The vswitch password modification technique leads to the master's kangzhuang Road. The technique of modifying the vro and vswitch password is discussed in three aspects: You can set the vro in five ways: the vswitch password modification procedure

The following articles describe in detail the problems of vswitch faults and other examples. For example, the heat they emit will affect each other and eventually lead to a serious reduction in their performance, the service life of the vswitch is

Enterprise Network security involves all aspects. For a vswitch, the first choice is to ensure the security of the switch port. In many enterprises, employees can use a hub or other tools to increase an Internet port to multiple, or use their own

The author uses floor switches to connect to an E-government intranet that is physically isolated from the Internet for online office work. Other units in the entire administrative building also use the same method, connect to the E-Government

Core layer switch common fault background The LAN of multiple branches directly accesses the CEN of the local headquarters through 10 m Fiber Channel of the local carrier. The networks of all local branches converge to the core layer switch, and the

As long as the Internet users who use the vro to access the Internet are experiencing network disconnection, this means that all computers cannot access the Internet. What should we do? Generally, this kind of connection is complicated. This

Offline data and remote users may overload your Wan egress. To prevent network overload, some WAN optimization solutions are available. Faced with the increasing network load, user scale, and real-time transmission applications in the data center,

The proliferation of Internet Worms has caused huge losses in recent years, which makes it a headache for many service operators and enterprise network administrators, in addition, the damage caused by attacks is becoming more and more serious.

Set the host name/system name on the IOS-based switch:Switch (config) # hostnameSet the host name/system name on the CLI-based switch:Switch (enable) set system name-string2. Set the logon password on the IOS-based switch:Switch (config) # enable

IOS Exchange Service1. Quick exchange2. Cisco fast forward3. Netflow exchange4. Multi-layer SwitchingOne of the following statementsQuick exchangeQuick exchange uses the notification cache item used for exchange to promote group conversion between

The jurisdictional distance is the source of route selection information, for example, the trust rate of a single vro or a group of vrouters. It is represented by a number, and the jurisdictional distance is 0 ~ An integer between 255. Generally,

This table mainly compares whether the vro is a modular structure. Vrouters with a modular structure are generally highly scalable and support multiple port types, such as Ethernet interfaces, Fast Ethernet interfaces, and high-speed serial ports.

The router can participate in the routing information domain by setting a password. In this way, OSPF packets can be verified. By default, the router uses null verification, that is, the exchange of route information through the network is not

1 OverviewTraditional VPN is usually built on the ATM/DDN/FR network. With the large-scale deployment of the IP network and the decline of ATM technology applications, providing VPN services on IP networks is considered a very economical method.

One reason for the huge success of the Internet is the simplicity of the IP protocol it uses. The Internet provides a best-effort service: the IP network tries its best to forward data packets from the source to the target, but does not make any

This article first introduces the overall structure of the ASON Control Plane, then compares GMPLS with MPLS, and finally focuses on the specific application of gmpls in the ason Control Plane. I. ASON Control Plane Overview 1. Reasons for

I. Introduction This article describes some basic guiding principles for using the debugging functions provided on the Cisco IOS (r) platform, as well as examples of correct use of the debug ip packet command and conditional debugging.Note: This

Vro is an important device for interconnection between the Intranet and the Internet. You can set static routes and dynamic routes based on network complexity. Static Routing can be easily configured for a simple network, but improper routing list

I. fault phenomena and handling The organization uses the Cisco7513 router as the WAN backbone router and adopts the standard configuration. The IOS version is 11.1. The 2 m main egress line protocol of the vro is found to be down on a single day,

In the Cisco router product series, only 7200 series, 7500 series, and 12000 Series GSR are supported. Generally, the names of IOS versions that support SSH include K3 or K4. K3 indicates 56bit SSH encryption, and K4 indicates 168bit SSH encryption.
