2950 switch

CISCO has become a leader in the switch industry, so I have studied the comprehensive performance of CISCO switch 2950. I would like to share it with you here, hoping it will be useful to you. Fixed installation of wire speed fast Ethernet desktop CISCO switch 2950, can prov

Ethernet switches are still commonly used. So I studied the comprehensive performance of the Catalyst 2950 remote Ethernet switch. I would like to share with you here, hoping to help you. Cisco's long-distance Ethernet switch can leverage existing copper infrastructure to meet high-bandwidth application requirements. Catalyst

I wanted to experiment with two switches, but after entering one of the switches through the console port, I found that the iOS file of the exchanger was missing.Should normally enter the switch after the first into the user mode, and the prompt should be ">", and now the prompt has become ":",This is the equivalent of a computer without the operating system, all the hardware into a heap of scrap metal, no practical use, so now to do is to restore the

password to enter the privileged mode, and the original configuration content is retained.Operation steps: 1. Prepare the console cable and connect the Super Terminal. 2. Restart the switch (because 2950 does not have a power switch, you can directly unplug the power cord and connect it back.) 3. Press the MODE key at the start to enter the

Speed-limiting switches are typically on three or more switches, and the new switch model two-tier device since 2008 can achieve the QoS speed limit of 1Mbps, such as the Cisco 2960 series switches. After this, most of the domestic standard two-layer switches can be long speed limit, the accuracy of the basic can reach 1Mbps, such as ZTE's standard two layer, H3C standard two layer can do. Older Cisco standard two-layer switches such as
