Chassis View Card Operation in a Redundant Setup

This section describes how the primary and secondary cards are shown in Chassis View when they are in a redundant setup. The Chassis View behavior is changed based on the CHASSIS_SHOW_PHYSICAL_MAPPING_AND_HIDE_UNMANAGED_ALARMS flag set in the CMSCClient.conf file under the ~svplus/config directory.

When set to false

When two cards are in a redundant relationship, the primary card (also known as the logical slot) displays the ports and lines for all provisioning activities even if the primary slot becomes standby. No ports and lines are shown under the secondary slot even after it becomes active.

In Chassis View, the primary card displays the ports only if they are available in the active card. The secondary slot does not display the ports even if it becomes active.

When set to true

•For the controller and non–controller cards:

–When two cards are in a redundant relationship, the active card displays the ports and lines for all provisioning and troubleshooting activities.

–In Chassis View, the active card displays the ports only if they are available in the active card. In a redundant setup, Chassis View displays the lines and alarms under the active card.

However, this flag does not affect the tree view and other CWM applications. The logical slot in the tree view of a CWM application and the physical slot in Chassis View are maintained when you select an object in one application and drag it to another application.

•For the controller card only:

–Chassis View does not show unmanaged or unsupported alarms for PXM and RPM cards and unmanaged alarms for MGX nodes, such as the HIST and ACO alarms on the PXM cards.

–Chassis View does show the following in the active controller card: the shelfIntegrated alarm for MGX nodes, physical mapping (alarms and ports or lines) for redundant cards, and alarms that are similar to DCA, DCB, and ENET.

–Chassis View displays an Empty Reserved controller card as a blank card in the front view.

–If no back card or no secondary back card exists, Chassis View displays either card as a blank back card in the rear view.

RPM Card Behavior based on the Chassis View Flag Value

When the CHASSIS_SHOW_PHYSICAL_MAPPING_AND_HIDE_UNMANAGED_ALARMS flag value is set to true in the CMSCClient.conf file, unmanaged alarms, such as the CB_TX and CB_RX alarms on the RPM cards, are not shown in the RPM card in Chassis View.

Chassis View Operation after Card and Line Switchover

For a card switchover in a redundant setup, Chassis View behavior depends on the

CHASSIS_SHOW_PHYSICAL_MAPPING_AND_HIDE_UNMANAGED_ALARMS flag value set in the CMSCClient.conf file.

After line switchover, provisioning is allowed only on the working line of an automatic protection switching (APS) pair, whether the line is currently active or not. However, both the working and protection lines are monitored.

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.
