Configuring Transparent Bridging

Transparent and SRT Bridging Configuration Task List

Determining Access for Bridging

You can determine access by either permitting all bridge packets or by controlling access according to Ethernet type codes.

To permit all transparent bridge packets, use the following command in global configuration mode:

Command

Purpose

 

 

dialer-list dialer-groupprotocol bridge

Defines a dialer list that permits all transparent bridge packets.

permit

 

 

 

To control access by Ethernet type codes, use the following commands in global configuration mode:

 

Command

Purpose

Step 1

 

 

access-listaccess-list-number

Permits packets according to Ethernet type codes (access list numbers

 

{permit deny} type-code [mask]

must be in the range 200 to 299).

Step 2

 

 

dialer-list dialer-groupprotocol

Defines a dialer list for the specified access list.

 

bridge list access-list-number

 

 

 

 

For a table of some common Ethernet types codes, see the “Ethernet Types Codes” appendix in the Cisco IOS Bridging and IBM Networking Command Reference, Volume I.

Configuring an Interface for Bridging

You can configure serial interfaces or ISDN interfaces for DDR bridging. To configure an interface for DDR bridging, use the following commands beginning in global configuration mode:

 

Command

Purpose

Step 1

 

 

interface type number

Specifies the serial or ISDN interface and enter interface

 

 

configuration mode.

Step 2

 

 

dialer string dial-string

Configures the dial string to call.

 

dialer map bridge [name hostname]

or

 

[broadcast]dial-string[:isdn-subaddress]

Configures a dialer bridge map.

 

 

Step 3

 

 

bridge-group bridge-group

Assigns the specified interface to a bridge group.

 

 

 

Configuring Transparent Bridging over Frame Relay

The transparent bridging software supports bridging of packets over Frame Relay networks. This ability is useful for such tasks as transmitting packets from proprietary protocols across a Frame Relay network. Bridging over a Frame Relay network is supported both on networks that support a multicast facility and those that do not. Both cases are described in this section.

Fast-Switched Transparent Bridging

The transparent bridging software provides fast-switched transparent bridging for Frame Relay encapsulated serial and High-Speed Serial Interface (HSSI) networks.

Switched virtual circuits (SVCs) are not supported for transparent bridging in this release. All the Permanent virtual circuits (PVCs) configured on a subinterface must belong to the same bridge group.

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.
