how to configure cisco 2950 switch

There are still many things worth learning about Cisco switches. Here we mainly introduce the Cisco switch interface mode. In a Cisco switch network, there are four main types of interfaces in the LAN that are ultimately stable: access/trunk/multi/dot1q-tunnel. 1. access: it

In a Cisco switch, how does one configure QOS speed limit? How to restrict BT download? This blog will use detailed examples for your explanation. Instance 1: QOS speed limit problem on CISCO switches It is used to control the bandwidth of a leased line user on a vswitch. The vswitch is usually at 10/100/1000 or three

Branch switches.The Cisco switch can support any media as a trunk line. To achieve relay, you can use its unique isl tag. Isl (inter-switch link) is a protocol for transmitting vlan information and vlan data streams between switches, between switches and routers, and between switches and servers, by configuring isl encapsulation on the port directly connected to

Cisco Catalyst Switch configuration and maintenance method. Today's Catalyst Switch topic discusses the introduction of the History st6000 series and the introduction of the Catalyst Switch 5000 Series. There is no difficulty. Hurry into the Wireless World. LAN switches have evolved from a HUB-based LAN shared in the t

be built, while CD signals often exist. In addition, if one end of the X.25 line fails, and the other end of the X.25 line is often normal, so if the normal end of the router has data transmitted to the abnormal end, the router considers the X.25 line to work normally. Therefore, there is no backup line at all.　　Steps for displaying backup Method Configuration　　1. Correctly configure trunk lines for normal communication2. Correctly

version: STP (Spanning Tree Protocol), RSTP (Fast spanning Tree Protocol), MSTP (multi spanning Tree Protocol). Spanning Tree algorithm (STA): to elect the Root bridge, which has the smallest bridge ID (that is, RID), the bridge ID is determined by the bridge precedence (priority) and bridge MAC address together calculate the path to the root bridge, by port overhead (cost), Bridge ID (bid= Bridge priority + Bridge MAC address ), Port ID (pid= port priority + port number)

The port rate between switches and switches, between switches and routers, does not meet the actual rate and requires tying more than two ports together to load balance and prevent single points of failure.1.

Layer-3 Switch for Cisco switches Although single-arm routing solves the communication problem between different VLANs, it also has its fatal defects: -The single arm itself is the Backbone link of the network, which is easy to form a network bottleneck. -The sub-interface relies on physical interfaces, and the application is not flexible -You need to view the route table for each vlan forwarding, wasting
