Back up and Restore Configuration Files using TFTP

-
This is a step-by-step approach to copy a configuration from a router to a TFTP server, and back to another router. Before you proceed with this method, make sure you have a TFTP server on the network to which you have IP connectivity.

Backup Procedure

  1. At the Router> prompt, issue the enable command, and provide the required password when prompted. The prompt changes to Router#, which indicates that the router is now in privileged mode.
  2. Copy the running configuration file to the TFTP server:
CE_2#copy running-config tftp:
Address or name of remote host []? 64.104.207.171
Destination filename [ce_2-confg]? backup_cfg_for_my_router
!!
1030 bytes copied in 2.489 secs (395 bytes/sec)
CE_2#

Restoring Procedure

  1. Open the configuration file with a text editor. Search for and remove any line that starts with "AAA".
    Note: This step is to remove any security commands that can lock you out of the router.
  2. Copy the configuration file from the TFTP server to a new router in privileged (enable) mode which has a basic configuration.
     Router#copy tftp: running-config
  Address or name of remote host []? 64.104.207.171
  Source filename []? backup_cfg_for_my_router
  Destination filename [running-config]?
  Accessing tftp://10.66.64.10/backup_cfg_for_my_router...
  Loading backup_cfg_for_router from 64.104.207.171 (via FastEthernet0/0): !
  [OK - 1030 bytes]
  1030 bytes copied in 9.612 secs (107 bytes/sec)
  CE_2#

7 Popular Layer 2 Attacks

A large number of common threats need to be considered when securing a network, but a frequently overlooked area is the security of the LAN. When people think about security, often they’re thinking specifically of the layers above Layer 2, but there’s no reason to limit a security plan to these upper layers.  A good security plan should account for  all  layers, from Layer 1 through Layer 7.   Here we are discussing about some of the most common Layer 2 attacks and how they operate. 1. Spanning Tree Protocol (STP) Attacks The Spanning Tree Protocol (STP) is used on LAN-switched networks. Its primary function is removing potential loops within the network. Without STP, Layer 2 LANs simply would stop functioning, because the loops created within the network would flood the switches with traffic. The optimized operation and configuration of STP ensures that the LAN remains stable and that traffic takes the most optimized path through the network.  If an att

QUESTION 21 Refer to the exhibit. The two connected ports on the switch are not turning orange or green. What would be the most effective steps to troubleshoot this physical layer problem? (Choose three.) A. Ensure that the Ethernet encapsulations match on the interconnected router and switch ports. B. Ensure that cables A and B are straight-through cables. C. Ensure cable A is plugged into a trunk port. D. Ensure the switch has power. E. Reboot all of the devices. F. Reseat all cables. Correct Answer: BDF QUESTION 22  A network administrator is troubleshooting the OSPF configuration of routers R1 and R2. The routers cannot establish an adjacency relationship on their common Ethernet link The graphic shows the output of the show ip ospf interface e0 command for routers R1 and R2. Based on the information in the graphic, what is the cause of this problem? A. The OSPF area is not configured properly. B. The priority on R1 sho

Nine Switch Commands Every Cisco Network Engineer Needs to Know

1. hostname Syntax:   hostname   hostname One of the most basic network commands,  hostname  configures the hostname used for a device. This hostname identifies the device to other locally connected devices for protocols such as the Cisco Discovery Protocol (CDP), which helps in the identification of devices attached directly to the network. Although it is not case-sensitive, the hostname must follow certain rules: It must begin with a letter and end in a letter or digit, and interior characters must be letters, digits, or hyphens (-). 2. ip default-gateway Syntax:   ip default-gateway  gateway The  ip default-gateway  command configures the default gateway for a switch when IP routing is  not  enabled (with the  ip routing  global configuration command), which is typical when lower-level Layer 2 switches are being configured. The easiest way to determine whether IP routing has been enabled is to run the  show ip route  command. When IP routing has not bee
