cisco catalyst 3550

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

/17 Cisco (config-if) # ip access-group 6 in Cisco (config) # access-list 6 permit 10.138.208.81 In this way, the FastEthernet0/17 port of the vswitch is bound to ip Address: 10.138.208.81. 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

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 3550 as

The following are the modules supported by vswitch 4500: WS-F4531-Cisco Catalyst 4500 NetFlow service daughter WS-X4148-FE-LX-MT-Cisco Catalyst 4500 Fast Ethernet Switching Module, 48 Port 100BASE-LX10 Single-Mode Optical Fiber SMF) MT-RJ) WS-X4148-FX-MT-Cisco

a very important application, which will prompt the IT team to rethink the Network Design of San Jose headquarters. Network convergence-transmitting data and voice over the same network-will save Cisco's long-term expenditure and serve as a platform for future development. However, in the short term, it will put heavy pressure on a diverse platform that forms the Cisco network infrastructure. Cisco

Cisco Catalyst Switch configuration and maintenance method. Today's Catalyst Switch topic discusses the introduction of the History st6000 series and the introduction of the Catalyst Switch 5000 Series. There is no difficulty. Hurry into the Wireless World.

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

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.
