vostro 3550

Vrodhcp DHCP configuration is required by many administrators. After configuring dhcp in Cisco 3550 and discussing it on the network, according to the "ip helper-address dhcp server ADDRESS", the project finds that the client cannot obtain the ip address from the DHCP server, I recently configured 3550 as a DHCP server relay proxy. I was also confused for a long time. Later, I searched for information onlin

3550 Configuration of DHCP, the network has many discussions, but most of the existence of errors and omissions, according to the configuration of the online introduction of "IP helper-address DHCP server address", the project found that the client can not obtain the IP address from the DHCP server, I also recently configured 3550 as a relay agent for the DHCP server, initially puzzled for a long time, and

As Windows 8 is still in the pre-release version, major software vendors and online service providers are gearing up for development and testing to prepare for Windows 8 compliant programs. At that time, I wrote a piece about the construction Bank Network Silver Shield is unable to use the problem and its solution. With the official listing of Windows 8, the compatibility of WIN8 with Web sites and software is commendable, thanks to the collaboration and efforts of various software providers. Fo

This article describes in detail how to implement targeted routing for Policy Routing, and provides detailed configuration procedures and command line operations from the policy routing function to the interface application. The following article will introduce you in detail. The topology is as follows: Because of the design requirements, different address segments on the aggregation layer must be routed to different endpoints on the core layer to achieve load balancing. The topology is not com

A number of people asked how to configure 3550 as a DHCP server, because at that time, when configuring 3550 as a DHCP relay agent by the way to test A to configure 3550 as a DHCP server and passed, so here the configuration process is written out for your reference. Network environment: A 3550EMI switch, divided into three vlan,vlan2 for the server network, na

Comprehensive introduction to layer-3 Switch configuration instances: with detailed command explanations, have you ever encountered layer-3 Switch configuration? Are you familiar with the detailed commands? Does your layer-3 Switch often make your machine difficult? Let's take a look at the layer-3 Switch configuration Article below. All problems can be solved. This article describes in detail the instance Description: Comprehensive layer-3 Switch configuration more comprehensive layer-3 Switch

desktop connections, and 24 10/100 ports. In this way, medium-scale companies can upgrade their LAN to a higher-performance gigabit Ethernet, and the cost increase per port is not large. When connected to the new Catalyst 3550-12T multi-layer Gigabit Ethernet switch, the Catalyst 2950T-24 switch provides an integrated copper Gigabit Ethernet solution for medium market customers who need to upgrade their fast Ethernet trunk. Excellent Service Quality

Recently, the organization decided to upgrade the network device. All the originally used 3Com switches, and all the computers were assigned to two VLANs. Except some computers use fixed IP addresses, other computers obtain the address through a DHCP server. After the network is upgraded, the network center router remains unchanged. Most access-level switches are switched to Cisco Catayst 3550 or Cisco Catayst 2950, but the following situations occur

restrictions. For example, the source port and target port of the 2900XL switch must be in the same VLAN, and some switches do not support RSPAN. For more information, see the device documentation. When configuring SPAN, we need to provide the source port, VLAN number, and target port. 4000/6000 CatOS switch: Setspan6/176/19 // SPAN: the source port is 6/17, and the target port is 6/19. 2950/3550/IOS/6000IOS switch: Monitorsession1loca

When configuring a vswitch, note that the IP address, gateway, domain name, and other information set for the vswitch are used to manage the vswitch, you can save a lot of trouble for your future work. 3550 When configuring dhcp, there are many discussions on the network, but most of them have errors and omissions. After configuring "ip helper-address dhcp server ADDRESS" according to the instructions on the internet, the client cannot obtain the IP a

Cisco 3750 switch stack configuration points 3750 stack is a real stack, the Catalyst 3550 series uses StackWise technology, it is an innovative stack architecture, A 32 Gbps stack interconnection is provided to connect up to nine switches and integrate them into a unified, logical, and optimized device for convergence, in this way, customers can deploy voice, video, and data applications with greater confidence. 3750 adopts the backplane stack mode.

Some friends who are new to ACL (access control lists) may be unfamiliar with vacl. This article will provide a comprehensive description of the use of vacl on Cisco COs and iOS vswitches.The same as the regular access list, dynamic access list, and self-reverse access list, vacl is a part of the ACL extension application. It defines information traffic based on three layers or more, the corresponding parameters are used for two-layer VLANs. Vacls are mostly used in hardware, and are much faster
