attaches the host port number to the group Destination Address GDA) list. Similarly, when the switch hears an IGMP exit request, it moves the host port number from the entry of the content addressing memory CAM table. By supporting hardware IGMP listening and implementing IGMP listening configuration through the Cisco cluster management suite, the Catalyst 2950 vswitch provides excellent performance and ease of use when controlling and managing LAN m
have to worry about the failure to find the Console port. On the top or side of the port, there will be an identifier similar to "CONSOLE", as shown in 2.

In addition to location differences, the Console port type is also different, the vast majority of the Catalyst 1900 and Catalyst 4006) are using RJ-45 Port 2 ), but there are also a few using DB-9 serial port such as
Catalyst 3200 and Catalyst 4006), and others on the back panel (such as Catalyst 1900 and Catalyst 2900XL). Typically, the modular switches are mostly in the front panel, while the fixed configuration switches are mostly in the back panel. However, there is no need to worry that the console port cannot be found, and t

For the connection between the switches, there should be more familiar two kinds: first, is stacked, two, is cascaded. The cascading approach is relatively easy to create bottlenecks between the switches, while stacking technology can increase the backplane rate, can eliminate the bottleneck of the connection between the switches, but by the limitations of distance and so on, and the number of switches is more restrictive. Cisco's switch clustering technology can be seen as a combination of tier
There are many users who use Cisco switches. When selecting their products, it is a headache to see Cisco switch models. Here we mainly explain how to quickly understand these complex Cisco switch models. The product line of the 2900 series is very long. Some of them are common 10/100 BaseTx Cisco switches, such as C2912 and C2924, some are with Optical Fiber interfaces, such as C2924C with two 100 BaseFx ports, and some are modular, for example, C 29

In the network World, Cisco System Inc. Nobody knows, no one does not know. With its IOS (Internet operating System), Cisco is an absolute leader in the multiprotocol router market. Currently, nearly 80% of the routers in the Internet are from Cisco. In fact, in addition to the main product of the router, Cisco also has a full range of network equipment, including hubs, switches, access servers, soft and hard firewalls, network management software and so on. Cisco is very aware of the new techno
configuring the switch via the console port is the most common and basic management and configuration that network administrators must master.
The different types of switch console ports are located in the same location, some on the front panel (such as Catalyst 3200 and Catalyst 4006), and others on the back panel (such as Catalyst 1900 and
Traditional Ethernet frame header, of which 802.1p occupies three places. 802.1p extends the 802.1d Protocol. A maximum of eight priority levels can be provided with a three-bit priority. 802.1Q uses VI (VLAN Identifier, virtual network Identifier) bits to identify which virtual network the transmitted frame belongs. A total of 12 VI bits are supported. The maximum number of virtual networks supported is no more than 4096. 2. qoS in the queue management LAN is used to check when a communication
a maximum of 2Gbps Full-duplex transmission bandwidth. Both of these methods support stacked redundant connections, respectively. When using daisy-chained connections, redundant connections are made by connecting the top switch to the bottom switch with a stacked cable. When point-to-point connection is used, it is accomplished by using the 2nd 3508 switch.
