Chapter 2 Converting to an Integrated Switch System

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

Step 2 Move the disabled GE links between RPs and the backup Cat6K to the newly inserted 22-port SCGE cards. The following locations are listed:

•0/rp0-GE1 to F1/SC1-GE0

•0/rp1-GE1 to F3/SC1-GE0

•1/rp0-GE1 to F0/SC1-GE0

•1/rp1-GE1 to F2/SC1-GE0

Step 3 Use the show controllers switch inter-rack udld command in administration EXEC mode, with the all and location keywords, to verify that all of the new connections are bidirectional and have the correct neighbors.

The location is the location of the 22-port SCGE card.

Step 4 Use the show controllers switch stp location command in administration EXEC mode to verify that 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 the active Cat6K are in the forwarding state.

Step 5 Verify that there is no impact to the active topology and the control Ethernet traffic because the active Cat6K remains as the root.

Performing a Failover to a Standby 22-port SCGE (Four-FCC Multishelf System)

To perform a failover to a standby 22-port SCGE and swap the remaining SCGE with the new 22-port SCGEs, perform the following steps:

Step 1 Perform a failover to an FCC0, to the new 22-port SCGE. Use the following syntax for the redundancy switchover command, with the location keyword, in EXEC mode:

redundancy switchover location node-id

Replace the node-idargument with the location of the active 2-ports SCGE card.

Step 2 Verify that the failover is completed by using the show platform command and show redundancy command.

The show platform command shows that the 22-port SCGE card is in IOS XR RUN state.

The show redundancy command shows that the 22-port SCGE card is in the active state.

Step 3 After the 22-port SCGE becomes active, swap the 2-ports SCGE (active SC) with the new 22-port SCGE card.

Note Do not attempt this step before Step 2 has completed.

Step 4 Use the show platform command in EXEC mode or administration EXEC mode to verify that the newly 22-port SCGE is in the IOS XR RUN state.

Step 5 Use the show redundancy command in EXEC mode to verify that the newly inserted 22-port SCGE cards are in standby ready.

Step 6 Repeat Step 1 to Step 4 for FCC1, FCC2, and FCC3.

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.
