CWM Feature Limitations

set semsys:seminfo_semmsl=100 set rlim_fd_max=1024

After you have made the above changes, edit and configure the “SHMBASE” value in /usr/users/informix94/etc/onconfig as follows and reboot the machine:

SHMBASE 0x0A000000L

•Because of a VISM image issue, the CWM cannot update fax_jitt_mode and fax_jitt_initdelay in the vism_card table for a Fax jitter configuration change. This problem will be fixed in the next VISM release.

•Even though the VXSM T3 card is compatible with the MGX 8880 and 8850 PXM45 platform releases, the CWM software does not discover it.

•Cisco does not recommend pointing multiple CWMs at the same gateway node.

•When /usr/users becomes completely full, the orbix processes cannot write to the disk and continue operations. To correct the problem, free up disk space in /usr/users and then restart the orbix processes and the CWM as follows: Stop the core and exit out of the CWM prompt, run the stoporbix2000 script, type CWM (you should see “Starting Orbix...” in the ~svplus/log/.startStopOrbix.log file), and start the core.

•When the SSM is installed with the SCM Gateway configuration, the SCM GUI does not open when the primary SSM and secondary SSM are started simultaneously (or within a time gap of 30 seconds to 1 minute). Avoid this problem by waiting 2 to 3 minutes after starting core in the primary SSM before starting core in the secondary SSM in the SCM Gateway configuration.

•When a shortage of shared memory exists on the workstation, the Informix engine may generate an operating system error, as shown in this example:

shmat: [22]: operating system error

18:45:49 shmat: [22]: operating system error

18:45:57 Error writing '/tmp/shmem.1fd4555c.0' errno = 4

18:45:57 mt.c, line 10260, thread 7148, proc id 1008, errors occurred during mt_notifyvp.

When this error occurs, the statsparser is not able to perform database-related operations. The error can be resolved temporarily by changing the /etc/system configuration as follows:

forceload: sys/shmsys

forceload: sys/semsys

set shmsys:shminfo_shmmax=1073741824 set semsys:seminfo_semaem=16384

set semsys:seminfo_semmap=5000 set semsys:seminfo_semmni=8192 set semsys:seminfo_semmns=8192 set semsys:seminfo_semmnu=8192 set semsys:seminfo_semume=256 set semsys:seminfo_semvmx=50000 set shmsys:shminfo_shmmin=256 set shmsys:shminfo_shmmni=32000 set shmsys:shminfo_shmseg=256 set semsys:seminfo_semmsl=100

The long-term solution is to increase the amount of memory to support 2 million connections consistently.

•When using in-band management, only 50-KB connections are supported on the BPX-SES. To manage 100-KB connections on the BPX-SES, set up the CWM for out-of-band management.

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.
