Feature Limitations

CWM Feature Limitations

•These VISM 3.1 features introduced cannot be accessed from the CWM: TGCP, Dynamic Payload, and T.38 Fax Relay.

•The CWM database is not populated with the MPG configuration data. Instead, the Service Agent accesses the configuration directly from the switch.

•These cards are not supported by CWM 15.3.00 P1: the BME card and the FRSM12, URM, ARM, FRM, BTM, ALM and CVM service modules. To take advantage of the GUI enhancements, you must upgrade to the newer service modules supported in releases after CWM 12.0.

•These are the Current Route feature limitations:

–P2MP calls and SVC/SVP connections are not supported.

–Only master-ended (not slave-ended) connections have current route information.

–The configuration upload file contains only a snapshot of the current route information at the time the switch receives a CWM configuration upload request.

–If a node becomes congested, both of the connTrace messages that the command line interface (CLI) and the Current Route feature send are dropped. The CWM does not distinguish between the messages. This situation is also true for a connTrace ACK message received on a congested node.

–When a node ID is changed, follow this procedure on each network node to flush out all existing current route information and start collecting new information. Disable and re-enable the current route feature by using the cnfndcurrte command. After disabling the feature, wait for at least 9 seconds (the timeout period for a conntrace message) before re-enabling the feature to avoid processing stale conn-trace messages.

–Because the path information for a connection traversing more than 20 nodes is not stored in the current route path table, the connection does not have current route information.

•While the CWM is running, if the remote display is stopped without properly shutting down the CWM desktop, reopening it remotely may not succeed.

The following are known CWM feature limitations:

•For a few of the latest Solaris patches and the Sun Fire E6900 server, the Informix engine may generate a shared memory error as shown in this example:

"oninit: Fatal error in shared memory creation <machine name>"

When this error occurs, the Informix engine fails to come up and is not able to perform database related operations.The error can be resolved by changing values in the /etc/system and /usr/users/informix94/etc/onconfig files. The following shows the change to the /etc/system file:

forceload: sys/shmsys

forceload: sys/semsys

set shmsys:shminfo_shmmax=268435456 set semsys:seminfo_semaem=16384 set semsys:seminfo_semmap=64

set semsys:seminfo_semmni=4096 set semsys:seminfo_semmns=4096 set semsys:seminfo_semmnu=4096 set semsys:seminfo_semume=64 set semsys:seminfo_semvmx=32767 set shmsys:shminfo_shmmin=100 set shmsys:shminfo_shmmni=100 set shmsys:shminfo_shmseg=100

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.
