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
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.

I will talk about two tips, one about monitoring switch port traffic and the other about store value.
1. Monitor switch port traffic

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

2. Define Access Control List
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:

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!
