Transferring an Active Cat6K Gigabit Ethernet Connections to the Active 22-port SCGE (Single-FCC Multishelf and Two-FCC Multishelf Systems)

To transfer the active Cat6K GE connections to the active 22-port SCGE and isolate the active Cat6K from the control network, perform the following steps:

Step 1 Disable the active Cat6K links that are connected to the active RP on the Designated Shelf Controller (DSC).

Step 2 Use the show controllers switch inter-rack stp command in administration EXEC mode to verify on the active RPs that the GE1 port, which is connected to the 22-port SCGE, goes into the forwarding (FWD) state.

The location is the location of the active RP.

Step 3 Shut down the ports on the active Cat6K one at a time, with the exception of the four links between an active Cat6K and the 22-port SCGE. Now, the active Cat6K remains connected to the fabric chassis with four GE links.

Step 4 Use the show controllers switch inter-rack stp command in administration EXEC mode to verify on all RPs that the GE1 port, which is connected to the 22-port SCGE, goes into the forwarding (FWD) state.

Step 5 Move the disabled GE link connecting the RPs and the active Cat6K link to the 22-port SCGE card.

Step 6 Use the show controllers switch inter-rack stp command in administration EXEC mode to verify on all RPs that the GE0 port, which is connected to the 22-port SCGE, goes into the blocked (BLK) state.

Step 7 Raise the priority of active Cat6K to 40960, which causes the root to change to 22-port SCGE on rack FCC0.

Step 8 Use the show controllers switch inter-rack stp command in administration EXEC mode to verify that the active SC on FCC0 is the new root switch.

Step 9 Shut down the port that is connected to the active Cat6K on each of the 22-port SCGEs. Step 10 Verify that there is no impact to the active topology and the control Ethernet traffic.

The migration is complete after you validate the new connections. You can remove the two

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.
