Configuring Transparent Bridging

Tuning the Transparently Bridged Network

To define a circuit group, use the following command in interface configuration mode:

Command

Purpose

 

 

bridge-group bridge-groupcircuit-group

Adds a serial interface to a circuit group.

circuit-group

 

 

 

For circuit groups of mixed-bandwidth serial interfaces, it might be necessary to configure a pause interval during which transmission is suspended to avoid misordering packets following changes in the composition of a circuit group. Changes in the composition of a circuit group include the addition or deletion of an interface and interface state changes. To configure a transmission pause interval, use the following command in global configuration mode:

Command

Purpose

 

 

bridge bridge-groupcircuit-group

Configures a transmission pause interval.

circuit-group pause milliseconds

 

 

 

For applications that depend on the ordering of mixed unicast and multicast traffic from a given source, load distribution must be based upon the source MAC address only. To modify the load distribution strategy to accommodate such applications, use the following command in global configuration mode:

Command

Purpose

 

 

bridge bridge-groupcircuit-group

Distributes base load on the source MAC address only.

circuit-group source-based

 

 

 

For an example of how to configure a circuit group, see the “Complex Transparent Bridging Network Topology Example” section later in this chapter.

Configuring Constrained Multicast Flooding

In a transparent bridge, multicast packets are flooded on all forwarding ports on the bridge. For some protocols, it is possible for a bridge to determine the membership of multicast groups, and constrain the flooding of multicasts to a subset of the forwarding ports. Constrained multicast flooding enables a bridge to determine group membership of IP multicast groups dynamically and flood multicast packets only on those ports that reach group members.

To enable constrained multicast flooding, use the following command in global configuration mode:

Command

bridge cmf

Purpose

Enables constrained multicast flooding for all configured bridge groups.

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.
