Overview of LAN switches
LAN switches have evolved from a HUB-based LAN shared in the traditional sense to a broader space. Take Cisco's Catalyst 5000 Series LAN switch as an example. It includes an integrated switching hardware structure, 10-Mbps Ethernet that supports switching, and-Mbps Fast Ethernet, supports fast Ethernet, FDDI, exchange-type ring, and layer-3 switching processing. This type of switch can provide exchange access to workstations, servers, network segments, backbone networks,
deciding on the wedding period (Love period ), including going out for dinner, buying gifts, entertainment, traveling, sending girlfriends holiday gifts to parents, etc. The average monthly price is 2000 RMB. for 2 years, the cost is 2000 × 12 × 2 = 4.8 W.
In summary, the total cost of each item is 64 + 15 + 8 + 12 + 3.0 + 4.8 = 103.8 million. The total cost is calculated as of the man's family's home income, and the annual income is (-30) /6 = 12 years. >>>

The IT Certification Examination Resources Network has collected a number of training materials for Cisco agents, including answers to pre-sales questions concerning routers, switches, IP/TV, firewalls, VPNs, network management, HFCs, VOIP, and equipment procurement., it can also be used as an entry-level document.12. Question: Which switches Does Cisco currently support layer-3 switching?Answer: Catalyst 2948G-L3, Catalyst 4908G-L3, Catalyst 4003, Catalyst 4006, Catalyst 5000, Catalyst
