The difference of the Cisco Catalyst 2900 and Cisco Catalyst 1900

Question: The Cisco 2900 series and Cisco 1900 series

The Cisco Catalyst 2900 ws-c2960g-8tc-l and Cisco Catalyst 1900 are Cisco low-end products, what's the difference between them, and what models contact?

Answer:　Desktop computer access switch 1900 is suitable for the network terminal, is a typical low end products. It offers 12 or 24 10M ports and 2 100M ports, 100M ports support full duplexcommunication, and can provide up to 200Mbps port bandwidth. Backplane bandwidth of the machine is 320Mbps.

With 1900 enterprise edition software also supports VLAN and ISL Trunking, up to 4 VLAN,but in general, not many low-end product to request this function.

1900

1900 some models of fiber with 100BaseFX interface. As C 1912C, C 1924C with a fast Tx port and a fast Fx port, C 1924F with two 100BaseFX interface. The main model 1900 seriesas follows:

C1912: 12 10BaseTx, 2 100BaseTx, 1 AUI port

C 1912C: 12 10BaseTx, 1 100BaseTx, 1 AUI ports, 1 100BaseFx ports

C1924: 24 10BaseTx, 2 100BaseTx, 1 AUI port

C 1924C: 24 10BaseTx, 1 100BaseTx, 1 AUI ports, 1 100BaseFx ports

C 1924F: 24 10BaseTx, 1 AUI ports, 1 100BaseFx ports

If in your network, some of the desktop computer is 100M, then the 2900 series may be moresuitable for. Compared with 1900, 2900 the biggest characteristics is the speed increase, the backplane speed it up to 3.2G, up to 24 10/ 100M adaptive port, all ports support full duplexcommunication, make the desktop access speed is greatly improved. In addition to port rate,many other properties of 2900 more than 1900 series have been significantly improved. For example, 2900 of the MAC address table size is 16K, can be divided into 1024 VLAN, support for ISL Trunking protocol.

2900

2900 series of product line is very long. Among them, some are the common 10/100BaseTxswitches, such as C2912, C2924 etc.; some are with an optical fiber interface, such as C2924C with two 100BaseFx port; some are modular, such as C 2924M with two expansion slots. Expansion slot card can be placed 100BaseTx module, 100baseFx module, ATM module and can be inserted and Gigabit Ethernet interface card (GBIC). The details are as follows:

C2912-XL: 12 10/100BaseTx adaptive

C2912MF-XL: 2 expansion slots, 12 port 100BaseFX

C2924-XL: 24 10/100BaseTX adaptive

C 2924C -XL: 22 10/100BaseTX adaptive, 2 port 100BaseFX

C 2924M -XL: 2 expansion slots, 24 adaptive 10/100BaseTx

In the 2900 series, two products unique, one is C 2948G, two C 2948G -L3. The performance price ratio of 2948G is also good, it uses the software and Catalyst 5000/5500,48 10/100Mbps adaptive Ethernet port and 2 Gigabit Ethernet ports, 24G backplane bandwidth, with redundant power supply hot swap, a series of fault tolerant characteristics and management characteristics. C 2948G -L3 increased the capacity of three layer switchbased on C 2948G, a maximum of three layer packet throughput of up to 10Mpps. However,in general, the low-end 2900 series switches are generally used in network capacity, ws-c3560x-24t-e Gigabitand routing is not very important, so the two section 2948 in the actual use of the projecthave not.
