CISCO 3550 vswitch DHCP configuration step 3

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

Configure access control for the MAC address of a vswitch on a Cisco 3550 Router

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

Switch: instance for VLAN configuration of Cisco L3 switch + L2 Switch

An instance of VLAN configuration for Cisco L3 switches and L2 SwitchesCisco VLAN implementation is usually port-centric. The port connected to the node determines the VLAN in which it resides. There are two ways to allocate a port to a VLAN: Static and Dynamic. The process of creating a static VLAN is to forcibly allocate the port to a VLAN. That is, we first create a VLAN on The VTP (VLAN Trunking Protocol) server, and then assign each port to the c
