To select a cisco Gigabit Switch, refer to vlan support.

To select a cisco Gigabit Switch, You need to refer to vlan support. The choice of a cisco Gigabit Switch is a common problem. To measure the cisco Gigabit Switch, you need to pay attention to after-sales service and vlan support, MAC address count and other factors.

Vlan support

Vlan is a virtual LAN. Through vlan support, it can prevent the LAN from generating broadcast effects and enhance management and security between network segments. Different cisco Gigabit Switches support different VLANs, the number of supporting VLANs is also different, for example, cisco WS-C6509 supports 1000 VLANs, and Lenovo tiangai iSpirit3508G-L3 supports 64 VLANs. Most cisco Gigabit Switches now support port-based, IP-and MAC-based, and multicast-based VLANs.

MAC address count

MAC address count refers to the maximum number of MAC addresses that can be stored in the MAC address table of a cisco Gigabit Switch. The more MAC addresses are supported, the higher the data forwarding rate. Generally, a cisco Gigabit Switch can have more than 4 k MAC addresses, such as 6 k, 8 k, 16 k, and 32 k. The larger the number of supported MAC addresses, the higher the general price. We recommend that you select a cisco Gigabit Switch with 16 k mac addresses.

After-sales service

Because cisco Gigabit Switches differ greatly from common cisco Gigabit Switches in terms of price and technology, the level of after-sales service is crucial. When purchasing a cisco Gigabit Switch, we also need to compare the quality of after-sales services of each brand, including three-pack services, on-site services, product maintenance, product maintenance, and costs.

Considering the localization service factors, it is recommended to choose domestic manufacturers of products, such as Huawei, TP-LINK and so on. In addition, when purchasing a cisco Gigabit Switch, you should also pay attention to whether the product has a layer-3 switching capability, whether it supports stacking, and whether it supports Qos/Cos.

Common purchase errors:GB = 1000 Mbps?

When purchasing a cisco Gigabit Switch, many network users mistakenly believe that a switch with a port of Mbps is a cisco Gigabit Switch. In fact, this is incorrect. In the current market, any port with a transmission rate of Mbps is referred to as a cisco Gigabit Switch.

For example, most mainstream products currently provide 10/100/100/1000 Mbps adaptive and 10/100 Mbps adaptive ports, Mbps ports are provided to desktop users, and Mbps ports are used for core switching. In fact, there are not many products with a single Mbps port.

Packet forwarding rate = backboard bandwidth?

Packet forwarding refers to the packet forwarding capacity of the cisco Gigabit Switch, which is generally measured in pps. The packet forwarding rate of the cisco Gigabit Switch generally ranges from several Mpps to dozens of Mpps, an important indicator of packet forwarding rate is the backboard bandwidth. However, the backboard bandwidth refers to the maximum data volume of a cisco Gigabit Switch. The wider the backboard bandwidth, the larger the packet forwarding rate.
