juniper switch configuration

constructs a loop-free path to the root bridge for all the bridges in the network. When spanning tree convergence is complete, each bridge in the network will be one of two states for its bridged port: forwarding or blocking. STP determines the topology of a network by passing a special protocol message (BPDU) between the switches. the BPDUs contain enough information to ensure that the switch completes the spanning tree calculation. The STP protocol

Super [command] super [level] [view] www.2cto.com user view [Default level] 0: access level [parameter] level: user level, value Range: 0 ~ 3. The default value is 3. [Description] The super command is used to switch the user from the current level to the specified level. 1-9 if the level parameter is not specified when using this command, the user will switch from the current level to level 3. User level r

The Catalyst3550 switch with EMI supports three routes or bridged three-tier interfaces: Svis: You should configure Svis for any VLAN you want to route traffic to. When you enter a VLAN ID after the interface VLAN Global Configuration command, the Svis is created. To delete a SVI, use the command: (global) No interface VLAN You need to assign a two-tier port to VLANs, see "Configuring VLANs". Three-lay

I have just been familiar with the basic configurations of the VLAN division experiment of the switch VLAN division configuration (PT simulator). I am not familiar with this knowledge for too long. Please forgive me for any errors, this configuration is for you to learn about the Cisco simulator configuration case. Www

In the previous article, we have explained the DHCP Server settings and DHCP Relay settings of the H3C switch. Here we will explain the last part -- DHCP Snooping configuration of the H3C switch. H3C switch DHCP Snooping configuration 1> Configure Environment Parameters 1. T

1 , what is the privileged mode of the switch? There are 6 modes of the switch. 1: The user execution mode (userexecmode). 2 : Privileged Execution Mode ( privilegedexec Mode ). 3 : Global configuration mode ( globalconfiguration Mode ). 4 : Monitor mode ( ROM Monitormode ). 5 : Safe Mode ( Setupmode ). 6 : Boot Mode ( Rxbootmode ). commonly used to have the a

A three or four-day shift was added. Finally, the three-layer switch has been taken care of. The previous touch was a fool. (Huawei's technical support attitude is not very good), The configuration environment and configuration files are as follows: Environment, dual-WAN port routing access to ADSL, the next to the Huawei S3928p-si do core switches. The

example, a 24-port Mbit/s switch, the backboard bandwidth should be 24x2x100 MB = 4.8 GB. If the switching capability of a vswitch is greater than the bandwidth calculated using the above formula, the switch is usually configured with an expansion slot, and the excess switching capability is prepared for the expansion module.● FunctionsThere are many types of vswitches on the market, which can be divided i

What exactly is trunk? What are the advantages of using the trunk function to us in the application? And how to switch trunk configuration in a specific switch product, let's take a look at these areas of knowledge. In the performance parameters of the two-tier switch. often mentions an important metric: TRUNK, many

If you have configured a name for the vswitch, you can enter the name of the vswitch directly with a blank space after the "Telnet" command. After reading this article, you must have learned a lot, I hope this article will teach you more things. Run the Telnet client program on the computer. This program is available in Windows and UNIX and Linux systems, and its usage is basically compatible, especially in Windows ), and log on to the remote switch.

. Authentication Sever can adopt standard Radius Authentication Server or service switch. The latter is mainly used in scenarios with a small network size (about 300 users, in the new software version, the Quidway 3000 and later vswitches of Huawei 3Com all provide the built-in Authentication Sever function, the user authentication configuration function is efficiently completed through the internal cluster

Example of RADIUS authentication, authorization, and billing configuration for 18.6.3 802.1x users In 802.1x authentication, the use of remote RADIUS servers is the most commonly used AAA access control, and the RADIUS server can not only realize the required authentication of 802.1x users, but also authorize and charge them. This example topology, as shown in Figure 18-6, uses a RADIUS server that is widely used by the H3C company to develop the IMC

All VLANs allowed by the RRPP port should be protected by the RRPP domain. 3, RRPP under the port do not allow control VLAN through. 4, RRPP in STP domain to the Control VLAN to join the domain. "Experimental Software and Topology" ENSP 1.0 simulator, praise, this simulator is really good! Have not been how to contact before, use up quite conveniently, and the real environment is similar.

Overview of LAN switches LAN switches have evolved from a HUB-based LAN shared in the traditional sense to a broader space. Take Cisco's Catalyst 5000 Series LAN switch as an example. It includes an integrated switching hardware structure, 10-Mbps Ethernet that supports switching, and-Mbps Fast Ethernet, supports fast Ethernet, FDDI, exchange-type ring, and layer-3 switching processing. This type of switch
