system or a Solaris display on the Solaris operating system.
While testing with Reflection X, occasionally the Multicast SPI dialog boxes (Java windows) appeared without borders. If this happens, close the NNM interface (ovw), completely exit your Reflection X session, and then restart Reflection X to fix the problem.
ovstatus mmonitor mtraffic
If you see the following error message:
824: SecurityModule.smCanRun: Error reading from local file
Simply restart that process. At the command prompt, type:
ovstart mmonitor
or ovstart mtraffic
This problem has been noticed the first time only after installation and configuration.
Problem After NNM Terminates Abnormally
If the NNM interface (ovw) terminates abnormally, the Multicast SPI processes may continue to exist. This situation causes unnecessary resource consumption and may prevent access to open the same map in read-write mode.
Look for the processes with the following names and kill them (kill -9 <pid>
):
/opt/OV/bin/mmap
/opt/OV/bin/JRE/bin/…/jre
/opt/OV/bin/mshowgrouptable
/opt/OV/bin/mshowinterfacetable
You might see font warnings in the terminal window in which you typed ovw to start the NNM interface (ovw).
You might also see the message:
Java HotSpotTM Server VM warning: Disabling implicit null checks
You can ignore these warnings or install the listed fonts.
Traffic Collection Tables Don't Automatically Refresh
If you start traffic collection tables (using the menu commands Multicast:Multicast Data Collection->Monitor ...) when the tables are empty, the tables are not automatically refreshed. After data collection has begun, close the web browser and re-open the traffic collection tables.
Missing Functionality for Alarms
Double-clicking an alarm in the Multicast Alert Alarms category of the NNM alarm browser results in the message
No object found
. Navigate to the multicast object in the NNM GUI (ovw) map.
The Alarms command on the router shortcut menu (available by right-clicking on a router) doesn't work. Filter alarms for a router in the Multicast Alert Alarms browser.
