In Special encryption feature sets, enhanced IP Sec 56 and enhanced IPSec 3DES can be provided. To create an ip vpn, we recommend that you use an IP/firewall function to enhance IPSec 56 or an IP/firewall to enhance IPSec 3DES. You can find a more detailed list of features and memory requirements for a given feature group in the
features to provide the highest level of security protection for enterprises that have deployed these IP communication solutions. Unlike other vendors that rely on gradually increasing single-point products to protect their communication solutions, Cisco's self-defense network-based multi-layer solutions start with the network itself, and all the way to the endpoints and applications. This comprehensive hierarchical security method is second to none in the industry. Customers can refer to the '

The rgmp protocol acts between multicast routers and switches. Rgmp allows you to fix multicast data packets forwarded by vsw
This article describes how to configure a vswitch for a CISCO 3550 router and how to configure access control for a MAC address.
In network management, users often encounter this situation: some users violate management regulations and modify their own IP addresses without permission to access restricted resources. Such behavior not only undermines information se
This article describes in detail how to configure a Cisco fixed IP address or PPPOE connection through network interface configuration and DHC matching value. For more information, see the following article.
Existing customers need to use cisco's 2600 router to access the Internet. The user is 10 m optical fiber and has applied for 16 fixed IP addresses, with the ip address 61.161.xxx.2-61.161.xxx.14. The d

EXEC mode. In Cisco IOS, this level is equivalent to having root permissions on UNIX or administrator permissions on Windows. In other words, you can fully control the vro.
Because the network is only maintained by a few people, each of them usually has a password to enter the privileged mode. However, in some cases, small or medium-sized companies will grow further, and permission issues will become more complex.
In many cases, the problem arises wh

, this IP address is only the first IP address in the DNS server response. If this is a large website with multiple servers such as a search engine), and the ACL only contains the first IP address that the DNS first responds to-you will have to manually block the remaining IP addresses. The following is an example:

This article describes in detail the basic introduction to the access security of CISCO Router network devices, and introduces basic security logon, terminal protection, authorization, and other issues, I believe that reading this article will help you.
To protect their Cisco networks, many administrators are busy with what traffic can be allowed to pass through
To protect their Cisco networks, many administrators are busy with what traffic can be allowed to pass through network devices, and how to restrict the unique information exchanged between mail route upgrades and other routers. The access control list (ACLs) usually solves these problems quite simply. The security of network devices is important to any networked environment. To solve this problem,
This document describes how to block access to a specific website. Taking Cisco Route 2600 as an example, we will provide detailed instructions.
There is a Cisco 2600 server, which is usually used as an Internet server. What should I do if I want to block certain websites?
This is not a difficult task-as long as you know how

What is the difference between an acl and a vacl between a cisco vlan, its implementation method is to apply the ACL directly to the virtual port of the VLAN, which is the same as the ACL implementation method applied to the physical port. The VLAN access control (VACL), also known as the VLAN access ing table, is implemented in a different way than the former. I
Implementation of ADSL access using the cisco 2500 router Description: This case is Beijing Telecom's adsl PPPoE access. A common adsl modem and a cisco 2500 router (dual Ethernet port) are required, and IOS 12.2 (15) t, can achieve LAN Internet sharing. in this case, the configuration is divided into seven steps: www.

The implementation of the Cisco SRP 500 system device has an illegal access vulnerability. You can create a required configuration file and upload it with an unverified URL, resulting in changes to the configuration of the device.
