The Cisco router switch sets automatic backup for IOS files and restores the automatic backup and rollback of Cisco IOS configuration files. The archive configuration mode function of IOS is required. Generally, only IOS versions 12.3 (4) All commands for automatic backup of the Cisco IOS configuration file are as foll

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

message are correctIf a large number of messages are sent, the network bandwidth will be exhausted to form another Denial-of-Service attack.3. 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

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

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
