cisco 3750 core switch

Cisco 3750 switch stack configuration points 3750 stack is a real stack, the Catalyst 3550 series uses StackWise technology, it is an innovative stack architecture, A 32 Gbps stack interconnection is provided to connect up to nine switches and integrate them into a unified, logical, and optimized device for convergence

, and the slot number is different) Iii. Stack instances: 1: The stacked cables are physically connected. The connection method is master stack1, which is connected to slave stack2. 2: enable the master without any configuration. . 3: Server Load balancer is enabled. 4: No configuration is required. Line plug, automatic stacking election upon startup, master is highlighted) Note: You can also configure stacks first, such as IP addresses and priorities. 4. Check the current stack status: Show pla

I will talk about two tips, one about monitoring switch port traffic and the other about store value. 1. Monitor switch port traffic Switch monitoring document in the production environment on the Internet. Therefore, it is complete, and a key knowledge is interspersed in the middle. Zabbix is still innocent .!!! In this demonstration, I used the production envir

CISCO 3750 Dual Switch stack operation, cisco3750 dual Double switch stack operation I. Basic Requirements: The ios version must be consistent with the dedicated stack module and stack cable, and the maximum number of stacks is 9. Ii. Stack advantages: High-density ports, easy to manage, and stacked switches can be reg

Learning Strategy Routing:Today to help friends of the company debugging a basic needs: the company's original 10M fiber network to provide staff access to the Internet, because the network behavior management is not very strict, speed when the speed is slow. Financial personnel every month need to report all kinds of reports on the Internet, seriously affecting the efficiency, hereby applied for an ADSL to financial room dedicated use.The original network structure is as follows: routing-

An instance of VLAN configuration for Cisco L3 switches and L2 SwitchesCisco VLAN implementation is usually port-centric. The port connected to the node determines the VLAN in which it resides. There are two ways to allocate a port to a VLAN: Static and Dynamic. The process of creating a static VLAN is to forcibly allocate the port to a VLAN. That is, we first create a VLAN on The VTP (VLAN Trunking Protocol) server, and then assign each port to the c

switch is a gigabit switch (all interfaces are gigabit)TT: Indicates that the gigabit on-connection port of the switch is base-t (i.e.: RJ45 interface)TC: Indicates that the switch gigabit on the port is dual-use, directly with the BASE-T, you can add modules on it.TS: Indicates that the 37

. Breakthrough Cisco switch cluster technology You can use the new Cisco switch cluster technology to achieve scalability and manageability beyond the stack. You can configure any Catalyst 3500 XL series or 2900 XL series standard or enterprise switch as a "command"

What is the Cisco switch module? The advanced traffic management feature in the Cisco switch module simplifies deployment and optimization of large networks, which allows many developers and users to extensively learn and study the principles of the Cisco

MAC address on the switch. In the middle of a Cisco switching network, how do I find out which port of the switch is connected to the IP address of a machine? The most convenient and quick way is to use the User tracking function of the CiscoWorks 2000 LMS network management software. The graphical interface is clear at a glance. If you do not have this software

Speaking of Cisco's switch upgrades, most people think of the following steps:(1) Upload the system. bin file to the switch via TFTP or FTP(2) Delete the original. bin file, reboot (or manually set the boot order)(3) upgrade completed after reboot.Indeed, 2960, 3560, 3750 and so on switch upgrades can be done through t

there are many cables on the switch. With the naked eye, it is difficult to accurately identify idle ports at once (if an error is accidentally pulled, the Network may fail). Therefore, we used to log on to the switch, run the following command: 3550 # show inter. At this time, the switch will display the details of each port in sequence, including the port disc

Cisco is the main force in the entire vswitch. Its products are doing very well in the market. The following article will detail some of the usage skills and precautions of Cisco switches, in many organizations, the core backbone switches are primarily Cisco. In the process of debugging and maintaining

the current market, any port with a transmission rate of Mbps is referred to as a cisco Gigabit Switch. For example, most mainstream products currently provide 10/100/100/1000 Mbps adaptive and 10/100 Mbps adaptive ports, Mbps ports are provided to desktop users, and Mbps ports are used for core switching. In fact, there are not many products with a single Mbps

DDoS attacks. VLAN A virtual LAN is an essential security feature of cisco switches. A VLAN can implement a limited broadcast domain on a layer-2 or layer-3 switch. It can divide the network into independent areas and control whether these areas can communicate. A VLAN may span one or more switches. It is independent of their physical locations, and devices communicate with each other in the same network.
