System Switch Machine commandDescription-The server does not shut down frequently, restarts, does not fail, and the server does not shut down. So these commands don't seem to be very common.1, Shutdown/usr/sbin/shutdowne.g.Shutdown-h 0# shuts down immediately , but it is best not to use this command on the server.2, Reboot/usr/sbin/reboote.g.Reboot system restart

The use of the SNMP protocol in switches I'm sure you're not unfamiliar, so let's go over 5 basic switch SNMP configuration commands in detail. The completion of the switch SNMP configuration commands is a common problem, how to complete the

Previous page Everyone talked about Cisco Basic Operation command switch, while dragon boat holiday, the Cisco simple switch configuration, and hope you share "Happy Dragon Boat Festival"! Ok, configure the switch, first, you must enter the global configuration mode

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

Technical standards for VLANs IEEE 802.1Q was formally promulgated by IEEE Commissioners in June 1999, and the earliest Vlna technology was proposed by Cisco (Cisco) companies in 1996. With the development of the past few years, VLAN technology has been widely used in large and small enterprise networks, becoming the most popular Ethernet LAN technology at present. This article is going to introduce one of

/17 Cisco (config-if) # ip access-group 6 in Cisco (config) # access-list 6 permit 10.138.208.81 In this way, the FastEthernet0/17 port of the vswitch is bound to ip Address: 10.138.208.81. The most common understanding of port security is to control and manage network traffic based on the MAC address, such as binding a MAC address to a specific port, rest

Basic Maintenance for the Catalyst6000 series and the Catalyst5000 Series The ipvst6000 series and ipvst5000 series Cisco LAN switches provide powerful functions, including many usage and maintenance commands. Below are several

Cisco is now the world's largest manufacturer of switching routes! Many of our businesses, large and small, can use the network, and it is possible to switch routes to Cisco! When we install network equipment, we may ask the network engineer to help us install it! Access to the router has a lot of passwords! What if we forget these passwords? We may have to make

Cisco switch by default. But it can be implemented with only one command, namely: 3550 # terminal monitor. In order to experience the actual effect, we can open two DOS windows on our PC and log on to the same Cisco switch through TELNET. One is used for monitoring, and the other is used to perform specific operations
