how to configure cisco 2950 switch

"Introduction" is a Cisco with Stackwise Plus? Catalyst? The 3750-E series switches are an enterprise-class, stand-alone, stackable wiring switch family that supports the deployment of secure converged applications and maximizes investment protection based on the development of network and application requirements. By combining A/V and power over Ethernet (PoE) configuration with a Gigabit Ethernet uplink,

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

The implementation of the multi-port Cisco switch module is a common problem. How to configure the Cisco switch module, any problems related to ports will be fully resolved in this article. Cisco

found again. This time it is smaller. It is disconnected when it is uploaded to 16 Mb. The system still prompts timeout and write error. After careful analysis, we finally found the key to the Cisco switch failure. Two transmissions, 32 MB at a time and 16 MB at a time. Even the number of bytes is not bad, it is certainly not a problem with the transmission line. After checking the information, TFTP (Trivi

, and multimedia support for enterprise intranets. Introduction to the Catalyst5000 Series Cisco's ipvst5000 series Cisco LAN switches, in addition to the Catalyst 5000, also include four models: Catalyst 5002, Catalyst 5500, Catalyst 5505, and Catalyst 5509, all of which are Catalyst 5000 enhanced. The old device used in this project is a Catalyst 5509 switch. Taking the common Catalyst 5509 as an example,

. Breakthrough Cisco switch cluster technology You can use the new Cisco switch cluster technology to achieve scalability and manageability beyond the stack. You can configure any Catalyst 3500 XL series or 2900 XL series standard or enterprise

I am eager for the first time to switch between vlan routing and nat addresses of Cisco switches. I am very energetic and have an undefeated spirit. I am ready to continue to answer questions during multiple rounds of interviews. My little brother squashed his eyes and took out the bottom of the press box: If my company has two Internet interfaces, A and B, respectively. The following vswitch divides multip

a switch, we will inevitably enter an incorrect command, for example, if we type one more letter or one less letter, I thought the switch would prompt this command error, but a strange thing happened at this time. The system didn't prompt us for a command error, but made a connection to it (that is, the command was executed the same ), 3550 # beijing. That is to say, the

Disable forwarding of a specific MAC address on a cisco SwitchIt is really annoying to see other illegal DHCP in the LAN. In addition to the dhcp snooping method, you can also directly disable the mac address! The MAC address of machine A is 00-01-02-03-04-05, which is connected to port F0/3 of Switch B, port F0/3 is in VLAN3. Currently, forwarding of A is blocked on port B. You can set the following accord

1. Unplug the power cord of the vswitch, press the switch Mode button, and re-plug the power cord of the vswitch. Release the Mode button after the LEDs on Port 1x are off. 2. For the Catalyst 2940/2950 L series: Unplug the power cord of the switch, hold down the Mode button of the switch, and re-plug the power cord of
