Cisco Catalyst Switch configuration and maintenance method. Today's Catalyst Switch topic discusses the introduction of the History st6000 series and the introduction of the Catalyst Switch 5000 Series. There is no difficulty. Hurry into the Wireless World. LAN switches have evolved from a HUB-based LAN shared in the t

loop monitoring function of the Ethernet 16 port, in the system view of the switch, enter the string command "interfaceGigabitEthernet1/0/16" and click the Enter key. After the switch is configured, the view status of port 16 on the Ethernet is displayed, at the same time, the command line prompt of the switch will automatically become "H3C-GigabitEthernet1/0/16

Cisco switch by default. But it can be implemented with only one command, namely: 3550 # terminal monitor. In order to experience the actual effect, we can open two DOS windows on our PC and log on to the same Cisco switch through TELNET. One is used for monitoring, and the other is used to perform specific operations, as shown below: for example, we execute a port shutdown and then no shutdown operation,

In a Cisco switch, how does one configure QOS speed limit? How to restrict BT download? This blog will use detailed examples for your explanation. Instance 1: QOS speed limit problem on CISCO switches It is used to control the bandwidth of a leased line user on a vswitch. The vswitch is usually at 10/100/1000 or three rates. QOS is required for other rates. You can also limit some ports, policy to restrict some ports. I. Network Description User‑pc1 i

The VTP password settings and Huawei switch vlan configuration experiment results show you how to configure the vlan of a Huawei switch. Many people may not understand the vlan configuration of a Huawei switch, VTP transparent mode, VTP password settings, and V1, v2 integrat

The core switch is still quite common, So I studied the TRUNK configuration function of the core switch. Here I will share it with you and hope it will be useful to you. What is TRUNK? What application advantages can TRUNK bring to us? How to configure the TRUNK in a specific core switch product? Let's take a look at t

The configurations of vrouters and vswitches of different models are also different. Therefore, in this learning, we need to learn a common method. Vswitch configuration has always been mysterious, not only for general users, but also for the vast majority of network administrators. It is also an important and basic indicator for measuring the level of network management. This is mainly due to two reasons: First, most of the vswitches configured by en

Switch STP Configuration The value range of the Spanning Tree priority is 0 ~ 61440, increment is 4096, its valid value is ,......, 61440. The smaller the priority value, the higher the priority. 0 is the highest, and 61440 is the lowest. When oneVswitchWhen the root port or blocked port of receives the inferior BPDUs package, it indicates that the indirect link from the

Because the portable computer is easy to carry, the configuration switch is usually done with a notebook computer, there is no notebook in the case, you can also use the desktop, but moving up some trouble. The local configuration of the switch is communicated by means of a direct connection between the computer and th

Network Device-Huawei-switch stack termination Configuration First, let's talk about the demand. In fact, in the case of medium and large IDC operators currently in contact with enterprise networking, many customers have high requirements on the early positioning and demand of redundancy solutions. Many of our competitors have outdated (mstp + vrrp) technical solutions and the most advanced virtualization s

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
