cisco 3750 48 port switch

I will talk about two tips, one about monitoring switch port traffic and the other about store value. 1. Monitor switch port traffic Switch monitoring document in the production environment on the Internet. Therefore, it is complete, and a key knowledge is interspersed in th

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 1. Start QoS on the switch Switch (config) #mls QoS//Start QoS on the switch 2. Define Access Control List

Cisco 3750 switch stack configuration points 3750 stack is a real stack, the Catalyst 3550 series uses StackWise technology, it is an innovative stack architecture, A 32 Gbps stack interconnection is provided to connect up to nine switches and integrate them into a unified, logical, and optimized device for convergence

, and the slot number is different) Iii. Stack instances: 1: The stacked cables are physically connected. The connection method is master stack1, which is connected to slave stack2. 2: enable the master without any configuration. . 3: Server Load balancer is enabled. 4: No configuration is required. Line plug, automatic stacking election upon startup, master is highlighted) Note: You can also configure stacks first, such as IP addresses and priorities. 4. Check the current stack status: Show pla

Basic Requirements: The ios version must be consistent with the dedicated stack module and stack cable, and the maximum number of stacks is 9. Ii.

Common commands:Restart a switch: Reload slot If you want to modify the number of the two switches, you can use the following command, restart after the effective:switch (config) #switch 1 Renumber 3 change the number of switch 1 to 3switch (config) #switch 2

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. Cisco

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

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

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.

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

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

More and more cases require Port Security recently. Port security is mainly used to restrict access to port access by binding a client Mac. The ACL between VLANs is not in the current range. After several days of practical debugging, I learned from the experiences of my predecessors and summarized my debugging experiences as follows: 1. cisco29 series switc

As the core network switch of our company, the CISCO3550 has been running stably for many years, and its functions can also meet our needs. However, its port speed limit function is not as easy to implement as some other switches, fortunately, the implementation method has been found recently. After the configuration is complete, it is verified with the iperf software. The result shows that this method is e

For many enterprise network administrators, switches are naturally the most commonly used equipment. So how much do you know about vswitches? Next we will use an example to discuss the practice of vswitch port configuration and access security protection! 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, on
