Chapter 2 Converting to an Integrated Switch System

How to Convert from the Cisco Catalyst 65xx Switch to the Integrated Switch System for Single-FCC Multishelf and

Two-FCC Multishelf Systems

Replace the interface number argument with the port that is connected to the active Cat6k.

Replace the node-idargument with the newly inserted standby 22-port SCGE card.

The following example sample output displays information for STP from the show controllers switch inter-rack stp command:

RP/0/RP0/CPU0:router(admin)# show controllers switch inter-rack stp ports 0 location

GE_0 of MST1 is designated forwarding

For the 22-port SCGE ports which are connected to each other, one is in the forwarding state and the other is in the blocked state.

Transferring the Backup Cisco Catalyst 65xx Switch Gigabit Ethernet Connections to a Standby 22-port SCGE (Single-FCC Multishelf and Two-FCC Multishelf Systems)

To transfer the backup Cisco Catalyst 65xx switch GE connections to a standby 22-port SCGE card and to isolate the backup Cisco Catalyst 65xx switch from the control network, perform the following steps:

Step 1 Shut down the ports on the backup Cat6K one at a time. Make the interCat6K port the last port to shut down.

Step 2 Move the disabled GE connections between the active RPs (on both the LCC in case of a 2 FCC MC) and the backup Cat6K to the standby 22-port SCGE.

Step 3 Use the show controllers switch stp command, with the location keyword, in administration EXEC mode, to verify that the RP ports (GE1) that are connected to the 22-port SCGE are in the blocked state, and that the RP ports (GE0) that are connected to an active Cat6K are in the forwarding state, as shown in the following syntax:

show controllers switch inter-rack stp location node-id

Replace the node-idargument with the location of the 22-port SCGE card. In addition, you can use the newly inserted standby 22-port SCGE card.

CRS-1 specifications

Cisco Systems' Carrier Routing System (CRS-1) is a cutting-edge, high-capacity router designed to meet the demands of service providers and large enterprises. Introduced in the early 2000s, the CRS-1 represents a significant leap forward in routing technology, offering unparalleled performance, scalability, and reliability.

One of the primary features of the CRS-1 is its exceptional scalability. The system is built on a modular architecture that allows for easy upgrades and expansions. This enables service providers to start with a configuration that suits their immediate needs while having the flexibility to expand as traffic demands grow. The CRS-1 supports a wide range of line cards, enabling data, voice, and video to be managed on a single platform, which simplifies network management and reduces operating costs.

The CRS-1 leverages advanced technologies that enable it to deliver impressive performance. With the ability to handle up to 92 terabits per second of throughput, the router is capable of supporting a vast number of connections, making it well-suited for large-scale service providers and data centers. This level of performance is powered by Cisco’s proprietary silicon technology, which optimizes the packet forwarding process and enhances overall efficiency.

Another key characteristic of the CRS-1 is its strong focus on reliability and redundancy. The system is designed with high availability in mind, ensuring that it can continue to operate seamlessly even in the event of hardware failures. Redundant components, such as power supplies and route processors, allow the CRS-1 to maintain its performance and uptime, a critical requirement for mission-critical network operations.

Additionally, the CRS-1 supports a wide variety of protocols and technologies, including Internet Protocol (IP), Multiprotocol Label Switching (MPLS), and various service provider features. This versatility makes it a compelling choice for organizations looking to implement advanced networking capabilities, such as Quality of Service (QoS) and traffic engineering.

In summary, the Cisco Systems CRS-1 stands out as a formidable solution for modern routing needs. Its modular design, exceptional scalability, robust performance, reliability, and support for multiple protocols and services make it an ideal choice for service providers and enterprises seeking to future-proof their networks. As the demand for bandwidth continues to surge, the CRS-1 remains a pivotal component in the evolution of networking infrastructure.
