24-port full-Gigabit Switch forwarding performance and line-end congestion tests. The current 24-port full-Gigabit Switch market is in great competition, some may not know the forwarding Performance Test and line congestion test o
lower priority are treated differently from those with a lower priority.The test method is to send data frames from three ports to 4th ports at the same time. Each port starts from 30% of the load, and then increases by 10% each time until 100% of each port, causing congestion, view the results of processing data fram
SNMP, POP3, and HTTP data streams that simulate UDP ports 161,110 and 80 to ports 4 at the same time.
The priority of the three data packets is the highest in the 24-port full Gigabit Switch, the highest in SNMP, the lowest in POP3, and the lowest in HTTP. The traffic on the three ports starts from 30% of the load and sends data packets to the congestion
tags. Each 24-port full-gigabit switch enables the port priority. Then, we will observe the results of the 24-port full-gigabit switch processing different priority packets.

Ethernet switches are still commonly used, so I studied the high availability of stack 10/100 Ethernet switches. I would like to share with you here, hoping to be useful to you. Catalyst3524-PWRXL Ethernet switches are part of the CiscoSystemsCatalyst3500XL series, which is a series of scalable stack 10/100 and Gigabit
The implementation of the multi-port Cisco switch module is a common problem. How to configure the Cisco switch module, any problems related to ports will be fully resolved in this article.

In the middle of a Cisco switching network, how do I find out which port of the switch is connected to the IP address of a machine? The most convenient and quick way is to use the User tracking function of the CiscoWorks 2000 LMS network management software. The graphical interface is clear at a glance.
If you do not have this software, you can use the following
There are many things worth learning about the 24-port switch. Here we will mainly introduce the detailed descriptions of the various parameters of the 24-port switch. In network equipment, the
The most widely used switch for small and medium-sized enterprises is the 24-port Gigabit Switch. Therefore, when purchasing a switch, you must make full consideration. A clear purpose is to save costs for everyone. In network equipment, switches may be the most familiar dev
Port security Configuration for the Cisco PT Simulation Experiment (7) switchExperimental Purpose : Master the port security function of the switch, control the user's secure accessExperimental Background : The company network adopts the personal fixed IP Internet program, in order to prevent the company internal User
Cisco switch port broadcast storm settings are more practical. When a port receives a large number of broadcast, unicast, Or multicast packets, a broadcast storm occurs. Forwarding these packets will slow down the network or cause timeout. Using broadcast storm control on ports can effectively avoid network paralysis c
When selecting a 24-port Gigabit Switch, we need to consider the number of its Mbit/s and Gbit/s ports, and then we can know the bandwidth value of its backboard. In network equipment, switches may be the most familiar equipment for network administrators, especially access layer switches. However, when purchasing switches, many brands seem to have identical tech
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 specifi
I will talk about two tips, one about monitoring switch port traffic and the other about store value.
1. Monitor switch port traffic

GE switches are still commonly used. So I studied how to increase the speed of a 24-port Ge switch in a large area. Here I will share with you, hoping to help you. With the emergence of Ge-switched network applications, large file transmission and game applications such as high-end multimedia and CAD have gradually increased, many users want to achieve high-speed
generally not the case, we can find the answer we need by executing corresponding commands on the vswitch. I used the show inter command in the past, but this command displays too much information, which seems inconvenient. Now I am using the show inter status Command, this command displays the disconnected status of each port one by one (expressed by "connected" and "notconnect ), in this example, I found an idle
The port rate between switches and switches, between switches and routers, does not meet the actual rate and requires tying more than two ports together to load balance and prevent single points of failure.1.

Note: Each interface supports only one policy, and one policy can be used for multiple interfaces. Therefore, the download rate limit for the network segment under the port should be defined in the same policy
