LAN is not changed, and the configuration and access control list of the external network Port WAN needs to be changed .Increase the configuration of the VPDN. Assuming the username is admin, password 123456, the configuration process is as follows:This case is XX Telecom ADSL PPPoE access, need to use a common ADSL modem and a Cisco 2600 router (dual Ethernet port), IOS 12.2 (), can realize LAN sharing Internet. This case configuration is divided i
Tags: process proc ima RAC Technology share static term ADOBy configuring static routes, you can achieve an increase in routing entries for routers in a relatively simple network.However, if there are more than 20 routers in a network, it is difficult to configure static routes to accommodate the complexity of routing entries and changes in the network. At this point we can use the RIP protocol to configure simple dynamic routing, thus reducing the workload.Configuration ideas1 Configure the IP

The server setting of the Cisco router log is a high-end problem. In the process of using it, we need to constantly find a better way, but for linux, many people are not very clear about it. How does one set linux to a Cisco router log server? To achieve unified log management, including 2950 6509 3550 2611 and Huawei 3526 switches.Method 1: QUOTE: RedHat: vi/etc

In DHCP settings, we usually work with routers. Here we will introduce the debugging and settings of Cisco routers and DHCP. A company uses Cisco 3620 as the ios dhcp Server. the IP address of the fastethernet0 port connected to the Intranet is 192.168.1.4. The L2 Switch uses two Cisco 2950 and the L3 switch uses a Cisco
I came back again, the last two articles introduced the Huawei Stack, third firewall IRF. This time to introduce the Cisco stack (stack), although the implementation of the idea is consistent, but the configuration there is a need to pay attention to the place, especially now do the two-tier operators of the network workers, all the producers will be, the pressure is really big.First, the topological environment:650) this.width=650; "Src=" Http://s2.5
We have explained a lot about the configurations of CISCO switches. Here we will mainly explain the port security configurations of CISCO 3550 switches. Scenario: There is a CISCO3550 switch in a certain unit. For the sake of network security, the security requirements for some ports are high, that is, only the specified host can be connected, for example, if you
Set an instance for SSH on a Cisco device Http://www.pcdog.com unknown When using telnet for remote device maintenance, SSH should be used instead of Telnet because passwords and communications are in plain text and are easily listened by sniffer.

A unit uses 3640 as the iOS DHCP Server, and the IP address of the FASTETHERNET0 port connected to the intranet is 192.168.1.4, the second-tier machine uses two 2950, the three-tier machine uses a Cisco 3550. There are two VLANs throughout the network, for a simplified description, assuming that each VLAN has a 24-bit network address, where the IP address of the VLAN1 is 192.168.1.254,vlan2 192.168.2.254.

generally not the case, we can find the answer we need by executing corresponding commands on the vswitch. I used the show inter command in the past, but this command displays too much information, which seems inconvenient. Now I am using the show inter status Command, this command displays the disconnected status of each port one by one (expressed by "connected" and "notconnect ), in this example, I found an idle Port 3 through this command for subsequent testing.
Vswitch span technology Overview + Cisco configuration example 1. Introduction to span The span technology is mainly used to monitor data streams on vswitches. It can be divided into two types: Local span and remote span.---- Local Switched Port Analyzer (SPAN) and remote span (rspan) have slightly different implementation methods. Using the span technology, we can copy data streams or mirror 1 on some vswitches that want to be monitored ports (herein
One of my customers has a VPN which I 'd like to access. they provided me with a copy of the Cisco VPN Client for Linux, and a "PCF" configuration file for the client. here's what I had to do to get the Cisco VPN Client working in Linux-and it does work just fine.

IOS is the core of a vro switch device, and IOS is internet operate system. It is like a computer's operating system windows. Although it is a software, it cannot run any software if it encounters a problem. Therefore, if there is a problem with IOS, the routing switch device will not be able to run normally, and the configuration commands will all be lost. We can only reinstall IOS.
