Configuring Transparent Bridging

Transparent and SRT Bridging Configuration Task List

Command

no ip routing

ip routing

Purpose

Disables IP routing.

Enables IP routing.

All interfaces in the bridge group that are bridging IP should have the same IP address. However, if you have more than one bridge group, each bridge group should have its own IP address.

Enabling Autonomous Bridging

Normally, bridging takes place on the processor card at the interrupt level. When autonomous bridging is enabled, bridging takes place entirely on the ciscoBus2 controller, significantly improving performance. Autonomous bridging is a high-speed switching feature that allows bridged traffic to be forwarded and flooded on the ciscoBus2 controller between resident interfaces. If you are using the ciscoBus2 controller, you can maximize performance by enabling autonomous bridging on the following ciscoBus2 interfaces:

MEC

FCIT transparent

HSSI HDLC

Although performance improvements will be seen most in the resident interfaces, the autonomous bridging feature can also be used in bridge groups that include interfaces that are not on the ciscoBus2 controller. These interfaces include the CTR, FCI with encapsulation bridging, and HSSI with encapsulation other than HDLC, such as X.25, Frame Relay, or SMDS, MCI, STR, or SBE16.

If you enable autonomous bridging for a bridge group that includes a combination of interfaces that are resident on the ciscoBus2 controller and some that are not, the ciscoBus2 controller forwards only packets between resident interfaces. Forwarding between nonresident and resident interfaces is done in either the fast or process paths. Flooding between resident interfaces is done by the ciscoBus2 controller. Flooding between nonresident interfaces is done conventionally. If a packet is forwarded from a nonresident to a resident interface, the packet is conventionally forwarded. If packets are flooded from a nonresident interface to a resident interface, the packet is autonomously flooded.

To enable autonomous bridging on a per-interface basis, use the following command in interface configuration mode:

Command

Purpose

 

 

bridge-group bridge-groupcbus-bridging

Enables autonomous bridging (if using the ciscoBus2 controller).

 

 

Note You can filter by MAC-layer address on an interface only when autonomous bridging is enabled on that interface. If any filters or priority queuing is configured, autonomous bridging is automatically disabled.

Configuring LAT Compression

The local-area transport (LAT) protocol used by Digital and Digital-compatible terminal servers is one of the common protocols that lacks a well-defined network layer (Layer 3) and so always must be bridged.

BC-23 specifications

Cisco Systems has long been a leader in the networking industry, and its BC-23 model exemplifies the company's commitment to innovation and performance. Aimed at enhancing business operations, the BC-23 is tailored for organizations looking for robust solutions that support their digital transformation efforts.

One of the standout features of the Cisco BC-23 is its advanced networking capabilities. It supports high-speed data transmission, enabling seamless communication across networks. With multi-gigabit Ethernet ports, the BC-23 facilitates faster data rates, accommodating the increasing bandwidth demands of modern applications. This feature is particularly beneficial for businesses that rely heavily on cloud services, video conferencing, and data-heavy applications.

Security is a top priority, and the Cisco BC-23 incorporates cutting-edge security measures. Integrated threat detection and prevention systems help safeguard sensitive data from cyber threats. Additionally, the device supports secure access protocols, ensuring that only authorized users can connect to the network. This multi-layered security approach not only protects the network infrastructure but also secures the integrity of the data being transmitted.

Another significant characteristic of the BC-23 is its support for software-defined networking (SDN). This technology allows businesses to manage their networks through centralized software applications, facilitating real-time adjustments and optimizations. The flexibility afforded by SDN is especially advantageous in dynamic environments where network demands can shift rapidly.

The Cisco BC-23 also offers enhanced management features, allowing IT teams to monitor network performance and analytics effectively. This visibility into network operations enables organizations to identify potential issues before they escalate, minimizing downtime and keeping business processes smooth.

Furthermore, the BC-23 is designed for scalability. As organizations grow, their networking needs evolve, and the BC-23 can easily adapt to these changes. Businesses can add additional devices and capabilities without the need for a complete overhaul of their existing infrastructure.

With its combination of speed, security, and scalability, the Cisco Systems BC-23 is an invaluable asset for modern businesses. It stands out not just as a networking device but as a comprehensive solution that meets the demands of today's fast-paced, technology-driven environment. As companies continue to leverage digital tools for growth and efficiency, the BC-23 will undoubtedly play a significant role in their success.
