Cisco recently released 802.11 of its support products. The network giant said it would help enterprises easily deploy the next-generation wireless LAN and use 802.11n to bring a wider range and higher throughput to wi-fi. According to Ben Gibson, head of Cisco mobile solutions, the market is accelerating the adoption of Wi-Fi technology and is seeking to move forward to the latest wireless LAN standard, 802.11n, the following products and services were created: a modular 802.11n access point, A

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

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.

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

In the middle of a Cisco switching network, how do I find out which port of the switch is connected to the IP address of a machine? The most convenient and quick way is to use the User tracking function of the CiscoWorks 2000 LMS network management software. The graphical interface is clear at a glance. If you do not have this software, you can use the following manual analysis method to find the answer. Example network: the core switch is 6509 switch

The server setting of the Cisco router log is a high-end problem. In the process of using it, we need to constantly find a better way, but for linux, many people are not very clear about it. How does one set linux to a Cisco router log server? To achieve unified log management, including 2950 6509 3550 2611 and Huawei 3526 switches.Method 1: QUOTE: RedHat: vi/etc/sysconfig/syslog: Change SYSLOGD_OPTIONS = "-m 0" to SYSLOGD_OPTIONS = "-r-m 0", and then

changed to 672 to 500 to facilitate calculation and integer-based understanding. After understanding this, I suddenly found that the selection of network devices was so simple. I only need to predict the total number of nodes in the network and the bandwidth and traffic requirements, then the required vswitch performance models and vro models are ready.Note:Many of the current devices are layer-3 switches. The parameters we see are for layer-3 and layer-2 modules respectively.For example, the

-group 1 mode desirable non-silent! 2. Duplex Mode Mismatch:Duplex Mode Mismatch is a common problem. Due to the failure of automatic rate negotiation and duplex mode negotiation, this problem often occurs. you can use the show interfaces command to view the speed and duplex mode of both ports. later versions of CDP can also send a warning log before the port is in the err-disabled status. in addition, abnormal Nic settings will also cause mismatch of the duplex mode. solution: if the two parti
