cisco catalyst 3550 switch

In Cisco 3550, dhcp configuration is often discussed on the network, but there are mostly errors and omissions. According to the configuration described on the internet, after "ip helper-address dhcp server ADDRESS, in the project, I found that the client could not obtain the IP address from the DHCP server. I recently configured 3550 as the DHCP server relay pro

Management engine even in the communication between single slot ports. All cards have a certain bandwidth per slot, allowing the network administrator to design a system that provides full dedicated server bandwidth and switch applications, and delivers high-performance, oversubscribed desktop gigabit connections. Modular centralized design allows customers to take advantage of the high performance of their online card investments, which apply to th

The following describes a unique solution on the Cisco Catalyst Switch to prevent the harm of the worm in a very economical, effective, and scalable way, this greatly saves a lot of company losses.

Define the server. On other Cisco devices, the default RADIUS port is 1645/1646 (authentication/accounting ). On the Catalyst, the default port is 1812/1813. If you use CiscoSecure or a server that is in contact with another Cisco device, port 1645/1646 is used. Run the following command to define the server: set radius server #. # auth-port 1645 acct-port 1646
