For example, the following message only indicates that the isdn bri 0 interface is connected to a specific remote dat

information may be different. The Cisco IOS router supports adding the router identity information to the system log information, so that you can search for or separate information on the log server based on each device. This function is implemented using the logging origin-id command. For identity information, you can select the vro name configured using the ho

restart the vro, it does not retain this information. First, set your time zone and daylight saving time. Example:◆ Router (config) # clock timezone CST-6◆ Router (config) # clock summer-time CDT recurring◆ Then, in order to ensure that the router event message shows the correct time, set the router clock or configure

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 and a password to gain access. In addition, we

each entry, and rearrange the order of each access-list of the access list according to the matched number from large to small, which reduces the access-list of the message in the Access list. Reduce the time of specific packet lookup access list, reduce the burden of router CPU. It is important to note that the Access-list 100 uses the keyword "established" At the end, which is used by the Cisco

With the development of China's routing industry, its application is also more extensive, especially the application of routers and firewalls. Here we mainly explain the security configuration of NetEye firewall and Cisco router. Firewall has become a key part of enterprise network construction. However, many users think that Cisco routers already exist in the ne

I would like to introduce you to the Cisco Wireless Router setting method. Many people may not know how to optimize the Cisco wireless router settings. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. I. Basic

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

The OSPF protocol is very important for the use of Cisco routers. But how do I perform specific operations? The following article will give a detailed explanation. OSPF protocol operation: 1. the ROUTER that declares OSPF sends a HELLO message from all interfaces that start the OSPF protocol. The two routers share a Public Data Link and can negotiate with each other the parameters specified in their HELLO p

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 security rules, but may also cause network comm

Global debugging When configuring a Cisco router, the boundaries between global and interface commands are obvious. In this case, we use "Global" to identify commands that cannot be used for interface debugging or specific transmission media types and Protocol debugging. For example, in vrouters 2500, you can use Debugging commands to analyze the Cisco Discovery

There are many things worth learning about the configuration mode of a Cisco router. Here we mainly introduce the mode of user execution and privilege of a Cisco router. Ping is the most commonly used troubleshooting command. It consists of a group of ICMP response request packets. If the network runs normally, a group

Configuring a password for a Cisco router is a headache for common users. Here we will teach you how to configure a password for a Cisco router to bypass the vulnerability, cisco PIX, ASA, and FWSM are popular firewall devices that provide firewall services that can filter s

Cisco router has become a commonly used network device, but we are not very clear about its storage classification. Here we will introduce it in detail. Memory category: 1: RAM: Random Access to memory, equivalent to computer memory 2: ROM: read-only memory. Some microcodes used to start and maintain the router are resident in the ROM. 3: FLASH Memory, equiva
