This article describes in detail what a CAR is, how to configure a CAR, how to check whether a CAR works on the corresponding port, and so on. I believe this article will help you. Many organizations have established internal networks because of their work needs. Large Enterprises and organizations may also have established wide area networks (WAN ). There are many types of applications on the network. To ensure the good operation of the main applications, traffic control must be performed on th

The Cisco router switch sets automatic backup for IOS files and restores the automatic backup and rollback of Cisco IOS configuration files. The archive configuration mode function of IOS is required. Generally, only IOS versions 12.3 (4) All commands for automatic backup of the Cisco IOS configuration file are as foll

Use a cisco router to simulate how to configure a frame relay switch (configure 3640 as a frame relay switch): 3640 (config) # frame-relay switching ---------------------- enable the frame relay switching function of the router 3640 (config) # int s0/0 ------------------------------------- enter the s0/0 interface 3640 (config-if) # no ip add --------------------

I. Overview: In the actual work can often see a strong SSL VPN can bypass deployment, and support routing mode and NAT mode: Router mode requires intranet to VPN assigned address pool address can be router; NAT mode, VPN Client access intranet host, intranet host sees address as VPN interface address, Therefore, the address intranet of the VPN address pool is not required to be routed. If you want to test

This article introduces some examples of the cisco router show command. in the network, the network administrator should know the status of the router at any time, so as to promptly troubleshoot the fault. The show command can be run in both user and privileged modes. "show ?" Command to provide a list of available show commands. Show interfaces:Display the sta

RGMP is designed to be used in combination with the multicast routing selection protocol that supports the distribution tree Join/Prune. The typical protocol is PIM-SM. The RGMP protocol only specifies the IPv4 multicast route selection operation, excluding IPv6. The Cisco router port Group Management Protocol makes up for the shortcomings of the Internet group management protocol in the snoopIng technical

RGMP: Cisco router port group management protocol (rgmp) makes up for the Internet group management protocol (Igmp: Internet group management protocol) problems in snoopIng technical mechanisms. The rgmp protocol acts between multicast routers and switches. Rgmp allows you to fix multicast data packets forwarded by vswitches in the required vro. Rgmp is designed for backbone swItched networks, which is conn

This will be easy to deal with when you encounter the Internet and data failure. The following small series to you recommend the router debugging simple steps: 1. Use the Cisco router Debug cable to connect th

Assume that two Cisco routers and R1 (server) connect to R2 (client) to form a simple chained lan. DHCP is implemented below. The configuration commands and explanations are as follows: 1. Configure the R1 dhcp Service Dhcp # configure terminal // Enter global Mode Dhcp (config) # service dhcp // Enable the dhcp Function Dhcp (config) # no ip dhcp conflictlogging // Disable dhcp logging Dhcp (config) # ip dhcp pool

The user checks network security and requires SSH logon to the core device. Previously, the device used Telnet logon, and the user name and password are transmitted in plaintext, which does not meet the security check requirements. In fact, the SSH login configuration is very simple, mainly divided into the following steps: 1. Configure the Domain Name Sd_core_r7600 (config) # IP domain-name sdcore 2. generate an SSH key Sd_core_r7600 (config) # crypto key generate RSA The name for the keys will

You can configure a serial interface through a virtual terminal. to configure a serial interface, follow these steps: 1. In Global mode, enter the command "interface serial 0" to enter the serial interface configuration mode. 2. Each connected serial interface must have an IP address and subnet mask to forward IP packets, in interface configuration mode, enter the "ip address 3. If the serial interface is connected to a DCE device, we also need to configure a clock frequency for the serial inte
