Microsoft's Windows Server 2012 has been able to support LACP link aggregation, due to the use of link aggregation can achieve line redundancy and bandwidth increase, here I used a Cisco 2960 to do a test for interested friends reference.Experiment Preparation:Cisco switch 29,601, install server 2012 servers, there are two Gigabit network card, network cable two root.Steps:1. Configuration of

The company has several switches need to initialize the configuration, here the process, for you to reference. This initialization process only tests the Cisco 2960 and 3550 Series switches, and the method is available. Thank you for the help in the test the little man Tang was flying. One: Know the switch privileged password in case If you know the privileged password for the

After the FLASH space is insufficient, I specially query the hardware configuration of the 6509 core device. The default Flash of the 6509 standard configuration is 64 MB, and the standard IOS size is 32.1 MB, the IOS 12.2 (17a) SX version to be upgraded has a size of 40.6 MB. In this case, it seems that the space is insufficient. However, this problem is well solved. The original IOS in Flash is deleted and then uploaded. So enter the command: Router

Cisco switches enable port speed limiting As shown in, Node switch 3550 is placed in an office room. The networks of all office companies are from this place. How does the operator configure network bandwidth settings for each company on this device? Let's take the IT Training Center of XX foreign companies as an example. The IT Training Center of XX foreign companies applied for a 2 m link. Step-1 Rongxi

[Cisco] DHCP relay, layer-3 Switch VLAN Routing PracticeThe experiment topology uses the GNS3 0.8.6 simulator to build a DHCP server using Red Hat 6.5. The experiment requires configuring a layer-3 Switch VLAN routing so that VLAN10 and VLAN20 members can access each other. Performs DHCP relay for layer-3 switches so that VLAN10 and VLAN20 members can obtain IP a

A Dell machine with a network card of M is connected to a Cisco switch. The error err-disabled occurs because of link-flap, that is, the network card is up and down too frequently in a short time. This error is not returned when a vswitch interface is changed. The cause is unknown.

displayed. Some people think that this Cisco router mode is useless because configuration changes cannot be made in this mode, and users cannot view any important information. 2. Privileged mode router # administrators can view and change configurations in this mode. I believe that it is absolutely important to have a set of passwords at this level. To switch from user mode to privileged mode, the administ

In Cisco command configuration tip 1, we talked about using the Range Command to simplify our configuration. However, if we often operate on a group of discontinuous ports Such as interface-range fa1/1, fa1/3, fa1/5, fa1/7, fa1/11 Even using the Range Command is cumbersome. We always think that the simpler

configure and update each switch, because this time-consuming and laborious method hinders the development of enterprise networks, this has attracted the attention of the industry, so some new technologies have changed. For example, the first generation of stacked switches that emerged in 1996 allows network administrators to manage multiple switches as a logical group on the console and solve the scalability of the system. Of course, the first gener

Q: Are there any simple tools and methods? Run the script automatically on N or so cisco switches according to the script, and then return the result?Method 1: Download and modify the vswitch configuration file and upload it to N vswitches. Restart or copy start run.Method 2: Create a bat file under windows. The content in the file is the same as the command you used to telnet to the vswitch for modificatio
