Otherwise, I would be discouraged from using xmodem to transmit 41 MB of IOS. Because I used xmodem to transmit a cisco Switch Failure IOS, it would take more than two megabytes. It took two hours. 41 MB? It can ta

Cisco is the main force in the entire vswitch. Its products are doing very well in the market. The following article will detail some of the usage skills and precautions of Cisco switches, in many organizations, the core backbone switches are primarily Cisco. In the process of debugging and maintaining Cisco switches,

In CatOS, it should be written as 00-06-29-73-12-1d.
used much in actual projects. 2. for mid-end products, refer to mid-end products. The 3500 series of mid-end products are widely used and representative. The basic features of the C3500 series switches include a backboard bandwidth of up to 10 Gbps and a forwarding rate of 7.5 Mpps. It supports 250 VLANs, IEEE 802.1Q and ISL Trunking, and CGMP/Gigabit Ethernet switches, optional redundant power supply. However, the biggest feature of C3500 is management and gigabit. In terms of management featu
gigabit and routing capabilities are not very important, so the two 2948 switches are not used much in actual projects. 2. Mid-range products Let's look at the mid-end products.

A: catalyst 4000 does not support ISL and 802.1q. Cisco switch
