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

The naming rules for Cisco switches are more complex than the naming rules for routing,Look at these:ws-c2960-24tc-l, WS-C2950G-24-EI-DC, Ws-c2960-24tt-l, Ws-c3750g-24ts-e, Ws-c3750g-24t-s, We didn't find them on the switch, we just saw the Catalyst 2950 series and wrote it all: The Cisco Catalyst 2950 Series, which means the Cisco switch 2950 series, Catalyst Th

third-tier switches are more commonly used, so I studied how to use the third layer of exchange to ensure data security, here to share with you, I hope to be useful. Jiangxi 39 Yi Gong Co., Ltd. Backbone network topology is a multilevel star Gigabit Ethernet. A high-performance switch, Cisco Catalyst 4006, with multiple gigabit and gigabit ports is placed in the center room of the Science building to serve as a backbone core switch. The company's pr

Overall planning of the programme Now take the Cisco Catalyst 1900 switch, Cisco 2600 router As an example, write out the detailed configuration of the scheme. Planning for VLANs (1) The working mode of the VLAN: We use static mode to specify VLANs for switch ports. (2) ISL Tags: ISL (Inter-Switch Link) is a protocol between switches, between switches and routers, and betwe

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

the lack of a graphics catalyst (CCC), We need to download the graphics catalyst, recommended to go to the website download (more suitable for our graphics card), We click on the mouse to "drive and support", choose your own system version, here I choose "Windows 7 32", click to enter Check the version number, and then click "Download". After the download

network structure is: The campus connection between the choice of multimode fiber, to the audio-visual building as the center, radiation to other buildings, the horizontal cable in the building using Super five-type non-screen twisted cable. The Cisco Catalyst8540 13-Slot Multi-service routing switch serves as the central switch, and the level two switch is Cisco Catalyst 5505 and Cisco Catalyst 2924. Sec

Generally, the data distribution and size of each stage may not be the same, the global shuffle partition settings can only be optimal for some or some stage, there is no way to achieve all the stage settings of the global optimal.This series of performance and usability challenges for shufflepartition prompted us to think about new ways to automatically set the appropriate shuffle for each stage based on the amount o

network security events, these actions that respond to security events are sent to the vswitch for precise port disconnection. To achieve this kind of association, the switch must be able to support functions such as authentication, Port Mirroring, forced stream classification, process count control, and port lookup. Equipment redundancy is also important Physical security, that is, redundancy, is the guarantee for safe network operation. No manufacturer can ensure that its products do not fail
