to say, after you set the password for level 1, you will be asked to enter the password next time you connect to the switch and enter K, this password is the password set for level 1. Level 15 is the privileged mode password that you enter after you enter the enable command.
Step 2: Set the VLAN name. Because the four VLANs belong to different switches, the command for VLAN naming is VLAN 'vlan No. 'name' vlan name ', the following code configures VL
When configuring the Cisco 3560 switch in the morning with the Cisco Packet Tracer practice, it is found that the IP address of the port cannot be configured in port configuration mode.Switch>Switch>enableSwitch#configure TerminalSwitch (config) #interface F0/1Switch (config-if) #?DhcpOnly DHCP commands are available.
We have explained a lot about the configurations of CISCO switches. Here we will mainly explain the port security configurations of CISCO 3550 switches. Scenario: There is a CISCO3550 switch in a certain unit. For the sake of network security, the security requirements for some ports are high, that is, only the specified host can be connected, for example, if you
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.

It may take 30 seconds or more to connect a computer to a vswitch before the computer can communicate over the network. If you are waiting for a long time, 30 seconds of waiting will make you feel very long. Let's take a look at how to accelerate the port initialization process of the switch.Understanding the process of vswitch port InitializationWhen a device is connected to the port of a started switch, the swit
The IT Certification Examination Resources Network has collected a number of training materials for Cisco agents, including answers to pre-sales questions concerning routers, switches, IP/TV, firewalls, VPNs, network management, HFCs, VOIP, and equipment procurement., it can also be used as an entry-level document.12. Question: Which switches Does Cisco currently support layer-3 switching?Answer: Catalyst 2
want to initialize the switch, you need to enter the Privileged EXEC mode. Enter setup in the command prompt symbol to start the initialization operation.The Privileged EXEC mode is introduced just now. In this case, we need to talk about several modes of machine change. Different modes can execute different operation commands. First, we need to talk about two basic modes.For the sake of security, CISCO di

[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
In many cases, we may need to log on to the Cisco switch to execute some common viewing commands, but it is troublesome to run cmd, enter the password, and enter the command.
