What is Switching Database Manager?

Cisco Switching Database Manager (SDM) is a powerful software application used to manage and configure routers within Cisco IOS-based network infrastructures. It simplifies the setup, monitoring, and maintenance of routers by providing an easy-to-use graphical interface that combines the power of Cisco IOS with intuitive menus and wizards.

How does SDM work?

SDM is designed to automatically detect compatible routers, allowing administrators to quickly set up the desired routing protocol (e.g., OSPF, EIGRP, or BGP).

It then provides interactive menus and wizards for configuring various features such as Access Control Lists (ACLs), Quality of Service (QoS), Firewall policies, and static routes.

Once the configuration is complete, SDM allows users to instantly view changes in real-time, allowing for quick troubleshooting and monitoring of network activity.

Types of Switching Database Manager (SDM)

There are two versions of Cisco Switching Database Manager:

  1. Standard: The Standard version is designed for small and medium-sized businesses
  2. Advanced: The Advanced version is optimized for larger networks that require advanced features such as multicast routing, policy-based routing, and Virtual Private Networks (VPNs).

Both versions come with a range of software updates and technical support plans to ensure users are kept up-to-date with the latest features and developments. Additionally, Cisco provides an SDK to allow customers to develop their extensions and applications for SDM.

Benefits of Using Cisco SDM

Improved network performance

Cisco SDM simplifies the setup, monitoring, and management of routers by providing an intuitive graphical interface with easy-to-use wizards for configuring various features.

This improves performance by reducing complexity and allowing administrators to quickly configure routing protocols, Access Control Lists (ACLs), and Quality of Service (QoS). Additionally, it can be used to facilitate faster deployment times for services such as VoIP and Video-over-IP.

Reduced network downtime

SDM helps reduce the amount of time needed to diagnose and troubleshoot problems within a network. The graphical interface allows administrators to easily view changes in real-time, allowing them to quickly identify and resolve issues. This helps to reduce network downtime and improve reliability by allowing administrators to keep the network running smoothly.

Enhanced security

SDM provides tools for quickly configuring Access Control Lists (ACLs) and Firewall policies, which helps to improve the security of networks. Additionally, it supports VPNs which allow users to access sensitive data securely over the internet.

Increased scalability

SDM is designed to manage and configure routers within Cisco IOS-based network infrastructures, which makes it easier for administrators to expand the size of their networks. This allows businesses to add more users or devices without needing to completely reconfigure the entire network.

Better network management and troubleshooting

The intuitive graphical interface of SDM allows administrators to quickly view changes in real-time, which helps them identify and diagnose problems quickly.

Additionally, it provides wizards for configuring various features such as Access Control Lists (ACLs) and Quality of Service (QoS). This simplifies the setup and management of routers, allowing administrators to focus on more important tasks.

How to Configure Cisco SDM?

#1. Preparing for SDM Configuration

Before configuring Cisco Switching Database Manager, administrators must ensure that the router is running a compatible IOS version and is properly connected to the network. Additionally, they must create an account on the router as well as enable HTTP server services before they can access SDM.

#2. Configuring SDM using the Command Line Interface (CLI):

Administrators can configure SDM by running commands from the Cisco IOS command line. This requires users to be familiar with basic Cisco IOS syntax and terminology to properly configure features such as routing protocols, Access Control Lists (ACLs), Quality of Service (QoS) parameters, and much more.

#3. Configuring SDM using the Graphical User Interface (GUI):

The graphical user interface (GUI) of Cisco Switching Database Manager provides an intuitive way to configure various features within a router. This allows administrators to quickly set up routers with minimal effort, as they can use wizards to guide them through the configuration process.

This is especially useful for new users, as it simplifies the learning process. Additionally, the GUI provides an easy way to view changes in real-time, which helps administrators diagnose and troubleshoot problems quickly.

Cisco SDM Features and Capabilities

Network Traffic Management

Cisco Switching Database Manager (SDM) supports network traffic management, allowing administrators to monitor and configure the flow of data within their networks. This includes setting up routing protocols and configuring Quality of Service (QoS) parameters such as class-based weighted fair queueing (CBWFQ). Additionally, SDM allows users to configure Access Control Lists (ACLs) which specify which users or devices are allowed to access certain resources.

VLAN Management

SDM provides an intuitive interface for managing Virtual Local Area Networks (VLANs). Administrators can create, modify, and delete VLANs quickly and easily by using the graphical interface. Additionally, they can set up VLAN routing protocols and configure inter-VLAN communication protocols such as Dynamic Trunking Protocol (DTP).

QoS Management

Cisco SDM provides users with a powerful tool for managing Quality of Service (QoS) parameters within their networks. This includes configuring class-based weighted fair queueing (CBWFQ) as well as other QoS parameters such as traffic shaping and link fragmentation.

Port Management

SDM provides users with an intuitive way to manage ports within their networks. This includes setting up port security, as well as configuring ports for various services such as voice, data, and video. Additionally, administrators can easily view the status of each port in real-time.

Security Management

Cisco SDM also provides users with an easy way to manage security within their networks. By using Access Control Lists (ACLs), administrators can specify which users or devices are allowed to access certain resources.

Additionally, they can configure encryption protocols such as IPSec to increase the security of their networks. Finally, SDM allows administrators to monitor and audit user activity on the network to ensure compliance with organizational policies.

Best Practices for Using Cisco SDM

Regularly Monitoring Network Performance

It is important to regularly monitor network performance when using Cisco Switching Database Manager (SDM). This helps administrators identify potential problems before they become serious issues.

By regularly monitoring things like packet loss, latency, and jitter, administrators can quickly detect any irregularities in the network and take appropriate action.

Regularly Updating SDM

It is also important to regularly update Cisco SDM. This ensures that administrators are using the latest version of the software and have access to all of its features and capabilities. Additionally, regular updates help to ensure that the software is running as efficiently and securely as possible.

Properly Securing SDM

When using Cisco SDM, it is important to properly secure the software. This includes setting up strong passwords and limiting access to only those users who need it.

Avoiding Common SDM Configuration Mistakes

It is important to avoid common configuration mistakes when using Cisco SDM. This includes ensuring that all parameters are correctly configured and that there are no typos in the configuration. Additionally, administrators should carefully review any changes they make to ensure that they are not introducing any potential security vulnerabilities or negative performance impacts.

Troubleshooting Common Cisco SDM Issues
