In-depth analysis of Cisco router configurations

As a leader in the routing industry, there is a lot of market demand. Here we mainly analyze the Cisco router configuration issues. Cisco SDM is based on Cisco IOS? An intuitive Web device management tool developed by Software routers. It simplifies Cisco router configurations through smart wizard, so that customers and Cisco partners do not need to understand the CLI) can we quickly and easily deploy, configure, and monitor Cisco Systems? The company's router. Many Cisco router configurations and Cisco IOS Software versions support Cisco SDM.

Ease of use and Application Intelligence

With Cisco SDM, users can not only easily configure routing, switching, security, and service quality QoS on Cisco routers, but also actively manage performance monitoring. Now, Cisco SDM users can remotely configure and monitor Cisco routers, instead of using the command line interface of Cisco IOS software. The Cisco sdm gui can help non-expert Cisco IOS software users complete routine operations, provide easy-to-use smart wizard, automatically perform router security management, and help users complete the online help and training process.

Using the Cisco SDM smart wizard, you can systematically configure a LAN, wireless LAN and WAN interface, firewall, Intrusion Prevention System IPS, and IP SecurtiyIPSec) VPN to gradually complete the Cisco router configuration. The Cisco SDM smart wizard can intelligently detect error configurations and propose repair suggestions. For example, if the WAN interface is specified by DHCP, Dynamic Host Configuration Protocol DHCP is allowed) traffic passes through the firewall. In addition to detailed steps to help users enter correct data in Cisco SDM, online help embedded in Cisco SDM also provides the corresponding background information. Network and security terms that users may encounter are included in the online vocabulary.

For network experts familiar with Cisco IOS Software and its security features, Cisco SDM provides advanced configuration tools that can quickly configure and precisely adjust the security features of routers, this allows network experts to review commands generated by Cisco SDM before providing Cisco router configuration change solutions. With Cisco SDM, administrators can use SSL and SSHv2 protocol connections to configure and monitor routers remotely. Using this technology, you can establish a secure connection between your browser and vro through the Internet. When deploying a branch office, you can configure and monitor the Cisco SDM Router from the headquarters of the company, thus reducing the requirements of the branch office for senior network administrators.

Integrated Security Configuration

When deploying a new router, you can use Cisco SDM to quickly configure Cisco IOS Firewall using best practices recommended by the ICSA and Cisco technical support center TAC. Cisco SDM users can configure the strongest VPN default values and automatically perform security audits. In addition, Cisco SDM users can perform step-by-step router locking for the firewall and quickly deploy secure site-to-site connections through step-by-step VPN. Using the IPS feature table bundled with Cisco SDM recommended by Cisco, you can quickly deploy worm, virus, and protocol attack defense systems.

When using Cisco SDM to call a vro that has been configured, you only need to perform one security audit step to evaluate the security advantages and weaknesses of the Cisco vro configuration. The administrator can precisely adjust the original router security configuration to better meet enterprise requirements. In addition, Cisco SDM can also be used for routine operations, such as monitoring, error management, and troubleshooting.

Cisco router configuration

In addition to security configuration, Cisco SDM can also help users quickly and easily perform Cisco router configurations, such as LAN, WLAN and WAN interface configuration, dynamic routing, DHCP server, and QoS policy. By using the LAN Configuration Wizard, you can not only assign IP addresses and subnet masks to Ethernet interfaces, but also enable or disable DHCP servers. The WAN Configuration Wizard allows you to configure xDSL, T1/E1, Ethernet, and ISDN interfaces for WAN and Internet access. In addition, for serial connections, you can also implement frame relay, PPP, and advanced Data Link Control HDLC encapsulation. In addition, Cisco SDM allows you to configure static routes and common dynamic routing protocols, such as OSPF, RIP 2nd, and VPN.

Now, using Cisco SDM, QoS policies can be easily applied to any WAN or VPN channel interface. The QoS policy wizard can automatically implement Cisco QoS policy architecture principles to effectively distinguish real-time application speech or video) key business application structured query language [SQL], Oracle, Citrix, routing protocol, etc.) traffic and other network traffic Web, email, etc ). With network-based application identification (NBAR) monitoring in Cisco SDM, users can inspect application-layer traffic in real time in a visualized manner, and continuously analyze the impact of QoS policies on various application traffic.

Monitoring and Troubleshooting

In the display mode, Cisco SDM can quickly display the status and performance data of important router resources in a graphical manner, such as interface status normal or abnormal), CPU and memory usage. For wireless models, Cisco SDM fully supports real-time 802.11a/B/g interface statistics. Cisco SDM can use integrated routing and security features on routers to diagnose WAN and VPN connections in depth and eliminate faults in a timely manner. For example, when a VPN connection is rectified, Cisco SDM checks the Cisco router configurations and connections from the WAN interface layer to the IPSec Crypto Map layer. When you test the configuration and remote peering connection at each layer, Cisco SDM provides the success or failure status, possible causes of failure, and repair suggestions from Cisco TAC.

Using the Cisco SDM monitoring mode, users can not only calculate the number of network access attempts rejected by Cisco IOS Firewall, but also access Firewall records. In addition, you can monitor detailed VPN status information, such as the number of packets encrypted or decrypted by the IPSec channel and the connection details of the Easy VPN Client.
