how to configure vlan on cisco switch

Layer-3 Switch for Cisco switches Although single-arm routing solves the communication problem between different VLANs, it also has its fatal defects: -The single arm itself is the Backbone link of the network, which is easy to form a network bottleneck. -The sub-interface relies on physical interfaces, and the application is not flexible -You need to view the route table for each

describes the products of these series: 1. Low-end products Let's talk about low-end products. 1900 and 2900 are typical low-end products. In fact, Cisco does not take a special advantage in the low-end switch market, because 3Com, Dlink and other companies have better performance and price ratios. The 1900 vswitch is a typical low-end product for desktop computer access at the end of the network. It provi

routing sub-card of the super engine on MSFC 6000 provides 15 Mpps L3 forwarding IP addresses and IPX packet forwarding capabilities. It works with the PFC card to provide IP multicast capabilities. The PFC card is used to provide layer-3 functions for vswitches, such as VLAN access list control and QOS access list. MSFC is not required to install the PFC card, but you must install the PFC when installing MSFC. C
