kind of configuration can best meet security needs without compromising network performance? This article describes the following parts:
Cisco Router Security Configuration. Password Management
A vro uses a password to prevent unauthorized access to the vro and is a part of the security of the vro. The best way to han
The rapid development of wireless networks has also promoted the wide application of wireless routers. At present, the market demand is also very high. Here we recommend a Cisco wireless router, cisco's Linksys wireless products have always maintained Cisco's high quality. As a result, this WRT54GC Cisco Wireless
the PC: for example, use the TERMINAL program in WINDOWS, use COMl/2, 9600BPS, 8 data bit, 2 stop bit. Others use the default value. After the control port is connected, turn on the power switch of the router.
Initialize Installation
The vro must use a valid power supply. Generally, the zero-ground voltage of the power supply is less than 4 volts, and the zero-fire/ground-fire voltage is 220 volts. Ground Line Protection basically requires that the d
There are many knowledge about Cisco routers. Here we mainly analyze the specific methods for Cisco router configuration. Have you ever encountered this problem in daily network management and maintenance: You have been forcibly rejected by a vro or vswitch, a former "friend", because you forgot your password, paramete
Essential security commands for CISCO router initialization 1. Security Settings for vro Access Control 1. Strict control over the administrator who can access the vro. Record Filing is required for all maintenance tasks. Www.2cto.com 2. do not access the vro remotely. Even if you need to access the vro remotely, we recommend that you use the access control list and high-intensity
Maybe many people do not know the actual application of the NetEye firewall and the Cisco router. Next we mainly analyze the security problems of the NetEye firewall and the Cisco router. Firewall has become a key part of enterprise network construction. However, many users think that there are already routers in the n
It is very important to know some common knowledge about CISCO routers. Here we mainly explain the CISCO router tutorial, which provides a detailed analysis from configuration to access methods. This document uses Cisco2620 as an example to describe how to configure the vro and remote access, this article discusses how to use the DHCP service function of the inte

network will be fatal. Therefore, to improve security, the Cisco router sets password management for the Auxiliary port. Therefore, it is recommended that the network administrator do not use the same password as other passwords in password settings. Otherwise, the security
There are still many things worth learning about the Cisco router configuration mode. Here we will mainly introduce how to enter the detailed steps of the Cisco router configuration mode. In the Cisco router configuration mode, th
For many beginners, using cisco rommon to maintain a vro, the ROM Monitor of a cisco router is often unfamiliar or even daunting. The reason is simple. First, we do not often use this mode, I am not familiar with the related operations. Second, Operation errors in ROM Monitor mode often cause fatal damage to the vro (such as destroying the IOS file in flash, lead
Basic configurations of Cisco routers and switches: www.2cto.com Router> \ enter the user mode Router when the vro is started> enable \ type the command to enter the Router mode # \ This display mode indicates that the Router mode has been entered # configure terminal \ type
Cisco router configuration mode
In general, you can configure your router in 5 ways:
1.Console Port connection terminal or running terminal simulation software of the microcomputer;
2.AUX Port Connect modem, connect with remote terminal or computer running terminal simulation software by telephone line;
3. Via the TFTP server on the Ethernet;
4. Adoption of
access a vro, further configuration is required to restrict further access to the vro.
Most Cisco routers are still controlled through remote logon and do not adopt any encryption method. Communication Using Remote logon is transmitted in plain text, which easily exposes the logon password. Although CiscoIOS12.1 adopts the SSHl encryption method, there are still many problems. Before
Recently changed jobs, the company more than 40 people share a 20M bandwidth wireless network, the router for Cisco R2911. Boss, let me make a cacti to monitor Cisco routed network card traffic. The whole days can not get the SNMP data, finally to the routing permission to find that the last operation to the routing SNMP service off, leaving the document written
A Cisco router uses Cisco 3620 as the ios dhcp Server. the IP address of the fastethernet0 port connected to the Intranet is 192.168.1.4, And the L2 Switch uses two Cisco 2950, A layer-3 Switch uses a Cisco 3550. There are two VLANs in the network. To simplify the descriptio
number of Logon failures is 0.
This information shows your settings, including the default login delay of one second, and other additional information. It also tells you that the current vro is in normal mode, which means that the vro currently allows you to log on. If a Cisco router deems it attacked, it enters quiet mode and begins to reject all login operations. You can also configure an ACL to indicate
the figure below.
Configuration process and test procedure
Before implementing the configuration, check whether the hardware and software support VPN. For Cisco router configuration, the IOS version must be later than 12.0.6 (5) T and provide the IPSec function. This configuration is successfully configured on the Cisco rout
Here we will mainly introduce the configuration and initial installation of Cisco routers. Describes how to configure Cisco router settings and remote access, this article discusses how to use the DHCP service function of the internal network to allocate address information for users who remotely dial in and how to troubleshoot common vro faults.
