The client can specify the IP address at will.The client does not have to use the DHCP service. It can set IP addresses in a static way. If any,This will greatly increase the possibility of network IP address conflict.II. Introduction to DHCP Snooping TechnologyDHCP Snooping is a DHCP security feature. Cisco s

There are two groups of Group1 and Group2 in the environment, respectively, to access the Internet from two different network outlets. 2. The core network is a Cisco 3560G layer-3 Switch with four VLA

When I got up this morning to go to the forum, I saw a post. Ask how to solve the following problem? A Cisco three-tier switch divides 3 VLANsVLAN 2:IP 192.168.1.1 255.255.255.0 192.168.1.254 Network SegmentVLAN 3:IP 192.168.2.1 255.255.255.0 192.168.2.254VLAN 4 IP 192.168.3.1 255.255.255.0 192.168.3.254Each VLAN can communicate with each other.Now add 1 Cisco r

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

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

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

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
