information in other storage regions The previously introduced method of sending log information to the line has a drawback. If we do not see the screen output of the connection line, the message is rolled over the screen and exceeds the historical cache of the terminal software, then we will not be able to see the lost messages. To avoid this problem, we often send log information to other storage areas, including the internal cache of the device, the system log server, and the SNMP Management

password. this is the default password of all cisco routers. we need to change it right now. use this one: Username cisco privilege 15 secret 5 cisco Config the E1 PRI card There is the T1/E1 card delivered with the router.

When we want to perform permission rating management on a Cisco router or switch, it is often necessary to assign different levels of users a command that exceeds the default settings, such as show run, which is the most basic troubleshooting command.However, the command cannot be executed when your user level is at 0-14. You can assign permissions to these users

that you need a user and a password to gain access. In addition, we recommend that you use a secret password for your username, instead of a common password. It uses MD5 encryption to encrypt passwords, and greatly improves security. Example: Router (config) # username root secret My $ Password After the user name is configured, you must enable the port using the user name. Example:◆ Router (config) # line

A major part of enterprise security policy is to implement and maintain firewalls, so firewalls play an important role in the implementation of network security. Firewalls are typically located on the edge of the corporate network, which isolates the internal network from the Internet, or with other external networks, and restricts network visits to protect the internal network of the enterprise. The purpose of setting up a firewall is to establish a unique channel between the intranet and the e

Vswitches need to be configured for the recently merged server link set... I have never obtained a vswitch before. I want to sell it now... Generally, the vswitch supports telnet. If you have configured an ip address, you can directly telnet the vswitch. If you do not have any configuration, you need to use the Serial port. Choose Serial for the Serial port... Fortunately, we support all the omnipotent putty tools. If you use a tool, you can also choose Secure CRT... Enter the password after l

In Cisco command configuration tip 1, we talked about using the Range Command to simplify our configuration. However, if we often operate on a group of discontinuous ports Such as interface-range fa1/1, fa1/3, fa1/5, fa1/7, fa1/11 Even using the Range Command is cumbersome. We always think that the simpler

Privileged mode router # administrators can view and change configurations in this mode. I believe that it is absolutely important to have a set of passwords at this level. To switch from user mode to privileged mode, the administrator needs to enter the enabel

Which command standard do you want Cisco to use on each vro? Each administrator configures the commands of each vro correctly. The ten commands in this article are what I think you should configure on each vro, with no special order. 1. configure a Logon account on the vro I strongly recommend that you configure a real user name and password account on the vro and vswitch. This means that you need a user an
