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

Cisco port status: CSU ── channel server unit, DSU ── data server, unit, DTE ── DataTerminalEquipment 1. Serial * is down, line protocol is down (DTE) faults: [1] No power is added to the vro. [2] LINE is not connected to CSU/DSU. [3] hardware error. Solution: [1] Check power supply. [2] Check whether the cables and serial ports used are correct. [3] switch to another serial

In order to manage a network, the network grasping the packet Analyzer is essential, but now is no longer the hub era, grab bag is not so easy, but there is always a way to mirror the port, the other port data copy to the port you specify, so you can grab the bag. Today is not about grabbing bags, It is mainly about how to configure the

Steps:1 , the configuration of the Cisco switch Create a new link aggregation channel port in privileged mode and add the port to the Vlansw2960 ( config ) #intport-channel 1 ( Span style= "Font-size:14px;color: #3F3F3F;" > According to the actual situation fill in channel sw2960 ( Config ) #switchport Access Valn Configure the ports to join the link

RGMP: Cisco router port group management protocol (rgmp) makes up for the Internet group management protocol (Igmp: Internet group management protocol) problems in snoopIng technical mechanisms. The rgmp protocol acts between multicast routers and switches. Rgmp allows you to fix multicast data packets forwarded by vswitches in the required vro. Rgmp is designed for backbone swItched networks, which is conn

The core switch is an all-optical fiber switch of beidian. On one of the floors, some applications need to be implemented. cisco 3560 is selected, and Port 1 is connected to the network cable transferred from the photoelectric converter, however, if the first port is normal for about 2 seconds, it turns yellow and network communication is interrupted. If you conn

We all know that the port of the switch is more, when you want to see some port status (is in the up or down state), we usually use the following command:Cisco: Show Interface XH3c:display Interface XNote: The X-form port number, such as E1/0/1.But if the port of the switch is very long, and you want to know the status

Ciscoportfast This is for the access port, a normal switching interface from down to up to pass: Down,listening,learning,fowarding Several states, total time is 30 seconds, This determines whether this port is blocking or fowarding and is also a mechanism for the switch to prevent loops. However, for direct access to such terminal equipment interface is not necessary to go through these steps, that is, from

The port Mapping method enables access to specific port services from the Internet to the local area network internal machines. For example, the machine you are using is in a LAN connected to the Internet, all the services you open on the machine (such as FTP), by default, the outside world can not access. This is because your IP is the LAN internal IP, and the outside can access only the server you are con

Cisco 3560 vswitch Port Speed Limit1. The network indicates that PC1 is connected to Cisco3550 F0/1 at a rate of 1 M. PC1 is connected to Cisco3550 F0/2 at a rate of 2 M. The G0/1 of Cisco3550 is the egress. Ii. Detailed configuration process Note: Each interface supports only one policy in each direction. One policy can be used for multiple interfaces. Therefore, the download speed limit of all PCs should
