Figure Cisco Catalyst 3550 series smart Ethernet switches are a new type of enterprise-class stackable multi-layer switch that provides high availability, high scalability, and high security, and improves the management capabilities of network operations. With a series of Fast Ethernet and Gigabit Ethernet configurations, the Catalyst

For details about how to configure DHCP for a CISCO 3550 switch, refer to some configuration content in this article for comparison and learning. After "ip helper-address dhcp server ADDRESS" according to the configuration described on the Internet, the project finds that the client cannot obtain the ip address from the DHCP server, I recently configured

This article describes how to configure a vswitch for a CISCO 3550 router and how to configure access control for a MAC address. In network management, users often encounter this situation: some users violate management regulations and modify their own IP addresses without permission to access restricted resources. Such behavior not only undermines information security rules, but may also cause network comm

Lab Environment:1. Configure two VLAN 10 and VLAN 20VLAN IP address settings: 192.168.10.1 255.255.255.0 (192.168.10.1 is a VLAN 10 gateway address)VLAN IP Address setting: 192.168.20.1 255.255.255.0 (192.168.20.1 is a VLAN 20 gateway address)2. (Windows Server R2 operating system) set up a DHCP server to create two scopes VLAN 10 and VLAN 20,Get the IP address dynamically using VLAN 10 and VLAN 20. The DHCP server NIC accesses the switch FA0/1 port.D

In Cisco 3550, dhcp configuration is often discussed on the network, but there are mostly errors and omissions. According to the configuration described on the internet, after "ip helper-address dhcp server ADDRESS, in the project, I found that the client could not obtain the IP address from the DHCP server. I recently configured 3550 as the DHCP server relay pro

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, restrict the number of MAC addresses that a speci

Cisco switch iOS upgrade, actually quite simple, but need to note is, can not let the switch flash storage is empty, must have an iOS in, or no iOS in Flash, waiting to upload iOS with Xmodem, so your time can be a lot of waste ah.
