Installing and Uninstalling CWM 15.3.00 P1

•Security Profiles

Before CWM 15.3.00 P1, a CWM user had to have a valid UNIX user because the user was authenticated against UNIX when he or she logged in to the CWM.

As of CWM 15.3.00 P1, a new feature has been added to support CWM login without depending on UNIX user accounts. With the new procedure, you add and configure users using the Security Manager. Because this feature is configurable, you can use the new feature or use the previous CWM authentication process.

•CWM Database

After creating a new database with the coldstart script, a database inconsistency will result if the CWM is restarted (stop core and start core) before it is synchronized with the network. In this case, rerun the coldstart script; do not use the SV+CreateDb tool. When a gateway node is upgraded or rebuilt before the CWM has synced up with the network, the CWM must be cold-started (create the CWM database and then restart the CWM) to ensure CWM database consistency. For the IGX ports, the asi_line table is populated with the 1-based port number and not the 0-based port number.

•RPM Management Limitations

The RPM-PR card is not supported on MGX PXM1-based nodes that Chassis View manages. The applicable trap is missing so the CWM cannot monitor the back card. For the RPM and RPM-PR cards in the standby state, the status displays as blue, not yellow as on other card types. For the RPM and RPM-PR card types, hardware and firmware revisions are not populated in the database.

The RPM back card support feature is disabled by default. To enable the feature and obtain RPM back card information, edit the emd.conf file before starting the CWM core. Note that when back card support is enabled, back card information is polled from the switch only during a coldstart or a manual resync. After that, any back card configuration or status changes are not updated until you perform another coldstart or a manual resync.

The CWM does not distinguish between the Ethernet back card versions installed with the MGX-RPM-128M/B or RPM-PR. No difference in functionality exists.

•Equipment Management Configuration Notes

In the emd.conf file, the OORequest and OOStart parameters should be customized, depending on network. The OORequest parameter defines the number of configuration files per node that can be requested at one time, with a maximum of 32 configuration files concurrently per node. The range is 1 through 32, and the default is 32. The OOStart parameter defines the number of OOEMC child processes. The range is 1 through 25, and the default is 6.

All of the PNNI nodes that the CWM manages (PXM45-based 8950, 8880, and 8850 nodes; PXM1E- based 8950, 8850, and 8830 nodes; and BPX nodes with SES shelves) are distributed among OOEMC processes.

The number of nodes that a single process manages is computed by dividing the number of PNNI network nodes by the number of processes that OOStart defines. Assume that the number of nodes that one process manages is called MANAGED_NODE_COUNT. Then, MANAGED_NODE_COUNT * OORequest must be less than or equal to 200, which can be achieved by increasing the OOStart or reducing the OORequest. The normal range of OOStart is 5 to 20. If the OOStart value is increased beyond 10, the number of DMD processes has to be increased or the shared memory overflows.

•Network Monitor Server Configuration File (NMServer.conf)

Two parameters in the NMServer.conf configuration file—HELLO_EVENT_INTERVAL and EVENT_REDELIVERY_COUNT—are tied to the NMSERVER_DISCONNECT_TIMEOUT parameter in the CMSCClient.conf client configuration file. The NMSERVER_DISCONNECT_TIMEOUT parameter value needs to be set to the same number as

15.3.00P1 specifications

Cisco Systems 15.3.00P1 is a pivotal release in the evolution of Cisco's IOS (Internetwork Operating System). This version introduces a range of features and enhancements aimed at improving network reliability, security, and performance. Built to support various networking scenarios, 15.3.00P1 serves as a robust platform for enterprises and service providers alike.

One of the standout features of 15.3.00P1 is its enhanced support for IPv6, which is increasingly vital as the internet continues to evolve. This version includes improved routing protocols and mechanisms that allow seamless integration and transition between IPv4 and IPv6. This dual-stack support ensures that network operators can manage their resources efficiently while preparing for the future.

Quality of Service (QoS) enhancements in Cisco IOS 15.3.00P1 help prioritize critical traffic flows, enabling organizations to allocate bandwidth according to application needs. This is particularly beneficial in environments where latency-sensitive applications, such as VoIP and video conferencing, are prevalent. The precise control over traffic helps reduce congestion and ensures a smooth user experience.

Security features have been significantly bolstered in this release. It includes advanced threat detection capabilities and improved access control lists (ACLs), allowing for more granular security policies. The enhanced security framework helps protect network devices from a variety of threats, ensuring that data integrity and confidentiality are maintained.

Another critical improvement in this version is its enhanced multicast routing capabilities. This is particularly essential for organizations utilizing video or other bandwidth-intensive applications that require efficient data delivery to multiple endpoints. The use of protocols such as Protocol Independent Multicast (PIM) facilitates efficient routing and reduces bandwidth consumption.

Cisco 15.3.00P1 also features better support for various hardware platforms, ensuring compatibility and optimal performance across Cisco routers and switches. The architecture enhancements allow for improved system resource management, reducing operational overhead while maximizing performance.

In addition to these features, the release incorporates several bug fixes and performance optimizations, addressing issues in previous versions. This attention to detail not only enhances system stability but also contributes to a more streamlined user experience.

Overall, Cisco Systems 15.3.00P1 represents a significant step forward in network operating systems, with its array of security, performance, and management enhancements making it an ideal choice for modern networking environments. Organizations deploying this version can expect improved operational efficiency and a more secure networking experience.
